Seeing as bases don’t normally limit the number of territories being targetable - I can’t see it should/would for paratroopers (despite being a tech enhancement).
It would be a strange requirenment that all units exiting from one territory to be fixed on attacking the same territory.It would also make no logical sense to limit in that manner if viewing from a military strategical viewpoint. Paratroopers are shipped by airplanes. Airplanes can launch from one location and fly in what direction they choose. There’s just not a transport airplane piece in the game, but it’s ‘built in’ to the tech.
It would be like loading two transporters in one base and forcing them to move to the same seazone because of the base if such a restriction existed.You can rationalize either choice in any number of ways. All of the rules for A&A end up being rationalized, even if you could also rationalize the exact opposite rules.
I don’t really care which rule is chosen. I only assumed 1 destination because the rules appear to say only 1 destination. Also, this is not an “aircraft” like a bomber or fighter, this is a single airbase. Perhaps it makes sense that such a huge undertaking as a Airborne Paratrooper operation would require that each airbase only have 1 target. That could make sense to me. It at least makes just as much sense as requiring that the destination already have a land or amphibious attack under way.
It’s not ‘one airbase’ - it’s one infantry unit you move. So in that respect - I’d say it is like ‘an aircraft’.
