51st MDSS Change of Command
Col. Jennifer Vecchione, 51st Fighter Wing Medical Group commander, left, receives the guidon from Col. Theodosia Montgomery, 51st Medical Support Squadron (MDSS) outgoing commander, as a symbol of Montgomery’s relinquishment of command of the MDSS at Osan Air Base, Republic of Korea, June 17, 2022. A change of command is a military tradition, which represents a formal transfer of authority and responsibility for a flight, squadron, group, wing or MAJCOM from one commanding officer to another. The passing of the guidon ensures the unit and its Airmen are never without leadership. (U.S. Air Force photo by Senior Airman Trevor Gordnier)
