This is probably a really simple question that is certainly not limited to this A&A game, but applies to like ALL of them, BUT, this FAQ is where the action is atm…
If a player amphibious assaults a territory, with some units, and attacks the same territory with some land based air units (or even other land based units), which units are inelligable to retreat. ALL of them, or just the units that amphibious assaulted. ALSO, if the air units can retreat, can they leave before the amphibious units are wiped out, in essence abandoning them to their fate, or do they have to wait until all the amphibious units are destroyed before they can retreat.
Thank you! And sorry its not a Global40 specific question.
