Airmen from the United States and Colombian Air Forces prepare a flag for display during Exercise Green Flag East at Barksdale Air Force Base, La., Aug. 15, 2016. Green Flag East provides pilots with simulated scenarios to train in a high-threat environment, and affords maintenance and support personnel an increased tempo in generating fully mission-capable combat aircraft.
