@AdmiralNagano:
In every other Axis game I’ve ever played (haven’t been Germany in global yet), the right way to beat Russia was:
Early game - build inf /art
Midgame - build tanks
Now that is a simplification, you need some naval units, you definitely need a big airforce, and these days you want mech inf too. But the basic principle for the ground war is to build cheap, slow units early and expensive, fast units late. Ideally, your tanks/mech reach moscow at the same time as the towering stack of inf and art finally gets there.
Something else I’ve considered is just pumping artillery first, then building mech infantry in time for them to catch up with the artillery stack. That would be very cost-efficient.
This has been our playgroup’s experience as well with Germany. Build up Fortress Europe first, then pump out the tanks. Typically whoever is Germany also tries to expand the Luftwaffe or at least keep it intact. The inf stacks are designed to absorb hits, while the planes and tanks destroy the enemy.
Of course, this was in Classic, Revised, and Anniversary. Our first Global game is tomorrow so we will have to see how this plays out in the new game.
