M38A1 (1952-1971)

In 1950, the first post-war jeep, the M38 (or MC), was launched, based on the 1949 CJ-3A. In 1952 it was quickly followed by the M38A1 (or MD), featuring an all new "round-fendered" body in order to clear the also new, taller, Willys Hurricane engine. This jeep would later be developed into the CJ-5 launched in 1955. Similarly, its ambulance version, the M170 (or MDA), featuring a 20-inch wheelbase stretch, was later turned into the civilian CJ-6.
