Been thinking on the Squadron Rules. Scoutdad and other when using them did the Dreadnaughts die alot faster. The SFU has rules that roughly mimc this in Federation and Empires not in SFB or FedCom. I don't see why we couldn't use them in ACTA with a cavot that when targeting a Squadron you have to target the smallest units first then work your way up the ladder. This is the way Carriers work with Inner and Outter Escorts already. Also since Carriers can usually field a 4 ship Squadron I am sure that could be mimiced by saying if the Squadron "Flagship" has a Command Trait of +1 it could add one ship to the squadron. This would be how you would get a CVA+ECL+2xDEs group. As far as a Battlegroup, Gunline, or a CVBG you could also say that you need a "flagship" with a Command +2 Trait allowing you to form 2 - 3 Ship Squadrons into a Battlegroup.
