A Master Driver with the 174th Infantry Brigade drives a mine-resistant, ambush-protected (MRAP) vehicle through closely-spaced shipping containers at the revamped drivers training course July 13, 2012, at Joint Base McGuire-Dix-Lakehurst, N.J. The shipping containers are meant to simulate an urban environment, where buildings and narrow streets require high awareness of the MRAP's size and turning ability.
