The Oshkosh M1070 is a U.S. Army tank transporter tractor unit. The primary purpose of this combination for the U.S. Army is the transport of the M1 Abrams tank.

They come in A0, A1, and M1300 configurations. The M1070 is coupled to a DRS Technologies M1000 semi-trailer. The M1300 is a U.S. Army Europe-specific derivative designed to be road legal within Europe and operates with a different trailer.[7] They replaced the earlier Oshkosh M911 tractor unit and M747 semi-trailer.

The M1070 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.

Export sales of A0 and A1[8][9] variants have been made, and derivatives of the M1070 have been produced or are available, these including the M1070F[10] and the Global HET.[4]
