@FieldMarshalGames:
Kind of a silly rule? Finland was not Friendly to Germany? Would not being PRO-AXIS make you a friendly by default?
No. “Friendly neutral” is not the same as “friendly”. A country cannot claim to be neutral while allowing a beligerent power to move combat units into its territory. That neutrality must be violated in order to do that, changing its status from friendly neutral to friendly. Per the rules, this requires a land unit.
@FieldMarshalGames:
I know you are the authority on the rules, but I am curious what the actual verbiage of the rulebook states…
The rules say what I said above, in the section on noncombat movement on page 21 of the Europe Rulebook. “Air units can land in any territory that was friendly at the start of your turn.” They also say, “A land unit can move into any friendly or friendly neutral territory, including territories that were captured in the current turn.” This indicates that land units may move into friendly neutrals, while air units may not.
