After Germany sneaked into Poland in the form of blitzkrieg, Britain and France declared war on Germany, and the Second World War officially began, although the British and French coalition forces had the courage to declare war, but the strength had a very large gap with the German army, less than a month by the German army occupied France, the coalition forces were forced to withdraw from Dunkirk France, began the passive defense stage.
Soviet-German relations
After Hitler's occupation of France, in addition to salivating at Britain across the sea, constantly launching attacks, but also began to plan to attack the Soviet Union, the Soviet Union at that time not only had a very large territory, but also very developed minerals and industry, if you can occupy the Soviet Union, then you can control the entire Eurasian plate in the hands of the Axis powers, becoming a springboard and supply station for their occupation of the world.
So Hitler held a number of secret military meetings to discuss how to attack the Soviet Union, after all, the strength of the Soviet army at that time was not weak, there were a large number of Soviet Red Army in the European border part, the result of the meeting was that Hitler believed that the combat effectiveness of the Soviet army was far inferior to that of the German army, so he brazenly launched an attack on the Soviet Union despite the dissuasion of the generals.
Blitzkrieg attacked the Soviet Union
The battle began as Hitler had predicted, the Soviet army was not vulnerable to the German "blitzkrieg", the defenses on the Western Front were quickly torn apart, the German army drove straight into the armored units and even advanced hundreds of kilometers a day, stalin was helpless in the face of Hitler's attack, and could only rely on the forced defense of the depleted troops.
Many Red Army soldiers were buried on the battlefield just after enlistment, which made the morale of the Soviet army very low, according to common sense, the military strength of the Soviet Union is not below Germany, why in the early stage of the battle will be defeated and retreat without the ability to fight back? The High Command made three big mistakes.
Hitler faked it
The first is to be confused by Hitler's smoke bombs, although the Soviets and Germany have been fighting swords for a long time, but after Hitler decided to attack the Soviet Union, it deliberately eased the contradictions between the two sides, so that Stalin relaxed his vigilance, believing that Hitler would not risk launching an attack on himself before occupying LinkedIn.
In the week before Hitler's panzer attack, British Prime Minister Winston Churchill and Soviet intelligence agents had told Stalin that Hitler was about to launch an offensive against the Soviet Union, but Stalin scoffed at it, thinking that these politicians were just alarmist, and Churchill, after learning the news, ruthlessly ridiculed Stalin for not having a vision, and said that the Soviet army would fail this time. However, Stalin still stubbornly believed that Hitler did not have the strength and courage to attack the Soviet Union, and as a result, he could only be defeated by Hitler's successful sneak attack.
German firepower
Secondly, the Soviet army's weapons and equipment lagged behind the German army, many Soviet troops at that time also held Mosingana sniper rifles handed down from the Tsarist era, although the range and sniper reduction of such weapons are quite good, but after all, it is difficult to cover the firepower, it is difficult to kill the enemy in pieces.
So the Soviet command soon sent someone to study a submachine gun that can be used in many conditions, and then the submachine gun was assembled into the Soviet army, of course, some excellent snipers have been using this sniper rifle with good range and accuracy, and shined on the battlefield, effectively improving the firepower of the Soviet army.
brief summary
Finally, the elite troops of the Soviet Army were near the Kwantung Army on the Eastern Front, because the Soviet Siberia was next to the Kwantung Army in the northeast, and they were the essence of the Soviet Army, but the Command Department did not want to transfer them to the Western Front at the beginning of the war, until the Battle of Stalingrad and the Battle of Leningrad, the Soviet Army did not give up the monitoring of the Japanese army.
