A B-1B Lancer assigned to the 34th Bomb Squadron, Ellsworth Air Force Base, S.D., thunders off the runway, kicking off a 29-hour Dynamic Force Employment mission to the U.S. European Command area of responsibility, May 28, 2020. The mission was not in direct response to specific actions taken by any nation, but rather enabled crews to remain ready to respond with lethal capability to any potential crisis or challenge across the globe.
