I read the entire article and it's a great read. It's fascinating how much we romanticize about past cultures and how much if it is wrong. I love reading history and this almost always turns out to be the case. Digging into any topic reveals they are always far more complex and multilayered than the the common caricatures you find in media and in generalized accounts.

the KV-1 tank, which grinded Operation Barbarossa to a halt Your own link says the KV-1 represented only 2% of Soviet tanks there. The real key to the Soviet win is that they could endure 3:1 loss ratios and still outdeploy the Nazis at better than 3:1.
But even then, the KV tanks were only a small part of their arsenal; the Russians had settled on three different categories of tanks: mobile tanks (their very fast BT tanks using Christie suspension), medium tanks, and heavy tanks. The latter category included the KV-1 and KV-2 tanks, and that was the smallest and most expensive group, but also the group that would always be at the center of any attack or defense.
The reason the T-34 was such an important tank, is that it combined aspects of all three categories; it was intended as a medium tank, but it had Christie suspension like the BT tanks, making it faster than most other medium tanks. And due to its sloping armour, it was almost as tough as a heavy tank (against tanks at least; it was vulnerable from the air). This combination made it the precursor of the Main Battle Tank.
