Speaking of Turn 30
The offensive is still on going, but mostly in the South, where ever there is a concentration of 2 German infantry divisions per hex, attacks just falter, or at best I move 1 hex per turn.
by this time, several panzer regiments are showing up all along the Southern front line, they make hasty attacks problematic [:(] but the offensive doesn't stop until it reaches the cities of Orel and Kursk.
its a good time to explain why there was NO offensive towards Moscow:
1 - to take the City, it would require an encirclement, much ground would need to be taken, however the entire area was fortified and station with the best German infantry and even panzers, by December those hexes where all level 2 forts, and no doubt the hexes in the rear where all fortified as well, we are talking about defensive CV levels of 50 to 60 minimum, because of bad mobility in blizzard its almost impossible to cycle divisions for a 2nd attack, in others words, a single defeat could mean dozens of good quality rifle divisions would do nothing for a turn, I can't afford to have high quality armies doing nothing in December and January.

notice my initial CV! I was very lucky to win this battle, I did 3 more battles a few hexes South of Moscow, all in similar circumstances that a got a victory and some others similar battles I lost, with heavy casualties, I don't have the enormous manpower or even armaments reserves to waste digital lives like this.
2 - From previous Blizzard experiences, I learn that there comes a point where amassing more rifle divisions just does NOT add to the overall fire power because of bad mobility.
its much more productive to attack where ST was not prepared, to force him the spreed out his forces so he doesn't simply concentrate all of is best divisions in one specific part and stop the advance.
3 - with reason 2, it made far more sense to send those armies South or North.
4 - there will be time to reclaim Moscow, no reason to focus on it this year.
Far North
want to give a shout out to the U-2s, these little bastards can be quite useful, Soviet modern bomber production is actually lackluster until mid 1942, but U-2s are plentiful, with a top production of 64 per turn
the nigh bombers are ideal to stay close to static fronts or dangerous fronts with enemy air superiority, since then I won't care for there casualties.
they also appear to get more kills per raid, they are mostly used to bomb the Fins to oblivion!
not to mention, I might get me some night witches

Battles
As requested to show off some battles, I will give 2 notable examples:
was surprised that I could pull this off, ST tells me that he keep the Romanians away from the fighting to avoid stuff like this, beating on the Romanians as Soviets is quite fun
a regular battle near Tula, what to take away from this is how my rifle divisions could stand up to a German attack, even in clear! the Initiative was truly mine, at least until the snow...
