A Ranger Assessment Course student climbs down a rope ladder during the obstacle course phase of RAC near Schofield Barracks, Oahu, Hawaii, May 20, 2019. The purpose of the 19-day course is to prepare, assess and evaluate Air Force candidates for Army Ranger School. The Airmen who pass the RAC gain more than a ticket into Ranger School and knowledge on Army tactics – they learn to lead. (U.S. Air Force photo by Staff Sgt. Hailey Haux)
