im sorry i realy wrote a long post on your list but deleted it by accident, so im going to just say the bad things in this one:
bolt pistol - swap for boltgun looks like this squads a shooty one afterall.
smoke launchers - what do you need these for?
plasma gun - i think this is a bit of overkill in combat patroll but its food for killing SMeqs
you need to tell us your regular opponents so we can advise on tactics.
