I have read tons on this story. A lot of it has to do with a conflict between Teti and Mykel Hawke. If you guys don't know, Hawke had a show called Man Woman Wild, and a few other shows. Hawke was also Teti's commanding officer when he was in the service.
Hawke is the one who outed Teti on some things, but the SF group dumped him after doing their own research.
As for "off the books" secret missions, The things that Teti has claimed didn't add up with the times and records that ARE available.
Not saying he never served, he did. But what has been brought out are what I would call exaggerations of his exploits.
If anyone wants to dig into this, go on Mykel Hawkes facebook page.
End of the day, I had stopped watching it anyway. As soon as Teti drank his own pee to get a psychological advantage.... his words.... I knew he was doing things to make a good tv show, not to show me the best survival choices.
