If I have a squad of Vanguard Space Marines (Close Combat Fast Marines w/o jet packs if I got the name wrong) with CCW/Bolt Pistol, and a Captain joins the squad with Power Weapon/Bolter what would happen if I tried to shoot, then assault in the same phase?
A) Can I choose to fire just the Bolt Pistols, and not fire the Captain's Bolter, and still assault because the Rapid Fire weapon wasn't used?
B) The whole unit counts as firing, wether or not I roll anything, so the Rapid Fire weapon stops the squad from assaulting?
