M38A1 Jeep was manufactured from 1952 until 1971! They were in use by the US Army from the time of the Korean War until at least the 1990s and maybe beyond. Over 100,000 were manufactured for military and civilian use and certainly tens of thousands are still on the road all over the world. They were used by the US Army in the Korean War and Vietnam War. They could be armed with any number of small arms including every machine gun used by the US Army, recoilless rifles and even the atomic Davy Crockett.
