The W.W. I French Renault tank first appeared on the Western Front in 1918; it had a crew of two, measured 13 feet in length and weighed 6.5 tons. The tank's 35 hp. engine moved it along at a top speed of 6 mph. The factory options were few: one turret was fashioned to accommodate a 37mm gun while the other was made for a machine gun. The American Army placed 227 of these tanks in the field; the American Renaults were differed distinctly from those commanded by the French: the American version sported an octagonal turret (as opposed to a circular one) and steel wheels (the French Army preferred wood).
In 2003 a couple of 1918 Renault tanks were found rusting away in an Afghan junk yard whereupon they were quickly whisked away for restoration and exhibition at the Fort Knox Tank Museum in Kentucky.
