A U.S. Air Force firefighter assigned to the 379th Expeditionary Civil Engineering Squadron, notes the condition of a Royal Air Force member on his mass casualty incident tag during an accident response exercise on the runway at Al Udeid Air Base, Qatar, Oct. 3, 2017. The military members were taking part in a joint U.S., UK and Qatari exercise, revolving around the simulated landing gear failure on a Royal Air Force C-130J Hercules. The exercise was designed to test the 379th Air Expeditionary Wing and coalition forces post-crash emergency management plan. (U.S. Air National Guard photo by Tech. Sgt. Bradly A. Schneider/Released)
