There has been a some talk about Soviets not fighting forward, and German supply being under-powered (or over-powered, depending on the poster), and fixes needed for the game, etc.
One thing that would help the Soviets fight forward would be if cities could provide some supply to Soviet units that are otherwise isolated. In another words, after a turn in which Soviet units are isolated, the next turn the German is basically facing a bunch of ants that they can mop up in short order. The game might actually provide the units some supply- I don't know and I don't care- what I am getting at is the CV reduction.
Also, I do NOT have any references to how cities were or were not able to provide supplies, I do NOT know the page/paragraph in Glantz's book that details this and don't care lol.
What I do know, is that in this GAME, if a city would provide the Soviet some CV protection, I would be much more likely to defend it knowing that if I was able to hold it, my CV's would not drop to 1, and those units might last longer than one more turn.
Maybe this could be modeled in game terms by providing port supply?
