try to engage them with a combination of ZiS/Guards (from Guards Motor Coordination Doctrine) and AT nades or mines.
When I engage small tank with 2 guards (with support of sniper and penals) it ussualy safely retreats being almost destroyed killing 6-10 models of guards dealing economic damage. And taking much less damage cuz repair is free. After that I play from behind and it just snowballs.
Generaly
I dont see how I should engage luchs with guards cuz A click gurds vs A click luchs is win for luchs.
Will try zis and guards. I played one or another.
Another bad thing for me is that zis not so good dealing with OKW shooting buiding, while SU85 is exelent against it. So now for me SU85 is 100% better than ZIS, but may not worth its total price (not only unit price, but price in general )
I wonder how much ZIS barrages it takes to destroy OKW shooting building, or maybe I just can use "attack ground"?
May be I will also try 2CE > 3 penals > 2 guards > 1sniper > 1 SU85 with an effort to get IS2.
Very Bad also that in coh2 there is no unit test map. So I should ask so many questions. What you think of engaging luchs with guards inside M3 to avoid MP loss if M3 is not desroyed?
