Barksdale Defenders run and gun for active shooter training
Master Sgt. Paul Stacey, 2nd Security Forces Squadron flight chief, helps Senior Airman Samantha Albalos, 2nd SFS entry controller, secure protective gear at Barksdale Air Force Base, La., July 18, 2016. The squadron conducted the training in teams of two, rather than their usual four-person teams, because a typical team responding to a real-world situation consists of two Airmen.
