Blitzkrieg was ineffective against the USSR? No, it was simply too effective, relying on this tactic, the Germans were like a bamboo, quickly cut into the territory of the Soviet Union, broke through multiple lines of defense, divided and annihilated millions of Soviet troops, and almost even took Moscow. If this tactic was ineffective against the Soviet Union, what tactic was effective?
It was only in 1941 that "blitzkrieg" came to prominence, and it is still controversial whether this tactic was the first of its kind in Germany, but the German army at that time undoubtedly took it as the main tactical attack idea and successfully implemented it on the battlefield, winning one victory after another. Like Poland and France, they did not block the blitzkrieg, so what reason is there not to use it on the Soviet Union?
The early Soviet army experienced a revolt, the quality of the commanders and fighters was extremely poor, and the operation was rigid and dogmatic, but the number of their personnel and equipment was extremely large, even if some later viewers described the early Soviet army as piggy, they were also a solid armed force, and they could not tolerate half a point of fraud. Moreover, many people in the Soviet army participated in the "Winter War" in 1939, had the experience of bloody battles with Finland, and no matter how inferior they behaved, this is also an army that has seen blood, and it is not as garbage as later generations say. In the face of huge numbers, as long as the Soviet army drags the war into a stalemate, then they can exert their numerical superiority and exhaust and drag the German army to death.
Hitler understood this, and in his strategy, the Soviet Union was already part of the quick battle, the Fuehrer did not expect that the Soviet Union would be a pot of paste, he hoped to quickly solve the Soviet Union, and then turned around to deal with the British with peace of mind. In this way, blitzkrieg becomes the only way to play.
Many people think that Hitler is too arrogant, which I do not deny, but if you arrange strategy and deal with the Soviet Union tactically, you really can't find any better tactics than blitzkrieg. Hitler was also worried that the German army would be dragged into the quagmire, and hoped that Germany would have access to the Soviet Union's Baku oil field, which accounted for more than half of the Soviet Union's crude oil production, and as long as it could quickly advance to the corresponding area, the Soviets would sooner or later lose to insufficient resources.
As mentioned earlier, the early Soviet army had no characteristics except for the number, and the vast land of the Soviet Union was also the most suitable place for the mechanized troops to unfold, and the Soviet army did not have a complete mechanized assault thinking (in fact, there was, such as Tukhachevsky's large-depth theory, but this was a taboo topic in the early days of the war, because Tushi was purged), then it was necessary for the German army to strike a thorough and murderous blow before the Soviet army learned and adjusted the corresponding capabilities.
The German army was actually a blitzkrieg and a blitzkrieg, a tactic that did not work at all times, it required the command art of the general and the control of the fighter, which was finally lost because of Hitler's increasingly rigid control of the German army. And an army can never rely on surprise attacks to win most victories on the battlefield, whether it is the British or the Soviet army, as long as the formation is open, the German blitzkrieg is difficult to achieve. There were also fortresses like Brest or Sevastopol, where the Germans exposed their vast shortcomings in their offensive capabilities.
It is conceivable that if we had to wait a year to fight the Soviet Union, the German army would lose many days and places, the crisis of the Soviet Union's purge would gradually pass, the army's killed commanders and fighters would gradually make up, and the Soviet T-34 tanks would not be driven out of the factories one by one to refuel as they did during the Moscow defense war. Then, the Germans still had to rely on blitzkriegs against the Soviets. So, why wait? The fighters were fleeting, and if they waited another year, the Germans might not have the record of annihilating millions.
