Six Ton Tank M1917

The M1917 was the United States' first mass-produced tank, entering production shortly before the end of World War I. It was a license-built near-copy of the French Renault FT, and was intended to arm the American Expeditionary Forces in France, but American manufacturers failed to produce any in time to take part in the War. Of the 4,440 ordered, about 950 were eventually completed. They remained in service throughout the 1920s but did not take part in any combat, and were phased out during the 1930s.
