I finally started reading the rulebook but still have a question for amphibious assaults. Can ships that cannot bombard (subs, dests, carriers) move into a sea zone where transports are unloading in a scenario where both of the following conditions are true?
- The sea zone has no enemy ships (not even subs or transports either) in the sea zone
- There is an air base on an adjacent territory but it has enough damage that it is inoperable, OR there is none at all.
This makes me think the answer is no - page 14 of the E40 manual: “Further, if enemy air units could potentially be scrambled to defend the sea zone, additional units may be moved into the sea zone to combat them in case they are scrambled”
