SCHRIEVER AIR FORCE BASE, Colo. -- Maj. Gen. (Retired) Frank Casserino, former 7th Space Operations Squadron commander, speaks at the 7 SOPS 25th Anniversary celebration in downtown Colorado Springs, Aug. 4th, 2018. In 1993, 7 SOPS was activated, setting the stage for Reserve Citizen Airmen to work alongside their active duty partners in the space program. The 310th Space Group, now the 310th Space Wing, evolved from 7 SOPS and remains the only space wing in the Air Force Reserve today. (U.S. Air Force video/Staff Sgt. Laura Turner) More
