Are you saying shooting is not a skill? True anybody can pull the trigger and get lucky or spray and pray but to put your shoots on target while under stress is a whole differant beast. in fact skilled/trained Police Officers who Hit 80% + at the range hit closerto 30% during a real confrontation. while it may not pass muster as an art. However they are a reality of todays day and age and the ability to handle firearms is most certainly a martial skill
i assume your talking about point sparring rather than worring about how good your opposition is. Focus on what you do well find a couple combos that work for you. like maybe backfist, rev punch.... or what ever then practice alot work on speed.
The problem that I have with kicking the knee is that, although it is a good target, is the possibility of a lawsuit being thrown your way. but if it is truly self defense My goal is making it out in 1 piece Ill worry about the law suit afterward.
it depends its all about situational awareness. the last place i wanna be is on my back in the guard when dude 3 buddies show up. how ever there are times when that position might be better than standing.
