Re: What is "combat"?
I was just reading through your post. I hope you don't think that Kit and I think aikido type training is not a valid form of training. As obviously the Japanese feel it is worthwile.
Some Trivia: Who played a big part in the founding and shaping the Marine Corps Martial Arts Program (MCMAP)?
MCMAP does not look like anything to do with aikido. MCMAP as with MACP (Army), you can find all the basic underlying principles, but the methodology looks nothing like what you find in aikido dojos.
