Wikipedia describes the European Army as follows:

The European army or EU army are terms for a hypothetical army of the European Union which would supersede the Common Security and Defence Policy and would go beyond the proposed European Defence Union. Currently, there is no such army, and defence is a matter for the member states.

The idea of such an army is brought up periodically, although so far there are no plans in the works to create it.

Will there be a European Army before 2032?

This question will resolve as Yes if, before January 1, 2032, there is legislation passed in at least 5 European countries (including one of France, Germany, UK) which makes provisions for an army consisting of units from multiple countries.

Lower level army units (eg platoons, companies, battalions, regiments) need not be mixed. (For example, often countries have armies formed from regional regiments and are still considered national armies). However, senior levels need to be staffed by officers from a range of countries.

The army needs to be planned to be an "Army". ie a joint battalion (eg the one formed between the Dutch and Germans) would not count. For this question, this means that at least 30,000 soldiers need to be planned to be in such an army.

The army needs to report to a supranational organization. It need not be the an EU body or any existing organization. It does need to be specifically European. eg A G7 army would not count.
