Students with the 23rd Special Tactics Training Squadron move upstairs to clear a building during a recent two-day exercise at Duke Field Fla. Hurlburt Field Airmen were dropped to the exercise location by a 919th Special Operations Wing MC-130E Combat Talon I to begin the exercise. The exercise provided counter-insurgency tactics, land navigation and mission planning to potential Air Force combat controllers. (U.S. Air Force photo/Tech. Sgt. Cheryl Foster)
