Airman 1st Class Shawn Mercer, 92nd Civil Engineer Squadron firefighter, runs with a fire hose May 25, 2016, at Fairchild Air Force Base, Wash. “I learned everything about shooting water from the trucks to being able to protect myself from fire,” Mercer said. “What we learn in technical school doesn’t always apply to where we are, so on the job training is important.” (U.S. Air Force photo/Airman 1st Class Taylor Shelton)
