Background
The Medium Tactical Vehicle Replacement (MTVR) cargo truck was adapted by the U.S. Marine Corps and U.S. Navy as a replacement for the M939 series of trucks that had been in use since the early 80s. It offers improved off-road capability and greater capacity than the earlier models. It is the prime mover for the USMC M777 Howitzer and is used to carry troops, cargo, fuel, and water to every corner of the battlefield.
The MTVR was first fielded in 1998 and is built by Oshkosh Industries. Deliveries are continuing, and so far some 11,000 in 12 different variants have been delivered to the US Marines, the Navy Seabees, as well as the Iraqi and Egyptian armies. The variants include 4x4 and 8x8 versions, along with the standard 6x6 configuration.
