By the eve of World War II, the United States Department of War had determined it needed a -ton, cross-country reconnaissance vehicle. Although -ton four-by-fours had outperformed -ton 4x4 trucks during testing in 1938, the half-ton 4x4 trucks – both from Marmon-Herrington Ford, and the 1940 Dodge VC series – still proved too large and heavy, and insufficiently agile off-road. Anxious to have a quarter-ton truck in time for America's entry into World War II, the U.S. Army solicited proposals from domestic automobile manufacturers. Recognizing the need to create standard specifications, the Army formalized its requirements on 11 July 1940, and submitted them to 135 U.S. automotive manufacturers.
