The structure of the
North Atlantic Treaty Organization
The North Atlantic Treaty Organization (NATO ; , OTAN), also called the North Atlantic Alliance, is an intergovernmental transnational military alliance of 32 member states—30 European and 2 North American. Established in the aftermat ...
(NATO) is complex and multi-faceted. The decision-making body is the
North Atlantic Council (NAC), and the member state representatives also sit on the
Defence Policy and Planning Committee (DPPC) and the
Nuclear Planning Group (NPG). Below that the
Secretary General of NATO directs the civilian
International Staff, that is divided into administrative divisions, offices and other organizations. Also responsible to the NAC, DPPC, and NPG are a host of committees that supervise the various NATO logistics and standardisation agencies.
The
NATO Military Committee
The NATO, North Atlantic Treaty Organization (NATO)'s Military Committee (MC) is the body that is composed of Member states of NATO, member states' Chief of Defence, Chiefs of Defence (CHOD). These national CHODs are regularly represented in the M ...
advises and assists the NAC on military matters. The Defence Planning Committee which directs its output to the Division of Defence Policy and Planning, a nominally civilian department that works closely with the Military Committee's
International Military Staff.
All agencies and organizations are integrated into either the civilian administrative or military executive roles. For the most part they perform roles and functions that directly or indirectly support the security role of the alliance as a whole.
History

The DPC was a former senior decision-making body on matters relating to the integrated military structure of the Alliance. It was dissolved following a major committee review in June 2010 under Secretary-General
Anders Fogh Rasmussen. Its responsibilities absorbed by the
North Atlantic Council and the
Defence Policy and Planning Committee (DPPC).
Civilian structure
In ''NATO: The First Five Years'',
Lord Ismay described the civilian structure as follows:
The ..Office of the Secretary General sdirected by an Executive Secretary, Captain R.D. Coleridge (UK), who is also Secretary to the Council. He is responsible for supervising the general processing of the work of the Council and their committees, including provision of all secretarial assistance, as well as supervision of the administrative services of the Staff/Secretariat itself. Thus the Secretariat provides secretaries to all the Council's principal committees and working groups - apart from those of a strictly technical nature - and ensures co-ordination between them. .. On the Staff side there are three main divisions corresponding to the three principal aspects of NATO's work, each under an Assistant Secretary General. Ambassador Sergio Fenoaltea (Italy) heads the Political Affairs Division, M. Rene Sergent (France) the Economics and Finance Division, and Mr. Lowell P. Weicker (USA) the Production and Logistics Division. The Divisions' tasks are to prepare, in close touch with delegations, proposed action in their respective fields for consideration by the appropriate committee or by the Council. In addition to the main divisions there are three other offices working directly to the Secretary General. These are the Office of Statistics (Mr. Loring Wood of the USA), the Financial Comptroller's Office (M. A. J. Bastin of Belgium), and the Division of Information (Mr. Geoffrey Parsons, Jr. of the USA). The Information Division, besides providing material about NATO for the use of member governments, (it does not engage in independent operations), is also the press and public relations branch of the civilian authority.
Military structure
The Strategic Commanders are the former 'Major NATO Commanders', who sat atop a command hierarchy consisting of Major Subordinate Commanders (MSCs), Principal Subordinate Commanders (PSCs) and Sub-PSCs. The Military Committee had an executive body, the Standing Group, made up of representatives from France, the United States, and the United Kingdom. The Standing Group was abolished during the major reform of 1967 that resulted from France's departure from the NATO Military Command Structure.

Evolution of NATO's Command Structure 1951-2009
.
Beginnings
A key step in establishing the NATO Command Structure was the North Atlantic Council's selection of General
Dwight D. Eisenhower as the first
Supreme Allied Commander Europe (SACEUR) in December 1950.
After Eisenhower arrived in Paris in January 1951, he and the other members of the multinational
Supreme Headquarters Allied Powers Europe

(SHAPE) Planning Group immediately began to devise a structure for the new Allied Command Europe. NATO official documents say '..The corner stone of the NATO Military Command Structure was laid.. when the North Atlantic Council approved D.C. 24/3 on 18 December 1951.' They quickly decided to divide Allied Command Europe into three regions:
Allied Forces Northern Europe, containing Scandinavia, the North Sea and the Baltic;
Allied Forces Central Europe, and
Allied Forces Southern Europe (AFSOUTH), covering Italy and the Mediterranean. SHAPE was established at
Rocquencourt, west of Paris.
The British post of Commander in Chief
Mediterranean Fleet was given a dual-hatted role as

Commander in Chief of
Allied Forces Mediterranean in charge of all forces assigned to NATO in the Mediterranean Area. The British made strong representations in discussions regarding the Mediterranean NATO command structure, wishing to retain their direction of NATO naval command in the Mediterranean to protect their
sea lines of communication running through the Mediterranean to the Middle East and Far East.
In 1952, after Greece and Turkey joined the Alliance,
Allied Land Forces South-Eastern Europe
The Allied Land Command (LANDCOM), formerly Allied Land Forces South-Eastern Europe (LANDSOUTHEAST), is the standing Staff (military), headquarters for NATO land forces which may be assigned as necessary. The Commander of LANDCOM is the primary Gr ...
(LANDSOUTHEAST) was created in Izmir, Turkey, under a U.S. Army General.
This was due to the two states' geographic distance from the LANDSOUTH headquarters, as well as disagreements over which nation should be the overall commander for their ground forces.

With the establishment of
Allied Command Atlantic (ACLANT) on 30 January 1952, the
Supreme Allied Commander Atlantic joined the previously created
Supreme Allied Commander Europe as one of the alliance's two Major NATO Commanders. A third was added when
Allied Command Channel was established on 21 February 1952 to control the
English Channel

area and deny it to the enemy, and protect the sea lanes of communication. The establishment of this post, and the agreement that it was to be filled by the British
Commander-in-Chief, Portsmouth, was part of the compromise that allowed an American officer to take up the SACLANT post. Previously Commander-in-Chief Portsmouth had controlled multinational naval operations in the area under
WUDO auspices. In due course the CINCHAN role was assumed by the British
Commander-in-Chief Fleet.

After the Cold War
By June 1991, it was clear that Allied Forces Central Europe (a Major Subordinate Command) could be reduced, with the Soviet threat disappearing. Six multinational corps were to replace the previous eight. Announcements in June 1991 presaged main defensive forces consisting of six multinational corps. Two were to be under German command, one with a U.S. division, one under Belgian command with a pending offer of a U.S. brigade, one under U.S. command with a German division, one under joint German-Danish command (LANDJUT), and one under Dutch command. The new German
IV Corps was to be stationed in Eastern Germany, and was not to be associated with the NATO structure.
On 1 July 1994, the Alliance disestablished
Allied Command Channel, through retaining many of its subordinate structures after reshuffling. Most of the headquarters were absorbed within ACE, particularly within the new
Allied Forces Northwestern Europe.

From 1994 to 1999 ACE had three Major Subordinate Commands, AFNORTHWEST, AFCENT, and AFSOUTH. In 1995 NATO began a Long Term Study to examine post-Cold War strategy and structure. Recommendations from the study for a new, streamlined structure emerged in 1996. The European and Atlantic commands were to be retained, but the number of major commands in Europe was to be cut from three to two, Regional Command North Europe and Regional Command South Europe. Activation of the new RC SOUTH occurred in September 1999, and in March 2000 Headquarters AFNORTHWEST closed and the new RC NORTH was activated. The headquarters of the two Regional Commands were known as Regional Headquarters South (RHQ South) and RHQ NORTH respectively. Each was to supervise air, naval, and land commands for their region as well as a number of Joint Subregional Commands (JSRCs). Among the new JSRCs was
Joint Headquarters Southwest, which was activated in Madrid in September 1999.

(ACT) responsible for the induction of the new member states' forces into NATO, and NATO forces' research and training capability. The European allies had become concerned about the possibility of a loosening of U.S. ties to NATO if there were no longer any U.S.-led NATO HQ in the United States, and the refocusing of the Atlantic command into a transformation command was the result. The alliance created several NATO Rapid Deployable Corps and naval
High Readiness Forces (HRFs), which all report to Allied Command Operations. In Europe the Regional Commands were replaced by JFC Brunssum and JFC Naples, and the JSRCs disappeared (though the Madrid JSRC became a land command for JFC Naples).
The commander of Allied Command Operations retained the title "
Supreme Allied Commander Europe", and remains based at SHAPE at Casteau. He is a U.S. four-star general or admiral with the dual-hatted role of heading

, and that a new
Multinational Division Southeast would be established in Romania. Six
NATO Force Integration Units would also be established to coordinate preparations for defence of new Eastern members of NATO.
Multinational Division Southeast was activated on 1 December 2015. Headquarters Multinational Division South – East (HQ MND-SE) is a North Atlantic Council (NAC) activated NATO military body under operational command (OPCOM) of Supreme Allied Commander Europe (SACEUR) which may be employed and deployed in peacetime, crisis and operations.
On 25 April 2017, the commander-designate of the new
Multinational Division Northeast arrived at the headquarters location at
Elblag, Poland. On 3 July 2017, the new division reached
initial operational capability (IOC). The division is tasked to coordinate the four
NATO Enhanced Forward Presence battlegroups and to carry out
Article 5 collective defence activities.
In late 2017-early 2018, two new commands were approved, a rear area transit command which was finally announced as the
Joint Support and Enabling Command, to be located at
Ulm, Germany, and a new command for the Atlantic. In March 2018 Chair of the Military Committee General
Petr Pavel announced that the new Atlantic command would become part of the NATO Command Structure at the level of a Joint Force Command, similar to the two that exist at
Brunssum and Naples. On 7 June 2018 the Secretary-General said the new joint forces command will have its headquarters in Norfolk, Virginia, in the United States. The name was confirmed as
Joint Force Command Norfolk at the NATO Summit in July. It was to be commanded by the
vice-admiral who leads the
United States Second Fleet. On 15 July 2021 Joint Force Command Norfolk (JFC-NF) attained Full operational capability (FOC) under the command of Vice Admiral Andrew Lewis.
Canada-US Regional Planning Group
The Canada-US Regional Planning Group (CUSRPG) is the only survivor of the originally five regional planning groups of the late 1940s and early 1950s. All the others were subsumed into
Allied Command Europe and
Allied Command Atlantic. In August 1953 it was tasked to '..(a) Prepare, approve and forward to the Military Committee, through the Standing Group, plans for and other material pertaining to, the defense of the Canada-U.S. Region. (b) Coordinate plans with SACLANT and other NATO Commands. The NATO Handbook stated in 1990s editions that it was responsible for the defence of the US-Canada area and meets alternatively in

Crisis Response Operations in NATO Operating Systems (CRONOS), which is a system of interconnected computer networks used by NATO to transmit
classified information
Classified information is confidential material that a government deems to be sensitive information which must be protected from unauthorized disclosure that requires special handling and dissemination controls. Access is restricted by law or ...

Organizations and agencies
A major reorganization of the NATO Agencies was agreed at a meeting of the defence ministers from NATO's 28 member states on 8 June 2011. The new Agencies' structure would be built upon the existing one:
Jorge Benitez, "Details of NATO's new agency structure"
, ''NATO Source'', 9 June 2011. Retrieved 10 June 2011.
*Headquarters for the NATO Support Agency would be in Capellen Luxembourg (site of the NATO Maintenance and Supply Agency – NAMSA).
*The NATO Communications and Information Agency Headquarters would be in Brussels, as would be the very small staff which will design the new NATO Procurement Agency.
*A new NATO Science and Technology Organization (STO) would be created before July 2012, consisting of Chief Scientist (located in the Office of the Chief Scientist, OCS), a Programme Office for Collaborative S&T (the Collaboration Support Office, CSO), and the Centre for Maritime Research and Experimentation (CMRE, previously named the NATO Undersea Research Centre).
*The current NATO Standardization Agency would continue and be subject to review by Spring 2014.

Often taken for granted, the Alliance's integrated command structure provides the basis for NATO's collective defense, and increasingly, as seen in Bosnia, its ability to undertake peace support operations. However, the very value by which nations hold the structure has resulted in a difficult and time-consuming reorganization process, which has produced only limited reforms.

Reduced national force structures, new NATO roles and missions emanating from the military implementation of Alliance Strategy and the rapid reaction requirements associated with the embryonic Combined Joint Task Forces (CJTF) concept are but three of a multitude of inter-related issues.
