I don't have any numbers on it, but I imagine MCMAP and the belt system helps with recruiting.
They have a poster about it that I've seen, been I think that's for internal motivation purposes only.
I really don't think most recent HS grads would be swayed one way or the other about the Corps upon learning that we have our own weird form of martial arts. If they're the kind of kid who likes punching people, they won't care if it has flair or whether they're only promised the opportunity to punch people weekly with no special haberdashery involved, e.g. the old LINE program. Either way, in most MOSs, they'll end up pretty disappointed about the lack of regular ass-kicking opportunities.
Its just the whole package that HS kids look at when thinking about joining the military, and if so, which branch. MMA is pretty trendy these days and when a recruiter tells the kid that he will get trained in MCMAP which was developed by MMA coaches using some Muy Thai and BJJ he will add it to the list of things he likes about the Corps. That plus running around in the mud with cammo face paint on and shooting M-16s and machine guns. Its something that distinguishes us and attracts a certain kind of motivated individual (for the most part).
I've never really gotten into MCMAP, then again as a reservist there aren't too many chances to get your belts up. As Motor T I am required to get a green belt, but really, who actually follows that?
I got a question about it though, flame me if it has been covered, since I didn't read this whole thread, but is there a rank requirement to the different levels of belts on the officer side? I know the enlisted side has that requirement.
No. Actually the higher up an officer goes, the less he cares about belts. More specifically, the less chance he has to take a week off work to go beat people up.
