Nice summary, Sgt. Wonko. A few minor points:
@Sgt.:
• If an air unit has no movement left at the end of a sea battle and the carrier it was going to land on is damaged or destroyed, that air unit is also destroyed. This air unit would not be able to retreat from that sea battle.
Actually, the air unit can retreat. It just won’t be able to move afterwards, so it will be lost (unless a new carrier is being mobilized in the sea zone).
@Sgt.:
• Alberta does not border any US territory.
This is under review.
@Sgt.:
• Air bases, naval bases, factories, and AA guns are considered units for the purposes of Italy’s NO for no enemy units in Africa.
They are considered units for all purposes.
@Sgt.:
• If a power’s capital is liberated all industrial complexes, naval bases, air bases, and AA guns previously liberated by a friendly power are reverted back to the original power’s ownership. The only exception is AA guns taken by an enemy power that are then retaken by a friendly power and not currently in a territory originally by the power whose capital has been liberated.
Actually, you’re talking about two different situations here. When a capital is liberated, only AA guns in the capital revert to the control of the liberated power. Any AA guns controlled by allied powers in outlying territories whose control is being returned to the liberated power are retained by those powers. The second sentence above always applies, whether the AA gun’s original owner’s capital is enemy-held or not.
