The M151 was intended to be a lightweight, high-mobility replacement for the M38A1, itself a successor to the famed World War II jeep. Dubbed the Military Utility Tactical Truck or MUTT by the military - GIs almost universally referred to the vehicle as a jeep. The series' service life spanned more than 40 years and four manufacturers, and the vehicles saw service everywhere the US GI was deployed. This volume chronicles the development and field use of the M151 series in Europe, the Middle East and, of course, there is extensive coverage of the vehicles' service in Vietnam. The photos, many previously unpublished, are augmented by seven line drawings. Illustrated with 220 photographs; 80 pages.
