It‘s been mentioned, but remains true nontheless: If you‘re down to just your dukes and Timmy Talibunny without his buddy Kalishnokov, you‘re prolly gonna get ****ed up bad. But if you‘re going down, go down hard. Maximum speed, brutal violence, and unrestrained agression. Take any opening you can and be prepared to get hurt.
On civvy side, the best MMA is Avoid-Fu. Be smart and stay outta situation that could go bad. Like don‘t get dead just because Snake and Ox asked you to stop dancing with their old ladies, and you‘re drunk enough to take exception, and situationally unaware enough to remember you‘re in a biker bar full of Snake and Ox‘s buddies. If that fails and you wind up in the mix, then refer back to speed, violence, agression... you never know what a yahoo who‘s out looking for a fight might be packing. Better tried by twelve, than buried by six, simply because you were worried about Johnny Law when you should have been concerned with the shiv your opponent was carrying and stuck you with after you decided to walk away. If you can‘t avoid the fight or won‘t avoid it, then break the skid and take what comes.
