Fascinating thread. I am trying to wrap my mind around the idea that it takes 391 sailors and 22 officers to ferry 500 marines around. I mean, think about it - the purpose of the ship is to be a taxi and floating hotel.
With 391 sailors, do the marines get room service?
By commercial standards, Navy ships are always overmanned. That's because the Navy figures casualties and damage control ops into the manpower requirements.
