Tom,
In the '70-'71 era MACV-SOG, Command Control Central (CCC) at Kontum ran the over-the-border operations known as Prarie Fire (Laos) and Salem House (Cambodia). Prior to '70 I believe they were known as Forward Observation Base II (FOBII). The 119th,57th, and 170th AHC's were the primary air assets for CCC. After the 119th was deactivated I went to the 170th at Kontum and flew on many of those operations (slick C/E). The only two mission names I recall were "Tailwind" and "Halfback". As I recall most insertions were Recon Teams (RT's) with only 6 - 10 men. I hope this bit of info helps with your search.
