Thanks for the tips Stephenn, of curse you are right but it is very hard to pull this of. I used the Strafe and got rid off the Infantry but he had also a Panther for support so my T34s could not do very much and as i said, the ZISs did absolutely nothing to the KT.
Of curse i will keep trying...
Ah, and also the ZISs V1 ability got a few patches nerfed to the ground. Its worth sh.. now http://www.coh2.org/topic/21777/zis-3-tracking-ability-overnerfed/page/1
Except they reversed it and did not see that.
