Figure a crew compliment on par with one of our WWII destroyers for the Raider.
Don't forget it's Star Wars, though -- droids and heavily automated systems.
True, but they still had way too many gunners. A WWII quad 40mm mount had 5 guys in the tub. A mount captain, two loaders and two gun layers. (Or maybe 7: 4 loaders) Of course there was a bunch of guys passing ammo when the ready rounds were exhausted. In Star Wars they're using directed energy weapons. No need for ammo handlers. Guns are sensor directed; no need for gunn layers. You need one guy to push the ON button. Get rid of some of the turret crews and send them over to damage control and engineering. You need more pocket protectors to maintain the automated systems. Without the white hats the urinals wont flush.
