Tanks in World War I
The continued need for four men to drive the tank was solved with the Mark V which used Wilson's epicyclic gearing in 1918. Also in 1918 the French produced the Renault FT, the result of a co-operation between Estienne and Louis Renault. As mentioned before, it had the innovative turret position, and was operated by two men. At just 8 tons it was half the weight of the Medium A "Whippet" but the version with the cannon had more firepower. It was conceived for mass production, and the FT became the most produced tank of World War I by a wide margin, with over 3,000 delivered to the French Army. Large numbers were used by the Americans and several were also lent to the British.
Oshkosh M911
In the second half of the 1970s, the US Army procured 1,000 of the heavy-haul truck - together with the four-axle M747 semitrailer - for road transportation of Main battle tanks
and other heavy loads. A tank often carried by the Oshkosh M911 was the M47 Patton. The Oshkosh M911 was also used with the US Army units stationed in Europe.
The Oshkosh M911 has a crew of 3, weighs 18.2 tons, and has a payload capacity of 68.95 tons. The Oshkosh M911 has a turbocharged 12-liter Diesel V-8 engine that produces 435 horsepower.
