The Willys MB, better known as the 'Jeep,' was a revolutionary light military vehicle developed for the U.S. Army. General George C. Marshall called it 'America's greatest contribution to modern warfare.' Its four-wheel drive and rugged design allowed it to traverse mud, sand, and mountains where other vehicles failed. It served as an ambulance, a scout car, a cable layer, and even a tractor. Its name is believed to have come from the military designation 'GP' (General Purpose), though some suggest it was named after a character from the Popeye cartoons. Over 640,000 were produced during the war, becoming a global symbol of American industrial might.
