Most fluid PzC East Front games?

[76mm]

I am actually playing the Fall Kreml center campaign right now...it is absolutely massive (thousands of units and 250 turns), but is starting to drive me crazy...

The Russians have two layers of bunkers all along the front. Artillery has little effect on the bunkers. Air has no virtually effect on the bunkers. Assaulting undisrupted units in bunkers has little effect on them. Then, once somehow someway you manage to isolate and disrupt a bunker with a couple of Russian battalions, it takes several turns of assaulting with several battalions to take it, as the Russians defend to the last man. Always. And then on to the next bunker, two hexes away. Oh, and about 95% of the front is completely static because there is no way I (as Germans) can even make a dent in the Russian defenses. I find this kind of game very frustrating and not very fun...hence the request for more fluid games!

I played the Moscow 42 Russian attack campaign and it was more or less the same experience in reverse--the Russians battering through the German defenses. Minsk is pretty much the same. I wouldn't mind playing the occasional game with fortifications but playing three huge campaigns with fortifications in a row is getting a bit old.
