Airmen from the 820th Base Defense Group low crawl through an obstacle during an Army Air Assault School readiness assessment, Dec. 7, 2017, at Camp Blanding, Fla. The AAA readiness assessment is designed to prepare Airmen for the course curriculum as well as its physical and mental stressors. During AAA, service members are taught an array of skills associated with rotary-winged aircraft, which improves the 820th BDG’s ability to swiftly deploy and defend.
