MARINE CORPS BASE CAMP PENDLETON, Calif. - Corporal Ben Marcear, radio chief, Tango Battery, 5th Battalion, 11th Marine Regiment, and a native of Richland, Wash., provides gate security during a training exercise at the Mobile Immersion Trainer here, Nov. 14, 2013. The MIT is similar to the Infantry Immersion Trainer and trains Marines to operate under stressful conditions. Throughout the morning, the battery simulated operating out of a base and posted security while mock insurgents attempted to breach the area and formed riots. The artillerymen later conducted a logistics patrol and recovered a broken vehicle, countered an improvised explosive device and repelled enemy role-players during an ambush. The battery is slated to continue predeployment training before deploying to Afghanistan this winter.
