Col. Danielle Willis, 93d Air Ground Operations Wing commander, introduces the 820th Base Defense Group to its new commander, Col. Derrick Weyand, June 16, 2020 at Moody Air Force Base, Ga. The 820th BDG provides rapidly deployable, fully integrated, highly specialized forces for active internal and external base defense. Because of the COVID-19 pandemic, this ceremony deviated from tradition by limiting the number of guests and by symbolically moving the guidon from the old commander to the new commander, instead of passing it.
