1993–2000: Background

The Common Foreign and Security Policy (CFSP) was introduced as a pillar of the EU by the Treaty of Maastricht in 1993, based on the earlier 1970 European Political Cooperation (EPC). The CFSP was to include ‘all questions related to the security of the Union, including the eventual framing of a common defence policy, which might in time lead to a common defence’.

In December 1998 the Franco-British Saint-Malo declaration stated that the EU ‘must have the capacity for autonomous action, backed up by credible military forces, the means to decide to use them, and a readiness to do so, in order to respond to international crises’. This marked a British change of course, as it previously had blocked any development of EU autonomous military capabilities.

At the European Council in Cologne in June 1999 the European Security and Defence Identity (ESDI) - formed in 1996 as a project between Western European Union's (WEU) and the North Atlantic Treaty Organisation (NATO) - was transferred to the EU and renamed the European Security and Defence Policy (ESDP). The main goal of this newly established CSDP was to deal with crisis management outside EU territory.

2001: Creation as a Council body

In 2000 and 2001 a number of Council bodies were established as part of the ESDP:

• Political and Security Committee (PSC), a preparatory body of ambassadorial level representatives thar observes the international situation, helps to define CFSP and ESDP policies and prepares a coherent EU response to a crisis
• EU Military Committee (EUMC), the Council's highest military body, composed of member states' Chiefs of Defence, who are regularly represented by their permanent military representatives. The EUMC provides the PSC with advice and recommendations on all military matters within the EU.
• European Union Military Staff (EUMS), a part of the General Secretariat whose primary task was to by EUMC's working and advisory body

In 2003 the Treaty of Nice provided the ESDP's legal foundation, in terms of competences, organisation, structures and assets.

2009: Transfer to the External Action Service

Upon the entry into force of the Treaty of Lisbon in 2009 the EUMS was transferred from the Council's General Secretariat to become a Directorate-General (DG) of the newly established European External Action Service (EEAS) - the EU's diplomatic service, a hybrid Council-Commission body resulting from a merger of the external relations departments of the Council and relevant international relations departments of the European Commission.

2016: Addition of the MPCC

In 2016 European Union Global Strategy was presented by HR Federica Mogherini and welcomed by the European Council. The implementation of this strategy in the field of CSDP has included the establishment of the Military Planning and Conduct Capability (MPCC), which gives the EUMS the role of commanding operations directly.

Director General

The EUMS is led by the Director General (DGEUMS, a three-star general).^[3]

Since 2017 DGEUMS has also served as Director of the Military Planning and Conduct Capability, and as such assumes the function of the single commander for all non-executive military missions, exercising command and control over the current three training Missions and other possible future non-executive military Missions.

DGEUMS is assisted by the Deputy Director General and the Chef of Staff (DDG/COS, a two-star general).^[3]

Military Planning and Conduct Capability

The Military Planning and Conduct Capability (MPCC) is an EUMS facility that provides a permanent operational headquarters at the military strategic level for military operations. The MPCC reports to the Political and Security Committee (PSC) and informing the European Union Military Committee (EUMC).^[4]

Presently the MPCC may only run non-executive operations. By the end of 2020 the MPCC will also be capable of running executive operations of up to 2500 troops, i.e. the size of one battle group.^[5]

The MPCC cooperates with its existing civilian counterpart, the Civilian Planning and Conduct Capability (CPCC), through a Joint Support Coordination Cell (JSCC).

Directorates

The EUMS has five directorates, each led by a one-star commander.^[3]

Other units

Other units at the EUMS include:^[6]

• ACOS Synchronisation unit, which assists the Chief of Staff in the coordination and synchronization of the EUMS internal processes and information flows, to facilitate and canalise the support the EUMS provides to the Chairman of the EUMC, and to support him in the preparation and management of meetings.
• ACOS external relations unit, which develops policy for, and maintain the military dimension of, all EUMS' external relations in close cooperation with EEAS Management Directorates and the CMPD. This involves coordinating military-to-military cooperation with International Organisations, Strategic Partners; and Third States. The office is also responsible for all Public Information/Press Relations issues in close collaboration with the EEAS Strategic Communications Division.
• EU cell at SHAPE (EUCS), a unit that prepares for EU operations having recourse to NATO common assets and capabilities under Berlin plus arrangements and to support DSACEUR in his role as a potential operational commander for an EU-led operation. It contributes to full transparency between NATO and the EU embodying their strategic partnership in crisis management.
