ok, so i'm wondering, can you take things like doctrines, or the space marine chapter thingies (not real familiar with anything other than fighting the marines...) without breaking any of the mutable or immutable rules? or, if you do break them, which would you be breaking?
also, something else i've been wondering about, do the brute squads follow the normal rules for sentries, regarding things like say...sniper rifles? i can't find any reference to it in the kill team rules, but it does make note of it under sentries. just wondering.
thanks.
