The Willys MB and the Ford GPW, both formally called the U.S. Army Truck, 1⁄4-ton, 4×4, Command Reconnaissance, commonly known as the Willys Jeep, Jeep, or jeep, and sometimes referred to as G503, were highly successful American off-road capable light military utility vehicles built in large numbers to a standardized design for the United States and other Allied forces in World War II from 1941 to 1945.
The jeep became the primary light wheeled transport vehicle of the United States military and its allies, with President Eisenhower once calling it "one of three decisive weapons the U.S. had during WWII."
Co-designed by Karl Probst and Delmar Gerle "Barney" Roos, the Willys Jeep remains one of the most iconic battlefield vehicles of our time.
