Ismael Alicea, Joint Base McGuire-Dix-Lakehurst, N.J., fire department crew chief, hydrates before he extinguishes multiple fires on a training aircraft June 10, 2011. The Joint Base MDL fire department joined forces with Reservists from the Marine Wing Support Squadron 472 successfully extinguishing fires that engulfed two engines of a mock aircraft trainer. Firefighters wear more than 60 pounds of insulated gear while battling the fires, so hydration is essential for them not to overheat. (U.S. Air Force Photo/Airman 1st Class Dennis Sloan)
