The Medium Tank M1921 was a medium tank built in the United States in the inter-war period. In design, it was similar to earlier World War I era tanks. United States Army engineers worked on the design of the tank, with some influence from British designs of the period, and from the earlier war experience. One example was produced. The tank was an early example of a turreted US tank, less usual at the time, with the turret housing the main gun, with the tank also possessing two machine guns for defense.[1]
