The former Japanese army, with more than 10,000 troops, crushed hundreds of thousands of Qing dynasty navies, forced the Qing court to sign a traitorous treaty, and then the Japanese army occupied the vast northeast with almost no consumption of troops, even if our country was fully engaged in this war against Japan, the Japanese army killed only about half a million, paying the lives of millions of soldiers.
But in the face of the Soviet army, this Japanese army seems to have passed, losing most of its troops in just ten days, why did they behave so heroically when they fought our country, but they were defeated so easily in the face of the Soviet army.

In fact, it is not that the combat effectiveness of our soldiers is poor, but that the Soviet army has a huge advantage. Japan is a very small island country, the population of this country has been small, when attacking the mainland, it also excavated almost all the strength of the country to mobilize young people of the right age to participate in the war, many people were forced into the army when they were not yet young, and some were forced into the army when they were sixty or seventy.
In fact, in terms of combat effectiveness, the gap between the various departments is still huge, and the most elite unit of the Japanese army is naturally the Kwantung Army, and it is also this army that gallops at will on the battlefield of our country, almost destroying most of china's defense areas, occupying countless resources, and pulling up a huge number of puppet armies.
Although the Japanese army occupied a great advantage in the early stage of the War of Resistance Against Japanese Aggression, after the middle period, the Chinese army began to change, no longer as in the past to be defeated at will, although the Chinese army has no small defects in weaponry, equipment and logistics, but at this time the Japanese army has no such advantage as the beginning, and the Chinese army is slowly rising.
In particular, the Japanese army also divided its troops to fight, in addition to the Chinese battlefield they also divided the troops in the Pacific, Southeast Asia, which also directly led to the serious shortage of Japanese troops in various theaters, and although the number of puppet troops is huge, it is not qualified to truly replace the elite of the Japanese army.
When the Soviet Union sent troops to the northeast, the Japanese army had lost its former glory, the combat strength of each line was tight, no matter which direction it was already at a disadvantage, as if it was about to be defeated soon, and the Kwantung Army, which was known as a million in the northeast, was only a miscellaneous army, and there was a huge defect in combat effectiveness.
Although the northeast region is still a serious Japanese soldier, but it is a group of insufficient Combat Strength of the Japanese Army, it is impossible to pose any threat to the Soviet Union, at this time Japan was jointly sanctioned by major countries, there was a great shortage of materials, there was simply not enough money to equip the army with better equipment.
The Japanese army in the northeast was significantly inferior to the Soviet army in terms of combat effectiveness, and this was still an army of uneven age, and the Soviet Union had just crushed the German army, which was at its strongest, and under the rapid attack of the Soviet Union, the Japanese army was crushed by most of them before they could react.
Whether it is combat strength or command ability, the Northeast Army at this time is obviously weaker than the Soviet army, let their elite troops to fight OK, these miscellaneous troops are absolutely not strong against the strong Soviet army, which is also the reason why the Japanese army was quickly crushed.
