Because it is convenient and intuitive to remember the allocation of troops, the old man has made a tidy up

Army, division, brigade, regiment, battalion, company, platoon, and squad are all in the three-tier system

Class = 10 people

Platoon = 30 people

Company = 100 people have: Scout squad

Battalion = 300 people

Regiment = 1000 people have: reconnaissance company

Brigade = 3000 people

Division = 10,000 people have: direct regiment

Army = 30,000 people
