The army is composed of several divisions according to strategic needs, and there is no fixed establishment. Separation is more flexible. Usually from one brigade to one or two infantry brigades, a unit is temporarily set up from the unit for some tactical purpose. The detachment is usually named after the commander. For example, in the Battle of Taierzhuang, the detachment took the 33rd Infantry Regiment as the backbone, with four and a half brigades of infantry, but strengthened the 10 artillery and field artillery wing, the temporary field artillery squadron, the temporary mountain artillery brigade, the second field heavy artillery wing/1 brigade and a half wing, and the third team of China Artillery Regiment, except the chariot squadron and the engineering detachment.
Generally speaking, there are more infantry than brigades and more artillery than divisions. Sakamoto detachment is another protagonist in the Battle of Taierzhuang, consisting of six infantry brigades and three artillery squadrons. Compared with the detachment, there are more infantry and fewer artillery. In the battle of Taiyuan, the situation of Li Di detachment was even worse, with only two infantry squadrons. In addition, each squadron's machine guns, infantry and armored vehicles have been strengthened, with only one team or so. So the number of people in a team ranges from more than 10 thousand to thousands. Because departments are temporary organizations, natural institutions are not fixed.
In the Battle of Taierzhuang, the 1 brigade of the 39th Wing of the 8th Brigade of the/kloc-0 Division strengthened this detachment, and its strength increased by 1. During the campaign, Dick Division also strengthened two infantry squadrons. There are few records of Japanese and Chinese military forces in War of Resistance against Japanese Aggression. Mainly because the Japanese army is well-equipped and well-trained, it has great advantages compared with our army. Moreover, throughout War of Resistance against Japanese Aggression, the Japanese army always took the initiative, and most of them were launched by attack. Fang Zhouzi, even if the situation is unfavorable, he can retreat in time with the cooperation of friendly forces. Taierzhuang is an example. Therefore, it was easy to rebuild a Japanese army during the War of Resistance against Japanese Aggression period, but it was rarely wiped out.
