The European Union does not have a common army. But it can send European soldiers throughout the world. Their mission is to maintain the peace and to help populations in danger. And in the event of attack all 27 Member States agree to defend each other.
D for Defence. The European Union does not have its own army, but it can send soldiers worldwide under the EU's flag. These soldiers maintain the peace in international conflicts and help populations under threat from conflict or natural disaster. The EU increasingly coordinates foreign missions. EU soldiers operate in three continents and work with the United Nations. Mission objectives can differ: destroying arms, advising foreign armies, monitoring elections and protecting the seas from pirates. The EU is organising itself so it can deploy naval, air and troop forces. Some 1500 to 3000 EU soldiers must always be ready to act with little notice. It's what's called military rapid response. Europe has common structures to carry out operations based on the military capacities of its members. But the EU doesn't have a truly common defence force with a permanent army because the Member States are divided on this issue. Some countries are neutral like Austria and Finland. Others like the United Kingdom and some Eastern European countries prefer to cooperate with the United States to ensure their defence through NATO. But the EU countries do agree on defending each other. If one is attacked all the others must help using all the means in their power. This obligation doesn't concern neutral countries or those that have defence agreements with other military organisations.
