Yes the kugalblitz is a tank in its own right. Therfore it can take tank shots and live easily. I also mind you that the t34/76 is ai not direct AT. So it won't outright kill the kugal in lile 3 shots. Also the kugals shots WILL penetrate rear armor. And even if it didn't the overall bounc damage is enough to kill a tank after a few barrages. Considering you had 2 kugals, then you did this even 2x as fast.
