"One Noise Marine per 10 models" is pretty clear I'd wager. At least that suggestion wasn't a part of the list, though sometimes there's backdoor ways of getting around things. Hey @neferhet, how did you come up with this?The way I read it was that you can only have one blastmaster in a 10 man squad though I may be incorrect.
10 Noise marines, 2 blastmasters, icon of excess, rhino w/havoc launcher
