Troop contributions

When a NATO operation or mission is deemed necessary, NATO member and partner countries volunteer personnel, equipment and resources for the mission. These national contributions operate under the aegis of the Alliance.

  • An alliance of 30 sovereign countries, NATO relies on the military forces of its member countries to carry out an operation or mission because it does not possess military forces of its own.  
  • Personnel serving in a NATO operation are referred to as “NATO forces”, but are actually multinational forces from NATO countries and, in some cases, partner or other troop-contributing countries.
  •  “Force generation” is the procedure by which Allies (and partner countries) resource the personnel and equipment needed to carry out North Atlantic Council-approved operations and missions.
  • National capitals take the final decision on whether to contribute to a NATO-led operation or mission.
  • Allied Command Operations (ACO), commanded by the Supreme Allied Commander Europe (SACEUR), is responsible for executing all NATO operations and missions, and the Deputy SACEUR coordinates troop contributions.



  • Obtaining troop contributions

    When the North Atlantic Council consents to an operation or mission, NATO’s military authorities draft a concept of operations – referred to as CONOPS – which outlines the minimum military requirements that are needed.  Force generation is the procedure in which those required resources are obtained from Allies (and partners) to provide the Operational Commander with the necessary capabilities at the right scale and readiness to accomplish the mission. Force generation applies to all current NATO-led operations and missions.

    The force generation process

    The force generation process follows a standard procedure and is handled by the Allied Command Operations (ACO) Force Generation Branch and National Military Representatives (NMRs). For a given operation or mission, the Operational Commander sends his requirements in terms of equipment, manpower and resources (referred to as the Combined Joint Statement of Requirements) to ACO.  It is then passed to NATO member countries and, in some cases, partner countries.  While the Force Generation Branch at ACO is responsible for resourcing the required capabilities, the final decision on contributions is taken by national capitals. 

    At the subsequent Force Generation Conference, NATO and partner countries then make formal offers of personnel and equipment to support the operation or mission. Since 2003, a Global Force Generation Conference has been held as required to discuss all NATO-led operations and missions.

    These contributions may be subject to some national limitations (known as “caveats”) such as rules of engagement. These restrictions influence NATO’s operational planning. Therefore, the Alliance seeks national contributions with as few caveats as possible.

    The force generation process is complete when nations reply with a Force Preparation (FORCEPREP) message, which provides the details of the national contributions as well as any caveats on the employment of forces.

    Countries that provide leadership for an entire operation or mission, or take responsibility for central elements such as the land brigade in the Very High Readiness Joint Task Force (VJTF), are identified as “framework nations". They typically provide the command element and a significant part of the forces, and will coordinate with other Allies to fill the remainder of the force required.

    Although NATO as an alliance does own and maintain some specialised equipment, such as the AWACS aircraft and strategic communications equipment, troop-contributing countries generally commit the equipment necessary to support their personnel in pursuit of operational objectives.

    Coordinating troop contributions for non-NATO operations

    Over the years, the Alliance has developed significant expertise in coordinating troop contributions for multinational operations and has offered this expertise in support of non-NATO operations.  

    Under the Berlin Plus agreement, the Alliance cooperates closely with the European Union (EU) in the resourcing of selected operations. When requested by the EU, NATO’s Deputy SACEUR and his staff provide support in coordinating member countries’ troop contributions. For example, the Deputy SACEUR was identified as operational commander for Operation Althea, the EU-led operation in Bosnia and Herzegovina, and was responsible for force generation.

    NATO also provided force generation support to Germany and the Netherlands, during their leadership of the UN-mandated International Security Assistance Force (ISAF) in 2003 in Afghanistan, prior to its conversion into a NATO-led operation.

  • Force generation through time

    For much of NATO’s history, the Alliance’s primary operational commitment was focused on the former border between East and West Germany. For over 40 years, NATO strategists spoke of medium- and long-term “force plans” because during that time, the Alliance maintained static, “conventional” forces in former West Germany, poised for an attack from the former Soviet Union. Beginning in 1986, conventional forces were reduced and bases of individual NATO countries in Germany were largely dismantled or converted to other use after the Cold War.

    NATO’s first major land expeditionary operation took place in Bosnia and Herzegovina as a result of the 1995 Dayton Peace Accords. The NATO force generation process, which is still in use today, was developed during the NATO-led operations in Bosnia and Herzegovina, and later in Kosovo.

    Transforming to meet operational needs

    While the core procedures for contributing troops and equipment remain the same, the force generation process has been refined to reflect changes in the types of operations and missions that NATO conducts.

    For example, the Provincial Reconstruction Teams (PRTs) established in Afghanistan under the NATO-led ISAF operation, were comprised of a unique combination of military and civilian personnel who worked to extend the authority of the central Afghan government in remote areas, and to facilitate development and reconstruction. NATO was involved in generating forces for the military component of a PRT, while it was the responsibility of the contributing country to staff the civilian components. As a result, PRTs were a hybrid of personnel who fell under either NATO or national chains of command. Although PRTs were gradually phased out by end 2014 in agreement with the Afghan authorities, they illustrate the need for great flexibility in force generation processes in order to achieve operational objectives.

    Today, NATO military planners are looking beyond immediate needs, allowing both the Alliance and troop-contributing countries to plan their resources better. The goal is to understand the relationships at play in order to achieve fair and realistic burden-sharing during NATO-led operations and missions.
