I finished Red Star and here are some notes from the last missions:
11. Yelnya, first planned Soviet offensive of the war near Smolensk
The safest way to play this is to do the same as Spike did (see his earlier post) i.e. use you superior numbers to crush the enemy frontally. What I did was a large pincer movement from north (Suyetovo) and south (Saveyevo) with the pincers meeting in the western edge. This will give the Germans supply shortage which only gets worse as you occupy more supply sources. In the south I had an engineer to build a pontoon bridge over the river. The possible problem with this tactics is the secondary objective of destroying 3 armoured units in 12 turns because your tanks are in the process of encircling the enemy and not where the enemy vehicles are. So it may be a bit of a gamble. However, I was barely able to make it with a desperate push on turn 12 (sorry aux guys

). The rest was just mopping up and being a bit sad I didn't have Forced Labour -spec. Luftwaffe is weak here - use it to your advantage.
12. Rostov, first liberation of a bigger Soviet city, albeit only temporarily
Surprising to see a very easy scenario so late in the campaign. I deployed some elite forces near Rostov to eject the enemy out. The rest were deployed along the Debaltsevo (NW) - Shakty (SE) paved road which gives a good defensive line with excellent interior lines to move your units where needed. The enemy attack against Rostov is weak and you can quite quickly beat it back and start your own counter offensive to take the secondaries. Main enemy attacks are directed against the NW - SE line mentioned earlier, but these too are not powerful enough against your entrenched infantry, tanks and artillery. It doesn't take too long before you can take the initiative here also. There are not much enemy units in other parts of the map and I ended up doing "The Gabe", so Tabula Rasa it was.

My fighters are beginning to gain on Luftwaffe's advantage though the Germans are still a bit better.
13. Moscow, player has to stop German attacks, then lead the Soviet counter-offensive
Grande Finale. It is good to play this from the other side (cf. Blitzkrieg). Neither is particularly difficult because you have elite troops at your disposal. I put more units in both flanks than in the center just like the briefing sort of suggests. In SE corner the idea was to quickly dispatch the enemy units thereby freeing units to be used elsewhere. This worked very well. The strongest enemy attacks come from Klin (north) and towards Kaluga ("southish") so your tanks can be put to good use in these areas. In the middle the attacks are sporadic and don't pose much of a threat. After a while you should have bled the enemy white and can begin your counter offensive. You get some CPs and RPs to help you and some of Moscow's defenders are put under your command. I'm sure I could have cleaned the map in the allotted 30 turns but the battle ended at the end of turn 19 (early victory) so I didn't. Luftwaffe has a lot of planes, but so have you. When destroying enemy armour, it is advisable to quickly take out one Pz IIIJ.
My core at the end of the campaign:
Infantry: 2 x marines, one each of heavy, guards, paratroops, engineers
Armour: 5 x T-34/41, 2 x KV-1/41, Pz.Kpfw. III J
Arty: 5 x 122mm A-19
Misc: BA-10 recon, 57mm AT, 37mm AA
Air: 4 x YaK-1 fighter, 2 x Il-2 tac bomber, 1 x R-5 recon
Not deployed: 45mm AT, Pz.Kpfw. 38 (t), DB-3 str bomber, R-5 recon
Red Star is a very good DLC and well balanced. It is also probably the first one in which all the objectives and rewards work without a fault so kudos to the devs.

Using all those commanders to boost the AI was an interesting feature. I guess it will be used in parts two and three also.
Two wishes for the next parts:
A new commander:
New unit (I really liked the Gebirgsjägers):
