M1 Combat Car

The M1 Combat Car was a tankette used by the U.S. Cavalry in late 1930s.

History
Under the terms of the Defense Act of 1920, tanks were restricted to infantry units. To allow U.S. Army cavalry units to be equipped with armoured fighting vehicles, the tanks developed for the cavalry were designated "combat cars". The M1 series entered service in 1937. In 1940, the Combat Car designation was dropped, and the vehicle were renamed as light tank M1A2.
