Strategic Planning and Tactics in The Ukrainian-Russian War: What Should European Armies Implement and Avoid?

This paper’s purpose is to examine strategic and tactical lessons to be learned from the Ukrainian-Russian war and offer European armies recommendations for future preventive and defensive measures. Through analysing both warring parties’ engagement in war, this paper shows that Russian entrenching strategy is successful in containing Ukrainian forces, and using surveillance drones is an effective method of preventing surprise attacks from the adversaries’ army. Further benefits and deficiencies of Russian offense and Ukrainian defence strategies are discussed. This comparative analysis provides European armies with recommendations for implementations and avoidances.

Romania’s Defence Industrial Sector: The long road towards Modernisation and Readiness

Romania’s strategic geopolitical location between the Balkans and the Black Sea, coupled with recent international tensions, has placed it at the heart of NATO and EU defence strategies. Historically burdened by post-communist industrial decline, Romania is revitalising its defence sector through international partnerships and EU-led initiatives like the Act in Support of Ammunition Production (ASAP). However, persistent challenges within national defence company ROMARM, such as management inefficiencies, outdated technology, workforce aging, and restrictive state ownership policies, continue to impede the pace and scope of modernisation. Addressing these limitations is essential for sustaining Romania’s defence sector revitalisation. Ultimately, the effectiveness of Romania’s modernisation efforts will determine its contribution to regional stability and broader European defence resilience.

From Resilience to Deterrence: Is the EU Shifting Toward Proactive Cyber Defence?

This paper examines the European Union’s evolving cyber defence strategy in response to the growing integration of cyber operations into hybrid warfare. It traces the EU’s doctrinal shift from a reactive, resilience-based posture to one that increasingly embraces proactive deterrence, including the potential use of offensive capabilities. By analysing key strategic documents and highlighting the case of France, the study illustrates both progress and limitations. While conceptual advances are evident, practical implementation remains a national competence. The paper concludes that translating strategic ambition into credible cyber deterrence will require legal clarity, interoperability, and coordinated capability development.

The Importance of Electronic Warfare for European Land Forces: Lessons from the War in Ukraine

Armed forces in all domains are becoming increasingly reliant on electronic equipment that uses the electromagnetic spectrum (EMS) and its associated frequencies. Electronic warfare (EW) serves both to secure and to deny access to the EMS. The war in Ukraine had demonstrated that EW capabilities are now crucial for land forces, with their scope and applications continuously expanding. For example, unmanned aerial vehicles (UAVs) have become the focus of a contest in EW between Ukraine and Russia, with each side attempting to deny the other the use of these systems and the EMS necessary for their operation. European land forces should observe and assimilate the lessons from Ukraine’s experience in EW, as their own EW capabilities have become largely obsolete or insufficient.

A Legal Analysis of Space Debris I: The Kessler Syndrome and the Regulation of Space in International Law

The evolution of industrial models applied to space technologies has opened the door to space exploration and activities for smaller states and private actors. This proliferation of actors and the access to launching objects into Earth’s orbit has multiplied the amount of functional and non-functional objects in space, increasing the amount of space debris and the risk of triggering the Kessler Syndrome. This paper is the first of a series of articles analysing this challenge from a legal perspective. In this first part, the purpose is to frame the space debris threat and analyse the regulation of space in International Law.
