Hm, according to the new codex, the sergeant starts with a laspistol and can upgrade to other pistol plus power weap, I personally don't enjoy this, cause I never see the point in what a single pistol armed sergeant can do..
And is it me or the officer can't choose wargear as he used to do in the older codex? Another question is.. what happened to Armoured Fist squads? And why are hellguns now Ap3?!
