SHAW AIR FORCE BASE, S.C. --
The new M-7 Firehawk helps Airmen complete the mission by being more durable, safer, user friendly and uses one tank instead of two. The mask has more features, which include a voice enhancer and a heads up display that shows how much air is left in the tank. (U.S. Air Force photo/Airman 1st Class Tabatha L. Duarte)
