AAA's can't participate in an amphibious assault

[lenzls]

When an Anti-Air gun is already loaded on a transport with an infantry unit and that transport takes places in an amphibious assault, what happens with the AA? Is it stuck on the transport until you can unload it next turn?

My interpretation was that it can't unload because it can't take place in the combat move and you can't unload the transport during the non-combat move because it unloaded during the assault. Is this correct? Or can you unload units during the non-combat move even after an amphibious assault?

You're correct. The AA artillery is indeed stuck. AAA can only unload during noncombat (and can only be loaded during noncombat as well - they aren't permitted to attack, therefore they aren't permitted to move during the combat phase) Transports can only move/unload in EITHER combat or Noncombat, but not both.
So the AAA must wait at least until the next noncom phase, assuming the transport doesn't move again during the combat phase.

aber:
after an amphibious assault you can then in non combat, on a different transport, bring a AAA gun in the territory
