this paper deals with military mobility, which in recent years has become one of the strategic priorities for both the North Atlantic Treaty Organization (NATO) and the European Union (EU). The authors argue that the ability to quickly transport soldiers and military equipment over long distances across member states’ territories is a prerequisite for an effective and rapid military response by the allies. An analysis of the achievements to date shows that the European Union is one of the key actors in identifying and eliminating existing barriers and initiating necessary infrastructure construction. Simultaneously, close cooperation with the North Atlantic Treaty Organization in this area allows the parties involved to achieve synergies.
