The EUMC was established in December 2000 by the European Council of Nice. It is one of several defence and security-related bodies established as a result of the Helsinki Headline Goal, which was decided in December 1999.

The EUMC gives military advice to the EU's High Representative (HR) and Political and Security Committee (PSC). The EUMC also oversees the European Union Military Staff (EUMS).

The relationship between the High Representative, the Military Staff and Military Committee as of November 2017:^[1] Colour key:

Role in command and control of missions edit

The EU command and control (C2) structure is directed by political bodies composed of member states' representatives, and generally requires unanimous decisions. As of April 2019:^[2]

¹ In the event of a CSDP Civilian Mission also being in the field, the relations with the Civilian Planning and Conduct Capability (CPCC) and its Civilian Operation Commander (Civ OpCdr), as well as the subordinate Head of Mission (HoM), are coordinated as shown.

² Other Component Commanders (CCs) and service branches which may be established.

³ The MPCC is part of the EUMS and Dir MPCC is double-hatted as DGEUMS. Unless the MPCC is used as Operation Headquarters (OHQ), either a national OHQ offered by member states or the NATO Command Structure (NCS) would serve this purpose. In the latter instance, Deputy Supreme Allied Commander Europe (DSACEUR), rather than Dir MPCC, would serve as Operation Commander (OpCdr).

⁴ Unless the MPCC is used as Operation Headquarters (OHQ), the MFCdr would be known as a Force Commander (FCdr), and direct a Force Headquarters (FHQ) rather than a MFHQ. Whereas the MFHQ would act both on the operational and tactical level, the FHQ would act purely on the operational level.

⁵ The political strategic level is not part of the C2 structure per se, but represents the political bodies, with associated support facilities, that determine the missions' general direction. The Council determines the role of the High Representative (HR/VP), who serves as Vice-President of the European Commission, attends European Council meetings, chairs the Foreign Affairs Council (FAC) and may chair the Political and Security Committee (PSC) in times of crisis. The HR/VP proposes and implements CSDP decisions.

⁶ Same composition as Committee of Permanent Representatives (COREPER) II, which also prepares for the CSDP-related work of the FAC.

The EUMC is chaired by a General Officer, Admiral, or Air Officer of four-star level (i.e. NATO OF-9 equivalent), who is selected by the Chiefs of Defence and appointed by the Council of the European Union. For a term of three years the chairman is the spokesperson for the EUMC. He participates in PSC meetings as appropriate, he is the military adviser to the High Representative of the Union for Foreign Affairs and Security Policy (HR) who heads the EEAS European External Action Service, he represents the primary point of contact with the Operation Commanders of the EU's military operations, and he attends Council meetings with defence and security implications.^[3]

A similar committee also exists within the North Atlantic Treaty Organisation (NATO). Those countries which are members of both EU and NATO have in most cases chosen to use the same MilRep in both organisations.
