As an Expanded Capacity Vehicle, the M1151 is specifically designed for use over all types of roads, as well as cross-country terrain, and in all weather conditions without sacrificing mobility, dependability or performance. The M1151 payload varies by armor configuration and fragmentation kit, ranging from 3,340 to 5,100 lb. The M1151 is air transportable and droppable, and can be sling-loaded by helicopter.

The M1151A1 provides superior protection for crew, weapons components, and ammunition. With the addition of the “B” kit, the M1151A1 provides gapless mine and ballistic protection. The additional armor and fragmentation kits are field installable and removable to provide flexibility for missions that do not require heavy protection. The vehicles are equipped with an A/C system to provide greater crew comfort.
