An EU Battlegroup (EU BG) 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 (1,500 troops). Two of the battlegroups were declared to be capable of being assembled for operational deployment at any one time. The Battlegroup initiative reached full operational capacity on 1 January 2007, but, , they had yet to see operational service. They were developed from existing ad hoc missions that the European Union (EU) had undertaken. The troops and equipment are drawn from the Member States of the European Union under the direction of a "lead nation". In 2004, United Nations Secretary-General Kofi Annan welcomed the plans and emphasised the value and importance of the Battlegroups in helping the UN deal with troublespots. History Background (1999–2005) The initial idea to create EU multinational roughly battalion-sized combined arms units was first publicly raised at the European Council summit on 10–11 December 1999 in Helsinki. The Council produced the Headline Goal 2003 and specified the need for a rapid response capability that members should provide in small forces at high readiness. The idea was reiterated at a Franco-British summit on 4 February 2003 in Le Touquet which highlighted as a priority the need to improve rapid response capabilities, "including initial deployment of land, sea and air forces within 5–10 days." This was again described as essential in the "Headline Goal 2010". Operation Artemis in 2003 showed an EU rapid reaction and deployment of forces in a short time scale – with the EU going from Crisis Management Concept to operation launch in just three weeks, then taking a further 20 days for substantial deployment. Its success provided a template for the future rapid response deployments allowing the idea to be considered more practically. The following Franco-British summit in November of that year stated that, building on the experience of the operation, the EU should be able and willing to deploy forces within 15 days in response to a UN request. It called specifically for "Battlegroup sized forces of around 1500 land forces, personnel, offered by a single nation or through a multinational or framework nation force package". On 10 February 2004, France, Germany and the United Kingdom released a paper outlining the "Battlegroup concept".
