T7 Combat Car [SEP] manufacturer
ordered that work continue on designing a convertible tank. Designed and built at the Rock Island Arsenal between 1937 and 1938, the T7 Combat Car was based on the M1 Combat Car but with an extended chassis and a convertible suspension – the ability to travel using wheels or tracks. Theoretically, it was more versatile than a conventional tank, having the ability to move with and without tracks on roads, much like the Christie designed tanks. The main gun of the project was traditional – one .50 cal (12.7 mm)
the heavy machine gun was determined insufficient for the role. The ongoing war in Europe at the time proved that, in order for a vehicle to be successful, it needed a proper cannon. In October 1939, despite its potential, the Mechanized Cavalry Board recommended further development and test of the T7 Combat Car program, and all other such convertible vehicles, be canceled. Thus ended the last wheel-tracked combat vehicle development for the U.S. Army.
