Armed Services Blood Program delivers life
U.S. Air Force Staff Sgt. Joseph-Luis Kilgo, 86th Medical Squadron NCO in charge of training, pats a bag of blood at Landstuhl Regional Medical Center, Sept. 22, 2016. After the blood and plasma have been manually separated, clumped protein must be mixed back into the blood to ensure it is distributed throughout the entire unit. (U.S. Air Force photo by Staff Sgt.
