Both were passengers in a M939 series 5-ton tactical cargo truck that overturned. This report identifies (1) the extent to which accidents involving the M939 series 5-ton tactical cargo truck have occurred and (2) the results of Army studies on the truck's design and its plans to address any identified deficiencies. You also asked us to evaluate the adequacy of the Army's training program for the drivers of the M939 truck because inadequate training could be a contributing factor in accidents. This issue will be addressed in a later report. The Army classifies its vehicles on the basis of such factors as function and physical characteristics. For example, tracked vehicles (Abrams Tanks and Bradley Fighting Vehicles) are classified as Army combat vehicles; wheeled vehicles (trucks, automobiles, cycles, and buses) are classified as Army motor vehicles. Within the Army motor vehicle grouping, vehicles are further separated into tactical and non-tactical categories and within the tactical grouping, into light, medium, and heavy classifications based primarily on vehicle weight. The M939 series trucks are accounted for as part of the Army motor vehicle's medium tactical fleet. 收起
