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.

[1] Nicknamed the "Meat Chopper",[2] the M16 was famous for its effectiveness against low-flying aircraft and infantry, making it extremely popular with soldiers.

It could reach a top speed of 41.7 mph (67.1 km/h) and a range of 175 miles (282 km) and a power to weight ratio of 15.8 horsepower per tonne.

[6] This prototype was originally designated as the T61 MGMC, but after trials at Aberdeen it was accepted as the M16 multiple gun motor carriage.

[2] The M16 saw service with U.S. forces in the Italian Campaign, and Operation Overlord, the Battle of Arracourt, and the Ardennes Offensive in northern Europe.

[6] As aircraft became more advanced over the M16's lifetime, its role as a mobile anti-aircraft weapon became limited, and the newer M19 MGMC was more heavily-armed with more powerful and longer-range guns.

[b] In late 1951, it was declared as "limited standard" and largely taken out of service from the U.S. Army in Korea, although a few examples served until the end of the war.
