yeah, I now how to fight, somewhat.
I've been in a few fights. Nothing major, but more like scuffles while out on town. The first one was a real eye-opener, made me take self-defense a lot more seriously. Never used any safety gear outside of a helmet and teeth-protector after that.
My personal style is a bit of a mix of boxing, Kraw-Maga and I've even practiced a few years a style called Han-Moo-Do. Doubt enyone knows what that last one is, so a brief synopsis: The aim is to subdue the aggressor with fast techniques and counter-striker leading to a joint-lock or a full submission hold or to put the attacker(s) to the ground for long enough for you to run away.
Han-Moo-Do is the source for most of my non-aggressive locks and holds, the ones I'd be most likely to use in the case 1-on-1 fight. Police doesn't like it all too much if you go breaking people bones or disconnect their shoulder-joints. Self-defence is one thing but to go straight for wounds that require a prolonged visit to a doctor to set straight isn't all that recommended.
But rule #1 all my instructors have drilled to my head about self-defense always applies: Run away if you can, don't fight unless necessary.
