Here is my army composition on May 6th, 1941, the day I launched Barbarossa. Didn't assume military control of my allies.
1. stage:
One axis rush towards Moscow, which I captured in July(?). Then drive north to close the pocket. I forgot to fire the "continuation war"-decision which is why the first pocket was rather small. When I took that decision, it was already too late. The Soviets had no divs on the Finnish border when I closed the trap. If you get Finland to join the war when you launch Barbarossa, the Soviets will move a lot of troops there and your first pocket will be much bigger!
2. stage:
In October just before winter broke out, I launched the 2nd stage after having amassed my mobile units south of Moscow. A straight drive towards Donezk and beyond to trap the entire Ukraine. The Soviets have the bulk of their army there because of the Hungarian and Romanian forces. Instead of sinking all convoys, I simply capture the remaining Caucasus ports, then simply waited until spring to starve the unsupplied Red Army. In spring 1942 I quickly seized as much territory around Stalingrad and further east to trigger Bitter Peace.
It helps if you build some fortresses along the way (mainly on the yellow arrow towards Moscow). With Todt as Armaments minister, the Siegried-line event and construction tech, you can build 1 level of land forts within 2 months! I fortified the yellow line with lvl.4 forts which rendered any Soviet counter attacks moot.
Basic tips:
- Have the maximum amount of SS-troops built. Mot, Armour and infantry. The urban fighting capabilities are sweet. You can easily capture cities (like Moscow) with your armoured spearhead SS troops.
- Mots with AC attachment only, anything else will reduce speed.
- Move infantry mainly with strategic redeployment.
- Usual blitz: SS mots rush ahead, tanks follow, strategically redeployed infantry hold the ground. The second your mots capture a province, pause and strat redeploy 6-12 infantry there. The tanks will hold the province until the infantry arrives and then moves ahead.
- mots are your most important unit, due to the incredible speed. I hope vanilla DH will eventually nerf the 28 speed cause mots are seriously overpowered
- airpower: you can do with or without it. If used properly airpower is effective, but if you spend the IC in mots and tanks it also has great benefits.
