The surveillance of a simulated downed aircraft plays in the Emergency Operations Center during a Mass Casualty Exercise on Marine Corps Air Station Cherry Point, N.C., April 7, 2016. The exercise was designed to simulate the response if an emergency were to occur.

On years the biannual air show occurs, the training revolves around scenarios specific to that kind of event. (U.S. Marine Corps photo by Cpl.
