Creating a fully-fledged European Defence Union by 2025 is imperative to Europe's security and to build a Union
that protects. A smooth, efficient and effective movement of military personnel and assets across and beyond the
EU will enhance the EU's preparedness and response to crises. It will enable EU Member States to act faster, in line with their defence needs and responsibilities, both in the context of the Common Security and Defence Policy missions and operations, and in the framework of national and multinational activities. Currently, cross-border mobility is still hampered by a number of barriers that can lead to delays, disruption, higher costs or increased vulnerability."
