Being ex-military and enlisted, I have seen plenty of fights. Nothing is worse then someone who has taken martial arts for a period of time and then wanting to jump bad on someone who is a decent bar fighter. The look of confidence, then "oh shit...." when their stuff doesn't work is almost priceless if it didn't result in pain. Unless you are real good at it then it's useless for offense.

I took some martial arts way back and I can honestly say the I never got good enough for me to consider the offensive techniques worthwhile in a feal fight, but the defensive techniques were quality and I still find myself using them today when me and my son are fighting around for fun.
