sent lone fighter to battle it lived… do i have to land it or can i crash it?
I assume you’re asking because you committed a carrier to pick it up. If the carrier can still make it there, you must move it to get the fighter.
Can Battleships and Destroyers fight planes? Can planes fight sea units? For example, can I take off from Midway and fight a Battleship? I know about Amphibious Assaults and Battleship Bombardment, but aside from that is what I am asking. Let’s say the Battleships are next to a battle, can they fight? I know that’s a lot of questions. Thank you for any help. I could not find it in the book.
Submarines do not fight against air units.
Everything else - transports, subs, carriers, destroyers, battleships - do. Of course, transports have no “attack” value, but transports can defend.
A battleship that is NEXT to a sea zone or land zone in which fighters are involved takes NO PART in that combat. (unless for battleship bombardment, which you already know about). So if you have a sub in one sea zone and fifty battleships in the next sea zone over, the lone enemy fighter that attacks your sub is perfectly safe.
