M3 Gun Motor Carriage is an American tank destroyer.
A variant of the M3 Half-track, the M3 Gun Motor Carriage is equipped with a 75mm M1897A5 gun. The M2 Browning machine gun is retained, but is moved further back on a pintle mount.
In Battlegroup42 its in-game name is M3 GMC. It mostly appears in the late stage of North Africa theatre as well as in Italy campaign, but a small number also appears in the Pacific theatre. Its role as a tank destroyer is later succeeded by M10 Wolverine.
