It
was a tank slower in rough area than the heaviest T-34.
The need of the most powerful cannon and a better shielding
were rapidly obvious. In March 1942 it began the production
and was assigned like unit of support to the infantry.
Nevertheless, the only man of the turret
was unable to coordinate the actions with the rest of the battalion's
components at the same time that it was shooting, and for 1943
they were totally inefficient in a clash against the German
armoured vehicles, being stopped making. 8.226 were constructed.
