Put this under the GM section first. Whoops. Works better here.
I ran my first Rogue Trader game about a week ago. We all had a blast.
I tend to read the rules and run with the big points and let the little stuff slide. Usually I'm for story over game mechanics. As a result I may have missed this in the book. The helmsman rolls his Pilot (spacecraft) skill + any bonuses from the ship for maneuver actions whereas the gunner only gets a basic BS test for shooting. Did I miss modifiers for type of guns, any kind of cogitator assistance (targeting), speed and current maneuver actions, or any kind of specialized skills (ie - starship gunnery, macroweapons, etc...)?
