As the European Union does not maintain an official standing army of its own it relies on the framework established by each of its individual member states.
The European Union (EU) does not maintain its own colelctive standing military force but, instead, relies on the capabilities of each of its members should the worst come to pass. Europe is still militarily protected by the Cold War-era NATO alliance to an extent as twenty-two of the current EU members are also active NATO supporters / contributors. Regardless, the EU has, on call (at least theoretically), over 1.5 million personnel, nearly 7,700 tanks, 2,450 aircraft (including helicopters), and nearly 550 warships and submarines.
For 2018 there are a total of 25countries included in this listing. While there are officially twenty-eight total EU members, the Republic of Cyprus, Luxembourg, and Malta are not included in this list due to unmet conditions and minimums. The GFP list does not take into account 'BREXIT' which has put in motion the removal of the United Kingdom from the European Union. This will only be factored in once BREXIT becomes finalized on the world stage.
