A member of the Goldsboro emergency medical service wheels a gurney with a simulated injured Airman during an active shooter mass casualty exercise, May 9, 2018, at Seymour Johnson Air Force Base, North Carolina. Training across the wing with the local civil authorities has been implemented so emergency responders can be ready at a moment’s notice. (U.S. Air Force photo by Airman 1st Class Miranda A. Loera)
