The Willys MB and the Ford GPW, both formally called the U.S. Army Truck, ¼-ton, 4x4, Command Reconnaissance and commonly known as Jeep or JEEP, were highly successful light military utility vehicles built in large numbers to a standardized design from 1941 to 1945 for the Allied Forces in World War II. The Jeep became the primary light wheeled transport vehicle of the United States military and its allies during the war and in the postwar period, and President Eisenhower called it one of three decisive weapons the U.S. had during World War II. It was also the world’s first mass-produced four-wheel-drive car, manufactured in six-figure numbers. About 650,000 units were built, making up a quarter of the total U.S. non-combat motor vehicles produced during the war, and, together with the Dodge WC Series, almost two-thirds of the 988,000 light vehicle class produced, with those two types outnumbering others in that class by almost two to one. Large numbers of Jeeps were also provided to U.S. allies, including Russia.
