Air Force Chief of Staff Gen. Mark A. Welsh III celebrated the Air Force Reserves 67th birthday by hosting a cake cutting ceremony in the Pentagon, April 6, 2015, Washington, D.C. Also on hand for the ceremony were Vice Chief of Staff Gen. Larry Spencer, Chief of the Air Force Reserves Lt. Gen. James Jackson, and the junior most ranking member of Reserve Affairs (RA) staff, Staff Sgt. Ivanka Vrechkov, who is the Non-Commissioned Officer in Charge of Policy Integration for RA. The reserves were established on April 14, 1948 by President Harry S. Truman, seven months after the active duty Air Force was established as a separate service. Originally the reserves were a standby force for use in wartime and national emergencies. The Air Force Reserves became a Major Command (MAJCOM) in 1973 and began working side-by-side with their active duty counterparts. The reserves also perform unique missions such as pararescue and weather reconnaissance. (U.S.Air Force photo/Jim Varhegyi)
