Role
: Tank Destroyer

## [General information](/md/mtc/vehicles/m3-gmc.md#general-information)

Description
: The **M3 GMC** (Gun Motor Carriage) is a Tank Destroyer consisting of the **75 mm M1897A4** (a modernized French 75) mounted on the chassis of the [M3 half-track](/md/mtc/vehicles/m3a1.md). It was fielded in 1942 as an early U.S. tank destroyer before the [M10](/md/mtc/vehicles/m10-wolverine.md) and [M18](/md/mtc/vehicles/m18-hellcat.md) entered service. Weighing 9.1 tonnes, it is crewed by four — driver, gunner, commander, and loader — and is tracked. The **White 160AX** engine produces 148 horsepower for 16.3 hp/t and a top speed of 76 km/h.
The only primary weapon is the **75 mm M1897A4** with HE and AP; there is no coaxial or anti-aircraft machine gun. The gun has limited traverse (6 deg/s horizontal) and a 1x telescope with no rangefinder. Light armour and an open fighting compartment keep weight down but expose the crew.
