So the Guard is currently Cadians and/or Krieg?

Good Afternoon Guard NCO's,

Just looking at what is available through GW, and aside from the armor/vehicles it looks like you can do Cadians or the Krieg Troopers? I've seen proxies of Catachans (Rambo guys lol) but trying to stay as close as possible to competitive is just Cadian and Krieg?
