So this is an interesting upgrade, it allows any ship to gain Counter 1 if the attacker is a squadron.
Now this brings up an interesting question. Now for a majority of ships, they only have 1 die for their AS battery, so this card is pretty straight forward.
But for for the Raider 2, which has both a black and blue AS battery, when it would be attacked, which dice would you use? Say a squadron attacks at distance 1, would you then get to choose whether you want to roll a blue or black die? This is how I think it will be, but I just want opinions from others to make sure my thinking is right.
Also as an aside, do you see yourself using this much? Me personally I think it is going to be awesome, especially for fleets that run a minimal fighter screen. Throw this on your flagship and enemy squadrons will want to think twice about attacking.
