The Logistics Vehicle System (LVS), nicknamed by U.S. Marines as "Dragon Wagon", is a modular assortment of eight-wheel drive all-terrain vehicle unit combinations used by the United States Marine Corps.
The LVS was fielded in 1985 as the Marine Corps heavy tactical vehicle system.
The United States Army does not use the LVS, it uses the Heavy Expanded Mobility Tactical Truck (HEMTT).
The LVS also steers through both standard wheel pivoting (as on a typical automobile) and hydraulic yaw steering (by articulating the Front Power Unit against the Rear Body Unit).
When describing a truck it is remarked by the combination of both units, for example, an MK48 FPU attached to an MK18 RBU is called a "48/18".
