16th Special Operations Squadron (16 SOS) "Spectre" patch
On 30 October 1968, the 16 SOS "Spectre" was activated at Ubon Royal Thai Air Force Base (RTAFB), Thailand, and assigned to the 8th Tactical Fighter Wing. The unit was equipped first with the AC-l30A Gunship and later with the more advanced AC-l30E/H model. Even before Spectre was a squadron, it was utilized by Special Forces in Vietnam. On 18 August 1968, a Gunship flying an armed reconnaissance mission in Vietnam's III Corps was diverted to support a Special Forces base at Katum.
