Colonel Beckworth patterned the idea of U.S. special forces from a mission he took part in with the British SAS, that is true. The training of U.S. special forces has nothing to do with the British, at least at this point. Plus, the U.S has quite a few different special ops groups. Delta, Navy Seals, etc. The Delta Force is supposedly the best in the world at close-quarters combat. I've heard of their training facility called the "House of Horrors".

This seems to be transforming into a "wee wee" contest, and I didn't intend to go down that road. I just disagree that U.S. special forces are "British trained", that isn't the case at all. They were initially modeled on the British SAS, but they have morphed into something else at this point.
