MILITARY ORGANIZATION. The armed forces of a state are its government-sponsored defense and fighting forces and organizations used to further the objectives of the state. They exist to further the foreign and domestic policies of their governing body.
In some countries paramilitary forces are included in a nation's armed forces.
The military is divided into several services (also called branches).
The three most common are armies, navies, and air forces.
Some nations also organize their marines and their special forces as independent services.
In western militaries, a joint force is defined as a unit or formation comprising representation of combat power from two or more branches of the military.
It is common, at least in US and Commonwealth militaries, to refer to the building blocks of a military as units and formations.
Anything smaller than a unit is considered a "sub-unit" or "minor unit".
Formations include brigades, divisions, wings, etc.
In most navies a squadron is a formation of several ships; in most air forces it is a unit; in the U.S. Army it is a battalion-sized cavalry unit; and in Commonwealth armies a squadron is a company-sized sub-unit.
This gives an overview of some of the terms used to describe army hierarchy in armed forces across the world.
The following tables define the Symbol, Unit Name, number of personnel, number of subordinate units and the unit leader.
Naval organization at the flotilla level and higher is less-commonly abided by, as ships operate in smaller or larger groups in various situations that may change at a moment's notice.
These vessels include corvettes, gunboats, minesweepers, patrol boats, military riverine craft, tenders and torpedo boats.
Usually, the smaller the vessel, the lower the rank of the ship's commander.
Ships were collected in divisions, which in turn were collected in numbered squadrons, which comprised a numbered fleet.
Permission for a vessel to leave one unit and join another would have to be approved on paper.
The organizational structures of air forces vary between nations: some air forces (such as the United States Air Force and the Royal Air Force) are divided into commands, groups and squadrons; others (such as the Soviet Air Force) have an Army-style organizational structure.
Military rank is a system of hierarchical relationships in armed forces or civil institutions organized along military lines.
Usually, uniforms denote the bearer's rank by particular insignia affixed to the uniforms.
