One of the jobs I had when I was a young troop was Dragon Gunner. By the time I was a Dragon Gunner, they were pretty long in the tooth and not very highly thought of. But think about this: back before you could buy a pocket calculator, the Army had fielded a guided missile that could reach out and destroy a tank over half a mile away, and yet was small enough and light enough for one man to carry.
The Dragon, or M47 Medium Anti-Armor/Assualt Weapon, was first issued in 1975. It was a man portable guided missile that used wire guidance technology called SACLOS-Semi-Automatic Command Line of Sight. Basically, when the missile was launched, it trailed to very thin coppper wires behind it. It also had a flare in the rear of the missile. The sight unit tracked the flare and saw if the flare was in the crosshairs or not. If the missile was not in the cross hairs, the sight sent a signal by way of the wires for the missile to go up, down, left, or right. All you had to do to guide the missile was keep the crosshairs on the target. But that is easier said than done. Dragon gunners spent a lot of time practicing this skill. Since the missile cost about $10,000, they didn’t let us shoot all that many for practice. Usually, a device that fired a powerful blank cartridge was used. One of the other things that made it tough to aim was the launch itself. The missile used a small rocket to propel itself out of the launch tube.
