Don’t forget that defending AA Guns can be taken as casualties now. In a battles where the attacker is strongly favored to win, AA Guns will typically be the first caualties since they don’t add any dice to the battle past the initial AA phase. In effect they become free hits. In battles where it is less clear that the attacker will win the defender has to decide when/if to lose the AA Guns, similiar the decisions now made regarding when to lose defending Strat Bombers.
Aw man, I HATE that situation. You have a certain amount of men, tanks, etc. and a stack of 4 or 5 bombers. Do you protect those expensive bombers at all costs? Or do you get rid of the low defense hitters in favor of men and tanks that hit harder on defense? Usually, if I think I have a chance at holding out, I will protect the bombers at least until all the men and artillery are killed. It depends if I have fighters defending or not. If I do, I will also let the tanks die to save the bombers.
Now, If I don’t think I can hold out, yeah the bombers go first so hopefully I can take as many attackers with me as possible. Problem with this is on a few occasions, I ended up holding the territory but now I don’t have my bombers for a new attack. Sometimes that setback is all the enemy needs.
