Oshkosh Defense® HEMTT A4 M977A4 Cargo Truck

Performance to meet logistics mission demands.

The Oshkosh® Heavy Expanded Mobility Tactical Truck (HEMTT) A4 Cargo Truck is extremely durable and reliable. It has the power to traverse even the most treacherous environments and the capacity to carry supplies, equipment or ammunition wherever it needs to support mission success. An on-board crane with a 2,500 pound (1,134 kg) load capacity can load and unload even the heaviest loads, and an anti-lock braking system, traction control and air-ride suspension provide for easier negotiation over any type of terrain. The large Long-Term Armor Strategy-ready cab (LTAS) offers adequate space for crew members and is climate controlled to help assure occupant comfort and mission readiness.
