The M1 is the principal Main Battle Tank of the U.S. Army. Designed during the 1970s, it combines new armor, a high powered engine and a computerized firing system that allows it to hit stationary and moving targets while driving at top speed. Experts say the tank is possibly the best combination of firepower, mobility and protection in the western tank arsenal. The tank's low silhouette and armored panels offer increased protection. Recent versions have high-tech steel and depleted uranium armor.

He is equipped with three periscopes, one of which can be replaced by a special scope for night driving. Sophisticated electronics help pinpoint the enemy. Gunner designates a target, uses a laser and computer to determine range and trajectory, then opens fire. Armored doors and bulkheads protect crew from ammunition or fuel explosions. Tank is also equipped with automatic fire-extinguishing system.
