Good Post Chris. Please note I have broken a an arm as have some of the folks here.
I am not sure that those experiences help with my training though it was my training that "helped" me break those arms. So there may be a disconnect there.
For example every LEO certifies with their firearm every year. Most and some of us soldiers also enhance this training with combat pistol courses. Learning to fire their weapons under duress.
Most of them never shoot anyone during their entire LEO Career. Does that mean when the time comes their training will be of no use because they have never actually shot someone? I don't really think you believe that. I have watched your Your You Tube Videos and you guys look serious. I admire that.
Personally I happen to believe the old saying (To paraphrase) "The more sweat in the Dojo The less blood on the street."
In any Martial Practice the Martial Mindset/Spirit is Earned. Never Given.
