Finabel is an organisation promoting cooperation and interoperability between the national armies of the member states of the European Union (EU). Founded in 1953, Finabel is controlled by the member states' army chiefs of staff, and the organisation's work agenda consists of studies and working groups. Finabel has a relatively small permanent secretariat. The studies carried out by Finabel take the form of reports resulting from studies entrusted to the working groups, agreements relating to the military characteristics of equipment, as well as conventions that standardise procedures, testing methods and glossaries in order to facilitate exchanges between member states.
The Finabel coordination committee is a land forces organisation comprising 21 Member states of the European Union with a view to promote interoperability between the land forces of its Member states. Membership is open to all of the Member states of the European Union
