M8 75mm Howitzer Motor Carriage (HMC)

The M8 Howitzer Motor Carriage (HMC) was a modification of the M5 Stuart Light Tank to mount the M2 75mm howitzer. A special turret was designed to fit the Stuart turret ring. Production records indicate that 1,778 of these self-propelled howitzers were built by Cadillac Division of General Motors in Detroit, MI during World War II (1942-1944). They were deployed to armored units in both the European and Pacific Theaters of Operations. It was superceded by the widespread deployment of the M4 Sherman tank with its 105mm main gun.

The M8 75mm Howitzer Motor Carriage carried 46 rounds of ammunition. In addition, it could tow an ammunition trailer with additional rounds.
