One class I took long ago was aimed at the guy at home protecting himself against a armed prowler.
It was taught by a Tempe Police officer, and included a lot of thngs I found useful for paintball (then).. Staying out of "fatal funnels", how to move in the dark and shooting techniques.
Came in handy in the CQB games. Now, maybe some of the things mentioned sound strange, but then again.. Something like "Executive Protection" might be interesting in a scenario game.
I'm willing to go and see what I can use, or not. -Got the time.
