Are there any precedence in the fluff for Space Marine Tactical Squads with non-standard equipment (ie. not boltguns)? Specifically, I'm wondering of Tactical Squads are ever equipped with boltpistols and chainswords if the situation dictates it?
The reason I ask is because I'm currently painting up an Assault Marine heavy Blood Angels army, and would prefer to keep the army within the same company so they can all have the same colour droplet on their right shoulder pad . I'm using a combination of jump pack equipped Assault Marines and Rhino/Razorback-mounted Assault Marines, and I figure I could paint the ones without jump packs with red helmets and mark them as Tactical Marines (but of course using the rules and point costs for Assault Marines), I could include more than 20 Assault Marines in an army, and still have the same company badge on all the models.
