@Yoshi:
This means that if UK want to kill these subs, and that the 8inf are in Finland, then UK cannot load them ?
Since the sea zone isn’t hostile, the units in Finland can be loaded. However, since the UK is attacking, the transports must either remain and be involved in the attack, or move away during combat movement. As a result, the only way the units can loaded is to use them for an amphibious assault.
@Yoshi:
So UK cannot ignore the subs to load the units and attack them in the same turn ?
Not unless it’s attacking with the units.
@Yoshi:
But then I would have another question : UK has plenty of boats in sz2 (including destroyers, and to simplify let assume that they have no more air power), germany a sub in sz8 and Italy some boats in sz12. Then, UK has to choose between attacking sz8 or sz12 ?
Not at all. Subs can always be ignored during movement. The attack doesn’t happen until after all combat movement is completed. Some UK ships can stop in sea zone 8 to attack the subs, while others move through to sea zone 12.
