The turret is an armored structure supporting one or more guns - typically a heavy cannon and a couple of machine guns. The hull's job is to transport the top portion of the tank, the turret, from place to place. The hull is the bottom portion of the tank - the track system and an armored body containing the engine and transmission.

Additionally, the track has heavy tread that digs into muddy surfaces, and it never goes flat like a tire. A car grips the ground with only the bottom portion of four tires, but a tank grips it with dozens of feet of track. Tracked vehicles can move easily over rough terrain because the track makes contact with a wide area of the ground.

The internal combustion engine made tracked military vehicles feasible. Earlier tracked vehicles weren't practical in battle because their steam engines were too cumbersome and unreliable. The tank's wheels ride along the moving track, just like the wheels in a car run along the road. The tank engine rotates one or more steel sprockets, which move a track made up of hundreds of metal links. The tank has a cruising range of 426km and can travel at a maximum speed of 67.5km/h.Caterpillar tracks work on the same principle as a conveyer belt. The Abrams M1A2 integrates heavy exterior composite armour and steel-encased depleted uranium armour at the forward hull and turret to offer a high level of protection to its crew. 50 cal M2 machine gun and can store 42 rounds of 120mm, 11,400 rounds of 7.62mm, 900 rounds of 50 calibre ammunition, 32 screening grenades and 210 rounds of 5.56mm ammo. The tank is also armed with two 7.62mm M240 machine guns and a. The main gun of the tank is a manually loaded 120mm XM256 smoothbore cannon, which can fire a range of Nato ammunition against armoured vehicles, infantry and low-flying aircraft. The tank was designed based on the experience gained from the performance of M1A1 and incorporates new technologies to deliver superior firepower and mobility, making it one of the best battle tanks in the world.

The Abrams M1A2 is a combat proven main battle tank developed by General Dynamics Land Systems, primarily for the US Army.
