That's a lot of missile launchers... which means that you'll be sitting still shooting all game with your entire army. How are you going to take objectives without moving and wasting the expensive missiles' shooting?
You are also not taking advantage of orders - a vox network could help you here, especially with two CCS with nothing much else to do.
I would definately drop the medics from the CCS - too many points for too little gain.
You need special weapons in your platoon command squads or they are wasted.
You'll also need autocannons for taking out enemy transports - I wouldn't expect the missiles to be as good at this as they've only one shot.
All those missiles (what.. 20?) will hit on average 10 times per shooting round and you can expect some of those hits to be saved by cover... that's not that amazing for 1260 points... :shok:
I say ditch some of the missiles from your line squads, add commissars and meltaguns, add some vox-casters in and see what you're left with.
