The Japanese aggressors' individual equipment is much better than that of the national army. In the national army, only the armored division and the equipment of American mechanics can compete with the Japanese aggressors, even better than them. The equipment of the Eighth Route Army, the New Fourth Army, the Sichuan Army, the Yunnan Army and the Cui Jinjun is far less than that of the Japanese aggressors. It's hard to have a rifle, let alone a military backpack. After all, the number of armored troops in the national army is too small, and most of them are poorly equipped. It's hard to see one with a military backpack. Most armored soldiers died in the Battle of Songhu, and most elite soldiers were annihilated by the Japanese invaders in the Battle of Nanjing. In other words, the well-equipped armies of various countries were wiped out in the early days of the Anti-Japanese War, and it was difficult to see the armies of various countries equipped with military backpacks in the late days of the Anti-Japanese War.
The equipment of an army is closely related to the economic base of the country. As an industrial power, Japan plundered the resources of China and other countries, so its equipment was better. As a poor and weak agricultural country, China has a weak industrial base and very low productivity, and a lot of equipment has to be imported, which is not enough to equip a large number of troops.
During the War of Resistance against Japanese Aggression period, China was still in a state of warlord separatism. Although warlords all over the country are unanimous in resisting Japan, most of the equipment, supplies, military salaries and meals must be self-sufficient, and the government's financial resources are limited and focused, so it cannot take care of all the troops. The bayonet is such a simple weapon that the national army cannot install it in the whole army, mainly relying on imported bayonets; The national army uses cold weapons such as broadswords and spears.
