The M5 is a fully track vehicle designed to tow the 105 mm Howitzer M2, and the 155 mm Long Tom field artillery, and carry the gun crew and ammunition. A winch and roller system allows the M5 to pull vehicles to the front or rear. Armament is a single anti-aircraft M2 Browning machine gun.
The M5 was standardized in October 1942 from the T21, a vehicle based on the tracks and suspension of the Stuart tank. International Harvester started production in 1942. Use of the M5 in the US Army ended shortly after World War II, though Japan, Austria, Yugoslavia, Lebanon and Pakistan continued to use it.
