Our mascot is the 76 mm Gun Motor Carriage, a highly mobile, low silhouette, lightly armored motor carriage designed for tank destroyer use. It is of the full track-laying type using a torsion bar independent suspension, front sprocket driven. Sloping armor is used, affording good ballistic qualities.
Principle armament is a 76 mm Gun, M1A1, in an open top turret with a partial turret basket. The gun may be elevated from -10 to +20 degrees. The turret may transverse through 360 degrees. A Ring Mount, M49, for a cal. .50 machine gun, is provided on the top of the open turret for antiaircraft protection. Provision is made for carrying five cal. .30 carbines.
The A.P.C. Projectile, M62, fired in the 76mm gun, with a muzzle velocity of 2600 feet per second, will penetrate four inch face-hardened armor plate at 1000 yards.
Driver and assistant driver occupy seats in the hull, and the gunner, loader and commander in the turret. Two escape hatches are in the hull roof and one in the floor. Periscopes, M6, are provided for the driver and assistant, and a periscope, M4, with telescope, M47, for the gunner.
Power is supplied by a Continental R975 -C4 gasoline engine. Transmission is torquo-matic, with three speeds forward and one reverse.
An SCR-610 or British 19 radio is provided, as well as interphone stations.
The pilot vehicle was built by the Buick Motor Division of General Motors Corp.
