USAF 9th Headquarters Squadron (9th CSG) hat patch. SIZE: 4"x 2". Glows. This insignia was worn by personnel assigned to the 9th Headquarters Sqdn. for the 9th Combat Support Group, 9th Strat. Recon. Wing, Beale AFB, CA. The "Group" was attached to the end of the designation to signify that these personnel were under the Headquarters Sqdn. for the 9th CSG, rather than the Hq. Sqdn. for the 9th SRW. Circa 1976. NOTE: Listed as "Used" due to the reverse being tacky to the touch. Does not appear to have been sewn to a hat. Your inquiries are always welcome!
