During World War II, both the Soviet Union and the United States fought against Japan, but the performance of the two countries was very different. The Soviets, starting from the earliest Battle of Nomonkan and finally sending troops to the northeast to deal with the Japanese Kwantung Army, almost all of them had an overwhelming advantage. On the other hand, the US army is different, and in the confrontation with the Japanese army, it can be said that it has paid a huge price.
By the end of World War II, the Soviet Union and the United States had become superpowers, and the military strength of the two countries had been equal for a long time. This makes people wonder, if this is the case, then why is it that the US army and the Japanese army are fighting very hard, while the Soviet army is destroying the Kwantung Army?
The metamorphosis of the Soviet Army
In fact, at the beginning of World War II, the combat effectiveness of the Soviet army was not only not strong, but even described as bad, when the Soviet Union sent millions of troops to attack Finland, and the result was a crushing victory. The Soviet army was able to complete the metamorphosis, mainly stimulated by the Soviet-German war, and they slowly became stronger through years of fighting with the powerful Germany.
Moreover, with the soviet union's defeat of Germany with the help of the Allies, the Soviet army not only gained momentum, but also captured a lot of weapons and equipment. Under such circumstances, it is simply a matter of hand to deal with a group of "old, weak and disabled soldiers", and this group of "old and weak and disabled soldiers" is also the Japanese ace unit Kwantung Army that the Soviet Union encountered in the northeast at the end of World War II.
The Kwantung Army plummeted in strength
All this stemmed from the fact that since the outbreak of the Pacific War, with the exception of some old and weak soldiers, Japan has sent almost all the elite of the Kwantung Army to the Pacific. Subsequently, in order to replenish the strength of the Kwantung Army, the Japanese did not even spare some elderly people and children, and it was obvious that such a low combat effectiveness and greatly affected morale could be a Soviet opponent.
On the contrary, the Japanese troops encountered by the US military in the Pacific were almost all elite. Moreover, because Japan occupied many Pacific islands long ago, they are more familiar with the surrounding environment, and it is true that the US military has the advantage of equipment and logistical supplies, but in the face of the Japanese army with rich combat experience and not being afraid of death, it is understandable that the "young master soldiers" fought very hard.
Young Master Soldier
It is worth mentioning that before the Japanese attack on Pearl Harbor in World War II, most of the American soldiers had not really been on the battlefield, a group of recruits who stayed in the greenhouse for a long time, they naturally needed to pay countless blood and lives to transform, so the Japanese army taught them a good lesson. However, multi-front operations coupled with the lack of resources have long put Japan at the end of the crossbow, so it is expected that the United States will win the war in the end.
In short, the reason for this difference is completely disturbed by many external factors, so there is not much value in comparing the strength and weakness of the Soviet army and the American army. Moreover, the strength of the Japanese army in World War II is beyond doubt, so no country that can defeat the Japanese army is not strong.
