Hello to all. I had Pacific 1940 for a while, thought it was to complicated, and recently acquired Europe too. Now I have taken up on learning the game (even though I still haven’t played it due to the lack of space in my house for the board). So my first question is if air units can scramble to help defend allied ground or sea units in adjacent (or the same) territory/sea zone that aren’t part of the same nation. Also, can air units scramble to help defending units that are being attacking by non-air units? Another question of mine is if you have a submarine combined with other units in a fleet and you take a hit, can you choose to lose the submarine? I got confused with that in the rules. Also, if you run out of units (you build all your tanks and they all dies is an example) can you build more tanks? Do you have to substitute a household item as a tank? In addition, what purpose does the battleboard serve? I roll a dice for each type of unit (if 1 unit of that type 1 die, if 2 units 2 die, etc.) If the combat stat is 3, and any of the dice roll a 3 or less, its a hit. That’s how I think it is. Am I wrong and the battle board is supposed to do this, or am I mistaken and misinterpreting? Thanks for the help!
