The Ford 3-Ton M1918 was one of the first tank designs by the U.S. It was a small two-man, one-gun tank. It was armed with a Browning machine gun and could reach a maximum speed of 8 mph (13 km/h). The 3-Ton had a 17-US-gallon (64 l) tank that gave it a maximum range of 34 miles (55 km). Designer M Bergman
