It has five cargo trucks, a fuel servicing truck variant, two tractor variants, a load handling system variant, a common bridge transporter variant and a recovery vehicle with cranes and winches. Oshkosh has a total of 11 HEMTT variants in six configurations.

The second modification contract designated the names of the HEMTT A2 vehicles as HEMTT A4s. In February 2008 the first modification contract of the HEMTT A2s was placed by the US Army. The vehicles cleared performance and durability tests over the following 18 months. In 2005 Oshkosh Corporation started developing next-generation HEMTT A3 vehicles after receiving a grant from the US Department of Defense. After the R3 programme the vehicles received the designation R1 on their model numbers. The programme reduced the turnaround to 100 days including shipping time and became a great success. In December 2002 the R3 (recap, repair and return) programme was developed by the US Army and Oshkosh to increase the turnaround of HEMTTs. By 2003 about 621 trucks were contracted for recapitalisation. Under the scheme new and recapitalised vehicles were provided to many high-priority units. In 2001 the HEMTT Recapitalisation Program was established by Oshkosh and the US Army.

After 1991 the performance of the vehicles started to deteriorate. Introduced in 1985, the HEMTTs are the backbone of the US Army's logistics fleet. The huge payload capacity and off-road capabilities make it a key logistics player. The key mission of the HEMTT is to offer heavy transport capabilities for resupply of combat vehicles and weapon systems. More than 13,000 HEMTTs are in service today.

Nicknamed “Dragon Wagon,” the HEMTT first went into service with the Army in 1985, replacing the M520 Goer trucks. The Heavy Expanded Mobility Transport Truck is an 8 x 8 diesel off-road tactical truck used by the US Army.
