The Oshkosh M1070 is a U.S. Army tank transporter tractor unit. In current service in A0, A1, and M1300 configurations, the M1070 is coupled to a DRS Technologies M1000 semi-trailer. The primary purpose of this combination for the U.S. Army is the transport of the M1 Abrams tank. The M1300, covered in a separate sub-section, is a U.S. Army Europe-specific derivative designed to be road legal within Europe and operates with a different trailer.
The M1070 is also used to transport, deploy, and evacuate armored personnel carriers, self-propelled artillery, armored bulldozers and other heavy vehicles and equipment of all types.
This combination replaced the earlier Oshkosh M911 tractor unit and M747 semi-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.
