Master Sgt. Richard MacNeal, from the 201st RED HORSE Det. 1, runs to perform a lock down after hearing rifle shots during a major accident response exercise involving an active shooter and mass causalities held at Horsham Air Guard Station, Pa., May 13, 2016. For the recent MARE, planners integrated force protection measures; reaction and response; self-aid and buddy care; and interaction with outside agencies along with the active-shooter element.
