Military mobility, defined as the capacity of armed forces to swiftly move troops and equipment across the European Union (EU), is a crucial but long-overlooked aspect of European defence. After decades of underinvestment and unresolved obstacles, there is a need to intensify coordinated and integrated efforts at EU, North Atlantic Treaty Organization (NATO) and Member State level to increase resources and address physical, legislative, and regulatory barriers that continue to cause delays and disruptions for military forces. Failure to act would leave armed forces unprepared in the face of threats, and undermine the security of citizens. Ultimately, this could jeopardise the EU's ability to demonstrate credible deterrence and achieve defence readiness. Upcoming initiatives at EU level represent an opportunity to finally adopt a comprehensive approach to military mobility. Clear added value could be provided by not only increasing targeted investment in dual-use infrastructure and reducing regulatory burdens, but also addressing issues in related security and defence domains that clearly impact military mobility decisions, including investment in cybersecurity, logistics hubs, stockpiling and transport innovation to enhance the security and resilience of military networks. For current ambitious defence initiatives, allocating sufficient budgetary resources is essential. This briefing looks within and beyond the current framework and explores the potential impact of additional investment of between €75 billion and €100 billion until 2035 to improve the current state of infrastructure. Our analysis finds that the added value associated with a larger amount of funds invested collectively leads to benefits which are almost three times higher (€21 billion additional GDP per year in 2035) than when Member States invest separately and in an uncoordinated way.
