I agree, Teddio; the Soviet T34 was (arguably) the
best all-round tank of WW2. Its main armament was
only a little less powerful than the Tiger's, but it was
fast and reliable.
The Tiger was built to carry the formidable 88mm. gun
so it was heavy, slow and over-engineered.
In contrast, the T34 was cheap, cheerful, easy to
manufacture and staggeringly effective. The battle of
Kursk was almost a foregone conclusion thereby.
The Germans learned that size alone is not the main
criterion in tank design. The Elephant was designed
to be bigger than the Tiger, but it couldn't be used on
normal roads. A bit OTT. so back to the drawing board.
