The M16 multiple gun motor carriage, also known as the M16 half-track, was an American self-propelled anti-aircraft weapon built during World War II. It was equipped with four .50 caliber (12.7 mm) M2 Browning machine guns in an M45 Quadmount. 2700 were produced by White Motor Company from May 1943 to March 1944, with 568 M13 MGMCs and 109 T10 half-tracks being converted into M16s as well.
The chassis was derived from the T1E2 chassis, an earlier version of the M13. Based on an M3 half-track chassis, it replaced the M13 MGMC half-track after early 1944. As aircraft became more advanced, the usefulness of the M16 was reduced. In the Korean War, it was relegated primarily to the ground-support role, being put out of service in the U.S. Army in 1954.[citation needed]
Nicknamed the "Meat Chopper",[1] the M16 was famous for its effectiveness against low-flying aircraft and infantry, making it extremely popular with soldiers. It was used by the United States Army, the British Commonwealth, and South Korea. A similar version of the M16, the M17, was based on the M5 half-track and exported via Lend-Lease to the Soviet Union.[citation needed]
