The M16 Multiple Gun Motor Carriage (MGMC for short) was an American self-propelled anti-aircraft gun from the Second World War. The first prototypes were built in 1942, and serial production continued in the period 1943-1944. In total, about 2,700-2800 copies of this vehicle were produced on the production lines, and another 650 vehicles were created by rebuilding other cars. The M16 was powered by a single engine White 160AX with a power of 128 hp . It was armed with four 12.7 mm M2HB Browning machine guns.

The M16 Multiple Gun Motor Carriage was developed at White Motor Company based on the undercarriage and hull of the M3 Half-Track Transporter. The M16 vehicle was developed to complement the in-line replacement of the M13 vehicle. Compared to its predecessor, it differed primarily in twice the firepower and slightly better off-road properties. It also used a modernized base for the main armament, designated M45. However, both vehicles - ie the M13 and M16 - used many of the same components and the M13 vehicles still in service were often rebuilt to the M16 standard. Under the designation M17, the car was also exported under the Lend-and-Lease program to the Soviet Union. The M16 vehicles took part in several campaigns of World War II, including: the battles in Italy (1943-1945), during the battles in Normandy in 1944 and in the course of subsequent battles in North-Western Europe in 1944-1945. They were also used against ground targets in the Korean War (1950-1953).
