Soviet infantry used magnetic charges to kill german tanks... Thats why the german tanks used Zimmerit...
The penal companies would dig shallow holes about 50 meters apart and cammo them, if they had time...
Then wait for the tanks to get close, VERY close, and attack like an army of ants...
NKVD Penal units were always used in this suicidal fashion.. Once you were convicted by a drumhead tribunal, for almost anything, even the most minor offence, the only way out was to Atone with your own blood!!!
Hard to get volunteers for certain death ya know!!!
