The Oshkosh M1070 is a U.S. Army tractor unit. Defined as a Heavy Equipment Transporter, it was produced in A0, A1, and M1300 configurations, replacing the earlier Oshkosh M911 tractor unit.
The M1070’s primary role in the U.S. Army is as a tank transporter, hauling the M1 Abrams tank on a DRS Technologies M1000 semi-trailer as the Heavy Equipment Transport System (HETS). It is also used as a prime mover to transport, deploy, and evacuate armored personnel carriers, self-propelled artillery, armored bulldozers and other heavy vehicles and equipment of all types. The M1300 is a U.S. Army Europe-specific derivative designed to be road legal within Europe and operates with a different trailer.
Export sales of A0 and A1 variants have been made, and derivatives of the M1070 have been produced or are available, these including the M1070F and the Global HET.
