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) (Figure 1) and the two-seat Combat Support Vehicle (CSV) (Figure 2). 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."
