One of the most famous military vehicles of World War II, the jeep originated in a prewar US Army requirement for a simple, inexpensive, and robust vehicle for basic utility chores. Its simple design proved to be adaptable to a host of military tasks including use as a scout vehicle, battlefield ambulance, communications vehicle, and staff car. The jeep was hailed as “the savior of World War II.”

The designation “GPW” breaks out as follows: “G” is “Government,” “P” represents “80-inch wheelbase reconnaissance” and “W” for “Willys” as they were the designers of the original blueprints on which the jeeps were based.
