The Nordic Battlegroup (NBG) is one of eighteen European Union battlegroups. It consists of around 2,500 soldiers including officers, with manpower contributed from the seven participating countries (Sweden, Finland, Norway, Ireland, Estonia, Latvia and Lithuania). The military strategic command of the force is done in cooperation with any of the suitable five Operation Headquarters framework nations at the time for deployment.Denmark has opted out of the Common Security and Defence Policy of the EU, hence all battlegroups. Norway has negotiated an opt-in to participate, even though it is not an EU member state. Sweden, Finland and Norway have planned to form a joint battlegroup.
