How do I call the department or division which consisted 100 of policemen or troops?

Answer 1

Usually a company is closest to that figure (Infantry) but it depends on the type of unit. A company is usually divided into three or four platoons

Answer 2

A Army or Marine company will comprise of anywhere from 100-200 soldiers. However, this number will change drastically based on the mission of that unit. In the Air Force, this could be considered a Flight or a Squadron. Once again, it depends on the make up of the unit. A Security Forces Squadron might consist of 100 Airman, while a Maintenance Squadron could consist of 400+. Another term that could possible be used is a detachment, though this is normally a section of troops broken off from a larger unit.

When talking about police, a unit size will varry from city to city and state to state.

Without knowing the content of how you plan on using this information, your safest assumption would be to say a 'Company'. That being used in the modern sense and refering to a US Army or Marine unit.

Companys.

Battalions. or Regiments.

The number of men in each would vary depending on the Country it is in. Peace time or War time footing.

In modern times there is no such distinction. The closest thing would be a company. However; in Roman times this was called a "century". A Centurion was in charge of 100 men....or a century.
