One thing I thought I'd mention is that if the platoon ends up awol from the Empire we'll need to leave behind or kill off Kara because she'd never go along with that sort of thing. Not that I'd mind, when I first thought of her I figured she would be a temporary character. If we don't kill her we could perhaps put her on a bus (as they say on tvtropes) and have her show up as an antagonist down the road.
