U.S. Space Force Lt. Col. Amber Dawson assumes command of the 10th Force Development Squadron during an activation and assumption of command ceremony at the U.S. Air Force Academy, in Colorado Springs, Colo., June 6, 2024. The 10th FDS is one of four units that constitute Delta 10, and focuses on providing warfighters with the necessary doctrine to conduct the “fight tonight.” The 10th FDS not only produces Space Force doctrine, but it also codifies service tactics and plays a pivotal role in Space Force concept development to posture Space Force forces and designated joint and allied partners to prevail in a Contested, Degraded, Operationally Limited (CDO), all-domain environment.
