How big is an army group
A group army is a relatively large unit in a modern army, usually composed of several divisions, brigades, and various support units. Different countries and armies have different sizes and compositions of their army groups.
In the Chinese People's Liberation Army, a group army usually consists of three infantry divisions, one tank division, one artillery brigade, one engineer brigade and other support units, with a total strength of between 30,000 and 60,000. Among them, infantry divisions are the main combat force of the group army, and each infantry division usually has 9,000 to 12,000 people, including 3 infantry regiments, 1 artillery regiment, 1 tank regiment and 1 engineering regiment. Tank divisions usually have 3,000 to 5,000 men, including 3 tank regiments and 1 engineering regiment. Artillery brigades usually have 2,000 to 3,000 men, including 3 artillery regiments and 1 engineering regiment. Engineer brigades usually have 1,500 to 2,500 men, including three engineer regiments and one transport regiment. In addition, the group army may also include other support units, such as the chemical defense regiment, the guard regiment, the military affairs office, the finance office, the military hospital, etc.
In Western countries, the size and composition of army groups also differed. For example, the U.S. Army's army group usually consists of several divisions, brigades, and various support units, with a total strength of between 80,000 and 150,000 troops. Of these, each division usually has 150,000 to 20,000 people, including 3 brigades, 1 engineer brigade, 1 artillery brigade, 1 armored brigade, etc. In addition, the army group may also include other support units, such as aviation brigades, communications brigades, gendarmerie, etc.
In short, the size of an army group usually ranges from tens of thousands to hundreds of thousands of people, and the specific size and composition vary from country to country and army to army.
