(although I would change the rules about how only 1 ship is present from your battle line at a time so that escorts can actually support the ships they are escorting).
I find this is easy to accomplish, as well as most desirable. I do it by assigning specific escort vessels to a specific ship in the line. The escorts batteries fire on incoming missiles.
In that way Light "AA" Cruisers come into play, as well as many smaller vessels such as Destroyers, Frigates, Destroyer Escorts and Gunboats.
This could be a vastly longer response but I'm sure you get the idea.
