@Cdr_Ian:
1. So a defending sub can submerge and always ignore battles so their would be no point in attacking them
2. So may as well leave carriers for defensive duties and movement during the non combat movement phase.
Thanks man
you’re welcome
By the way, there can be some specific cases that you may need/choose to sacrifice an aircraft, for example with the threat of a Sealion, the UK may want to move the Gibraltar Aircraft carrier in with an air-attack on SZ112 (if the German fleet, with transporters is positioned there). The 2 extra hits may give the air force the needed slack to take out the enemy fleet, and surviving air units can still land in the UK.
Or, more extreme, if Germany puts surface fleet in SZ112 and ungarded transporters in SZ113, then those can be taken out by 1 single fighter, in case it has a place to land, so for that you would need the carrier to attack SZ110 (in case it is occupied), even though it is doomed*. In this case you’d probably sacrifice both plane and carrier, so it would only be worth it if there are enough transports to be taken (5 or more, i suppose).
*i’m not sure if it can attack solo or only accompanied by another unit
