U.S. Air Force Airmen assigned to the 7th Aircraft Maintenance Squadron prepare inert munitions for loading onto the B-1B Lancer during Exercise Global Thunder 2018 at Dyess Air Force Base, Texas, Nov. 3, 2017. 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.
