Airmen assigned to the 23d Operations Support Squadron climb down stairs of a digital airport surveillance radar tower Aug. 27, 2020, at Moody Air Force Base, Georgia. The DASR identifies aircraft and transmits their location to radar approach control, which uses the radar to separate air traffic. RAWS technicians routinely inspect the DASR using test equipment to check signal levels, power supplies and functionality. (U.S. Air Force photo by Senior Airman Hayden Legg)
