Operation Enduring Freedom (OEF)
U.S. Air Force Senior Airman Aleza Chan, medical lab technician, 966th Air Expeditionary Squadron, goes through the lengthy process of testing blood from donors at the blood testing section of the NATO Role 3 Hospital, Kandahar Airfield, Afghanistan, Oct. 25, 2012. Chan is part of a five-person Air Force team that runs the apheresis program at the hospital, which helps to collect blood platelets donated by members at Kandahar. The platelets are then stored and later used to help promote blood clotting in trauma patients injured in combat. The apheresis section helps to collect platelets for not only patients at Kandahar, but also for 14 other Forward Operating Bases in Afghanistan. (U.S. Air Force photo/Staff Sgt. Clay Lancaster)
