The order of units in the army from largest to smallest is usually as follows: corps, divisions, brigades, regiments, battalions, companies, platoons, and squads. Therefore, the order of regiments, divisions, brigades, and companies is: regiments> divisions> brigades, and > companies.
This order did not begin with a single country, but gradually formed in a number of countries with the development of military technology and the form of warfare.
In early wars, armies were usually organized and commanded on the basis of numbers, but with the development of firearms and the expansion of the scale of warfare, the organization and command structure of armies gradually became more complex.
In the 18th century, European countries began to establish standing armies, implemented a unified conscription system, and gradually formed a system of divisions, brigades, regiments, battalions, companies, platoons, and squads.
In China, during the New Deal period at the end of the Qing Dynasty, in 1905, Yuan Shikai reported to the Qing court, proposing to unify the provinces and build a new army number.
The titles of the army at all levels are: town-association-standard-battalion-team-sentry-shed, corresponding to the division, brigade, regiment, battalion, and company platoon, and each province has its own town for training the new army. Each town imitates the Japanese army divisions, with a total of 20 battalions of infantry, horses, artillery, engineers, and baggage, with a total of 12,512 people.
Standard Establishment of Towns at the End of the Qing Dynasty: The original "Standing Army of XXX Province" was renamed "Army XX (Province) Town X", or "XX Mixed Association".
During the ** period, the establishment of the brigade basically did not change much, and it generally governed 2 and 3 regiments, and the brigade commander was usually a major general. However, due to the chaotic and frequent changes in the establishment system of the army during the ** period, the names of brigades and divisions were used alternately.
In August 1945, the Military Commission issued the "Decision on the Present Establishment of Troops", instructing all strategic areas to form field corps and local corps. The field corps implements the establishment sequence of columns, brigades (divisions), regiments, battalions, companies, platoons, and squads, with columns organized into 3-5 brigades, and from brigades to companies, they are organized according to the "three-three system", but each platoon is organized into 4 squads (3 rifle squads and 1 firepower squad).
In November 1948, the Military Commission decided to reorganize the whole army, stipulating that the whole army should be divided into field troops, local troops, and guerrilla units. The columns of the field troops were renamed corps, and there were two levels of corps and field army at and above the army level, and the army and below were generally organized according to the "three-three system," and the original brigades were all changed to divisions.
The troops in ancient China were also arranged in a certain sequence.
During the Shang Dynasty, the establishment of troops basically followed the "eight formations" method of the Yellow Emperor era, with chariots as the basic unit, and each chariot was equipped with two armor soldiers, one warrior and one archer.
At the same time, the Shang Dynasty also established a large-scale infantry army, which was mainly divided into four parts: the forward, the left wing, the right wing, and the rear wing.
By the time of the Zhou Dynasty, the establishment of the army had undergone great changes. Zhou Gongdan established the "Six Armies" system, that is, the Guards under the direct command of the royal family and the directly subordinate troops established by the six major vassal states.
Among them, the Royal Janissary was divided into two parts: the Southern Army and the Northern Army. The Southern Army was responsible for guarding the royal fortress, and the Northern Army was responsible for guarding the Gyeonggi region.
The direct subordinate troops established by the six major vassal states were called the "Six Divisions", and each division had a strength of about 2,500 men. During the Qin Dynasty, the establishment of the army changed again.
After Qin Shi Huang unified the Six Kingdoms, he divided the country into a number of provinces, each of which had a general who was responsible for commanding the local army. At the same time, the Qin Dynasty also established a large number of infantry and cavalry teams, of which the infantry was divided into two types: light infantry and heavy infantry, and cavalry was divided into two types: cavalry archers and heavy cavalry.
During the Han Dynasty, the establishment of troops basically followed the system of the Qin Dynasty. During the period of Emperor Wu of the Han Dynasty, the centralization of power was vigorously strengthened and a more perfect military system was established.
The army of the Han Dynasty was divided into two types: the ** army and the local army, which was directly commanded by the emperor and was divided into two parts: the Beijing division and the border army. The local army is under the jurisdiction of the local ** and is mainly responsible for local security and defense.
During the Tang Dynasty, the establishment of the army underwent great changes. The Tang Dynasty established the "government military system", which divided the country into several military regions, each of which set up a governor's office to lead the local army. At the same time, the Tang Dynasty also established a large-scale cavalry corps, which was mainly divided into two types: light cavalry and heavy cavalry. In addition, the Tang Dynasty also established the "Shence Army" as the emperor's guard, responsible for guarding the palace and the emperor's safety.
During the Song Dynasty, the establishment of the army basically followed the system of the Tang Dynasty. The Song Dynasty implemented the "forbidden military system", dividing the country into several forbidden military camps, and each battalion set up a commander to be responsible for commanding the local army. At the same time, the Song Dynasty also established a large-scale infantry corps, which were mainly divided into forwards, infantry, crossbowmen and gunners. In addition, the Song Dynasty also set up special forces such as naval forces and engineers.
During the Ming Dynasty, the establishment of the army underwent great changes. The Ming Dynasty implemented the "guard system", dividing the country into several guard posts, each of which set up a commander to lead the local army. At the same time, the Ming Dynasty also established large-scale infantry and cavalry teams, of which the infantry was divided into pikemen, sword players, archers, etc., and the cavalry was divided into light cavalry and heavy cavalry. In addition, the Ming Dynasty also set up special forces such as sailors and engineers.
Therefore, it can be concluded that the troops in ancient China were also arranged according to a certain sequence, including different arms such as chariots, infantry, and cavalry, as well as different formations and command systems. With the development of history and the changes in the form of warfare, the establishment and sequence of the armed forces have also undergone many changes and improvements.
