Excuse Me, Sir
A Marine with Combat Logistics Battalion 31, 31st Marine Expeditionary Unit, detains a roleplaying aggressor during a mass casualty evacuation drill at Central Training Area in Okinawa, Japan, Dec. 13, 2013. The drill was part of the 31st MEU's pre-deployment training package which refreshes the unit's subordinate commands in a variety of operational capabilities. The 31st MEU is the Marine Corps' force in readiness and is the only continually forward-deployed MEU.
