Before and after World War II, the Soviet Union and Japan fought twice. The first time was the Battle of the Haraha River (Nomenkan Incident) in 1939. The second time was 1945 to help China destroy the Kwantung Army. In the Battle of the Haraha River, the Soviet army used zhukov and trusted him very much, as long as all the requirements favorable to the war were met. Use the latest BT tanks. In the battle, the Soviets concentrated on using tanks, infantry and aviation. For the first time, the use of deep combat in actual combat made people truly realize the power of tanks for the first time. The Japanese tank concept is still the concept of World War I, and they use auxiliary infantry in a decentralized way. Although tanks and infantry fight together, the Soviet army takes tanks as the main force of the army, and infantry auxiliary tanks destroy targets or infantry that enter the dead angle of tank shooting. However, Japan still takes infantry as the main force, so its March and deployment are very slow, far less than that of the Soviet Union. Therefore, it was a fiasco. The Soviet army wiped out more than 20,000 Japanese troops and captured tens of thousands of them at the cost of less than 1000 casualties. The second time, the Soviet army led by Marshal Aleksandr Aleksandr Aleksandr Aleksandr Vasilevsky launched a final attack on the Kwantung Army in the three northeastern provinces. At this time, the Soviet army experienced the baptism of the Soviet-German war, and the commander's strategy and tactics, individual combat ability, experience and cooperation between various services and arms were greatly improved compared with before the war. It can be said that it has reached the top level in the world, no less than the US military. However, the Japanese were dragged on by the people of China for eight years by guerrilla warfare, and their vitality was greatly damaged. There is nothing new in manpower and tactics. Only what Okamura Ningji used in the sweeping campaign of 194 1- 1942 will be used: dividing the war zone into several blocks with barbed wire and infantry trenches, and then blocking it with armored trains, turrets and various checkpoints. These are not in the eyes of the Soviet army at all. The stronger German defense lines have come, so I can't clean them up for days. Besides, you are wrong to say that the number of Japanese people exceeds that of Soviet troops. Moreover, the Soviet deployment is to fight Japan, which has nothing to do with population.
