It has a targeting range of up to 4,800 m and can engage low altitude enemy threats at up to 3,800 m. The missile itself weighs 22 lb (10.1 kg), while the missile with its launch tube and integral sight, fitted with a gripstock and Identification friend or foe (IFF) antenna, weighs approximately 34 lb (15.2 kg). A helicopter launched version exists called Air-to-Air Stinger (ATAS). The missile is also capable of being deployed from a Humvee Stinger rack, and can be used by airborne troops. The FIM-92B missile can also be fired from the M-1097 Avenger and the M6 Linebacker. Light to carry and easy to operate, the FIM-92 Stinger is a passive surface-to-air missile that can be shoulder-fired by a single operator (although standard military procedure calls for two operators, team chief and gunner).
