The compact military jeep continued to be used in the Korean and Vietnam Wars. In Korea, it was mostly deployed in the form of the MB, as well as the M38 and M38A1 (introduced in 1952 and 1953), its direct descendants. In Vietnam, the most used jeep was the then newly designed Ford M151, which featured such state-of-the-art technologies as a unibody construction and all-around independent suspension with coil-springs. The M151 jeep remained in U.S. military service into the 1990s, and many other countries still use small, jeep-like vehicles in their militaries.
