Marines

Someone wrote that they assume 20% of crew = marines, therefore 100 Mass BB
will have 20 marines. There is an example towards the end of FTFB which
tells you how many marines a BB--a Victoria class, I think--can carry,
and they're not part of the normal crew. And it's more than 20, although I
don't recall quite what it is. Serves me right for leaving my texts at work.
