Heavy Equipment Transporter System
The
heavy equipment transporter system (
HETS) is used to transport, deploy, and evacuate tanks and other heavy vehicles. It consists of either the M746 or the M911 truck tractor, with the M747 semitrailer. During Operations
Desert Shield and
Desert Storm the HETS vehicles were employed primarily to haul
M1 Abrams tanks. However, they demonstrated poor durability when loads exceeded 60 tons.
