Amphibious Assaults
I understand that air units in the land based attack of the amphibious assault are abel to retreat .
1. Must they all retreat together as one group at end of same combat cycle (to friendly space limited to number of flying spaces still available to them), or can they retreat as individual units during different combat cycles??
Non-Amphibiousl land/naval attacks
2. Must all air units all retreat at same time as all other retreating attacking units, or can they retreat during a different combat cycle to other retreating attacking units?
3. If they can retreat separately (ie on different combat cycle to other attacking units), must they retreat together as one group at end of same combat cycle, or can they retreat as individual units during different combat cycles?
