The M718 (M151A1) and M718A1 (M151A2) 1/4 ton frontline ambulance trucks are designed to carry ambulatory and litter patients. The cargo area of the M718 and M718A1 vehicles are longer and higher to accommodate the litters and patients.
The M718 and M718A1 series is modified from the base vehicle in the following ways.
In Vietnam many M718s were used for general base transport or ambulatory (walking wounded) troops. With the mounts, rails and brackets removed. Thus providing a rear sitting area for 4 personnel, along with the 2 front seats.
