king of the main battle tank M1 Abrams.
The m1 Abrams is a third generation main battle tank. Abrams is designed by American defense industry general dynamics land system, which was formerly named Chrysler defense. The first model designed between 1972 to 1975. The prime manufacturer of this tank is lima army tank plant, since 1980. The m1 Abrams entered service in 1980 as the main battle tank of the united states army. It is one of the most battle tested tank in modern era.
General characteristic
M1 Abram has a gun forward length 9.77 meter, and hull length 7.93 meter. It has a width of 3.66 meter, and height 2.44 meter. The tank is operated by 4 crew and those are commander, gunner, loader and driver. The latest version m1a2 SEP V3 has a weight of 73.6 short ton, which makes it one of the heaviest tank in service. The tank has elevation of minus 10 degree to plus 20 degree, and traverse of 360 degree in 9 second. It has a ground clearance of 0.43 meter.
Armor
Abram tank is made of full body composite armor. It has depleted uranium inserts in hull and turret, with improved chobham armor and additions of arat era slat armor. The tank turret is fitted with two six barreled M250 smoke grenade launcher, with one on each side. The grenade airburst and create a thick smoke that blocks both visual and thermal imaging. The tank has a halon firefighting system to automatically extinguish fires in the crew compartment. The crew compartment also contain small hand held fire extinguishers.

These three components are determined using a laser rangefinder, crosswind sensor, a pendulum static cant sensor, data concerning performance and flight characteristics of each specific type of round, tank-specific boresight alignment data, ammunition temperature, air temperature, barometric pressure, a muzzle reference system that determines and compensates for barrel drop at the muzzle due to gravitational pull and barrel heating due to firing or sunlight, and target speed determined by tracking rate tachometers in the Gunner's or Commander's Controls Handles.
