M-730a1 Chaparral

The Chaparral SAM system consists of an infrared heat seeking missile, a launcher with a Forward Looking Infrared (FLIR) sight, and a tracked vehicle. The defense system was designed to be used in conjunction with the shorter-ranged M163 Vulcan Air Defense System. At its core, the Chaparral system is essentially a modified version of the M548 tracked carrier mated to the M54 launch and control system containing four launch rails. The system uses the M730 series cargo carrying, self-propelled tracked vehicle "9A" variant of the M113 Armored Personnel Carrier, which can be made amphibious by adding an existing swim kit. A towed configuration is also available
