U.S. Army soldiers from the 377th Maintenance Company, out of Manitowoc, Wis., attach tow bars to a Humvee, in preparation for towing during Warrior Exercise 91 13-01, March 23, 2013. The exercise was planned and coordinated by the 91st Training Division (Operations), giving participating units an opportunity to rehearse military maneuvers and tactics such as base security, convoy operations, and battle reaction drills during simulated enemy attacks. The exercise provides realistic training to units to successfully meet the challenges of an extended and integrated battlefield. The joint exercise drew more than 3,500 soldiers, airmen and sailors from across the United States. (U.S. Army photo by Spc. Bryan A. Randolph, 300th Mobile Public Affairs Detachment)
