He sounds like a Modern Army Combatives Instructor at Ft. Benning!
Trigger Time
Sounds like one of my Soldiers who bit a bouncers finger off. I asked him why he did it when I picked him up from the police station. He said " he was about choke me out and that's all I could think to do".
That video is filled with truth.
Yes it is, most people's $h!t locks up in a violent encounter. End it quick or lose quick.
The best fight is the one you don't get into but by god if you must fight there are no rules. Bite scratch kick punch stab jab punch whatever you have to just live and win. Lots of people want to look cool, fighting is dirty not cool
QFT."Learn to fight and maybe you'll get old enough to need guns."
Learn to avoid the confrontation that leads to the fight. . . . but if a fight comes to you, end it in the most expeditious manner that results in a win. ie, living til the morrow.
