An idea from Rapid Fire. It gives soviet battalions a random quality attribute.
The rule: To add uncertainty for a Soviet player throw 1d6 to determine the quality of each battalion when it first time it needs to know (i.e. is involved in close combat or rallies). 1-3 Green; 4-6 Regular. Regardless of the die roll all support weapons, guns and mortars, are Regular.
Interesting enough to write it up but I’m not sure it makes for a better game.
