Military Command Structure

Allied Command Operations (ACO) is a three-tier command with headquarters and supporting elements at the strategic, operational and tactical level. It exercises command and control of static and deployable headquarters, as well as joint and combined forces across the full range of the Alliance's military missions. Joint forces are forces from two or more military departments working under a single command and combined forces are forces from different countries working under a single command.

SHAPE, at the strategic level, is at the head of six operational commands, two of which are supported by tactical (or component) level entities.

Allied Command Operations

There are three tiers of command: strategic, operational, and the tactical level. The command structure is based on functionality rather than geography.

SHAPE is a strategic headquarters. Its role is to prepare, plan, conduct and execute NATO military operations, missions and tasks in order to achieve the strategic objectives of the Alliance. As such it contributes to the deterrence of aggression and the preservation of peace, security and the territorial integrity of Alliance.
ACO is headed by SACEUR, who exercises his responsibilities from SHAPE. Traditionally, he is a United States Flag or General officer. SACEUR is dual-hatted as the commander of the US European Command, which shares many of the same geographical responsibilities. SACEUR is responsible to the Military Committee, which is the senior military authority in NATO under the overall political authority of the North Atlantic Council (NAC) and the Nuclear Planning Group (NPG). The Military Committee is the primary source of military advice to the NAC and NPG.

Operational Level Commands: Brunssum, Naples and Norfolk

jfc%20brunssumThe operational level consists of three standing Joint Force Commands (JFCs): one in Brunssum, The Netherlands, one in Naples, Italy and one in Norfolk, Virginia. All have to be prepared to plan, conduct and sustain NATO operations of different size and scope. Effectively, they need to be able to manage a major joint operation either from their static location or from a deployed headquarters when operating directly in a theatre of operation. In the latter case, the deployed headquarter is referred to as a Joint Task Force HQ or JTFHQ and should be able to operate for a period of up to one year.

When deployed, a Joint Force Command is only charged to command one operation at a time. However, the elements of the Joint Force Command which have not deployed can provide support to other operations and missions. When a Joint Force Command is not deployed, it can assist ACO in dealing with other headquarters which are deployed in theatre for day-to-day matters and assist, for instance, with the training and preparation for future rotations.

Additionally, they support the reinforcement of cooperation with partners participating in NATO operations and help to prepare partner countries for NATO membership.

Tactical Level Commands

Air, Land and Maritime Commands

The tactical (or component) level consists of what is called Single Service Commands (SSCs): land, maritime and air commands. These service-specific commands provide expertise and support to the Joint Force Commands at the operational level in Brunssum or Naples. They report directly to SHAPE and come under the command of SACEUR.

NATO Allied Air CommandHeadquarters Allied Air Command (HQ AIRCOM)

Ramstein, Germany: this command's role is to plan and direct the air component of Alliance operations and missions, and the execution of Alliance air and missile defence operations and missions. Ramstein is also the Alliance's principal air advisor and contributes to development and transformation, engagement and outreach within its area of expertise. Ramstein, with adequate support from within and outside the NATO Command Structure can provide command and control for a small joint air operation from its static location, i.e., from Ramstein or can act as Air Component Command to support an operation which is as big or bigger than a major joint operation.

Izmir, Turkey: this command's role is to provide a deployable land command and control capability in support of a Joint Force Command running an operation larger than a major joint operation. It can also provide the core land capability for a joint operation (major or not) or a deployable command and control capability for a land operation. Izmir is also the principal land advisor for the Alliance and contributes to development and transformation, engagement and outreach within its area of expertise.

Northwood, the United Kingdom: this command's role is to provide command and control for the full spectrum of joint maritime operations and tasks. From its location in Northwood, it plans, conducts and supports joint maritime operations. It is also the Alliance's principal maritime advisor and contributes to development and transformation, engagement and outreach within its area of expertise. Northwood is ready to command a small maritime joint operation or act as the maritime component in support of an operation larger than a major joint operation.

Tactical Air C2 Elements

Two CAOCs are located at Uedem (Germany) and Torrejon (Spain). CAOCs are hybrid entities that consist of two parts: a Static Air Defence Centre (SADC) and a Deployable Air Operations Centre (D-AOC).

The Deployable Air Command and Control Centre (DACCC), located at Poggio Renatico (Italy), is a hybrid entity which consists of three elements: a Deployable Air Control Centre – Recognized Air Picture Production Centre – Sensor Fusion Post (DARS), a D-AOC and a Deployable Sensors Suite (DSS). In peacetime, the DACCC will be responsible for the initial functional training of assigned NCS JFAC personnel from both the HQ AIRCOM and the D-AOCs.


STRIKFORNATO provides a Maritime Battle Staff Operational Command, under the command of SACEUR, to deliver rapidly deployable and scalable headquarters, capable of planning and executing the full spectrum of joint maritime operations. Comprised of 13 nations, STRIKFORNATO focuses on Joint Maritime Expeditionary Operations, mainly through the integration of U.S. naval and amphibious forces into NATO operations.
