United States, where his talent for logistics would be put to use in establishing the Army's primary tank training center at Camp Colt in Gettysburg, Pennsylvania. Eisenhower became the #3 leader of the new tank corps and rose to the temporary rank of lieutenant colonel in the National Army and trained tank crews at "Camp Colt"–his first command–on the grounds of "Pickett's Charge" on the American Civil War battle site. The American Army in France had Captain George S. Patton as the first officer assigned to train the crews. While tanks like the Mark V and FT were being shipped over from France and Britain for training, Eisenhower trained his units with trucks that had bolted down machine guns. Once the tanks arrived Eisenhower had to learn how to operate one first before letting his men use it. The Six Ton Tank M1917 was the U.S.'s first mass-produced tank, a license-built near-copy of the French Renault FT. The U.S. Army ordered approximately 4,440 M1917s between 1918 and 1919, receiving about 950 before canceling the contract. The initial requirement of 1,200 was decided upon then later increased to 4,400, and some sample Renault tanks, plans, and various parts were sent to the US for study. The design was to be carried out by the Ordnance Department, under the job title "Six-ton Special Tractor", and orders for the vehicles placed with private manufacturers. However, the project was beset by problems: the French specifications were in metric, and thus incompatible with American machinery; coordination between military departments, suppliers, and manufacturers was poor; bureaucratic inertia, lack of cooperation from military departments, and possible vested interests all delayed progress. The Army in France was expecting the first 300 M1917s by April 1918, but by June, production had yet to begin, which forced the US to acquire 144 Renault FTs from the French. Production of the M1917 did not begin until the autumn, and the first completed vehicles emerged in October. Two arrived in France on 20 November, nine days after the armistice with Germany, and a further eight in December. The Ford 3-Ton M1918 was one of the first light tank designs by the U.S. It was a small two-man, one-gun tank, armed with an .30 M1919 Browning machine gun and capable of a maximum speed of . Design on the 3-ton tank started in mid-1918. The 3-Ton was a two-man tank designed so that
