An EU Battlegroup is a military unit adhering to the Common Security and Defence Policy (CSDP) of the European Union (EU). Often based on contributions from a coalition of member states, each of the eighteen Battlegroups consists of a battalion-sized force reinforced with combat support elements. Two of the battlegroups were to be capable for operational deployment at any one time. The civil power that oversees these battlegroups is the Council of the European Union.

The Permanent Structured Cooperation (PESCO) is the part of the European Union's (EU) security and defence policy (CSDP) in which 26 of the 27 national armed forces pursue structural integration. Based on Article 42.6 and Protocol 10 of the Treaty on European Union, introduced by the Treaty of Lisbon in 2009, PESCO was first initiated in 2017. The initial integration within the PESCO format is a number of projects which launched in 2018.
In 2009 the Treaty of Lisbon (signing depicted) entered into force, enabling permanent structured cooperation in defence between a subset of willing member states.
On 13 November 2017, Foreign and Defence Ministers from 23 EU states signed the Joint notification on setting up PESCO in a Foreign Affairs Council chaired by the High Representative for Foreign Affairs, Federica Mogherini.
