What are the chances an attacker in a self-defense situation is going to try a "submission" technique? I put "submission" in quotes because I don't expect that someone willing to commit violence against me would stop when I tap out, but that they would take the arm bar all the way to snap or a chokehold all the way to a blackout. Most of the time, when you need to act in self defense, I imagine it is one of two situations: A hothead wants to fight, or someone is reacting emotionally and channels that into aggression and violence Someone wants to coerce you into something (whether that is to do something for them, give something to them, or go with them somewhere) In Situation #1, I can't imagine that someone on an emotionally-charged rampage is going to want to get into a submission hold. They're probably going to want to get in a position where they can just rain blows on you, because they want to feel the impact of their fists on someone else. Or, if they want to do as much damage as possible, they may have a weapon instead. In Situation #2, I also don't see a submission hold as an incredibly useful technique. Someone who wants you to go somewhere I think is more likely to simply grab you, or else use coercive tactics like brandishing a knife or a gun, or or else disable with something like a taser or a chemical-soaked cloth. The reason I bring up this question is because a lot of the discussion I see about self defense curriculums is that they aren't tested in the ring. My Taekwondo self defense skills are not put to the test in the Octagon, so therefore those techniques are unrefined. But I'm thinking, I don't need to defend myself in the Octagon against a pro MMA fighter trying to set up an arm-bar. I need to defend myself against some random person on the street who wants me to give him my wallet or wants to throw me down and then punch or kick me while I'm on the ground. Am I thinking clearly, here? Is the likely defense situation going to be void of MMA grappling moves? How often would those show up by the attacker in a self-defense situation?
