The Oshkosh Defense Heavy Equipment Transporter HET

The Oshkosh Defense Heavy Equipment Transporter HET aka M1070, is a combination of Oshkosh Corporation M1070 tractor and M1000 System & Electronics (now DRS Sustainment Systems Inc.) semi-transporter trailer.

The original HET entered service with the US Army in 1993 using a 500hp Detroit Diesel engine. It was designed to transport 70 tonne of armoured fighting vehicles, which included the M1A1 Abrams tank or x2 Bradleys or other Combat Engineer Vehicle. Unlike a lot of transports, the HETS has an off-road capability.
