The Caiman is an armored vehicle with a V-hull design based on the Family of Medium Tactical Vehicles (FMTV) and Low Signature Armored Cab (LSAC), initially developed by Stewart & Stevenson. Stewart & Stevenson was later acquired in 2005 by Armor Holdings, which developed the Caiman from the FMTV and LSAC designs. Armor Holdings also owned O'Gara-Hess & Eisenhardt and Integrated Textile Systems at the time.
