This was the first appearance of the round fender Jeep that would eventually become the civilian CJ5. The M38A1 was quite different that the CJ5 having a stronger chassis and reversed front spring shackles in addition to the military accessories such as standardized GI instruments and a 24 volt electrical system. The M38A1 lasted quite awhile in military service. Even after it was replaced by the high tech Ford M151 they could be seen in OD green as late as the 1970's.
From 1953 to 1963 they made an ambulance version of the M38A1 called the M170. Production numbers were 6,500 units. This later became the civilian CJ6
