The Logistics Vehicle System (LVS) is a modular assortment of eight-wheel drive all-terrain vehicle unit combinations used by the United States Marine Corps. It is nicknamed "Dragon Wagon", which is a reference to the famous M25 tank transporter.

The LVS was fielded in 1985 as the Marine Corps heavy tactical vehicle system. It was designed and manufactured by the Oshkosh Corporation. The United States Army does not use the LVS, it uses the Heavy Expanded Mobility Tactical Truck (HEMTT). The key differences between the two is the LVS's ability to interchange Front Power Units with Rear Body Units. 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). This enabled the LVS to meet the turning radius requirements of the U.S. Marines. LVS is rated to haul up to 22.5 tonnes (50,000 lb) on highways.

The Oshkosh Logistic Vehicle System Replacement (LVSR) is the replacement for the LVS and was first fielded in 2009.

The LVS is composed of a Front Power Unit (FPU) coupled to a Rear Body Unit (RBU). The FPU can be driven on its own. 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". For MK16's, which tow M870 semi-trailers, the type of trailer is added as well, i.e. "48/16/870A2".
