Warplan is a World War 2 simulation engine. It is a balance of realism and playability incorporating the best from 50 years of World War 2 board wargaming.
Good to know they're not supposed to get there - as I thought it's how it should work. But presently they're here.
I'll have to decide on something but that's a clear cut case where rail from Sovietland bringing supply make Petsamo absolutely untenable, if it's down to just the port of Murmansk I can ship Germans in there.
Well technically as here Petsamo does not even have resources it can simply be abandoned and Axis defends down in the south.
I am not even sure that's the intent, these USA troops can just be railed in the middle of Russia to stall the Germans anywhere they like as these units will be large and though.
