Agracier, I had a look at your map but I can't really tell where the cities are. I can't tell if Grozny is included, is it?
I was thinking it might be better to shift the area more to the east and to the north.
The stock Kuban map already has Tuapse so that part of the map is not needed.
Instead, cut off the map in the west to just include Sochi, and try to get the Maykop oil fields further to the north. More land mass in the north and less Black Sea in the south.
Good areas to include: Sochi, Maykop, Pyatigorsk, Terek River region, Grozny.
During the summer and fall of 1942, the Germans tried to push through the Caucasus mountains. They tried to cut through several valley passes to reach the coast and cut off the Russian army at Novorossyisk and Tuapse. Heavy fighting stopped the Germans but they almost reached Grozny. The Russians had several airfields around Grozny and they also held the port cities on the coast with harbors and airfields.

If you can get the map with textures and rivers, then I could populate it with objects and airfields.
Thanks again for your interest in this map!
Oh, and if you need help in translating the Russian cyrillic names then I can do that.
