The Army will repair armored FMTVs (sustainment repair at depot) when required, as they are retrograded from theater; it will repair or divest armored legacy MTVs depending on fleet requirements and vehicle condition. Vehicles with Radian Armor Crew Kits Add-on-Armor (AoA) will have the armor removed, demilitarized and disposed. The vehicle will be returned to its standard unarmored Full Materiel Release configuration.
In approximately 2003, the first armored FMTV trucks were fitted with the field-applied (to the regular cab) Radian Armored Crew Kit (RACK) - also called the Crew Protection Kit (CPK). Protection was then upgraded and simplified by the creation of the Low Signature Armored Cab (LSAC) armor package which was applied instead of the regular cab at the factory. In 2006 the Long-Term Armor Strategy (LTAS) modular armoring solution was developed which utilizes an ?A? (Basic) protection package with ?B? kits that can mounted when additional armor is warranted.
