It is an old idea od Caspian Sub of organizing the transport from US to Europe using two sets of 4 transports via EC.
But the major difference is you do not land in WEU but you go through UK and Norway. The difference is that while Germany can deal with isolated landings in WEU or SEU, or prevent them to occur altogether, the Norwegian way reinforces the push in each round with the new units, while you preserve almost all of the original ones so that when you enter neighbourhood of Germany – EE in this case, you have such a mighty force there, Germany cannot think of wiping out. Moreover it may allow Russia to reinforce it too, or a sweet 1-2-3 on Berlin.
You have two fleets operating, one mighty combined UK/US SZ5-SZ6, the other one SZ2 to ship the units from EC to UK.
Ideally you have 8 or more UK units in Norway when starting the push, you reinforce them with 8 US, next round you go with those 8 UK plus new 8 to Karelia, you reinforce with 8 US plus 8 new, thus you will enter the EE with about 20 UK units, 24 US reinforcements and anthing russia can spare and you would be able to hit Germany itself with all that brutal force.
It usually does not go that ideal, you might need to drop some units to africa, from time to time you might trade WEU in case it pays off, but nothing should destract you from this basic scheme, i would say. And there is another thing it takes four rounds from the units produced at EUS to get to Europe so it requires some good planning and patience really.
