I'll leave the actual "review" part to other players for obvious reasons, instead I'll throw some background info about individual scenarios or the campaign in general. So, if you wish, feel free to discuss and comment

RS 01 Prokhorovka
This was an easy choice for the opener. The larger Kursk North/South scns or even a battle with the entire salient may be cool from the German side, but they would have be too large and cumbersome for a new Soviet DLC. A Soviet player would sit behind several rings of fortified positions and watch the AI banging its head against those defences most of the time - not so great, IMO.
So we are at Prokhorovka -- a fierce clash of steel, esp. since the AI has a decent amount of high XP units, with some of the most advanced models at this point. Your main goal here is to smash stuff, preferably enemy armour. Suffice to say, importing a core army from Red Steel with all those unlocked specs and shiny commanders can help a lot.
You will also see AI units using camouflage patterns, and on top of it you get asked whether you want to keep this, or go back to standard team colors (plain grey for Germany). Regardless of your choice you can always skin your own units at will.
In battle you need to find ways to wear down those nasty Tigers, Panthers and the rest of it. As we are in the 3rd DLC even this intro battle is not meant to be too easy anymore, but after all it should be no problem to win on normal difficulty...
