Airmen from the 820th Base Defense Group ambush a building during a tactical demonstration, March 27, 2017, at Moody Air Force Base, Ga. The demonstration was part of the 820th BDG anniversary, which commemorated 20 years since the activation of the 820th BDG and allowed guests to reminisce on their history, honor those they’ve lost, and witness a tactical demonstration.
