Heavy equipment and pavement technicians from the 28th Civil Engineer Squadron use a concrete saw to cut through a curb during minor repairs in front of the 28th Bomb Wing Headquarters building on Ellsworth Air Force Base, S.D., June 27, 2013. The saw uses water to cool the blade during operation to prevent overheating, allowing for a precise cut. (U.S. Air Force photo by Senior Airman Kate Maurer/Released)
