YOUNGSTOWN AIR RESERVE STATION, Ohio -- Members of the U.S. Air Force Reserve's 910th Civil Engineer Fire Department conduct a simulated aircraft fire demonstration as German reserve officer Lt. Col. Patrick Hofmann looks on at the wing's fire pit June 17. Colonel Hofmann, a public affairs officer assigned to the German Joint Supprt Service, visited the Youngstown Air Reserve Station along with Lt. Col Stefan Bernreider, a judge advocate officer assigned to the German Air Force Reserve , June 12-26, as part of the Department of Defense Reserve Officers Exchange Program. The primary purpose of the exchange program is to provide National Guard and Reserve officers training associated with mobilization duties while enhancing their ability to work and communicate with the military individuals of the host nation. Reserve officers who participate in the exchange program receive valuable training, which they are able to share with their home units. They gain an appreciation of allied Reserve forces, which facilitates an effective working relationship with those forces upon mobilization. The Office of the Assistant Secretary of Defense (Reserve Affairs) oversees this program since its inception in 1985. U.S. Air Force photo by Master Sgt. Bob Barko Jr.
