I am just wondering why 40k ships need so many people. What are they doing all day long? Do they "belong" to the ship? If yes, are there also women on a ship or do they recruit the new guys from a spaceport or planet? I am planning a story that takes place on a ship and i just cant imagine what so many people should be doing there...
Is it maybe like a modern US aircraft carrier? They have many canteens and even a bowling alley for entertainment.
