This single sentence is a pet peeve of mine. It and it's numerous variations, when stripped down, form the basic thought that some martial artists can kill and some inexplicably can't due to a Pavlovian response to competition rules. I think the fallacy in stating ANYTHING similar to the thread title is that I know of no sparring sessions or class schedules that have "TO THE DEATH" as a criteria. So, from military to krav maga, I doubt ANY have proficiency in hand to hand lethality. As for the techniques, I don't think it takes a genius to understand that if you step on someone's neck, poke at their eyes, punch the base of the skull, and even more: you will increase deadliness tenfold. If you're a grappler, just ignore tapping . I feel that some pressure points are also a bit psychosomatic, akin to the students who crumbled to that one Instructor's "invisible punch" (y'all remember that? I can't find the video.) I honestly wouldn't post about this if I hadn't seen some intelligent posters signing on to that fundamental. This whole thread is made while acknowledging that putting different combat arts in a street fight scenario is ultimately silly. I'm not trying to be a dick about anyone training in a martial art that claims this or joining the military, I just like my fluff to be ironed out publicly. So, what do you guys think? EDIT: As an aside I was REALLY proud of making that Pavlov pun, until I realized not all competitions are started with a bell. I feel super disappointed.
