The transition from SFOR to EUFOR was largely a change of name and commanders: 80% of the troops remained in place.

For this mission, the European Union Military Staff is using NATO's Supreme Headquarters Allied Powers Europe (SHAPE) as the EU's Operational Headquarters (OHQ) and is working through the Deputy to the Supreme Allied Commander Europe, a European officer.

EUFOR assumed all the missions of SFOR, except for the hunt for individuals indicted by the war crimes tribunal, notably Radovan Karadžić, former leader of Republika Srpska, and Ratko Mladić, their former military leader, which remained a mission for NATO[2] through NATO Headquarters Sarajevo.

[4] EUFOR does have police duties against organised crime, which is believed to be linked to suspected war criminals.

As of February 2023[update], the total force of EUFOR is approximately 1,000 troops from 22 countries, including EU member states and non-EU "Troop Contributing Countries" (TCC) are present within EUFOR (Albania, Austria, Belgium, Bulgaria, Chile, Czech Republic, France, Germany, Greece, Hungary, Ireland, Italy, the Netherlands, Poland, Portugal, North Macedonia, Romania, Slovakia, Slovenia, Spain, Switzerland, and Turkey).
