IC's ???

[Magister]

Japanese IC in Novosibirsk or Kazakh. Turns a survival siege into preparing a final offensive.
UK in East Europe. Final builds if Germany holds stubbornly.
UK in West Europe. Only If Germany made the mistake of insufficient counteroffensive power ready in 1-2 turns.

IC for Japan in the east indies is ideal IMO. 4 units per turn, basically zero threat of it being taken and right to india or africa with units makes this a great place.
