@Admiral:
Probably answered several times before, apologies if so. If I buy surface ships in a country whereby the sea zone is occupied with enemy ships, can I still build there and do the ships have to fight when placed or in the other’s turn? Many thanks
You can always place in sea zones adjacent to your operable complexes, no matter what enemy units are in them. You do not have a battle at that time - it is the mobilize units phase.
During your enemy’s turn, they must decide to either leave or fight during their combat move phase. This is one of the times when you may move during the combat move phase and the move does not result in combat - to move out of a zone with enemy surface warships.
So yes you can build there, and no the ships do not have to fight when placed (nor can they).
