In the early morning of June 22, 1941, in order to fulfill its dream of "global domination", Nazi Germany launched a fierce attack on the Soviet Union, which was then across the Eurasian continent, with aircraft bombing to retreat from the enemy, tanks to open the way, and infantry to rapidly advance.
Due to the unexpected attack on the Germans, the Soviet Union suffered successive heavy losses in the early stages of the war. On the first day of the battle alone, the Soviet Air Force lost 1,200 aircraft, and the air supremacy over the Soviet Union fell into German hands, and in their own skies, the Soviets also began to be careful of bombs.
The most tragic battle was the Su-German Battle of Kiev in September 1941, in which the main force of the Soviet Southwestern Front was trapped in Kiev by the German army due to the order to die in Kiev, which eventually caused the tragedy of 660,000 Soviet troops being annihilated.
Similar to the Great Victory of the German Army in Kiev, in the early days of the Soviet-German War, it blossomed everywhere on the land of the Soviet Union, and if millions of Soviet troops were not completely counted, they were either killed or captured, or they lost their combat effectiveness. Because of this, German soldiers could march on the Soviet capital, Moscow, in November 1941, where they sharpened their knives to destroy the Soviet state.
According to normal inference, the Soviets lost millions of troops in the early stages of the battle, and should fall into a state of collapse, after all, a country can organize a million troops, it is already very remarkable.
Even Germany, as an all-out offensive party, only reached about 5.5 million troops in the Soviet Union, with the support of some allies.
However, to the surprise of all germans, the Soviets they encountered were not recognized by "common sense", everyone thought that the Soviet Union had broken its bones, and what was left was when Germany was harvesting the spoils of war, and on December 6, 1941, the Soviet Union suddenly concentrated millions of troops and launched a counterattack on the front line in Moscow.
Not only did it break the German siege of Moscow, but it also drove the invincible German soldiers 200-300 kilometers, turning the direct situation on the battlefield from the Soviet Union's blind passive beating to a stalemate in which the Soviet Union and Germany won and lost.
It was precisely because of the sudden appearance of a large number of military forces in the Soviet Union that the German soldiers who were fighting in the forefront of the battle sent out a sigh of how the Soviet soldier fought more and more, and when was the head.
As for why the Soviets were able to replenish their forces quickly? First of all, the human base of the Soviet union is not bad, the Soviet union population of 130 million in 1917, the Population of the Soviet Union in 1940 is 194 million, in the 23 years before the start of World War II in 1941, the Soviet Union had a peak of 64 million population growth, and this means that at the moment of the start of World War II, the Soviet Union was tens of millions of young adults.
After modern warfare entered the era of firearms, it was difficult to get weapons on hand, unlike the ancient times, with kitchen knives that could be used on the battlefield, so with a source of soldiers, there was no suitable training, and it was difficult to supply a large number of qualified soldiers.
Fortunately, the Soviet Union formulated a perfect military service system before the war began, and not only did it specify that at the age of 18, it could enter the army.
From the ninth grade onwards, Soviets received primary military education in schools, and this training gave every Soviet a certain understanding of weapons. When you really want to go to the battlefield to defend your family and defend your country, you don't know how to fight with a gun.
It is precisely because almost all people have a certain military quality that this greatly shortens the time for Soviet soldiers, from recruitment to combat, which is undoubtedly the basis for the Continuous Supply of Soldiers by the Soviet Union to the front line.
