U.S. Air Force Brig. Gen. Barry Cornish, 18th Wing commander, passes the 18th Medical Group guidon to Col. James Lasswell, 18th MDG commander, during the group's change of command ceremony on Kadena Air Base, Japan, July 9, 2015. The change of command is a traditional military ceremony in which the departing commander relinquishes command to the incoming commander. The 18th Medical Group, the Air Force's largest freestanding ambulatory clinic in terms of assigned personnel, provides extensive medical, dental and support services to Kadena and other Department of Defense beneficiaries living on Okinawa. More than 70 medical and dental providers care for nearly 800 patients every day. (U.S. Air Force photo by Naoto Anazawa)
