@Battlingmaxo:
Along a similar line…what happens with an IC territory liberated by an ally when the capital is held by the enemy? If the UK liberates karelia while germany holds russia can the UK mobilize units in karelia?
See page 20 of the rulebook:
If the original controller’s capital is in enemy hands at the end of the turn in which you would otherwise have liberated the territory,
you capture the territory, collect income from the newly captured territory, and use any industrial complex there.
Note that you cannot use industrial complexes that you captured this turn (p.22).
In other words: Yes UK can mobilize units in Karelia - not in the same turn it was captured - but in UK’s next turn.
HTH :-)
