That is not the best analogy. A better analogy would be if the military got rid of rank. That would be the equivalent of a martial arts school getting rid of belts.
I don't want to sound like I'm continually jumping on your comments, but I don't agree with this comment either. The military has a uniform, standardized ranking structure. If you are in the Air Force for example, you fall under the same standards for promotion in Tampa as you do in Turkey. For example, you need to take a test within your specialty code. The test is the same regardless of where your stationed. Certain exceptions for accelerated promotion are in place, like the 'below the zone' from E3 to E4 but again, you have the same opportunity regardless of where you stationed.
It doesn't work like this in the martial arts. Even within the same organization or indeed the same school it can (and often does) differ. In KKW TKD, a Korean child can make first Dan in less than a year. Here in the states it can be two or three years. And it isn't because they're better. It's just that way. And from art to art it becomes an even bigger problem.
If you walk into my school and I see your BB, well it means nothing. That isn't a flame or insult, just being factual. The fact that you have a black belt could mean you're hard core or it could mean you attended a weekend at someone's school and your check cleared. I won't know which until I see you perform. If I go to someone else's school I don't expect them to be awed by my belt. I expect what I have to offer to speak for itself.
Thus maybe your belt has some sort of meaning within the confines of your school, and that's fine. But once you step out of the door it is a piece of colored cloth to stick in the work out bag until you come back. Nothing more. It's main purpose is to hold your top together.
