Immobilisation was the realistic option rather than an outright blazing kill, and the Soviet Army could be creative towards that end...
This is interesting:
There is a 10-mm slit all around the base of the turret. AT gun and heavy machine-gun fire, effectively directed at this slit, will prevent the turret from revolving and thus seriously impair the tank's field of fire.
This is what happened to the Bovington Tiger.
A tank could be taken out of commission through damage to its optics which could be achieved by small-arms fire, though the chances of it happening are slim.
