Jonathan Mckee, riflemen serving with Fox Company, 2nd Battalion, 1st Marine Regiment, provide suppressive fire as their squad members breach a building during Military Operations on Urban Terrain training at the Infantry Immersion Trainer here, May 29, 2013. Perry, 19, from Cape Girardeau, Mo., said his favorite aspect of the immersion trainer is the realistic feeling the role players brought to the training. The role players changed their attitudes and spoke in different languages during the scenarios.
