OK, I didn’t really have air superiority at this point, but my tip still stands, here.
You attacked Ukraine with all air to make sure you took back the complex so I couldn’t build there - nothing wrong with that.
But then you had no air support for 5 infantry, 2 artillery in Bel against 3 infantry, AA. You had a good result, losing 2 infantry and wiping out 4 Germans. I understand not wanting to fly over AA (we just talked about FIC), but attacking small German stacks of ground with larger Russian stacks, really hurts the Russians.
So G6, the Germans attack Bel back with infantry and artillery, and the Germany lose 4 units to 5 Russians, so the Russians didn’t lose as many units as the Germans.
Except. The German units that countered Bel came from the North where they couldn’t help the main army in the Southern push, but the Russians that went to Bel were with the main Red army in Bryansk, so basically the Germans took out Russians from the North where Germans weren’t needed as much, so Germans in a weaker position traded with Russians that were in a stronger position.
