Holt gas electric tank
The Holt Gas-Electric Tank was the first prototype tank built in the United States in a collaboration between the Holt Manufacturing Company (now Caterpillar Inc.) and the General Electric Company. The tank, built during 1917-1918, was the only one of its kind built, as testing proved it lacked the agility and maneuverability required. The crew number is often given as six, on the assumption there would be two machine gunners, a gunner and loader for the main gun, a driver and a commander.
