M1A2 Abrams Main Battle Tank

The M1 Abrams is an American third-generation main battle tank. The M1 Abrams entered U.S. service in 1980 and is the principal main battle tank of the United States Army and Marine Corps, and the armies of Egypt, Kuwait, Saudi Arabia, Australia and Iraq.

Three main versions of the M1 Abrams have been deployed, the M1, M1A1, and M1A2. In 2000, costs for the tank were upwards of US$5 million a vehicle.
The gas turbine propulsion system has proven reliable in practice and combat, but its high fuel consumption is a serious logistic issue. (Starting the turbine alone consumes nearly 10 US gallons of fuel).

The engine burns more than 1.67 US gallons per mile (60 US gallons (230 L) per hour) when traveling cross-country and 10 US gallons (38 L) per hour when idle.
The United States Army and United States Marine Corps have received over 8,100 M1, M1A1 and M1A2 tanks combined.
