"The Intercessor Sergeant may either replace their bolt rifle with a chainsword or power sword (pg 91), or take a chainsword or power sword."
So it says they can replace a bolt rifle with a sword, I get that. But it also says in the end that they can just take a sword. Does that mean that a sergeant can take a bolt rifle, bolt pistol, and a sword? If so then why would you ever swap your bolt rifle out for anything?
