Strat bombing is a good option and should be used against soviets, so that their massed inf doesn’t swell too fast.
But rushing to the front usually leads to high losses which germany in my opinion doesn’t have on the first couple of turns…
I have found that how to win the simplest is infranty blocks for germany too…
Turn 1. Destroy the british naval units totally and capture the convoys…
Buy 1 bomber and with the rest infranty.
Attacks should be made only strafing, destroy the inf blocks in east poland and baltic states, but don’t conquer them.
Turn 2. Buy with everything infranty or another option would be trans to mediterrean, depending where the allies used their ipcs…
Attacks now conquer either baltic states or east poland with every inf you got and help them with fighters. After that you should have a nice block of german infranty sitting in either place and for the soviets to take it back they must use a lot inf too and weapons (art, tanks, planes).
Turn 3. Depending you managed to keep the place with your inf, buy more inf, but buy 2 tanks and a fighter or bomber. If you didn’t keep it and the russians attacked very heavily in it, watch what they have in there, if only couple of art and artillery leave them be and make another strafing attack to destroy their block of troops and buy another big block inf and maybe sub to hold the allies a little depending how your sub fleet is still living…
Turn 4. Two options start 2 major attacks one from rumania hungary to ukraine, another to east poland. So that the soviets would have to choose which they will destroy they can’t destroy both and if they try they will probaly lose both attacks. Now if they do destroy either one hit with everything you got at them and hope that they destroyed the ukraine troops, because you can move the big block of inf to east poland and land your fighters to hold it completely…
Turn 5. you can figure out already…
This was just a quick run what you should do in the russian front. And I don’t think it matters in the front if you move your tank from africa to the soviet front. I would suggest you keep trying to take the africa completely, first thing is that it’s losses for the russians in ipc if you can take the africa unless the allies are wasting them on british or america…
