As to the statements that the T-34 was hopelessly outclassed by the Tiger, let me just say that wars are not won by small numbers of armored behemoths with slow rates of fire, poor cross-country performance, and horrendous reliability. Wars are won by well-designed machines that don't break down every other day, are easy to maintain, can be used in all types of weather and over all types of terrain, which crews can be easily trained for, have a reasonably effective weapon for use against a multitude of types of targets, and...most importantly....can be easily and rapidly manufactured, improved, and updated.
Twenty T-34s were manufactured for every Tiger produced by the Germans. That's why, when the war ended, T-34s could be seen in Berlin, and no Tigers were in Moscow.
