The United States Air Force Ranger Assessment Course is a stress-fueled battle school which develops Airmen to lead under mental, emotional, and physical strain, improving Airmen’s resiliency and coping mechanisms. Qualified Airmen from any career field can attend the course, which is held twice a year. The course has a 66-percent fail rate. <br />
