Assaulting tanks

[Mowgli]

I'm wondering about this as well.
Just played Red Victory/Cherkasskoye PBEM and the opponent just blitzed forward with his tanks.

There was nothing I could do against that as the tanks (infantry assault value 20, as pointed out by Pepe) simply assault-obliterated everything in their way and utterly destroyed my Molotov-units before they even have a chance to use their cocktails. The AT-rifles are useless against Tigers (even at close distance from the rear at immobilized tanks; penetration is below half the rear armor...). The AT guns are positioned in a way so that they can be easily avoided. The only chance is that the opponent assaults into covered terrain, in which case he has a 25% chance to get stuck (and even then the tank sits on the objective!).

It does not feel immersive at all. Tanks on their own should not be able to assault in this way and easily obliterate a squad of infantry in trenches without any risk to themselves whatsoever. I'd be okay if tanks could move "through" the position, causing some casualties, but not destroy everyone in their way in a single turn.

In this scenario, it was probably particularly bad, as the Tigers have an armor value of 80, so they have an assault power that equals about 66 (!!!!) infantry. It would help a lot if - for example - the armor value (and corresponding assault power) would also be affected by facing/aspect. Right now, it only works for fire combat.

So, in this scenario, as I see it, your only chance to neutralize the Tigers is
1) to make them get stuck (a. immobilization chance if they assault into covered terrain; b. small chance during movement through difficult terrain)
1a) if they're stuck, you might be able to attack them: either with assaults (their combat power is now much reduced - they're now only about 3-4 infantry equivalents) - but for this you first need to pass a difficult morale test; or with Molotov cocktails (ideally: from behind, with fresh units that are not negatively affected by any status).
2) to whittle down their effectiveness (by throwing suicide infantry in their way?) until they're below 50% and can no longer assault - good luck with that!
