The Standard of Devastation says that all boltguns within 6" will be salvo 2/4 (pls correct me if I'm wrong since I don't have the codex...yet..).
Under the header "BOLTGUNS" in the BGB (p.56), all bolter weapons are included, including storm bolters and heavy bolters.
My question would be will whether the said banner/std will affect:-
A) All weapons under the BOLTGUNS header of the BGB.
B) "Lowercase" boltguns, hurricane bolters, t/l boltguns and combi-weapons
C) Only "lowercase" boltguns?
Personally, I'd go for option (B). What about you guys?
