Were Jeeps created for use in World War 2?

The Jeep was created just before the US got into the war, a design of the Willys Auto Company. It was actually a quarter-ton truck, according to the army specifications calling for designs. The Willys design exceeded all requirements the army had set forth. It was phenomenal. But the Army was concerned that Willys, a small company, would not be able to build enough of them to meet the army's needs. The Army forced Willys to allow Ford and General Motors to build the vehicles. The army's contract with those giants specified they were responsible for defective parts. Tight-fisted Henry Ford was so worried that he might get stuck having to replace parts of jeeps built by GM that all Ford-built jeeps had their parts stamped with a capital "F". As a sop, the Army let Willys build a type of trailer to be towed behind jeeps. Willys, unsurprisingly, went out of business right after the war, and the rights to the design wound up with American Motors. AMC lasted a couple of more decades, but all that survives now is the Jeep.
