From the Background: "According to the Army, the Joint Light Tactical Vehicle (JLTV) Family of Vehicles (FoV) is an Army-led, joint-service program designed to replace a portion of each service's light tactical wheeled vehicle fleets. The JLTV FoV consists of two variants: the four-seat Combat Tactical Vehicle (CTV) and the two-seat Combat Support Vehicle (CSV). The CTV is to support the General Purpose, Heavy Gun Carrier, and Close Combat Weapon Carrier missions. The CSV is to support the Utility/Shelter Carrier mission. The JLTV is transportable by a range of lift assets, including rotary-wing aircraft. Its maneuverability enables activities across the spectrum of terrain, including urban areas, while providing inherent and supplemental armor against direct fire and improvised explosive device threats."
