[@Sep] I have some questions about some technical aspects, usually I'm not very science-y, but space and space technology gets me jazzed.

Kinetic and Plasma weapons, I'm not sure how plasma acts in space, especially in a condensed form such as ammunition. But I know that, at least ballistic weapons in zero gravity, the force of firing would push the shooter back. So with that, Kinetic weaponry, which is what I assume what the ships use. I could have misread or am simply an idiot, but wouldn't the force of guns that big push the ship around? How would you counteract that?
 
Also, Engineering division, I assume they would handle AI (With security assistance) as well as systems, engines, hyperspace, jump drive, etc?
