...Wow, in 5th Edition, Primaris Psykers were kind of terrible, weren't they? No Psychic Defense, and generally weak powers on a Ld 9 model. Guess it's a good thing 6th came along and gave them the gift of real powers.
Anyways, about your lists--I feel you've made one important mistake. Your troops all appear to be of the Combine Squads type, but your Company Command Squad hasn't taken a Chimera (Command Vehicle is a great rule), nor have you taken any Vox's to make sure the Order come through. Anyone who sees you handing out Orders left and right is going to come gunning right for your Commanders--I know it's what I would do.
Other than that, your lists look alright. I'm not sure if the Veterans should be the ones with the Plasma, though--not when the Command Squad could mech up and go hunting with Feel No Pain to back them upifwhen the guns overheat. That does have the obvious disadvantage of putting your CCS closer to the action, though...
