The European Union Military Staff (EUMS) is a part of the European Union's Common Security and Defence Policy. It provides military expertise and support to the EU's decision-making bodies, helping to plan and conduct military operations and missions. The EUMS works closely with other EU institutions and member states to ensure effective coordination in defense matters. The EUMS is composed of military personnel from EU member states and is based in Brussels, Belgium. Its primary role includes analyzing military situations, advising on military strategy, and facilitating cooperation among the armed forces of EU countries. This enhances the EU's ability to respond to crises and maintain peace and security.
