The 525FS is a USAF unit assigned to the 3d Operations Group and stationed at Elmendorf AFB, AK. The combat-ready fighter squadron is prepared for rapid worldwide deployment of a squadron of F-22A Raptor aircraft to accomplish precision engagement of surface targets using a wide variety of conventional air-to-surface munitions. The 525FS trains in the fighter missions of strategic attack, interdiction, offensive counterair (air-to-surface), suppression of enemy air defenses, as well as offensive and defensive counterair (air-to-air). I found this patch in a Korean embroidery shop, it has the “theater-made” feel with the ‘cut’ edge, and does not have velcro attached.
