There are great differences among regiments, brigades, divisions and armies in different countries, which are determined by their different strategies, tactics and operational purposes. As for battalion platoon, there is also a big difference; Let's talk about the army first. Every country is different, and different armies in the same country are not fixed, because it is necessary to make preparations and supplement the combat tasks of supporting troops. For example, China's 38th Army is said to have 86,000 people, while the 27th Army is said to have only 25,000 people. The US 18 Airborne Force has 90,000 troops, and the 3 rd and 5 th Army basically has 40,000-50,000 troops. In wartime, these two armies will increase their strength by 1.5 million; In wartime, an army in France is generally 55,000, and an army in Germany is more than10,000. The northern team of the Japanese army is equivalent to an army, with only 50 thousand people; According to the establishment, the Russian army will reach about 50,000 people in wartime, like the United States, and the army will generally reach156,000 people in wartime (taking the following three divisions as an example). Divisions are also divided into light and heavy divisions, 1.68 million armored divisions,1.70 million mechanized divisions,1.30 million airborne divisions and 65438+ light infantry divisions. There are about four or five thousand people in each brigade; The United States has the largest number of marine divisions in the world, with 1.8 million before strengthening, and Japan has the least 1 division, with only 6,600. Russian tank division 1. 1.6 million, motorized infantry division 1.35 million. Its group army has four divisions according to regulations, with less than 80 thousand people (of course, it will be supplemented in wartime); What is the difference? The difference between groups is even greater. Among the combat regiments, the Indian infantry division, not the tank regiment, has the smallest number of 700 people. The American Independent Armored Cavalry Corps has about 3,200 people; Let's not talk about battalion companies, let's talk about classes first. The number of infantry classes is not fixed, and countries will decide according to their own conditions, firepower, support capacity and task requirements. Generally speaking, there are 10 infantry classes in China, instead of the nine recorded in 1998 February edition of Weapons Knowledge. Armored infantry squad 1 1 (including 3 people on board). There are 9 infantry classes and mechanized infantry classes in the United States, with the most infantry classes on land,13; The smallest infantry squad is British, with 7 people; I won't say the details. In a word, the establishment of the army is related to the combat capability and even to the victory or defeat of the war. The number of troops in various countries is determined after careful study. We must never mechanically apply the 33- system and the 44- system. The problem of military establishment is much more complicated than weapons. I hope the friends above will pay attention to this when answering such questions. Thank you!
