That sounds like the way i understand the rules. Moving to an adjacent sea zone then moving to a land territory in that sea zone is 2 moves. Therefore not allowed.
Generally speaking powers defend together. However in G40 there are powers that start off neutral (Russia and USA) or not at war with each other (like Japan and UK/France). You could have a case at sea when you attack a sz with units from multiple powers, and can ignore the units that belong to a power that you aren’t yet at war with.
Garg, I think you should petition government for a degree course on A&A. I would cross the Atlantic and sign up. I need an excuse to visit North America.
another example of this in action is attacking an enemy sub. He might (and probably will) submerge, but its up to the defender so the attacker needs to send enough hardware to the sz to win if the enemy defends.
Before you know it, every territory will have a Airbase / Minor / Navalbase, There will be more political rules than ever, and victory conditions will be reduced to “play until someone else gives up.”
I couldnt agree with you more.
