PRINCE SULTAN AIR BASE, KSA --   U.S. Air Force and U.S. Army personnel participate in an after-action debrief during a counter unmanned aerial systems exercise at PSAB, May 27, 2021. Several security forces units across the base, including Royal Saudi Air Force members, joined the integrated training event to practice and refine anti-drone tactics, techniques, and procedures. The training allowed USAF, U.S. Marine Corps and RSAF personnel to learn from one another while strengthening partnerships and enhancing base defense capabilities. (U.S. Air Force photo by Staff Sgt.
