Tactical trucks are trucks that can travel where the conventional commercial trucks are immobilized by adverse terrain conditions and, for military use, must be able to withstand misuse, abuse, and neglect, yet still perform their mission.
The eight-by-eight configuration evolved from the mobility requirements. Swimming capability, with payload, is a new requirement met by the trucks, 2-1/2 Ton, 8×8, XM410E1 and 5 Ton, 8×8 XM656.
Curtailment of military personnel has resulted in the availability of less maintenance and supply support. Consequently, these new 8×8′s have been designed for a minimum of maintenance by using very durable components, sealed units, and lubed-for-life-bearings.
