As far as taking over friendly neutrals, why is Anzac not allowed to? Is this a error in the rulebook?
…
So it is an error of omission?
There is no exception for ANZAC regarding non-combat-moving into friendly neutrals.
What do you have in mind?
(ANZAC is not part of the Europe ruleset, so they are not listed in the Europe only rules. They are of course part of the Pacific (and Global) ruleset.)
