Why not ask if you need a transport to cross the Tasman sea. Heck, people can swim the English Channel so therefore no transport should be required, right?
Fair dinkum. This has got to be one of the weirdest A&A questions I’ve heard.
If an allied transport attempts to land in Denmark via sea zone 112, and I have three planes in Western Germany (with airbase), can these be scrambled to defend the sea zone against this assault?
Yes, it does not matter which territory the troops on the transport are invading. The amphibious assault is in the sea zone adjacent to a territory with an airbase, which is all that is required.
