Switzerland participates in civilian and military peace operations conducted by international organisations and seconds experts from the Swiss Expert Pool for Civilian Peacebuilding (SEP) and Swiss military personnel to them. It also participates in EU peacekeeping operations carried out within the framework of its Common Security and Defence Policy (CSDP).

Since the operational launch of the EU's CSDP in 2003, Switzerland and the EU have been jointly engaged in a number of peacekeeping operations. In this context, Switzerland seconds experts and members of the Swiss Armed Forces to EU civilian and military missions. Switzerland is currently seconding a maximum of 26 servicemen and women to the EUFOR ALTHEA military mission in Bosnia and Herzegovina, two civilian experts to the EU Rule of Law Mission in Kosovo (EULEX), and two experts to the EU advice mission on civilian security sector reform in Mali (EUCAP Sahel Mali).
