Jamaal Muhammad, Air Advisor Academy instructor, dressed as an opposing force member, fires an Airsoft rifle at students from a roof top Feb. 1, 2013, on the ranges at Joint Base McGuire-Dix-Lakehurst, N.J., as part of their field training exercise. The use of Airsoft weapons allows the students and the opposing force to fire and return fire, adding to the effect and realism of the training. Muhammad is a Warminster, Pa., native.
