I think the Russian CV is too deterministic, and the average has to be keep down to allow German breakthroughs. The Russian command control in WITE allows the SHC to exactly coordinate defensive withdrawls, building of fortifications, and knowlege of exact defensive capability (CV). The attack side of the CV might as well be 0; only an occasional isolated German unit can be attacked by swarms of Russian divisions. A quick fix to add confussion to certainty is to make the possible CV range for the Russians to be very large, and this spread would decline with the years into the war. The randomness would keep the average Russian CV the same, but allow very low CVs in some cases, and very high CVs in other cases. For example, suppose the average CV for a Russian unit is 1. In the current game, variation would probably have it somewhere between 0.5 and 1.1. This makes attacking impossible and forces stacks of Russians units for any credible defense. Suppose the spread was more like 0.1 to 4.0, still averaging 1.0 . A stack of 3 Russians units like this could have a CV ranging anywhere from 0.3 to 12.0, not counting fortifications. This offers some hope of attacking a weak German division, but also has the chance of being a weak defense. With a level 3 fort the range would be 1.2 to 48.0, with the average 12.0 . This forces both sides to factor in this uncertainty, and takes alot of gamey tactics out of the equation (Lvov Masterpiece, for example). The Russian player is encouraged to attack, because building an impregnable line is a myth, and it is the offensive capability of the defense that preserves the line.
There will now be a strong chance that the line will have several weak points, but extra attacks will have to be conducted to find them. On the other hand, historical tough fights early in the war can be simulated, and most important of all, the Russians should not become supermen in the Great Blizzard. The spread should decline with time, so that in 1942 it may be 0.2 to 3.0, and still averaging1.0 . The randomness should only be factored in at combat time, so German reconnaisance will only see the average. If Matrix is interested, I could develop some probability tables which show the point.
