Formal military organization tends to use hierarchical forms (see Modern hierarchy for terminology and approximate troop strength per hierarchical unit).

Careers in the Army can extend into cross-functional areas for officers, warrant officers, enlisted, and civilian personnel. Before 1933,

In modern times, executive control, management and administration of military organization is typically undertaken by governments through a government department within the structure of public administration , often known as a ministry of defence or department of defense .

By November 1989 Pentagon briefers were laying out plans to reduce army end strength by 23%, from 750,000 to 580,000. A number of incentives such as early retirement were used. In 1990, Iraq invaded its smaller neighbor, Kuwait , and U.S. land forces quickly deployed to assure

In Commonwealth practice, formation is not used for smaller organizations such as battalions, which are instead called "units", and their constituent platoons or companies are referred to as sub-units. In the Commonwealth, formations are divisions, brigades, etc. Different armed forces , and even different branches of service of

After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.

Many countries have a variation on the standard model of three basic military branches. Some nations also organize their cyber force , emergencies service, medical service , military logistics , space force , marines , and special forces such as commandos or airborne forces as independent armed services.
