  • Abstract: Technological acceleration is compressing decision-making timelines between nuclear-armed adversaries in ways classical deterrence theory did not anticipate. This essay introduces the concept of “missile-induced systemic compression” to explain how supersonic velocity and dual-capable ambiguity—the inability to distinguish conventional from nuclear warheads—systematically reduce crisis decision windows below the threshold required for deliberative management. Examining the… Read more →

  • Abstract: Force designers face demanding methodological challenges when considering how best to adapt concepts, successfully adopt new technologies, and overhaul existing structures and processes amid a fundamentally changing geostrategic environment. The Defence Metaverse, an ultra-realistic virtual twin of the battlefield, and powerful new red AI tactics offer sovereign European solutions to tackle these challenges by… Read more →

  • Bianca Lins and Josef Schröfl, (Peter Land Group: Lausanne, 2026). pp. 236. The Cyber and Information Space Matrix offers an ambitious attempt to systematise one of the most complex terrains in contemporary security: the convergence of cyberspace, information environments, and modern conflict. Edited by Bianca Lins and Josef Schröfl, the volume positions itself at the… Read more →

  • Abstract: This paper argues that (military) leaders need to develop four critical capabilities to succeed in a disruptive and ambiguous environment. It goes on to contrast these desiderata with the fundamental trade-off between readiness and quality that permeates all military training and education, including academic studies. To counter a specific threat within a given time… Read more →

  • Abstract: This study examines how the People’s Republic of China and Taiwanese media frame United States-Taiwan arms sales using unsupervised text mining methods. It analyses English-language news coverage from 2019 to 2026, a period marked by delayed U.S. arms transfers and political debate over Taiwan’s defence spending. Drawing on articles from Taiwanese and PRC-affiliated media,… Read more →

  • Abstract: Emerging technologies increasingly accelerate intelligence and decision cycles, yet the officer as human-in-the-loop remains cognitively vulnerable within contested information environments. Artificial intelligence may both mitigate and amplify these vulnerabilities. This article conceptualises Cognitive Resilience as the systematic integration of cognitive control loops into military decision-making. It proposes a training framework—Countering Cognitive Warfare Training (CCW… Read more →

  • Abstract: Unmanned Aerial Vehicles (UAVs) and, especially, First Person View (FPV)-drones have fundamentally altered conventional and asymmetric warfare. With their rapid development since 2022 in the Russian-Ukrainian war, the Austrian Armed Forces recognised the need to develop methods to train future leaders in the intricacies of warfare with a heavy UAV presence and in integrating… Read more →

  • Vivek Chadha, (Bloomsbury Publishing India Pvt. Ltd., 2015). pp. 258 Terrorism finance remains under-examined in Indian security studies despite its central importance. Vivek Chadha’s Lifeblood of Terrorism addresses this gap through a detailed mapping of funding sources, transfer mechanisms, and operational use across India’s conflict zones. Indian Army Veteran, Colonel Chadha, leverages counterinsurgency expertise, offering enforcement-focused, state-centric… Read more →

  • Abstract: Specialised digital-reserve functions are becoming increasingly important in how states conceptualise reserves in national and allied security. Alongside traditional reserve roles, digitally-specialised reservists can mobilise scarce expertise in cyber defence, data, cloud systems, and AI. Drawing on civilian and academic professionals, they may strengthen resilience against hybrid threats while raising questions of interoperability, legality,… Read more →

  • Abstract: Digital insecurity becomes leverage only when authorities recognised by relevant governance bodies convert cyber risk into binding rules, restrictions, or supervisory duties that alter the terms of participation. This process is called institutional conversion. Three pathways matter most: reliability shock, supplier risk governance, and exposure cascade. Comparing the European Union with Nigeria shows that… Read more →
