There has been a lot of commenting about sport, combat and south Korean military TKD. What does combat TKD do differently than sport that makes it better or more effective? I found a site that promoted TuKong Moosul. This is said to be the martial art taught to South Korean Special Forces. This organization doesn't seem to teach much more except more theory/philosophy and wespons, but I would expect that from a art for the military. Thoughts and opinions?
