2 beginner questions

If USA declares war in turn 3’s income phase, the bonus is +25. +20 is if they don’t hold the Philippines.

The Germans have no destroyer present, therefore the defending air units can not hit the sub, and of course the sub can never hit planes. Think of it in terms of the combined arms rule, air units can only hit subs if they are combined with at least 1 participating destroyer, the difference with this particular combined arms is that it works while attacking and defending. In the scenario that you described, the sub would destroy the remaining transport without rolling and the defending fighters can do nothing.

Afraid not. However, if  you capture a Major Factory with more than 6 damage , it becomes (is downgraded  to) a Minor with just 6 damage.

That’s what I thought.

YES I would certainly say so.

You should give A2 a try and then A3 and then make a personal choice as to which you prefer, which version is more balanced for your playstyle.

For instance if you like to take risks than A3 is better because it rewards sloppy play more than A2(unstoppable sealion/IndiaCrush)
