Re: techniquies in street fights
You could face any technique from any martial art plus anything that naturally comes to people when they're being violent.
There's lots of people that will say that you wont fight a martial artist because we as a group don't start fights and that therefore you don't need to worry about anything other than punches. Out on the street, where everyones sober, maybe. In a bar or a club at 2 am after a good nights drinking they're as likely as anyone to kick off.
So I say you could face anything.
