The M113 entered service as the primary Armored Personnel Carrier for mechanized infantry formations around 1960. It also quickly became clear that its fundamentally sound design would be useful for many, many other roles, either in specialized variants or just for general usage. For instance, there are ambulance variants, and command post variants. The M113 was replaced as the prime carrier of the mechanized infantry by the M2 Bradley beginning in the early 1980s, but the M113 still soldiers on in these support roles. In fact, in the Armored Brigade Combat Team of today, there are more M113 variants in use than there are tanks or Bradleys.

But even though the upgrade of the fleet to the current M113A3 standard greatly improved the mobility of the carrier, it is rapidly becoming clear that the power, speed, cross country mobility, and ability to support command and control systems has reached the practical limit. It is time for a replacement vehicle.
The Army sees a need for roughly 3000 new vehicles. They want a new general purpose carrier, a mortar carrier, an ambulance, a command post, and a couple other versions.
What the Army doesn’t want is a clean sheet design, leading to a long, drawn out development program. The Army’s Future Combat System and Ground Combat Vehicle programs were disasters, costing billions of dollars in development, but not leading to any actual production contracts.
In fact, the Army knows exactly what it wants. It wants the basic hull and machinery of the Bradley, minus the turret. A simple armored box, into which the appropriate mission equipment can be mounted. This stuff isn’t rocket science. In fact BAE Systems, the maker of the Bradley, has been trying to sell the Army various Bradley derivatives for years. And the basic Bradley chassis is quite sound, also serving as the basis for the M270 Multiple Launch Rocket System. Further, Bradley suspension and powertrain components were used to upgrade the AAV-7A1 Amtrac fleet, and are upgrading the M109A6 Paladin Integrated Product improved self propelled 155mm howitzer. Sharing that basic platform eases the supply and logistics train.
Of course, the DoD acquisition system is a nightmare. The Army can’t just pick up the phone and order what they want from BAE. They instead have to go through the internal acquisition process justifying the need for an M113 replacement, which takes time, manpower and money to realize something that everyone already knows. Then comes the fact that, when you start talking about spending a couple billion dollars, you have to take bids for contracts. So the Army published a Request For Proposals, or RFP. And in spite of very narrowly tailoring the RFP to pretty much say “we want to buy turretless Bradleys from BAE” the Army still ran into some trouble. General Dynamics, makers of the Stryker family of vehicles, protested to the Army that the RFP unfairly excluded Stryker variants from the competition. And they do have at least some point. At least one heavy BCT deployed to Iraq with Stryker ambulances in place of its M113 ambulances. But while a Stryker ambulance might have been suitable for Iraq, the Army can very easily see scenarios where such an ambulance would not be able to keep pace with tanks and Bradleys. That’s the whole point why it wants turretless Bradley vehicles.
General Dynamics has recently decided it won’t tie up the issue with a protest to the GAO (which would tie the program in knots for years). Instead, it will likely lean on friendly representatives in Congress to at least give them some small slice of the pie in future budgets. After all, the Army may want turretless Bradleys, but it can only buy what Congress tells it to.
