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