In my experiences if I have to go to the ground with my enemy it's taking to long. To much energy is being wasted. In my training I have to go through 5 people or more before I get to my target. KARATE is a dance I do not have time for. If someone chokes me ,he is now a combative. Brake the elbow, WWII open hand to throat get behind him and snap the neck and on to the next. I did KARATE for a long time. Then because one of our black belts were hurting the other students, the owner brought in special person and eat the black belt for lunch. At that time it changed the way I would fight for the rest of my life. Just saying.......
