M-16 Multiple Gun Motor Carriage, Halftrack

The Multiple Gun Motor Carriage (MGMC), Halftrack, M16 was based on the reliable M3 Halftrack chassis. The M16 carried the Quad-50 antiaircraft machine guns, consisting of four M2 HB .50 cal. machine guns in the electrically powered M45 turret. The rear box side armor panels had a hinged upper section, with a centered notch to allow the guns to fire horizontally when the armor was raised.

A total of 2,877 M16 Halftracks were produced in 1943-1944. As noted on the Quad-50 antiaircraft machine gun page, some units created their own "M16B" by bolting Quad-50 mounts taken from trailers to halftracks.

The 9.5 ton vehicle was powered by a White 160AX 6 cyl. 128 hp gasoline engine that moved it at up to 40mph on the road. They were used in World War II and the Korean War for air defense and infantry support. It was superceded by the M-19A1 Twin 40mm Gun Carriage and the M42 gun carriage (Duster).
