with rotary-wing aircraft such as the CH-47/MH-47 and CH-53. The proposed ambulance variant was to be air-droppable by C-5 and C-17 fixed-wing aircraft. The JLTV can be prepared in 30 minutes for transport by aircraft, Maritime Prepositioning Force ships or rail. This is aided by an adjustable-height suspension. Versions The JLTV family and its nomenclature evolved throughout the development process and to date the U.S. Army has allocated M designations to four individual JLTV configurations. In JLTV's Initial Capability Document, there were four payload options, this later reduced to three, Payload Categories A, B, and C. By the time Capability Development Document version 3.3 was published at the conclusion of JLTV's Technology Development (TD) phase, payload options had been reduced to only two and payload verbiage had been dropped, replaced by reference to variants. From that point on two stated variants were required, the Combat Tactical Vehicle (CTV) and Combat Support Vehicle (CSV). The CTV configuration replaced the previous Category A and Category B configurations and was a 4-seat vehicle with a 3,500-pound payload. The CSV replaced the previous Category C configuration and was a 2-seat vehicle with a 5,100-pound payload. The JLTV family now consists of three base vehicle platforms, Utility (JLTV-UTL), Close Combat Weapons Carrier (JLTV-CCWC) and General Purpose (JLTV-GP). The Utility base vehicle platform is a two-door configuration, the General Purpose and Close Combat Weapons Carrier base vehicle platforms are a four-door configuration. Standard U.S. military M-designators are applied base vehicle platforms when outfitted to a specific Mission Package Configuration. These currently are: M1278 Heavy Guns Carrier - General Purpose vehicle platform in Heavy Guns Carrier Mission Package Configuration (JLTV-HGC) M1279 Utility - Utility (JLTV-UTL) base vehicle platform in Utility Mission Package Configuration M1280 General Purpose - General Purpose (JLTV-GP) base vehicle platform in General Purpose Mission Package Configuration M1281 Close Combat Weapons Carrier - Close Combat Weapons Carrier (JLTV-CCWC) base vehicle platform in Close Combat Weapons Carrier Mission Package Configuration There is also a companion trailer (JLTV-T), which is towable by all JLTV variants. L-ATV specific versions Oshkosh showcased for the first time the L-ATV Ambulance at the Association of the United States Army (AUSA) Global Force Symposium in Huntsville, Alabama, from 26 to 28 March 2019. The L-ATV Ambulance is based on the utility configuration base platform and the rear can hold 4 litters or up to 8 seated patients or a combination of the
