An Airman hits a keiser sled during the Firefighter Challenge at the 28th Civil Engineer Squadron Fire Department at Ellsworth Air Force Base, S.D., Oct. 4, 2019. Hitting a keiser sled simulates trying to bust down drywall or a hard wall during a house fire. (U.S. Air Force photo by Airman Quentin K. Marx)
