I noticed the patch, too. I was in USAFSS 1965-1968. Arabic first... unused, then Vietnamese short course and PCS to Yakota, then Kadena and TDY to Da Nang and Cam Ranh Air Bases. Wynn Troutman
San Angelo has changed just a little since you were here, but I understand the SS change a little also after 79. It's always good to see fellow SS people.
Noticed the USAFSS patch. Have not seen one of those for a while now. I entered USAFSS back in 67 (after returning from an overseas tour), remained until retirement. Nice to see a fellow security service comrade.
