So I got a question for the group/Sam, at least until they FAQ it. DOES the DA Devastation banner work on Hurricane bolters? FOr those unfamiliar, there are fundamentally two possible answers.
1) A hurricane bolter is nothing more than bank of 3 twinlinked bolters.
2) That's just a fluff description, it's really it's own thing, just like a storm bolter is different than a boltgun.
I tend to favor the latter interpretation, because after all, a weapon destroyed result would take away the whole hurricane bolter, not just one of them, and likewise, when you use Power of the Machine Spirit to fire an extra weapon, you fire the whole thing. THat, to me, means it is its own distinct entity. But on the other hand, they do call it "3 twinlinked bolters", you're even asked to extrapolate it's number of shots, range etc, that way, and GW has totally used fluff to drive rules before, going so far as to label even mandrakes "demons".
But then again, Sternguard can't use their special ammo in stormbolters, even though you gotta figure they fire the same rounds.
