JOINT BASE BALAD, Iraq -- Airman 1st Class Greg Hansen drives a sweeper on the flightline here as an MQ-9 Reaper is towed along a taxiway Aug. 16. Sweeping the taxiways prevents aircraft from sucking up foreign object debris, which can cause significant damage to aircraft. Airmen Hansen, a heating, ventilation and air conditioning technician with the 332nd Expeditionary Civil Engineer Squadron here, is deployed from Cannon Air Force Base, N.M. His hometown is Clackamass, Ore. (U.S. Air Force photo/Airman 1st Class Jason Epley)
