Conceived for modern armored ground warfare , it is one of the heaviest tanks in service at nearly 73.6 short tons (66.8 metric tons ).
It is the main powerplant of the M1 Abrams series of tanks. The engine was originally designed and produced by the Lycoming Turbine Engine Division in the Stratford Army Engine Plant. In 1995, production was moved to the Anniston Army Depot in Anniston, Alabama, after the Stratford Army Engine Plant was shut down. [1]

The M1074 Joint Assault Bridge System (JAB, JABS) is an American armored military engineering vehicle based on the Abrams M1A1 main battle tank chassis.

The 72-ton, 40-foot-long (12 m) vehicles are based on the M1 Abrams with a 1,500 horsepower engine, but fitted with only a .50 cal machine gun and a front-mounted 15-foot-wide (4.6 m) plow, supported by metallic skis that glide on the dirt and armed with nearly 7,000 pounds (3,200 kg) of explosives.
The M1 can be equipped with mine plow and mine roller attachments if needed. The M1 chassis also serves as a basis for the Grizzly combat engineering vehicle and the M104 Wolverine heavy assault bridge. Over 8,800 M1 and M1A1 tanks have been produced at a cost of US$2.35–$4.30 million per unit, depending on the variant.
The primary purpose of this combination for the U.S. Army is the transport of the M1 Abrams tank. They come in A0, A1, and M1300 configurations. The M1070 is coupled to a DRS Technologies M1000 semi-trailer. The M1300 is a U.S. Army Europe-specific derivative designed to be road legal within Europe and operates with a different trailer. [7]
