Truck, Utility, ¼-Ton, 4×4, M151 was the last generation of the traditional "jeep" light utility vehicles fielded by the United States armed forces. It was developed by the Ford Motor Company under a 1951 contract to replace the U.S. Army's fleet of Willys M38 jeeps, which in turn were the successors to the original Bantam-based Willys MB and Ford GP jeeps of World War II. The M151 strongly resembles its predecessors, but is larger and based on a completely new platform. Visually, it is easily distinguished by its horizontally slotted front grille (since the classic vertical grille of the earlier jeeps was, by 1951, a trademarked aspect of the civilian Jeeps being sold by Willys). The M151 was replaced starting in 1983 by the HMMWV, but a few examples are allegedly still used by some Special Forces units today.
