Lance Cpl. David Gamble acts as the opposing force hiding inside a building while a fire team of Marines clear it and search for a hostage in Central Training Area’s Combat Town in Okinawa, Japan, Nov. 6, 2015. Both sides used special effect small-arms marking system rounds to create a more realistic environment because they can see where their shots land. Gamble is from Dallas, Texas, and is a military policeman with Military Police Detachment, Combat Logistic Battalion 31, 31st Marine Expeditionary Unit. ( Marine Corps photo by Cpl.
