A Joint Expeditionary Force (JEF) Hybrid Threats Awareness Course, developed and delivered by Hybrid CoE, was held on 24–28 March 2025 with the aim of enhancing operational planning capabilities in a sub-threshold environment. The course brought together mid- to senior-ranking civilian and military officers from JEF forces and headquarters for an in-depth exploration of hybrid threats across domains.
Designed with a focus on knowledge transfer, cross-community networking, and practical application, the course examined key aspects of hybrid activity, from information operations to cyber threats and the protection of critical national infrastructure. It was developed jointly by Hybrid CoE’s Training and Exercises team in collaboration with its Communities of Interest (COIs) on Vulnerabilities and Resilience, Strategy and Defence, and Hybrid Influence, supported by the Research and Analysis function.
The curriculum provided a structured progression through conceptual foundations and practical tools. It opened with an introduction to hybrid threats and their actors, particularly Russia and China, followed by modules on disinformation, deterrence, strategic communications, cyber defence, and cognitive warfare. The Finnish Comprehensive Security Model and the CORE resilience framework featured as key case studies.
A central feature of the course was the “Hybrid Commander: SISU” wargame, a scenario-based exercise allowing participants to test their skills and insights in simulated hybrid threat conflict situations. The wargame integrated elements from earlier modules and challenged participants to apply their understanding of hybrid threat interactions in a planning context.
By combining conceptual depth with practical case studies, the JEF Hybrid Threats Awareness Course supported the identification and development of linkages between strategic and operational planning across domains relevant to modern hybrid conflict. It also served as a platform for relationship-building among officials from JEF nations, contributing to broader efforts to enhance civil-military cooperation in countering hybrid threats.
