The other question I had was has anyone used any of the anti-terror/kidnapping schools that are reported to be the latest experts.

I realize this isn't "I am lost in the woods and need to survive" type of stuff, but I also remember we had several folks that were 18-series folks from my branch, and comparable in other branches / countries present, as well as a few folks who make their daily bread in the desert as a contractor. Just curious.
