Setup: Add 1 GE CA in SZ26 - represents German presence in Indian Ocean.
Setup: Add 1 GE AR in GEA - represents gun boats on Lake Tanganyika (can also add rule this unit cannot move).
Setup: Change GE AR in SWA to IN.
Setup: Add 1 GE IN in KAM.
Setup: Add 1 FR IN in FEA.
Setup: Add 1 GE SS in SZ18 - represents German presence in Mediterranean.
Setup: Change 1 OE CA to TR in SZ20.
Setup: Change 1 RU CA to SS in SZ21.
Setup: Change UK TR to SS in SZ2.
