U.S. Air Force Joint Terminal Attack Controllers, Master Sgt. Mike Macias, 66th Weapons Squadron superintendent, and Staff Sgt. Josh Costa, 17th Special Tactics Squadron JTAC, parachute down to the desired impact point at Brownwood Regional Airport in Brownwood, Texas, Nov. 1, 2018. The airport acted as the simulated enemy territory where JTAC members jumped from a plane to mimic entering a combat environment and leave the area without being detected.
