Col. Patrick Mordente (left), 386th Air Expeditionary Wing commander, passes the 387th Air Expeditionary Group guidon to Col. Tal Metzgar, the new 387th AEG commander, during a change-of-command ceremony at an undisclosed air base here July 13, 2010. Colonel Metzgar assumed command after Col. Randy Davis relinquished command. Passing the guidon is a tradition used to symbolize the transfer of leadership from one commander to another. (U.S. Air Force photo by Senior Airman Laura Turner)
