Harry is getting some good licks in, but I just don't think it is wise to push the blizzard offensive beyond a certain point after seeing what happened to Kamil. Kamil killed 50 or more divisional equivalents. It just didn't matter very much once the weather flipped over. The Red Army was simply to weak to absorb the inevitable Axis rebound.
The Red Army here is just shy of 6 million. This is pretty decent at this stage. But I'd want to get it up to 7 million going into summer, and I expect Harry isn't getting much more than 100k in replacements per turn now. That's why it is important imo to stop the offensive sometime in February and give the army a chance to grow. Between combat losses and attrition, it's hard to grow the Red Army. It's also hard to get forts going at all during the winter unless it stops and digs in and does so with several units per hex and lots of construction points.
If Harry merged too many units, of course, those replacements won't have as many places to go as he'd like.
I think he should stop after getting Tula and start rationalizing his lines going into February. His center is exceptionally weak in units. I don't see much point in shooting for places like Stalino or Kursk.
His motor pool is taking a beating, too. Fully half of it is in repair at the moment.
I'm having so much fun finally being on the offensive that it will be difficult to rein myself in. But I will take your advice as best I can Flavius. The main difference between Kamil and myself at this stage of the War is that his Red Army had about 600,000 fewer men. Surprisingly, even though he did destroy the equivalent of some 28 enemy divisions during blizzard, the size of the German army is about the same. I have probably merged more brigades than I should have, but I have also built quite a few of them. I think I have about 50 of them at the moment and may build a few more. Of course I'll need to have at least 275 APs saved up by April in order to build 12 Tank corps and attach SUs to them.
In any event, my plan is to call off the major blizzard offensive in early February. Though I'll probably continue atacking in some areas if I feel I have something to gain.
