Make nukies helmet/mask acid smoke immune?

[Dickles]

I don't know if it's balanced. I'm not sure how other people feel about it. It's not really fun when all the nukies get gassed by a scientist suicide bombing/not caring about collateral. I just played a round that ended pretty much instantly when all of the nukies got caught in a hellmix. 

I know it punishes nukies that group up, but guarding the nuke is what you're supposed to do. If there's one group that should have acidproof stuff I feel that it should be nuke ops.
