A few weeks before Pearl Harbor, the highest ranking officer in the Armed Forces, General George C. Marshall, described as our main contribution to modern war a new, small, bouncy army vehicle with the official designation of truck, quarter-ton, four-by-lour, but better known to practically everyone, then and now, as the jeep.
No one is certain exactly where the name “jeep” came from. The most widely accepted theory is that it originated in the pronunciation of the army designation G. P., meaning “general purpose,” but at one time or another it has been used to refer to an experimental railroad engine, a three-ton tractor, an autogyro, and a careless soda jerk. The question is further confused by the fact that in the prewar army, especially in the Armored Force, the quarter-ton four-by-four was called not a “jeep” but a “peep,” the former term being reserved for a larger command-and-reconnaissance car.
