Military organization

Military organization is the structuring of the armed forces of a ad hoc structures.

Military organisation is government department within the structure of public administration, often known as a Ministry of Defence, Department of Defence, or Department of War. These in turn manage Armed Services that themselves command combat, combat support and service support formations and units.

Executive control, management and administration

The usually civilian or partly civilian executive control over the national military organization is exercised in democracies by an elected political leader as a member of the government's Cabinet, usually known as a Minister of Defence. (In presidential systems, such as the United States, the president is the commander-in-chief, and the cabinet-level defense minister is second in command.) Subordinated to that position are often Secretaries for specific major operational divisions of the armed forces as a whole, such as those that provide general support services to the Armed Services, including their dependants.

Then there are the heads of specific departmental agencies responsible for the provision and management of specific skill- and knowledge-based service such as Strategy advice, Capability Development assessment, or Defence Science provision of research, and design and development of technologies. Within each departmental agency will be found administrative branches responsible for further agency business specialization work.

Armed services

In most countries the armed forces are divided into three or four Armed Services (also called branches): an army, a navy, and an air force.

Many countries have a variation on the standard model of three or four basic marines, special forces or strategic missile forces as independent armed services. A nation's coast guard may also be an independent military branch of its military, although in many nations the coast guard is a law enforcement or civil agency. A number of countries have no navy, for geographical reasons. Some other variations include:

In larger armed forces the culture between the different Armed Services of the armed forces can be quite different.

Most smaller countries have a single organization that encompasses all armed forces employed by the country in question. Third-world armies tend to consist primarily of infantry, while first-world armies tend to have larger units manning expensive equipment and only a fraction of personnel in infantry units.

It is worthwhile to make mention of the term joint. 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.

Internal security forces

Gendarmeries including equivalents such as Internal Troops, Paramilitary Forces and similar are an internal security service common in most of the world, but uncommon in Anglo-Saxon countries where civil police are employed to enforce the law, and there are tight restrictions on how the armed forces may be used to assist.[1]

Commands, formations, and units

In Japan, Lieutenant General J. Northcott CB MVO, Commander In Chief, British Commonwealth Occupation Force (BCOF), inspects the guard of honour at HQ 9th New Zealand Infantry Brigade ; April 17th 1946.

It is common, at least in the European and North American militaries, to refer to the building blocks of a military as commands, formations and units.

In a military context, a command is a collection of units and formations under the control of a single officer. Although during the Second World War a Command was also a name given to a battle group in the US Army, in general it is an administrative and executive strategic headquarters which is responsible to the national government or the national military headquarters. It is not uncommon for a nation's services to each consist of their own command (such as Land Component, Air Component, Naval Component, and Medical Component in the Belgian Army), but this does not preclude the existence of commands which are not service-based.

A formation is a composite military organization that includes a mixture of integrated and operationally attached sub-units, and is usually combat-capable. A formation is defined by the US Department of Defense as "two or more aircraft, ships, or units proceeding together under a commander".[2] Example of formations include: divisions, brigades, battalions, wings, etc. Formation may also refer to tactical formation, the physical arrangement or disposition of troops and weapons.[3] Examples of formation in such usage include: pakfront, panzerkeil, testudo formation, etc.

A typical unit is a homogeneous military organization (either combat, combat-support or non-combat in capability) that includes service personnel predominantly from a single arm of service, or a branch of service, and its administrative and command functions are self-contained. Any unit subordinate to another unit is considered its sub-unit or minor unit. It is not uncommon for unit and formation to be used synonymously, although formation is rarely used for small units like platoon or company. Other examples of units are: divisions, brigades, battalions, etc.

Different 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.

Table of organization and equipment

A table of organization and equipment (TOE or TO&E) is a document published by the U.S. Army Force Management Support Agency which prescribes the organization, manning, and equipage of units from divisional size and down, but also including the headquarters of Corps and Armies.

It also provides information on the mission and capabilities of a unit as well as the unit's current status. A general TOE is applicable to a type of unit (for instance, infantry) rather than a specific unit (the 3rd Infantry Division). In this way, all units of the same branch (such as Infantry) follow the same structural guidelines.

Modern hierarchy

Military organization
Typical Units Typical numbers Typical Commander
fireteam 3 or 4 corporal
squad/section 8 or more sergeant
platoon 15-30 lieutenant
company 80-150 captain/
battalion 300–800 lieutenant colonel
regiment/brigade 2,000–4,000 colonel/
brigadier general
division 10,000–15,000 major general
corps 20,000–40,000 lieutenant general
field army over 80,000 general
army group several
field armies
field marshal


The following table gives an overview of some of the terms used to describe army hierarchy in armed forces across the world. Whilst it is recognized that there are differences between armies of different nations, many are modeled on the British or American models, or both. However, many military units and formations go back in history for a long time, and were devised by various military thinkers throughout European history.

For example, Corps were first introduced in France in the 18th century, but have become integrated into the organization of most armies around the world. Readers interested in the detailed specifics of a national army (including the British and American) should consult the relevant entry for that country.

I infantry company, artillery battery, U.S. Cavalry troop, or Commonwealth armour or combat engineering squadron Sub Unit 80–250 2–8 platoons or Commonwealth troops chief warrant officer, captain or major
••• platoon or Commonwealth troop Sub-sub Unit 26–55 2+ squads, sections, or vehicles warrant officer, first or second lieutenant
•• section or patrol - 8–13 2+ fireteams corporal to sergeant
squad or crew - 8–13 2+ fireteams or 1+ cell corporal to staff sergeant
Ø fireteam - 4 n/a lance corporal to sergeant
Ø fire and manoeuvre team - 2 n/a any/private first class

Rungs may be skipped in this ladder: for example, typically NATO forces skip from battalion to brigade. Likewise, only large military powers may have organizations at the top levels and different armies and countries may also use traditional names, creating considerable confusion: for example, a British or Canadian armored regiment (battalion) is divided into squadrons (companies) and troops (platoons), whereas an American cavalry squadron (battalion) is divided into troops (companies) and platoons.

Army, army group, region, and theatre are all large formations that vary significantly between armed forces in size and hierarchy position. While divisions were the traditional level at which support elements (field artillery, hospital, logistics and maintenance, etc.) were added to the unit structure, since World War II, many brigades now have such support units, and since the 1980s, regiments also have been receiving support elements. A regiment with such support elements is called a regimental combat team in US military parlance, or a battle group in the UK and other forces.


  1. ^ In the United States it is a common misunderstanding that their armed forces are totally prohibited from doing so by the Posse Comitatus Act. This Act, which reserves to Congress the power to employ Federal military force to enforce law and order, refers specifically only to the US Army and US Air Force. The US Marines and Navy are separately regulated, and the Coast Guard has a clear law enforcement role in its peacetime status. The state-controlled Army National Guard (technically a branch of the US Army) is also excluded from the Posse Comitatus Act. The Insurrection Act specifically permits the President to use Federal military force to restore public order in extreme emergency situations: this Act was implemented during the "Rodney King Riots" in Los Angeles.

The organizational structures of air forces vary between nations: some air forces (such as the Royal Canadian Air Force uses Air Division as the formation between wings and the entire air command. Like the RAF, Canadian wings consist of squadrons.

Additionally, Naval organization continues aboard a single ship. The complement forms three or four departments (such as tactical and engineering), each of which has a number of divisions, followed by work centers.

The modern U.S. Navy is primarily based on a number of standard groupings of vessels, including the carrier strike group and the Expeditionary Strike Group.[7]

Historical navies were far more rigid in structure. 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.

Aircraft carriers are typically commanded by a captain. Submarines and destroyers are typically commanded by a captain or commander. Some destroyers, particularly smaller destroyers such as frigates (formerly known as destroyer escorts) are usually commanded by officers with the rank of commander. Auxiliary ships, including corvettes, gunboats, minesweepers, patrol boats, military riverine craft, tenders and torpedo boats are usually commanded by lieutenant-commanders or lieutenants. Usually, the smaller the vessel, the lower the rank of the ship's commander. For example, patrol boats are often commanded by ensigns, while frigates are rarely commanded by an officer below the rank of commander.

The five-star ranks of Admiral of the Fleet and Fleet Admiral have largely been out of use since the 1990s, with the exception of ceremonial or honorary appointments. Currently, all major navies are commanded by an admiral (four-star rank) or vice-admiral (three-star rank) depending on relative size. Smaller naval forces, such as the RNZN, or those navies that are effectively coastguards, are commanded by a rear-admiral, commodore or even a captain.

Flotilla or Task Unit Usually not capital ships A small number of vessels, usually of the same or similar types Rear Admiral (lower half), Commodore, or Flotilla Admiral
Task Element A single vessel One Captain or Commander

Navies are generally organized into groups for a specific purpose, usually strategic, and these organizational groupings appear and disappear frequently based on the conditions and demands placed upon a navy. This contrasts with army organization where units remain static, with the same men and equipment, over long periods of time.

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. However there is some common terminology used throughout navies to communicate the general concept of how many vessels might be in a unit.
