Staff Sgt. Corey Creasia, 2nd Munitions Squadron armament systems supervisor, inspects a heavy stores adaptor beam during Global Thunder 2019 at Barksdale Air Force Base, La., Oct. 31, 2018. Global Thunder is an annual U.S. Strategic Command (USSTRATCOM) exercise designed to provide training opportunities to test and validate command, control and operational procedures. The training is based on a notional scenario developed to drive execution of USSTRATCOM and component forces' ability to support the geographic combatant commands, deter adversaries and, if necessary, employ forces as directed by the President of the United States.
