I actually like this tactic.
I view the the defense of WE as a luxury rather than necessity. If I can get away with a similar plan to what Switch suggests I’ll do that, but often times I really think that too much early defense or consistant heavy defense can stifle the threat on Russia.
I like my eary defense to be as few inf as possible with all my ftrs and arm because they have the mobility to threaten Cauc with one Non-com to EE.
As Germany if I have to choose between stacking EE or WE, I’d prefer to stack EE and keep the UK/US seperated from Russia.
At some point (between rds 4-8), I’ll abandon WE moving all inf (~10) to Ger or SE while the armor go to EE. With a placement of 10 more inf on Ger plus potentially leaving a few more inf behind in Ger while moving the rest to EE you can easily have a force of 25-30 inf + 10-15 arm (from EE) + ftrs to threaten a heavy Allied landing while you maintain a heavy push on Ukr (or Kar/Cauc).
So essentially what happens is you end up trading WE with 2-3 inf + ftrs/bom instead of having 10, 12, 14, etc inf + planes sitting there while the Allies stack Kar and box you in.
Now if you are doing extremely well in Afr or Japan is having a great game you have the ability to stack as long as you can still maintain pressure on Russia, but once it is clear the Allies are over running Afr and Germany’s income will be stuck in the 35-39 range it just becomes too costly to try and defend everything while still advancing in the East.
