The Logistic Vehicle System Replacement (LVSR) is a family of vehicles, based on a common 5-axle ten-wheel drive 10x10 chassis, that vary in individual configuration by mission requirements. The LVSR was designed and is manufactured by Oshkosh Defense. LVSR is a purpose-designed military vehicle and there are currently three variants in service, a cargo, a wrecker and a tractor truck.

The first LVSRs were ordered in 2006. The LVSR is the U.S. Marines’ equivalent of the U.S. Army’s Oshkosh Heavy Expanded Mobility Tactical Truck (HEMTT) and Oshkosh Palletized Load System (PLS). The Marines do not use the HEMTT or PLS and the Army does not use the LVSR, but both services use a common trailer (M1076) with all three truck types.

The predecessor of the LVSR, the MK48 Logistics Vehicle System (LVS), had entered service with the US Marine Corps (USMC) from 1985 and in the late 1990s a project to replace the LVS was started.

As a precursor to a formal LVS replacement programme a number of manufacturers co-operated with the USMC to build and evaluate an Advanced Technology Demonstrator (ATD). The ATD was built during 1998 at the Nevada Automotive Test Centre (NATC). LVS Modification Demonstrators (LVS-MDs) were also built, these integrating commercially proven automotive components and technologies.

In April 2001, Logistics Management Institute (LMI) completed their final report for the 'Analysis of Alternatives (AoA) for the USMC Logistics Vehicle System Replacement (LVSR), concluding the best option was to rebuy a vehicle similar to the technology demonstrator. Five alternative options had been considered, these were: Inspect and Replace Only As Necessary (IROAN) for the LVS; rebuild the LVS; re-manufacture the LVS to a higher standard; rebuy a vehicle similar to the technology demonstrator; research and develop an entirely new vehicle. Around this time it was suggested that 2,000-3,000 vehicles might be required, although throughout the program numbers would fluctuate.
