Iwakuni City firefighters carry a casualty to an ambulance during the Mass Casualty Exercise 2016 at Marine Corps Air Station Iwakuni, Japan, March 23, 2016. Conducted in preparation for the JMSDF/MCAS Iwakuni Friendship Day 2016 Air Show, the exercise simulated a dual aircraft collision where large crowds will be expected. The JMSDF participated in the exercise to enhance bilateral cooperation with U.S. first responders, establish safety measures and maintain situational readiness. To make the exercise more realistic, first responders did not know when, where or what would happen. After evaluating last year’s exercise, more residents participated in the exercise as actors and selected as either a casualty or bystander. (U.S. Marine Corps photo by Lance Cpl.
