Marc Brock, incoming DEL 2 commander, during their change of command ceremony at Peterson Air Force Base, Colorado, June 14, 2021. DEL 2, tasked with providing SDA, is focused on preparing combat-minded warfighters and readying cutting-edge weapons systems; presenting combat-ready forces and equipment; and if deterrence fails, fighting to protect and defend the space domain.
