Well the history lesson is all well and good, but my beef with the Karelia/Archangel stack, has more to do with the gameplay mechanics, than with the history.
Its generally safer to stack and shuffle troops to Russia, then it is to confront G in France, so many players have adopted this kind of strategy as a matter of course. The new Russian National Objectives are good step in the right direction, since they provide an incentive for the Allies not to do this sort of move.
I worry that it won’t be enough though. Compare the extra 5 IPCs per round from the NO, to more than 24 ipc worth of units that the British can park into Archangel. This might be one of those National Objectives that gets trumped by the need for boots on the ground.
