20th MDOS changes command
U.S. Air Force Lt. Col. Beth Dion, 20th Medical Operations Squadron commander, takes the 20th MDOS guidon from Col. Curt Prichard, 20th Medical Group commander, during a change of command ceremony at Shaw Air Force Base, S.C., June 30, 2014. Lt. Col. Colleen Frohling, the previous 20th MDOS commander, relinquished command to Dion. As a tradition dated back to the 18th century, the guidon is passed to the individual who is assuming command.
