Its armor is designed with a modular armor system that can be easily replaced to protect against the newest threats, making it one of the most include resistant tanks on the battlefield. The M1A2, meanwhile, is powered by a Honeywell LV100-5 gas turbine engine that is both lighter and smaller than the older engine while offering rapid acceleration, and also runs quieter and produces no visible exhaust. The result was progressive increases in the calibre of tank guns, the development of new types of ammunition with greater armour-piercing capabilities, and the introduction of more sophisticated fire-control systems to improve tank guns ability to hit targets. of anti-tank weapons.
