vam I don't know if you are kidding me or that you just forgot about the buster calls we have seen, because the big bulk of crewmembers of the marine ships used are normal marines, in the enies lobby one there where two ships with only commander level and above however the other ones just had regular soldiers. Secondly Brook has actually stated both in the anime and the manga that he was a part of some country's army before joining the rumbar pirates. And that when he was in the army his mates gave him the nickname humming brook/swordsmen. Vol. 50 Chapter 489 and Episode 381.
