U.S. Space Force trainees and staff from 1st Delta Operations Squadron Detachment 1, and Catherine Lovelady, Space Force change management team program analyst, pose for a group photo March 8, 2024, at Joint Base San Antonio-Lackland, Texas. The day marked the beginning of the Space Force roll-out of its Physical Training Uniform, its first finalized service-specific uniform. The Space Force will celebrate its fifth anniversary Dec. 20, 2024; this rollout is significant as the youngest military service continues building its culture and identity.
