Havent made a suggestion for a long time, here I go again. First thing I'd like to suggest is the GAZ-67:
Now I suggest this because I personally dont wanna see a Willy's jeep on the fields of Russia. I know they were produced with license from US in Russia, but I think it feels wrong to have it widely used in Eastern Front. Im not saying dont even use it, just use it only for Pre-1943 maps.
Next is the Zis-5 Truck:
Again, I think its fine to have a Studebaker US license truck, but we definately need to have the ZIS_5 too! To give the feeling of how out-of-date vehicles were used by the desperate Red Army at the time.
I also love trucks, and how this beauty looks
People, please dont go "Devs are allready notified about things that are common herp derp..."
Cheers!
