A CH-47 Chinook lifts off after dropping off Airmen during a recent two-day exercise at Duke Field Fla. Hurlburt Field Airmen were also dropped into 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)
