I learned ka-fighting:
Ka-nife
ka-chair
ka-gun
Just like gun training with drawing and movement, unarmed or impromptu fighting must be almost second nature. You have to do it a few times, and not in a controlled environment, to truely understand it. I have been in a few scuffles at bars (drunken morons, the same buff, kick boxer wanna-be types that drink too much and watch too much ultimate fighting). Most "fights" one will ever get into is with drunk people as stupidity surrounds alcohol. The basic Army hand to hand will get you through most of the crap you will see out there. Very simple, easy to enact and effective as hell. A sharp fist punch to the eyes or a side foot kick to the knee will drop a guy down quick, or take him out of a hand to hand fight. Its worked for me. Im a little squirt, so I have to know this stuff works!
In all seriousness, dirty tricks will get you through alot too. May seem down and dirty, but gouging out someone's eyes works wonders. Jerkface cant see, drunk, first instinct is to run, blindly runs into wall, knocking himself out. Ive seen that once (I wasnt fighting, thank god, guy was huge) at a bar in Plainfield. Made a real mess, but worked!
I wonder if John is on these boards
(Guys at Eagle Creek will know what I mean). My thought is to have a back up, then a back up back up. To quote Captain Jack Sparrow, "He who runs away, lives to run away again!"
