Medium Tactical Vehicle Replacement
From Wikipedia, the free encyclopedia
Medium Tactical Vehicle Replacement (MTVR) or 7-Ton, is a six-wheel drive all-terrain vehicle used by the United States Marine Corps and United States Navy.
It is designed to replace the old M900 series of tactical trucks, and was first fielded in 1998, after the contract was awarded to Oshkosh Truck Corporation. The MTVR comes in several variants, for a wide spectrum of tasks. It offers a major improvement in offroad capability with an advanced suspension, a condition adaptable Central Tire Inflation System (CTIS) and a potent engine/drivetrain combination.
The MTVR is more commonly referred to as a '7-Ton' under the misconception this denotes the vehicles weight or total cargo capacity. In fact, it is so called because its maximum payload capacity for specific offroad conditions is 7.1 tons. The MTVR's maximum payload is 15 tons onroad. The MTVR is the Marine Corps prime mover for the M777 howitzer, fuel and water assets, troops and a wide variety of equipment. Its wide versatility and offroad capability make the MTVR an integral part of the Marine Corps logistical backbone.
