Happy Birthday to… the Tank!

The History Channel’s “Today in History” page notes that September 6 is the birthday of the tank:

On this day in 1915, a prototype tank nicknamed Little Willie rolls off the assembly line in England. Little Willie was far from an overnight success. It weighed 14 tons, got stuck in trenches and crawled over rough terrain at only two miles per hour. However, improvements were made to the original prototype and tanks eventually transformed military battlefields.

So happy birthday to the ultimate weapon system…. The Tank!

As the article notes, the first tank had some detail issues to work out.  The British wouldn’t put the first into combat until a year later, in Septmeber 1916.

See.. those early tanks doubled as infantry fighting vehicles.  AND they had their own smoke system!

Another Cold War Flashback: T-55

I promise… this is the last video from this year’s open house at the American Wartime Museum.

I think this is a T-55AM2 turning laps on the demo field.  But I must admit my armored vehicle recognition has slacked over the years.

The T-55AM2 is a Czech offering to upgrade the dated, obsolete T-55.  The upgrades at least give the old clanker a chance against modern anti-tank weapons.  The upgrade package includes applique armor on the turret and hull, a side panel to protect the external fuel tanks, upgraded power pack, thermal protection for the main gun, suspension adjustments, better tracks, and a smoke grenade system.

AWM 20 Aug 11 144

Yes, smoke grenades.  In the “old days” Soviet tanks used a TDA smoke generating system that simply dumped fuel or oil onto the exhaust manifold. I recall during one of our threat briefs circa 1991 an instructor clarified this solution by saying, “its just stupid, but that’s the way Ivan wants it!”

AWM 20 Aug 11 139

Also on display at the open house was a basic T-55 in Czech colors.

AWM 20 Aug 11 282

The basic T-55 was a formidable adversary in its day.  With 120mm frontal armor and a 100mm main gun, the Soviet tank had advantages over the contemporary American M-47s and early M-48s.  The low silhouette gave the T-55s some tactical advantages.   But that advantage came at a price – main gun elevation and depression.  I would also add, the T-55 is the most cramped tank I’ve ever taken a run in.

BMP-1 Running Laps, Clearing Mines

Another video from the American Wartime Museum open house last month.

A BMP-1, dressed out in late Cold-War colors.

Gotta like the simulated “react to mine” drill.   The political officer stated this was only a drill and that had this been a real mine field, the team would have used the “stomp the mines out” method to clear the path, thus saving the vehicle.

He also ordered me to pass along this video showing the BMP-1 doing real work.

Note the comparison to knock-off capitalist copies.

Ivan Could Swim!

A Craig tank posting again.  Here’s another video from the American Wartime Museum open house:

Many will jump to compare the PT-76 to the M551 Sheridan.    But the Russian tank had been around some 15 years before the American tank even did test laps. While the American tank used a highly advanced (perhaps too advanced) hybrid gun-missile armament, the PT-76 used a tried-and-true 76mm main gun.  The gun fires both high velocity armor piercing (HVAP) and high explosive anti-tank (HEAT) rounds.  A 7.62 caliber coaxial machine gun complements the main gun.

AWM 20 Aug 11 075

PT-76 on Display

The Russians kept the PT-76 in production through the late 1960s.  All told over 5000 rolled out of the factories.  Production variants introduced better NBC and night vision systems.  A few PT-85s were produced with an 85mm main gun.  And experimental versions featured 90mm or anti-tank missile armament.

The PT-76′s design put emphasis on amphibious capabilities.  In fact, the PT-76 came with water jets to allow speeds of 6 mph when swimming.

AWM 20 Aug 11 077

Water Jet Exhaust

In addition to great amphibious capabilities, the PT-76 had a roomy interior and good cross country mobility.  But the tank’s armor was only good against rifle-caliber fire.  And the main gun lacked any stabilization.  You wouldn’t want to go toe-to-toe with enemy tanks.  However, the PT-76 was designed to operate and exploit the fringes of a defense line where enemy tanks were not supposed to be.

In Soviet service the PT-76s armed reconnaissance companies in line divisions and tank companies in the marine divisions.  Russia retains a significant number of the PT-76s.  Here’s an old documentary forwarded by the political officer (can anyone translate what he’s saying?):

With over 2000 exported, many nations around the world continue to operate the amphibious tanks.  Examples manned by the North Vietnamese participated in some of the few tank-vs-tank battles in the Vietnam War.  In fact, PT-76s were the first to fall victim to TOW missiles.

While technically the tank COULD be airdropped or air-transported, the Russians opted to use the ASU-57 and ASU-85 self-propelled guns in airborne formations (and later BMD series recon/carriers).

AWM 20 Aug 11 078

Rear Deck of PT-76

Speaking of the ASU-85, that weapon used the chassis of the PT-76, with of course an 85 mm gun fixed in a superstructure.  Other systems using the PT-76 chassis include the BTR-50 amphibious carrier, the ZSU-23-4 self-propelled anti-aircraft gun, missile carriers, and various support vehicles.  The Chinese improved the basic design into their own Type 63 tank.

AWM 21 Aug 10 087

Same Tank from Last Year's Open House

Certainly there are some features of the PT-76 that make me wish the US Army or Marine Corps had procured something similar.  On the other hand, the American habit of misusing light armor would make any “Yankee” version a death trap.

Glory to the heroes of the Patriotic War!

Another video from the American Wartime Museum open house.  This time a Ruskie!

The T-34/85 was perhaps top on the list of medium tanks during World War II.   With a diesel engine and 85mm gun, the T34/85 compared well against the contemporary American M4 Shermans.  While the German Panther tanks could beat it one-on-one, the T34/85 were rolling out of the factory at a rate of 1,000 a month!

AWM 20 Aug 11 236

I liked the living historians (what we call reenactors in high-brow discussions) hanging on the side of the tank.  Sort of conjured up thoughts of Kursk or Berlin.

AWM 20 Aug 11 228

But I bet the guy in white ended up with a hefty dry-cleaning bill.

Best remembered for World War II service, the T34/85 remained in service well beyond 1945.  Like the M4 Sherman, the T34s saw action in Korea and in other places the Cold War ran hot.  Several countries retained T34s right up to the lifting of the Iron Curtain.

The T34/85 running laps was one of two on display at the event.

Impressive armor.

The political officer ordered me to say that – Craig.

Going great guns…

Another repost since I’m too lazy to write anything this morning. 

 

Welcome Reddit readers. Part Two is HERE, and Part Three is HERE.

For an army that has used machine guns for a hundred years or so, we have had remarkably few weapons serve as a standard machine gun. When I talk about machine guns, I mean what the Army calls a machine gun, not Hollywood or the press. A machine gun is a weapon that is primarily designed to provide automatic fire, not just one that can. For instance, the M-16 is an automatic weapon. You can set the selector switch to automatic and pull the trigger. The weapon will fire automatically until the magazine is empty. But it was designed to be used mostly as a semiautomatic weapon, where one pull of the trigger fires one round. Machine guns, which are usually belt fed, almost always fire full auto. Many don’t have any provision for semiautomatic fire.

We aren’t going to go back to the Gatling gun and its counterparts. In many ways, they were considered artillery, and treated as such.

The first really successful machine gun in the US Army was the Browning M1917. This gun fired the same .30-06 rifle cartridge as the standard US rifle, but fired it from a cloth belt holding hundreds of rounds. The big fat thing on the barrel is a water jacket. The water in the jacket cooled the barrel when firing long bursts. How long? Well, when Browning was trying to sell the gun to the Army, he fired two bursts, of 20,000 rounds each.  Right now the Army says that an M-4 carbine is ready for replacement after firing 7,000 rounds over the course of its life.

This ability to place huge amounts of automatic fire on target was very much appreciated by  the infantry during the trench warfare of WWI. And it still had a place long after that. With a range of well over 1000 yards, the M1917 could be used to support our troops during an assault. The M1917 remained in service throughout WWII and the Korean War. The Weapons Company of each infantry battalion had a platoon of them.

The only real problem with the M1917 was that it weighed so much. The gun itself was heavy, then there was the sturdy tripod, water in the jacket and a spare water can, and then enormous amounts of ammunition. It was almost a given that a vehicle would be needed to transport the gun team. As the Army tried to get away from static trench warfare, something lighter was needed that could accompany troops on the move. Since most of the Army moved by foot, this would have to be light enough for a team to carry long distances.

Browning had the answer there as well. By removing the water jacket and placing a perforated cooling jacket around the barrel (to allow cooling air to circulate) Browning considerably lightened the gun. Coupled with a new, lightweight tripod, the new gun was adopted as the M1919. While it could not sustain nearly as high a volume of fire as the heavy, water-cooled guns, it could be quickly and easily moved by a three man team , allowing it to follow troops almost anywhere on the battlefield. The three man team consisted of the gunner, who carried and emplaced the tripod (and then fired the weapon when emplaced), the assistant gunner, who carried the gun (and then assisted with loading the gun when in operation) and the ammunition bearer, who carried additional ammunition, and was armed with a rifle to provide local security while the gun was being emplaced.

While the 1919 couldn’t provide the same volume of fire as the 1917, the gun was still incredibly reliable and capable of laying large volumes of fire upon the enemy. It’s vastly superior portability also meant that it would be up front where the fight was. Normally, each infantry platoon had two machine guns assigned. The M1919 was such a solid design, it remained in service from 1919 up until the early 1960′s. (actually, the initial basis of issue was 2 guns per company, but by the end of WWII, most platoons had two guns-ed.)

During WWII, the Wehrmacht (the German Army) was mostly equipped with bolt action rifles. To make up for this lack of firepower, each squad was centered around the excellent MG42 light machine gun. This provided the bulk of the squad’s firepower. The Americans were greatly impressed with this gun. After the war, the Army looked to find a gun that would be lighter than the M1919 and more portable. They wanted a gun much like the MG42, firing from either a tripod or, usually, a bipod, using a buttstock.

After years of development, the Army adopted the M-60 machine gun as its standard medium machine gun. It had a number of “improvements” over the MG-42. It was chambered in the NATO standard 7.62mm x 51 cartridge. It deliberately had a lower rate of fire, to reduce the ammo needed and diminish the need to constantly change barrels.

While the M60 was issued in the same two guns per platoon manner as the M1919, it was often used in the role of a squad automatic weapon, much like the MG42. The M60 became iconic, seen almost every night on the evening news during the Vietnam war. But the M60 wasn’t without its own problems. It was somewhat fragile. When I was an M60 gunner, one of the real issues with the weapon was the various leaf springs on the gun. Many would fall off, even when properly installed. For instance, it wasn’t unusual to lose the leafspring that held the trigger group onto the gun. Soon thereafter, the trigger group would try to get away. We had to lace the guns together with parachute cord or safetywire. This made it almost impossible to disassemble the gun for clearing jams. The feed tray was made of stamped metal and was vulnerable to being damaged from relatively slight impacts. If that happened, the gun wouldn’t feed at all. And the gas piston could be inserted backwards during assembly after cleaning, leading to a gun that wouldn’t fire on full auto.

After trying several modifications to the weapon, the Army finally adopted a new medium machine gun, the M240. This is the American name for the Belgian MAG58, which, ironically, lost the original competition to the M60. The M240 has been in use as a vehicle mounted weapon in the US for about 30 years, but it was only in the mid-1990′s that the services started using it as a standard infantry weapon.

The 240 is a solid, well designed gun. It weighs just a little more than the M60, but is very resistant to damage and very easy to maintain. It is incredibly reliable. If your gun is jamming, UR DOIN IT RONG!

It is ironic that after the development and use of machine guns for 100 years, the Army is using a gun first designed over 50 years ago, one that initially wasn’t adopted largely because of the “Not Invented Here” syndrome.

Part 2 will cover some of the other Great Guns of the US Army.

Humvee With Chimney for Safety Draws Military’s Interest – NYTimes.com

An innovative chimney to vent blasts from buried bombs could make the Humvee safer and bring the most popular military vehicle since the Jeep back from the sidelines in Afghanistan.

The Humvee fell out of favor in Iraq and Afghanistan as homemade bombs, the biggest killer of American troops, ripped through its light armor and turned it into a death trap.

But recent blast tests show that Humvees built with the new chimney could provide as much protection as some of the heavier, and more costly, mine-resistant vehicles that have replaced them in many uses.

via Humvee With Chimney for Safety Draws Military’s Interest – NYTimes.com.

The “chimney” lets a major portion of the blast vent next to the gunner’s cupola. I can’t imagine gunne’s will be thrilled with that.

The Humvee was never really intended to be a combat vehicle. It was originally designed to be a replacement for the jeep and a series of pick-up truck sized vehicles.  It has proven remarkably adaptable, but even so, there’s no way it will ever win the race between armor and warhead size.  But even purpose built vehicles in the size range of the Humvee will also suffer from the limitations inherent in setting a small size on a vehicle.

If you want tank like protection, you end up with a tank.

Tank Battles

I’m feeling poorly today, so here a “best of..” post from way back in the very early days of the blog.

I wrote earlier about bringing enough gun to the fight, but not too much. A prime example of this was the M-1 Abrams tank.

When this tank debuted, people were aghast at the cost. What they didn’t realize was it was acutally the result of an extreme cost cutting program. For 20 years, the Army had been cooperating with Germany to develop a sucessor to the M-60 series of tanks, but each iteration had become too complex and too costly. The Army finally decided that they would develop a tank using technology shared with the Germans rather than develop a tank to be used by both countries.

One of the sticking points was the main gun. The standard US tank gun was the 105mm M68. The Army thought this was sufficient to defeat current and projected Soviet armor (and were pretty much right).

The Germans had developed the excellent 120mm smoothbore, and wanted both countries tanks to use it. Our Army resisted for a couple of reasons. The biggest was cost. The new gun would have to be license produced here, with associated setup costs. Even more expensive would be providing stocks of ammunition for the gun. The Army had a huge stockpile of 105mm ammunition already. Buying an entirely new stockpile in the tight budgets of the 1970s wasn’t an attractive option.

In the end, the 105mm won-sort of. The decision was to place the M-1 into production with the 105mm, but make provision to add the 120mm in the future. As it turned out, for various reasons, this was a lot harder than anyone expected. Still, partly as a sop to our German allies, and partly over concern about the ability of the 105mm to defeat future Soviet armor, the 120mm was adopted for the M1A1 that entered service in 1988.

One disadvantage of the 120mm was a reduced ammo load. An M-1 with the 105mm carries 55 main gun rounds. An M-1A1 carries 40. As it turns out, however, few tanks will shoot their entire basic load in a single battle. In fact, not a single tank in Desert Storm fired its entire basic load.

Tankers, ever wonder why the coax on your tank has that massive 4000 round load? Because that’s where the designers originally wanted to put the 25mm M242. The only reason it didn’t make it into the final design was cost. Leaving the 25mm out saved about $100,000 just for the gun, and made the fire-control system simpler, and hence cheaper.

American Wartime Museum Open House 2011

Craig here.  I ran this post on my blog earlier today, but figure the audience over here would better appreciate the smell of diesel exhaust and clanking of treads:

The American Wartime Museum holds it’s annual Open House event on August 20 and 21 this year. The event features vintage military vehicles, reenactors, and other displays. The event is free, but you have to register in advance. The event is held outside Nokesville, Virginia.

Were else will you see stuff like a British tank named after that Hallmark holiday in February:

AWM 21 Aug 10 022

British Valentine Tank

Or a real deal Commie tank from back in the days when there was a Berlin wall!

AWM 21 Aug 10 023

Russian/Czech T54/55 Tank

Or a working “Uncle Billy” M4 Sherman tank:

AWM 21 Aug 10 016

What’s Old is New Again

For almost a decade, the Army has been focused on low intensity conflict (a very relative term!) in Afghanistan and Iraq. Now, there’s no such thing as low intensity to the guy in a firefight, but the fact remains that Afghanistan and post-invasion Iraq were fought primarily against insurgent forces, not near-peer competitors fielding what we tend to think of as modern armies.

But with the reduction of US troops in Iraq, and the possible drawdown of US forces in Afghanistan in the near future, the Army is again looking at the need to train for higher intensity conflict, what they now call “full spectrum operations.”

YAKIMA – Capt. Dan Ferriter is used to facing elusive insurgents on his combat tours of in Iraq and Afghanistan. They’ve been the Army’s main enemy during his six-year career, planting roadside bombs and taking shots at American soldiers from hidden places.

Now the former Ranger is training to fight a different foe, but one just as lethal for American forces who have been emphasizing counterinsurgency warfare for nearly a decade.

Ferriter, a Stryker brigade officer from Joint Base Lewis-McChord, is getting back to basics and preparing to go to war against another military rather than a shadowy network of terrorists.

“This is pre-9/11,” the dirt-covered captain said last week during his company’s drills at the Yakima Training Center. “The guys that were in the Army pre-9/11 are starting to get few and far between.”

Ferriter is in the desert of central Washington this month with the 3rd Brigade, 2nd Infantry Division. The 4,000-soldier brigade has deployed to Iraq three times since 2003 – it was the first of the Army’s eight Stryker brigades – but it doesn’t have another mission to Iraq or Afghanistan on the horizon.

It’s using this opportunity to build skills for what the Army calls “full-spectrum operations.”

“The hard part is not losing how good we’ve become at (counterinsurgency) and making the right balance,” said Ferriter, 28, of DuPont.

Back in my day, this was meat and potatoes, bread and butter stuff. Mechanized force on force warfare was the focus of much of the Army from the immediate post-Vietnam era through the end of the Cold War. And we were very good at it (see: Storm, Desert).

It wasn’t until the messy and bothersome interventions in such garden spots as Somalia and the Balkans that the Army even began to realize that it might have to fight in ways it didn’t really want to, in urbanized terrain, against non-state actors such as terrorists and insurgents. As an institution, the Army was slow to grasp some of the difficulties of fighting in that environment. Stability and support operations doctrine was slow to evolve, and to say that many troops early in Iraq had only On the Job Training would be accurate.

Faced with the need to deploy large numbers of troops to Iraq and Afghanistan in these counter-insurgency campaigns, the Army tailored the pre-deployment training of its forces to their next deployment, and focused on the roles and missions those units would be tasked with. That’s only right and proper. We call it battle focused training for a reason. And it would be immoral for the Army to not provide the best suited training for its soldiers as they were spun up to deploy.

But while the Army was largely focused on those two theaters, the rest of the world didn’t go away. The possibility of conflict with near-peer nations hasn’t disappeared. And a lot of the skillsets that troops in combat arms units used to practice have withered from disuse. As the article notes, (and as Esli and LTC F note in a pair of excellent comments left at NepLex’s post on this subject) the people who grew up doing “full spectrum” operations are largely gone. The Army, despite excellent retention, has a lot of personnel turnover, and the “tribal knowledge” has been diluted by that.

An armor or “heavy” infantry officer in the days of “AirLand Battle Doctrine” had a fairly predictable career path, much of which allowed the doctrine of maneuver warfare to sink into his bones. A tour as a platoon leader, then either as a company XO or specialty platoon leader, time as a company commander, then as a junior staff officer at battalion or brigade, time for advanced military and civilian schooling, time as a senior staff member or battalion XO, and then on to battalion command. All that time, he’d be using the same basic doctrine, and learning ever more complex ways to utilize the basic tools available to him, and how the various units and staff sections, and supporting arms and services worked hand in hand to achieve victory against a large maneuvering enemy force, usually heavy with armor and motorized infantry.

Today, while our young officer might have many of the same assignments, his focus has been elsewhere. As Esli will attest, not since his days as a company commander has unit training been focused on fighting enemy tanks.

It is about time the Army return to this capability. One of the reasons we have faced insurgent forces is that our enemies realized in the wake of Desert Storm that a stand up fight against us was a good way to get your ass kicked. But as we have focused more on the counter-insurgency fight, some potential enemies may start to feel froggy enough to take us on under certain circumstances. We need to be prepared for that.

A couple of complications lie ahead, not just from the lack of experience throughout the force in maneuver warfare.  One, the Army has transitioned form a division based organizational structure to a brigade centric organization. The Army had 50 years of experience in learning how to fight a division in high intensity warfare. It has almost no practical experience with the new brigade concept. It will learn (and they DO have the practical experience of actually using the brigade organization in the real world for a decade now), but there will certainly be some bumps in the road, and some surprises.

Second, the Army isn’t facing an “either/or” situation, where it gets to choose between a “heavy” fight, or a COIN campaign. The new doctrinal name “full spectrum operations” recognizes that any heavy fight will almost certainly also involve a lot of stuff the Army would prefer not to deal with, such as insurgents, paramilitary forces, the need to perform stability and support operations simultaneously ( or nearly simultaneously) with combat operations, and interfacing with civilian populations, allied forces, and non-governmental organizations, all while trying to fight a fast moving heavy opponent.

The practical effect of that is, they have far more tasks that units simply must train for. And there is only so much time, money and other resources available to train units. Finding the right balance, as CPT Ferriter says, is going to be the hard part.

Uniformly Stupid? Part 2

See Part 1 here.

I’m on the road, so I’ll be doing some “best of” posts. Right now, this is the most searched for post. 

While most people in the Army spend just about all their time in a working uniform like the ACU, there are occasions when something a little more formal is needed.

Since the late 1950s the standard Army Service and Dress uniform for most soldiers has been the Army Green Uniform. Folks in the Army almost universally refer to it as “Class A’s”.

When the uniform jacket is removed, the Army Green Uniform can be worn as the Class B uniform, suitable for most office environment jobs. When I served as a recruiter, most days we wore the Class B.

No, that's not me...

No, that's not me...

The problem with the Army Green Uniform was simple. It was ugly as sin in church. There was an alternative, however, one with a great history dating back practically to the first days of the Army. The Dress Blue Uniform.

Female Officer and Male Enlisted Service Dress Blues

Female Officer and Male Enlisted Service Dress Blues

There’s a reason why the trousers are a different shade blue from the coat. Back in the days of the Old West, when cavalry troopers wore the blue uniform as there work clothes, they would routinely remove their coat, roll it up and carry it strapped to the back of the saddle. The trousers faded from the sunlight and wear and tear, but the coat didn’t. Hence the difference.

Service Dress Blues were always an optional item for enlisted personnel. You could buy them, but you didn’t have to. Since they cost a lot of money and there were relatively few occasions to wear them, most junior folks did without.

Back in 2005 or so, the Chief of Staff of the Army made the decision to do away with the Army Green Uniform and modify the Blue uniform to replace it.The new variations are shown below.

The Army Blue Uniform

The Army Blue Uniform

Personally, I wish they had done this about 25 years ago. I always hated the Green Uniform, and as soon as I could, bought a set of Blues. And anytime I had a chance to wear them, I did. One fairly common occasion was the “Dining Out”. A Dining Out is when a unit, typically a battalion, has a formal banquet, with spouses and sweethearts invited*. This is a social occasion run on military lines- the colors are presented, the chaplain gives the invocation, there are a couple of (usually brief) speeches, and maybe some awards and recognitions. Then there is usually some dancing. The important thing is, your best girl gets a chance to put on her best dress and go out to be seen. Chicks dig that.  Since a lot of guys didn’t own Dress Blues, they made do with the Army Green Uniform with a white shirt and a bow tie.

Your author, center, in Dress Blues, flanked by two friends in Class A's.

Incredibly, I managed to save this picture, but lost the picture of my date. You’ll have to take my word for it that she was stunning. Really. The two guys in the photo were great friends and fellow warriors, but neither was all that attractive….

Army Acquisition Woes

From the mid 1970s through the early 1980s, the focus of the Army’s major acquisition program was on rebuilding the post-Vietnam force to face the challenges of the Soviet threat to Western Europe. In those days of extremely tight budgets, the Army had to exercise a remarkable degree of self discipline to decide which programs were really needed, and to shepherd them from conception to production and fielding. The Army’s challenge was to get the greatest possible increase in combat power with the smallest possible cost in dollars. Congress and the public were in no mood to support massive spending on defense, but the Army was in desperate need of new equipment. The only way the Army could convince the nation to support it was to have a well thought out plan, not just for acquisition, but how the Army would use that equipment, and why the programs supported had to be funded to implement that strategy.

In the end, as what later became known as the AirLand Battle doctrine began to gel, the Army focused on The Big Five- The M1 Abrams tank, the M2 Bradley fighting vehicle, the UH-60 Blackhawk utility helicopter, the AH-64 Apache attack helicopter, and the MIM-104 Patriot surface to air missile system.

All five of these programs were controversial at the time, as each had a high unit cost, but by the early 1980s, it was clear that each program was successful, and while expensive, a wise investment.

Since the Big 5, there hasn’t been any successful major Army modernization programs (with the possible exception of the Family of Medium Tactical Vehicles, the replacement for the old deuce-and-a-half and 5-ton trucks) . If you look at the major weapons for the Army today… It’s still M1s, M2s, UH-60s, and AH-64s, with Patriot still providing air defense.

The Army’s major procurement programs since then have mostly been a tale of woe. The poster child for letting ambition and requirements get out of touch with the state of the art, and the needs of the Army was the LHX program, which was originally designed to produce a family of helicopters that would replace the Huey, the Cobra, and the Kiowa. In the end, it was trimmed down to a light attack helicopter, the RAH-66 Comanche, but it was so hideously expensive, and filled such a niche role that it was superfluous to the real needs of the Army. But a program that runs for 20 years and costs untold billions of dollars is hard to kill. It took SecDef Rumsfeld a couple of stabs at the beast to finally slay it. Other programs that seemed to run forever included the Crusader howitzer project and the gigantic Future Combat System program.

The only procurement programs the Army seems to be able to run with anything resembling competence are those that are conducted outside the normal channels. such as the Stryker program (which was seen as an interim program until FCS came along) and quick reaction purchases such as the MRAP vehicle fleet and a lot of the personal equipment that the Army couldn’t find money for until it was in a shooting war (in spite of the fact that most of those purchases were relatively cheap).

Defense Professionals magazine has an OpEd on the Army’s programmatic woes.

This record of failure is all the more striking in view of the Army’s relative success with rapid acquisition of a variety of platforms and systems. The best known are the MRAP and M-ATV protected vehicles. But in many ways the acquisition of soldier clothing and individual equipment has been even more successful. PEO Soldier has demonstrated the ability to rapidly develop and deploy a range of new capabilities including remote weapons stations, enhanced low light/night vision goggles, man-portable robots, laser designators and cold weather clothing. Collaboration with third-party product integrators has resulted in an ability to rapidly meet a wide range of urgent operational needs for clothing and equipment at relatively low cost.
The question still unanswered is whether the broken peacetime acquisition system can be fixed. The Army has two major procurements coming soon. The first is the Ground Combat Vehicle (GCV), the successor to the Future Combat System. The second is the Joint Light Tactical Vehicle (JLTV) intended as the replacement for the lighter and less well protected Humvee. The GCV program has already been halted and restarted once. There are recent reports that the JLTV may be afflicted with that dreaded disease which has killed many Army programs in the recent past: changing requirements. The cost of the individual GCVs and JLTVs may also be a “killer.”

One of the hallmarks of recent troubled or failed programs in not just the Army, but all the services has  been “families” of systems. Every time one of the services starts a program that is bound to be expensive, they add requirements to the capabilities in order to justify spending so much money on the program. But that drives up the technical challenges and the cost, both of research and development, and the eventual unit price and the life-cycle costs. And the added “capabilities” demanded add technical risk to the program, which always results in cost overruns, and adds additional oversight, reviews, and changes to the program, all of which add greatly to the cost and timeline of the program.

Examples of this bloat in requirements abound. The VH-71 Marine One helicopter program, the JSF, the Navy’s LCS program, the FCS family of systems, you name it.

The current Ground Combat Vehicle system program is setting itself up for failure in a similar fashion. The Army seems to have convinced itself that it can procure a common vehicle to be used both as the successor for the Abrams tank and the Bradley family of vehicles.  While the Stryker family of vehicles comes in a wide variety of variants, the Army explicitly recognized that all variants would be compromises of one sort or another. But perfect tomorrow is the enemy of good enough today. But the GCV program doesn’t seem to recognize that.

Unless and until the Army can impose a disciplined set of realistic requirements, and stick to them, for each system and avoid at all costs overreaching and bloat in its programs, it is destined to fail again. While the Army and the other services have to operate under the ridiculously onerous DoD 5000 series of procurement regulations, they have also been their own worst enemies in acquisition. There are many members of Congress on both sides of the aisle that are willing to spend limited resources to fund the Army, but only if the money is well spent. And until the Army can show a clear and compelling case for its procurement strategy, they won’t have earned that goodwill, from either Congress or the American people. The leadership of the Army would be well advised to study the history of the Big Five.

Vehicle BDAR

Battle Damage Assessment and Repair. When I opened youtube last night, it recommended these two videos to me.

Vehicle Graveyard
Tank graveyard

In the first video, most of the vehicles are obviously total losses, and almost certainly a fair number of our troops died in the attacks.

But the second video shows quite a few vehicles that were damaged beyond repair… that is, beyond what  a unit can repair. But having been dragged off the battlefield, there’s a fair chance a good number of tanks and Bradley’s shown have been (or at least, could have been) rotated through the Army’s depot level maintenance system, and restored to service. And if our forces in Iraq had been truly pressed for vehicles, some probably could have been run through BDAR. By salvaging parts from multiple vehicles, and by accepting some degradation of capability, some of the tracks in the second vid could have been pressed into service.

Each mechanized battalion in the Army had two “spare” vehicles assigned to it, called “floats”. Almost like a loaner car from the dealer when you bring your car into the shop. If your Bradley (or tank) was damaged or broken down, you’d use the  “float” until your own vehicle could be restored.

That was the concept, anyway. When my unit was in Desert Storm, we actually tended to use the “floats” as rolling spare parts bins.  If one of the primary tracks in the company needed a spare part, such as a 25mm main gun, they’d turn the busted gun into maintenance, and steal the gun off the float.  We had several vehicles that ended up having to cannibalize parts off the float. It was a pretty disreputable looking hoopty that crossed the border a discrete distance behind us. No main gun, no TOW launcher, no ISU (Integrated Sight Unit), short-tracked on one side because someone else needed a road wheel arm, no radios or antenna mounts. And no rear ramp. Let me tell you, moving that thing was a massive pain!  But by depriving one vehicle of its parts, the rest of the company crossed into Iraq with reasonably fully functional vehicles.

Cavalry Spurs

XBrad here. This post generated some interest in the Cavalry and its traditions. We’ve got another guest post by Esli addressing that topic.  Esli is an active duty career Armor officer with tours as an enlisted infantryman and a commissioned Armor and Cavalry officer.

Stetson and spurs are the hallmarks of the Cavalry, the army’s scouts and reconnaissance units. So how exactly does a young cavalryman get them? Stetsons are purchased: spurs are earned. This is a long-standing tradition in the Cavalry and no Trooper’s uniform is complete without them. True cavalrymen still recount the stories of their “Spur Rides.”

There are two ways to earn your spurs. Spurs come in gold for combat and silver for demonstrated excellence in the skills of the cavalryman. Gold spurs can be awarded by the squadron commander to any Trooper (assigned or attached) who “rode with” his squadron during a wartime deployment.

Earning the silver spurs is generally harder. This includes prerequisites, satisfactorily completing the spur ride, and then surviving the ceremony. This sequence of events, once complete, will become one of the most memorable events in an army career, though strangely the brain wants to forget many of the details!

My spur ride began as the executive officer of a reconnaissance squadron. This is a guy with a lot of time on his hands (sarc off) so I was worried about pulling out of my duties long enough to do it. I spent a couple of days training up for the event. I had already completed the PT test and weapons qualifications to the appropriate standards, and was ready to perform as a “spur candidate” or “maggot” in spur-holder parlance. (Spur holders control your destiny. If they say do it, do it. If they don’t say anything, then you don’t do anything. They mete out punishment, guidance or rewards equally. Well, no rewards, just punishment.)

Due to an incredibly busy schedule, our spur ride was a relatively short 30-hour event. Nonetheless, it was the most physically demanding thing I have ever done in 22 years in the army. We started about 0400 and spent some time getting smoked before moving to a field for a PT test in ACUs. After the PT test (which no one passed…), we returned to the squadron area for an inspection of our equipment and a written test on reconnaissance tasks. Then it was back on the LMTVs for a ride out to the field.

The spur ride consisted of day and night land navigation courses. Without getting lost, my legs totaled 18 miles. Moving as a team of five, we went from point to point, testing on scout tasks at each. While we waited at each station, we were physically and mentally smoked in various unmentionable ways. Some of the tasks included map reading and land navigation, calling for and adjusting indirect fire, estimating range, patrolling techniques, reacting to contact, combatives (hand-to-hand combat tasks), weapons disassembly/reassembly, NBC, 1st Aid, carrying simulated casualties, call for MEDEVAC, prepare a Helicopter Landing Zone, constructing a machine-gun range card, conducting negotiations, employing hand grenades, camouflage, and other tasks. Not only did we walk everywhere, but many of these tasks were physically demanding efforts for 1-2 hours each under simulated combat conditions.

Depending on speed, some teams got an hour for dinner and to prep feet for the night land navigation lane, which continued through the above tasks, but in the dark using Night Vision Goggles.

By the end of the night lane, my 5-man team had dwindled to 3. We finished with about an hour break, but I stayed awake since I was unsure of whether the spur-holders would wake us up or not. I stretched, ate, rubbed my feet, and put on Vaseline and fresh socks.

Finally it was time for the last event; a foot march (18 miles down, only 12 more). So far, we had been carrying 30-40 lbs (including team gear of radio, litter, aid bag, and a signal panel). For the foot march, we put on our rucks. My load was about 92 pounds. This foot march took me just about 4 hours, and I managed to finish ahead of the bulk of the pack. At the end, for the first time in my life, I really wanted to get an IV, but no-go; the medics checked me and determined that I didn’t need one, even though plenty of guys were getting stuck.

At last, we climbed into the back of the LMTVs, went to the squadron area, and I worked a regular duty day (as best I could) until I was released to go home and get in dress blues for a formal spur ceremony and dinner. (Walk 30 miles and stuff your feet into low-quarters. Ouch!) Most of this will go undescribed, though it did involve a horse made of 2x4s and yelling “You ain’t CAV” to which the audience replied appropriately with “You ain’t ***!!”

Because our real spurs hadn’t arrived for the first ceremony (good job, S4), we were privileged to have a second one in which we were stood on our hands in front of the squadron while our sponsors put our spurs on our upside-down heels. I was honored to be both the oldest guy to get them and the recipient of the first spurs ever awarded by that squadron.

NOTES:

1. For those familiar with EIB, the spurs are much more focused on teamwork, CAV esprit, and both mental and physical determination, as opposed to the exactitude required to complete a series of individual tasks as in the EIB. My EIB was harder, technically, and earned at about the old-school rate of 10%, while the spurs were incredibly difficult, physically, but earned at about a 75% pass rate.

2. CAV is a state of mind, not a job. Any Trooper can compete, regardless of MOS.

3. CAV is gender-neutral, and our female Forward Support Troop commander earned hers. (XBrad- The testing is gender neutral. The actual MOS for Cavalry is a combat arms MOS and excludes women by law. Some units allow females to participate in EIB testing, and they and any non infantry personnel who successfully complete the testing are awarded a certificate of completion. Only Infantry personnel may actually be awarded the EIB)

XBrad again. While Cav spurs aren’t an officially recognized award like the Expert Infantryman’s Badge, they are highly cherished (I actually had a Cav trooper as a 1SG once, and you can bet his spurs were prominently displayed in his office). And while the testing may not be battle focused, all the tasks do have a real world application.

More on the TOW missile

So, this post showing some excellent ‘splodey was pretty popular. And TOW missile video posts have long been a mainstay here.  But it wasn’t until I started looking in the comments that I realized I have never actually done a post about the history of the TOW, how it works, and its variants. Craig kindly laid the groundwork with a post on missiles in the age before TOW, so lets carry on from there.

The TOW and the older SS10 and SS11 missiles that Craig posted about all shared a couple of characteristics. They were all armed with a HEAT warhead to defeat tanks, and they were all wire guided.

The older missiles used a guidance technique known as Command-to-Line-of-Sight (CLOS). Simply put, The gunner launched the missile, and a flare on the back of the missile showed the gunner where it was. He then steered the missile along his line of sight to the target. As long as he saw the flare heading at the target, all was well. Typically, the missile was controlled by a small joystick, and the guidance corrections the gunner made were sent along a pair of very, very thin copper wires trailed from the missile. While this was pretty nifty at the time, it was awfully low tech, and required very intense training for the gunner to achieve any proficiency.  The gunner had to keep track of both the target and the missile, and “fly” the missile to the target. Hard enough on  a stationary target, but against a moving target like a tank, it was very difficult indeed.

Building on that basic concept, the Army capitalized on its technical know-how and the miniaturization of electronics in the ’60s to introduce a much improved technique: Semi-automatic Command-to-Line-of-Sight (SACLOS).

The big difference between CLOS and SACLOS is the way the missile is commanded. In SACLOS, and optical sensor in the gunner’s sight tracks the missile’s flare (or “beacon”) and measures its deviation from the line of sight, as determined by the crosshairs in the sight. When the missile guidance set senses a deviation, it would send the correction, rather than the gunner having to make a correction. In effect, all the gunner had to do was keep the crosshairs on the target for the time of launch until impact. This was much, much easier than trying to manually fly the missile to the target.

The original TOW missile was the BGM-71A. It was a revolutionary improvement over previous missiles.  The missile was stored and launched from a sealed  fiberglass tube, that protected it from the elements and rough handling.  It was optically tracked from either a ground launch platform or a stabilized sight on a helicopter, and it was guided via copper wires, hence the acronym TOW. The orignally TOW had a 6″ diameter missile body, with a 5″ diameter HEAT warhead, and a range of 3000 meters.

Pretty soon, it was clear that the missile had sufficient energy to fly further than 3000 meters, and by simply adding more wire, the range was increased to 3750 meters.  The next version, I-TOW (Improved TOW)  added a standoff probe to the warhead to make sure it detonated the optimum distance from the target.

Increases in Soviet armor lead to an improved missile, and more importantly, an improved guidance set. This TOW 2 featured a larger 6″ diameter warhead, a slightly modified probe, and critically, added a thermal sight system to the launcher, meaning for the first time, the TOW could be used at night. The TOW 2 incorporated a xenon beacon at the rear of the missile to allow this thermal sight to track it at night or in low visibility.

With the advent of  reactive armor, the TOW2A was designed with tandem warheads. The first warhead would detonate the reactive armor, while the second would punch through the now exposed site.

TOW 2B was a different approach. As mentioned in the linked video, it uses two downward firing EFPs to punch through the thinner top armor of tanks. The TOW2B overflies its target, never actually striking it. The gunner merely keeps the crosshairs on the target, the guidance set handles the “offset” aim for him.  By giving later versions of the TOW2B an aerodynamically improved nose, and increased wire capacity, the TOW2B Aero has increased range to 4500 meters.  This is the current production anti-armor model of the TOW for the US Army, though enormous numbers of earlier TOW2 models are sill in the inventory and issued.

With the current fights in Afghanistan and Iraq facing little in the way of armored threats, the limitations of the HEAT warhead became an issue. While a HEAT warhead is better than none, it has little real anti-personnel capability. This has lead to the development of the BGM-71H, which is similar to the TOW 2A, except the HEAT warheads have been replaced by a blast/fragmentation warhead better suited to killing troops and destroying bunkers.

In addition, a wireless variant of the TOW2B is in production.

Recently, the ITAS (Improved Target Acquisition System) has begun replacing older TOW2 sights in ground mounts. This has a much improved thermal sight, not only improving accuracy, but also serving as  a very handy surveillance tool for infantry units.

TOW missile with ITAS in Afghanistan

The TOW has proven to be a remarkably adaptable weapon system, with a wide range of improvements incorporated over the years. Improvements to both the missile, and the guidance sets have kept it a very viable system on the modern battlefield. But there are some limitations to further growth. Primarily, the fixed diameter and length of the missile imposed by the launch tube size means that there is only so much space to grow. Also, given that limitation, the missile remains fairly slow, meaning the time from launch to impact is quite lengthy, over 3o seconds to maximum range. This can give the enemy time to either shoot back or attempt to flee.

Even with these limitations, the TOW is a very effective system, and there are no current plans to replace it as the heavy anti-armor missile system.

More Armored Recon – The Lynx, Offspring of the M113

Another contender armored recon category in the 1960s, a variant of the M113 offered by FMC, Corp., rolled out in 1966. The FMC offering, called M113 ½, appeared for all purposes a shrunken version of the Armored Personnel Carrier (APC). With only four road wheels (vice five on the APC), the M113 ½ stood just over six feet tall.

The M113 ½ featured a redesigned front hull and a rear mounted engine. The crew consisted of a driver and observer seated side-by-side, along with the commander at the main weapon station on a .50-cal machine gun. FMC’s ACRC weighed over eight tons, but could reach over 40 mph on roads. Power came from a 6-cylinder diesel.  Like the M113, the ACRC offering was amphibious, with a trim vane that deployed in front of the front hull plate.  Armor on the M113 ½ was slightly better, due to the front 60-degree slope mostly, over the base M113.

On paper, the M113 ½ seemed like a good bet, particularly considering commonality with the M113 family. However with the M114 already in production, the US Army opted not to pursue the M113 ½. That didn’t stop FMC from offering the vehicle for sale to other countries. In 1966 the Royal Netherlands Army purchased the first of 260 modified M113 ½.  In the mid-1970s  most received a turret mounted 25mm Oerlikon KBA cannon.

The Dutch retained the side-by-side seating for driver and observer.  Note the side crew hatch (seen open here).  Aside from the turret, very similar to the type evaluated in the US.

The M113 ½ attracted orders from Canada also.  FMC modified the basic offering for Canadian specifications, placing the observer behind the driver in tandem, with a 7.62mm machine gun (either a M1919 Browning or FN MAG machine gun).  With this move, the commander’s station moved to the right, retaining the original .50-cal machine gun.  And the Canadians dispensed with the side hatch.

Canadian Lynx

Thus configured, the Canadians call the M113 ½ the “Lynx.”

Canada, the Netherlands, and FMC, who continued marketing the vehicle for a while, proposed and tested armament upgrades.  But size restricted a significant weapons enhancement.  Like the M114, the Lynx could not pack enough firepower to pose a threat to any enemy armor force encountered.  But, in the two NATO countries which used the vehicle cavalry doctrine differed from that in the US.  A small, lightly-armed, thin-armored vehicle measured well against Canadian and Dutch expectations.  Both armies used the M113 ½ into the 1990s, but gradually replaced the type with wheeled scout vehicles.

A nice, detailed walk-around of the Lynx is posted here: Lynx Walkaround.

Armored Recon – Wrong Turn with the ACRC

In the earlier post, I noted the 1950s requirement for the Armored Command and Recon Carrier (ACRC).   To meet the ACRC requirement, Chrysler offered an armored car while General Motors’ Cadillac Division proposed a small tracked vehicle.  The Army’s long standing bias killed the Chrysler proposal, and Cadillac moved forward with tracked prototypes under the designation T114.

Appearing in 1958, the T114 used a small block Chevy 283 V-8 gasoline engine (a military version of the same engine found in cars of the time).  Cadillac used many other “off the shelf” components.  I cannot find firm documentation, but some suggest suspension components were from the M56 Scorpion, also built by Cadillac (although certainly NOT the road wheels). The tracks were “continuous band” somewhat reminiscent of the old half-track type used in World War II, and also similar to that used on the M56.

T114 Prototype

The T114′s crew included a TC, observer, and driver, with a jump seat for a fourth crew if needed.  The prototype weighed under seven tons and stood just short of seven feet tall.  With the front mounted engine, the turret sat to the rear of the fighting compartment.  The river sat in the left front and an observer’s station was to the right side.  The Army tested several armament configurations, to include some with a mind to the anti-tank role.

T114 Prototype with Autoloading 106mm Recoilless Rifle

But after full testing, the Army requested some changes before production.  Production ACRC featured a round, swing opening rear hatch.  As a cost savings measure, the main gun chosen was a .50-cal M2 machine gun, mounted on a pintle outside a large commander’s copula, instead of the turret.   Repositioned to the back right of the crew compartment, the observer’s position gained a top hatch and .30-cal machine gun.  An inch and a quarter of aluminum protected the crew from light arms and shell fragments.

The track was amphibious, transportable in theater support cargo aircraft of the era, and air-drop capable.

CH54-A Carrying M114

M114 under a Sikorsky S-64 (CH-54)

Entering production in 1962, the initial M114 model used the same V-8 car engine of the prototype. That’s why the “rumble” you hear in this video sounds familiar:

All told Cadillac produced just over 1200 of the ACRCs in the next few years.  Early on, an M-60 machine gun replaced the older .30-caliber for the observer.  About mid-way through the production run, a new traverse and elevation system allowed the TC to work the .50-cal while buttoned up, necessitating the nomenclature change to M114A1.  A non-factory modification replaced the .50-cal with a 20-mm M139 Hispano-Suiza cannon.  Thus armed the original M114s became M114E2 while those with the improved main gun mount were M114A1E1.

M114A2

M114A2 with 20mm Cannon

In armored cavalry units, scout teams used the M114s.  A scout platoon of the time included a squad with two sections with two M114s each (four total). While the intent was a mix of 20mm and .50-cal armed M114s, this was not always met.  The platoon leader rode in his “command” M114.  The rest of the platoon consisted of an infantry squad in a M113, a M106 self-propelled 4.2-inch mortar, and three M-60 tanks. Airborne units differed, of course, using the M114s in conjunction with M56 Scorpions and jeeps.  Higher up in the formations, company commanders and battalion commanders in armored units rode in M114s configured as command tracks.  Apparently with the short production run, none of the M114s ever saw use in the ambulance or gun towing roles.

Front View of M114

In service, the shortfalls of the M114 stood out in comparison to the M113 Armored Personnel Carrier.  The V-8 engine, while sufficient for a family car, was not strong enough for a fighting vehicle.  The M114 reached 36 mph on roads, slightly slower than the base M113s.  The front hull overhang presented problems when negotiating ditches.  Low ground clearance between the tracks, required to keep the height down, left the M114 prone to “bottoming out.”  And the 20mm gun suffered from poor reliability.

PROSPECT PARK MEMORIAL 5

Close Up of the Tracks

Further, the “continuous band” track arrangement did not stand up well to the field.  When a band broke, the crew had no replacement options.  In peace time, they had to wait out the maintenance team.  In war, they’d have to abandon the vehicle!

Perhaps the hardest criticism of the M114 I’ve read was about space.  Cramped, the crew compartment lacked room to carry additional mission equipment or internal spall armor.  Certainly no room for ATGMs then entering the inventory, and thus no option to “up arm” the M114 as other countries did with their scout vehicles at the time.

But the Army had the M114 on hand and used it.  Large numbers went to Europe and Korea to arm the front line divisions there. Forty went to Vietnam, some going to the Army of the Republic of Vietnam (ARVN).  In addition to shortcomings mentioned above, the M114 proved no match for enemy mines.  While withdrawn from combat, the forces in CONUS, Korea, and Europe continued to use the little ACRC.  In the late 1960s as the M551 Sheridan tank arrived in sufficient numbers the M114′s days were limited.  In 1973, Army Chief of Staff General Creighton Abrams ordered the M114 out, officially replaced by scout-configured M113s.  But proving bureaucracy is stronger than steel, or a general’s directive, M114s clung to the property books until the close of that decade.

Released from TOEs, most of the M114s became range targets.  Anyone who’s visited Fort Irwin’s wonderful maneuver area has seen a number of these.  Several M114s became “gate guards” or went to other static displays.  And a few found their way to police forces, where their gasoline engine and thin armor was much less a liability.  XBrad featured a police-modified M114 in an earlier post.

In hindsight, the M114 was not only a failure but a wrong turn.  As the commercial says, there’s only one original jeep.  The M114 was the Army’s attempt to “SUV” the jeep concept – too small to haul anything significant or worth shooting, yet too large to hide.  And with respect to the maneuverability seen in the video lined above, road performance and cross-country performance are two different things.  Any scouting vehicle needs the later and, when cornered, trade punches with the “big boys.”  The M114 could do neither.

For those seeking more information about the M114, take a look at Eaglehorse (2-11 Cavalry) web site’s piece and the Tankmaster’s walk-around.

Armored Recon – The US Army Way

XBrad provided an excellent overview of the problems with employing armored vehicles in airborne operations.  And we’ve mentioned several Cold War vehicles designed to address the challenges of balancing protection, mobility, and firepower – the M56 Scorpion, the M50 Ontos, and the M551 Sheridan.  Designers built each of the weapons mentioned around an anti-tank function – each adapting its unique main armament to fit the role.  In a larger context, the airborne experience during World War II highlighted a need for those sky-soldiers to deal with enemy armor.  All of which hits upon the broader topic of light armored vehicles (and their validity on the battlefield).   Contemporary to these airborne designs (the 1950s and 60s) the US Army introduced light reconnaissance vehicles to serve both airborne and armored formations.

The World War II experience weighed heavily on design requirements.  At the end of the “big war” each armored division included a reconnaissance squadron and infantry divisions had a recon troop.  The basic building block of these recon forces was a platoon with six jeeps and three M8 “Greyhound” armored cars.  Three of the jeeps worked as mounted scouts, while the other three were prime movers for 60mm mortars.  The M8 cars, with their 37mm guns, provided overwatch support. In theory that is.

AWM 21 Aug 10 059

M8 Greyhound Armored Car

In the armored divisions, recon squadrons supported the platoons with a company/troop of light tanks (M3A1 Stuart early on, then M5 Stuarts mid-way through, then finally M24 Chaffee tanks by the end of the war).  In addition each squadron had a platoon of M8 Scott self-propelled guns provided indirect and direct support with their 75-mm howitzers.

AWM 21 Aug 10 111

M24 Chaffee

After the war, as is the custom, the Army looked at lessons learned and field performance to reorganize a post war army.  The M8 armored car came off poorly.  While considered useful for road operations, the vehicles lacked the cross-country mobility.  The armor officers complained about the shortfalls of the light tanks, although the M24 impressed many.  It’s 75mm main gun promised to at least put the light tank on par with the medium tanks, in firepower if not in protection.   The M24′s speed and maneuverability exceeded others in its class.  But the Army was not against ALL wheeled vehicles – nobody could deny the utility of the trusty jeep.  In the immediate post-war era, the recon troops lost their armored cars, but gained medium tanks (usually M26 Pershing) to support the light tanks.

The US Army also considered allied and enemy experiences during the war.  The Germans and British used heavy wheeled vehicles extensively in their formations, some of which offered the firepower of medium tanks.  The British maintained these heavy recon forces into the post-war era with a rather successful series of armored cars and light tracked vehicles.  A reconstructed West German Army also opted for heavy recon vehicles.

British Saladin Armored Car

But while the US Army tested several prototypes, no heavy wheeled vehicles made the grade.  (Although the Soviets adopted the “heavy recon” approach, which is another story for another day…)  Instead, the Americans wanted to update the team which had served so well through the heavy fighting in the European theater – scouts mounted in light, fast recon vehicles supported by light tanks.

Experience in Korea seemed to reinforce the findings of the post-World War II analysis.  Recon troops with M24 light tanks and jeeps performed well when supported by M26 medium tanks.   With a mind to improve the light tanks, the Army developed the M41 “Walker Bulldog” light tank, and tested a few in combat during the closing stages of the Korea War.  The M41 featured a high velocity 76mm main gun.  Improving the maneuverability and speed of the M24,  the M41 had slightly thicker armor.  While not airdrop capable (well at least not more than once), the M41 was air-transportable – although only in the larger strategic transports such as the C-124 or C-133.  At 23 tons, the M41 pushed the limits of even early model C-130s.

The “Bulldog” served the Army through the 1950s and into Vietnam.  Only in the later part of the 1960s was it replaced by the M551 Sheridan mentioned above.

AWM 21 Aug 10 052

M41 Walker Bulldog Light Tank

Though supported by M24s and M41s, throughout the 1950s, most scouts rode in jeeps, not much different than their World War II counterparts.  What planners in the mid-1950s wanted was an armored jeep – fast, mobile, and concealable.  Common sense said that the airborne and light scout functions overlapped enough for a common solution.  So the Army issued requirements for a lightly armored, three-man, highly-mobile recon vehicle.  But the jeep had other functions in the armored formation than just scouting.  As the project evolved, many pointed out the same vehicle could meet the need for a commander’s vehicle in armored formations. Other roles required included medical evacuation and anti-tank gun prime mover.  These rather varied requirements merged into the Armored Command and Reconnaissance Carrier (ACRC).

In the next post I’ll look at ACRC vehicle fielded by the Army in the 1960s.

Armored Assault

When I went from being a light infantryman to a mechanized grunt, one thing that quickly struck me we just how quickly the armored fight went. In light infantry, a firefight can easily last hours, battles last for days. In mounted warfare, the firepower and mobility of tanks and Bradleys mean the fight is over in minutes and huge battles may only last a couple hours. Operation Desert Storm showed this point, and the classic example in that campaign was the Battle of 73 Easting.

Battle of 73 Easting

CPT McMasters and his troopers of the 2nd ACR deserve every bit of the accolades they’ve received (and McMasters has since gone on to gain wide recognition both in Iraq as a commander, and as one of the leading intellectual lights in the Army).  They fought a desperate battle under trying conditions and won decisively and magnificently.

But the hidden side of the story that it took 50 years to win this fight. Almost immediately after the end of World War II the Army realized it was facing a huge Soviet Army with enormous numbers of tanks and other armor. The Army soon realized they would never be able to match the Soviets tank for tank, and would have to be able to win by fighting outnumbered. They would need forces that were not only physically faster, but mentally faster and more agile than any opponents they faced. They had to be able to fight in daylight, nighttime, and bad weather.

For a long time, the Army struggled to achieve this overmatch. It wasn’t until after the Vietnam War with the long evolution of AirLand Battle Doctrine and the fielding of the M1 and Bradley family that  this overmatch started to become reality. Combining doctrine with equipment and with the emphasis of tough realistic training provided by training centers like Ft. Irwin, CA and Hohenfels, Germany, complete with realistic opposing forces, provided McMasters and his troopers with the tools needed to not just defeat the Iraqis, but destroy them.

The Iraqis had laid a clever reverse slope ambush, and bad weather prevented US airpower from spotting them. What should have been a devastating ambush instead turned into a brilliant hasty attack. In 23 minutes, a US company eviscerated the heart of an Iraqi armored brigade.  Traditionally, you should attack with a three to one advantage in numbers. In this case, McMasters attacked outnumbered about six to one.

Ironically, Desert Storm was the swan song of the AirLand Battle Doctrine that laid the groundwork for this success. You could not pick a battlefield that was better suited for the US Army at the time. Wide open rolling spaces, plenty of room to maneuver, and little or no civilian infrastructure or noncombatants to get in the way.

Pretty quickly, even before the campaign in the desert was over, the Army realized it was ill prepared to face the challenges of dealing with civilians and built up areas, humanitarian relief, and what we now call stability operations. The Army was ill prepared for the insurgency in Iraq, but they at least had given it a lot more thought in the 90s than they had in the preceding 20 years.

The M1A1s purchased by the Iraqi Army are downgraded from standard US issue.  Most important of the downgrades is the lack of depleted uranium armor.

The Japanese Ontos?

Having discussed the Marines’ Ontos, seems only fitting to mention a very similar vehicle built at around the same time in Japan.

Type 60 Self Propelled Anti-Tank Gun

The Type 60 Self-Propelled Anti-Tank Gun (SPAT) evolved from an early 1950s requirement for the Japanese Self Defense Forces.  Emphasis on DEFENSE.  During the Korean War, the United States encouraged Japan to form a military force to defend the island nation.  The most likely threat in any conventional war was an amphibious or airborne force landing to secure the various straits connecting Russian or Chinese harbors to the Pacific sea-lanes.  As such, the Japanese needed a highly mobile force to contain a moderately armored opponent.  Requirements called for light-weight vehicles capable of rapid transport by train.  Doctrine stressed ambush type tactics to contain then throw back enemy invasions.  Concurrent projects pursued a main battle tank and a self-propelled anti-tank weapon optimized for Japanese requirements.  Both projects proceeded with some deliberation through the 1950s.

SS1-Revised Prototype with Four Rifles

SPAT prototypes from Komatzu Manufacturing (identified as MI or SS1 in some sources) and Mitsubishi Nippon Heavy Industries, Ltd (noted as MII or SS2) rolled out in 1956.  The Komatzu offering used a front mounted 105hp diesel engine, while the Mitsubishi had a 110hp engine in the rear of the chassis.  Both featured two 105mm recoilless rifles (a Japanese derivative of the US M27 recoilless rifle) in a limited traverse mounting.  After testing, Komatzu delivered an additional prototype, the SS1-Revised, with four 105mm rifles.  Mitsubishi delivered the SS-3 with five road wheels.  Then a fourth experimental batch named SS-4, with two M40 106mm Recoilless Rifles (same as used on the M50 Ontos), arrived.  The SS4 also used a more powerful 6-cylinder 150hp diesel engine, mounted in the front.  This emerged as the optimum configuration, and entered series production in 1960 as the Type 60.  In some regards, the Type 60 hearkened back to the “Tankettes” of the 1930s.

Comparison of Production Type 60 (left) and SS1-Revised (right)

Just like the Ontos, the Type 60 used .50-caliber spotting rifles to aid the aim of the main guns.  Also like the Ontos, the Japanese SPAT had a crew of three – commander, loader, and driver.  But unlike the Ontos, the Type 60′s rifles sat in a retractable turret to reduce the vehicle’s height.

Type 60 Self Propelled Anti-Tank Gun

When retracted, the turret traversed only 10 degrees left or right, with an elevation of 10 degrees and depression of 5 degrees.  Deployed in the firing position, traverse increased to 30 degrees, elevation to 15 and depression to 10.

Front View of Type 60

Note also the part welded and riveted construction. The front hull was sloped somewhat, but the sides were vertical. Overall, protection matched that of the Ontos, with only 12mm of armor to defend against small arms and artillery fragments.

Rear View of Type 60

Ammunition lockers provided six rounds. And like Ontos, the crew had to dismount to reload after firing. (And go to Toadman’s Tanks for a good walk-around of the Type 60.)

Type 60 in the Snow

In the field, the eight ton Type 60 reached 34 mph on roads. Turret retracted, the SPAT stood only 4.5 feet tall. Just over 7 feet wide and 12 feet long, the Type 60 was a compact fighting vehicle.

Type 60 During Training Exercises

Komatsu produced over 250 Type 60s.  After the initial “Type A” production, “Type B” appeared with some structural reinforcements.  In 1974 a “Type C” entered production using a liquid-cooled engine with the same power ratings. The only other major modification considered was an auto-loader.  But that was quickly dismissed as overly complicated for the small vehicle.  As late as 2001, 140 of these SPATs remained in service.  But officially all were retired in 2008.

Type 60 on Maneuvers in 2006

Normally, I’d close out with a video or two.  But the only clips I could find feature this guy:

Occasional movie appearances were the highlight of the Type 60s service.

One might easily dismiss the Type 60 as a “knock-off” of the Ontos.  I wouldn’t be so quick.  As mentioned before, the Ontos sprang from US Army requirements for an airborne anti-tank weapon system, only later to see service as a lightweight anti-tank system for the Marines.  Designers optimized the Ontos with enemy counter attacks against envelopment operations (fancy way of lumping airborne and amphibious assault into one category).  In Japan the Type 60 was the defender countering just such envelopment.

As often occurs with weapons development, dissimilar requirements lead to very similar weapon systems.

The Challenge of Airborne Armor

Craig’s recent posts on the SPAT and the Ontos build on an earlier post I did on the M551 Sheridan armored vehicle. All these vehicles had a common heritage. They tried to find a practical combination of mobility, firepower, and protection that could give light and airborne forces greater firepower on the battlefield, while still being small enough to be delivered by air.

Weight is always a critical issue for the designers of armored vehicles. But when you need to be able to drop those vehicles by parachute, it is even more critical. There’s a very finite limit on the amount of lifties an airplane can generate, and trying to get a C-130 to lift more than that will only lead to disaster. And there are so few other airlifters in our fleet, designing an armored vehicle that can only be lifted by C-5s or C-17s severely limits its air-drop utility.

This isn’t a new problem. Almost from the very first days of airborne operations, planners have struggled to match the strategic and operational mobility of airborne forces to firepower that was strong enough to keep them from being swept off the battlefield by conventional forces. The very first airborne units in our Army were limited to small arms, machine guns, and some light mortars. They were superbly trained, but would not have lasted long against determined enemy opposition. By D-Day, US Airborne Divisions had some light artillery and some light anti-tank guns, but no real armor. They were restricted by the lifting capacity of the C-47, which was suitable only for troops and bundled cargo, and the gliders of the time, the Waco CG-4 and the British built Horsa. The British also designed the Hamilcar glider to carry a light tank designed specifically for airborne forces, the M22 Locust. The Locust never saw combat with American forces, and only the slightest service with British forces. It was not considered a success.

But the problem of armored firepower for airborne and light forces had not disappeared. It continued to plague planners in the post-war years.

The British 1st Airborne Division had learned the hard way that lightly armed airborne troops could not attack into the face of armored formations. US planners had learned from that, and sought a way to bolster the strength of airborne forces. The results were mixed at best.

Craig did an admirable job of describing the M56 Scorpion which offered good firepower and mobility, but no protection. And he also described the M50 Ontos, which also struggled to find a balance between firepower, mobility and protection. Next in line was the M551 Sheridan. Like the other vehicles mentioned, it was not entirely successful. It wasn’t a complete failure, mind you. But it suffered from the compromises that had to be made to meet very stringent weight requirements.

So it stood for a long time that the Sheridan was the only armor for the airborne forces. Eventually, old age took its toll on the fleet, and the Sheridans were due for a well earned retirement. The question became, what to replace the with? At the same time, the Army was looking to increase its strategic mobility by converting one of its two active cavalry regiments to a lighter formation that could be moved primarily by air. The 2nd Armored Cavalry Regiment traded in its tanks and Bradleys for lightly armored (and lightly armed) Humvees. This made the unit easier to move, but again, it was pretty light on staying power. The Army took another crack at coming up with an air transportable armored vehicle.

Eventually, after running through a couple different acronyms and the usual program shenanigans, the contractor presented to the Army the XM8 Buford Armored Gun System. It it one of the few vehicles that could honestly be described as a light tank. It was fully tracked, had a 105mm main gun, and was actually fairly small. And it was light enough to be transported and airdropped from C-130 aircraft.

Now, as always, there is the pressure of weight constraints to be balanced against the vehicles vulnerability to anti-armor weapons.  In order to get the M8 weight down to a level that would fit onto a C-130, they had to accept very thin armor, barely enough to stop small arms fire and some artillery fragments. That meant the M8 would be very, very vulnerable to any anti-tank weapons. The solution to that problem was bolt on armor. Normally, any armor on a vehicle actually forms an integral part of the hull, and is part of the load bearing structure. But for the M8, the contractor came up with two additional levels of armor that could be bolted on in the field with simple hand tools, and increase the protection of the vehicles.  For instance, the 82nd might be forced to drop in someplace unpleasant, and to drop, would have to accept the risk of going in with just the lightest armor. But as soon as possible, the additional kits of armor could be flown in and applied. The M8 would never have the level of protection that an M1 Abrams would have, but it would be a good deal better armored than either an M551 or any Humvee.

The development of the M8 was actually fairly smooth (compared to a lot of programs, at least) and the vehicle had just been accepted for service and was just about to be placed in series production when the entire program was cancelled. What happened you ask?

Well, in 1996, the President and the Secretary of Defense told the Army they were going to cut end-strength another 20,000 troops for the Army. The Army was aghast at the cuts, and asked if they could keep some of those troops if they found other savings. And one of the easiest ways to save money was to NOT spend a billion or so on buying the M8. The deal was made.  Eventually, the Sheridans were withdrawn, and the 82nd was without any armor.

With the advent of the Stryker brigade, we’ve seen (and written about) the Stryker MGS or Mobile Gun System. It fulfills much the same role as the M8, but has less armor capability. Nor is the Stryker expected to be airdropped. It is, however, expected to be moved by air, in addition to surface shipping. The same challenges of balancing protection, mobility, and firepower are still with us.

The Firing Port Weapon

Craig has done a fine job of showing us some of the early attempts to replace the M113 that eventually led to the M2/M3 Bradley family of vehicles. Concurrent with that development was a changing doctrine about how mechanized infantry should fight.

When the Soviet BMP-1 infantry fighting vehicle first appeared, US observers were stunned. The Soviets had taken a vastly different approach to mounted combat than the US, and it was a better one.  For years before the appearance of the BMP in 1967, the Red Army had concentrated on developing its BTR series of wheeled armored personnel carriers. While the choice of wheels over tracks could be debated, the actual employment of infantry from them was very analogous to the way the US Army intended to employ its M113 mounted infantry. That is, the armored personnel carrier was primarily there to transport an infantry squad to the battlefield, and protect if from artillery fire en route.

The BMP, however, was designed to accompany tanks in the actual assault on the unit’s objective, and to actually allow its squad to remain on board the vehicle and fight from within the vehicle. In addition to the BMP’s 73mm gun and 7.62mm coax machine gun (and it’s AT-3 Sagger anti-tank missile) the BMP had a series of ports in its sides that allowed the infantry squad on board to use their weapons to add suppressive fires. This was pretty much a “spray and pray” approach. Lots of lead flying around was designed to keep our infantry down in its foxholes and prevent us from taking shots at BMPs with light anti-tank weapons. After the tanks and BMPs had crossed the objective, the Soviet infantry could dismount and mop up our positions by attacking from the rear. Importantly, the Soviet riflemen would be protected from artillery and small arms fire for almost the whole attack.

The US Army decided that was a pretty good approach to mounted combat. So one of the important properties of the successor to the M113 was that it too needed to have firing ports. One small problem though. Unlike the Soviets, who used a folding stock version of the AKM rifle, the US had just adopted the M16 series rifle, and there was just no practical way of handling such a long rifle through a firing port in the cramped interior of an armored vehicle.

Well, the Army wasn’t going to allow something minor like that stand in the way of a doctrinal decision that had already been made. Mounted assaults were the way forward, and the Army would be able to fire from firing ports. So the call went out to actually develop a weapon that would be able to fit in a port and small enough to be handled inside an armored vehicle. So in addition to trying to develop a new armored vehicle, the army had to look to industry to develop a new weapon to go with it. There were a couple different candidates, including a modification of the old M3 “Grease Gun” .45cal submachine gun. In the end, the Army adopted an extensively redesigned M16 action called the M231 Firing Port Weapon (FPW).

381portg

The M231 has a much shorter barrel than the M16, and also doesn’t have a front sight. You’ll notice at the front, it is designed to screw into the ball joint of a firing port.  In addition, because it is intended to be fired form the port, it has no buttstock, just the buffer tube to hold the action spring. But the most significant changes to the weapon are internal.

Whereas the M16 series rifles fire from a closed bolt, and are selective fire, the M231 fires from an open bolt, and is only capable of fully automatic fire.  It also has a much, much higher cyclic rate of fire than the M16 series. Instead of firing at about 600 rounds per minute, the M231 fires at about 1,100 rounds per minute. That little 30 round magazine doesn’t last long.

Originally, there were to be six firing ports on the infantry variant of the Bradley, the M2. There were two ports on each side, and two ports in the rear ramp of the vehicle. Combined with the turret weapons, this would notionally give the Bradley all around suppressive fire.  The need for the squad to be facing outboard while using the M231 dictated the very awkward internal seating arrangement of the Bradley. Each firing port had a periscope through which the soldier was expected to point his FPW and then walk the rounds onto the target. To aid this, the M231 was to be loaded exclusively with the M196 tracer round.  And because the M231 fired from an open bolt, a lot of the gun gases would be released inside the vehicle. To counter this, each position had a flexible exhaust hose attached to a fan and a brass catcher bag (hot brass bouncing all over the place inside a vehicle would be annoying at the very least, and potentially very dangerous). Because the FPW uses an all-tracer ammunition load, that meant that troops had to store their regular load of ammunition, and have a separate supply of ammo just for the FPWs. If you look under the seats of early production Bradleys, there is an ammo pouch under each seat to hold magazines for the FPW.

In the end, very few units ever actually used the FPW beyond mandatory training for it. One reason is that the vulnerability of light armor to anti-tank weapons meant that it was almost always safer to dismount the infantry just short of the objective, and support them with fires from the turret using the 25mm gun and the 7.62mm coax. The other big reason was, you couldn’t hit a damn thing with the FPWs. Trying to walk in rounds while looking through a dirty, dust periscope from the back of a bouncing, swaying vehicle just wasn’t very practical. The one time I actually fired one from the firing port, I just waited for the Bradley Commander to yell “fire!” and held the trigger down. I have no earthly idea where the rounds actually went.  We had targets staked along the side of a road, but after something like a dozen Brads had made firing passes (at a range of about 10 meters) there wasn’t a single hole in any of the half dozen targets.

As later model Bradleys had to have heavier side armor to counter weapons like the BMP-2’s 30mm cannon, and other anti-armor weapons, the firing ports on the side were blanked out by slabs of add-on armor. The firing ports on the ramp of the vehicle remained in place. But given that they have to be removed before the ramp can be lowered, they were almost never used.

Today, M231 FPWs are still in unit armories, but mostly serve one of two purposes. First, they either gather dust and generate paperwork regarding maintenance and security, or they are used as a last ditch, close in weapon by dismounted soldiers, such as those manning the cupolas on up-armored Humvees. They aren’t very effective in that role, but they sure to shoot fast.
