There continues to be disinformation concerning whether or not the Army called the jeep a “general purpose” vehicle or not. Of course one has to know about military procurement in order to understand the answer. The vehicle that became known as the “jeep” was originally procured by the Quartermaster Corps at the request of the using arms (Infantry, Cavalry and Field Artillery).
In fact, evidence of this is stated in AR 850-15 as quoted by Book 120 Field Artillery, Automotive Instruction, 1941 Edition:
“Classification: General-Purpose Motor Vehicles–All wheeled vehicles adapted for general hauling purposes including general cargo, ammunition, personnel, and equipment; and for towing trailers, guns, and other wheeled equipment. Examples: Cargo trucks, dump trucks, passenger vehicles, ambulances.”
“Estimates, Design, Development, Procurement, Maintenance, Storage, and Issue: By the Quartermaster Corps, except the design and development of ambulances, which will be by the Medical Department in collaboration with the Quartermaster Corps.”
The same Book 120 also defines “truck”. Trucks are “motor-propelled vehicles designed primarily for carrying cargo or equipment. They may be used for carrying personnel or for towing purposes.” Still further it provides a chart that lists the Truck, 1/4-ton, 4×4, Ford, 1941. The chart defines ‘purpose’ for us. “The purpose will be indicated by stating the general character of the body or the use for which the vehicle is designed.& The trucks maybe for “cargo, light repair, reconnaissance, dump, tank, cargo and dump, wrecking, or pick-up.” The jeep’s ( or Geep!) purpose is reconnaissance.
