Jeep is an automobile marque (and registered trademark) of Chrysler. It is the oldest off-road vehicle (also sport utility vehicle – SUV) brand, with Land Rover coming in second. The original vehicle which first appeared as the prototype Bantam BRC became the primary light 4-wheel-drive vehicle of the US Army and allies during the World War II and postwar period. Many vehicles serving similar military and civilian roles have since been created by many nations.
