Heavy Equipment Transport System

The current U.S. Army vehicle used in this role is an Oshkosh-built M1070 tractor unit in A0 and A1 configurations which is coupled to a DRS Technologies M1000 semi-trailer.

[2] The M1070E1 model was developed in the mid-1990s in conjunction with the U.S. Army as a possible Technology Insertion Program (TIP) for the M1070.

[2] In March 2008, Oshkosh Defense announced a contract award from the U.S. Army to begin engineering and initial production of the next-generation of HET.

Nicknamed the Dragon Wagon, the M25 was composed of a 6×6 armored tractor (M26) and 40-ton trailer (M15).

Prior to 1993, the U.S. Army employed the Commercial Heavy Equipment Transporter (C-HET), which consisted of either the M746 or the M911 truck tractor and the M747 semitrailer.
