The M4 High-Speed Tractor was an artillery tractor used by the US Army from 1943.

Construction

The M4 was based on the automotive components of the M2 Light Tank, with one variant designed to tow anti-aircraft guns and another for howitzers. The rear compartment carried the gun crew and other equipment and some later variants included a crane to assist with heavier projectiles.

History

The M4 was manufactured by Allis-Chalmers of Milwaukee, starting in 1942 and was in U.S. military service until approximately 1960.

Under the Mutual Defense Assistance Program, the M4 was supplied to Japan, Brazil, Yugoslavia and Pakistan after World War II ended.
