Out the gate, high praise for the community. Go Falls@!
My main angle is I think G1 ought to begin with full 10 Infantry. On balance, their movement will pair with other available ground-pounders to give you an untenable numbers advantage on a Turn 6 crash into Russia.
They won’t have the numbers, hommie-G will. That simple.
You can do this while pairing with a delay meta against US with Japan. This means that at best, you get a modicum of support fighters from ANZAC and/or India(UK East) that won’t change the calculus.
In theory, US could set up to land up to 10 added fighters in Russia proper before a Turn 6 attack, but that stop leaves them fairly open to a Japan attack, including and especially if Japan never starts the war.
If Japan never starts the war, US path to land fighters in Russia on US Turn 5 follows only one path; and on that path Japan can set up to destroy everything in SZ8…
