Can I take the following and still be bound?
CCS in chimera
3 x vet squad in chimera
10 x bullgryns, power maul and brute shields
Yes, but take note of the change I made in order to do so
This would be a bound army, as is, but do I get the benefits of clear the area and objective secured from the Blade formation?
Unfortunately the answer is no, this would not be a bound army as is if you wanted to get the formation benefits.
The Emperor's blade formation consists of the hellhound, mounted vets, and company command squad and would be considered a detachment in its own right. If you were then to take the bullgryns, priest, and stormlord as part of a CAD the units within the Emperor's Blade are not counted towards your core requirments (the HQ and troop choices.)
So you would either need to take all the units in a CAD to be bound, or be playing an unbound list.
