Henry Rimmer is an intelligence and analytical tradecraft practitioner whose work spans intelligence analysis, assessment, and operational measurement of effect. He began his career in national security in 2007, joining the British Army's Intelligence Corps. Since 2013, he has served with the British Government's intelligence analysis training team and has held a range of analyst roles across the UK intelligence assessment community. He has worked in national security environments across Europe, the Middle East, and Asia, and now delivers consultancy, training, and mentoring internationally. Through his work with financial intelligence units and national security organisations, he helps strengthen analytical capability, critical thinking, and decision-making. As a Visiting Lecturer, he brings substantial practitioner experience and a strong commitment to developing the next generation of national security practitioners.

Teaching Areas

Henry's teaching focuses on intelligence analysis, analytical tradecraft, national security decision-making, threat finance, information threats, and cyber risk. His sessions combine conceptual foundations with practical application, giving students the opportunity to develop structured analytical skills through case studies, discussion, and scenario-based exercises.

Professional Practice and Interests

Henry's professional practice centres on intelligence assessment, critical thinking, analytical capability development, and the application of tradecraft in national security and financial intelligence settings. His teaching reflects a strong interest in helping students connect policy, analysis, and operational decision-making in complex real-world environments.

Lectures

The Intelligence Cycle: A practical introduction to the intelligence cycle and its role in supporting decision-making across a range of operational contexts. Students examine how the cycle provides structure and consistency to intelligence work, and apply it through syndicate exercises that build confidence in collection planning and analytical reasoning.

The Targeting Cycle (F3EA): An introduction to the military targeting cycle – Find, Fix, Finish, Exploit, Analyse – and its relationship to the intelligence cycle. The session explores how F3EA is used in operational settings and invites students to connect the model to recent and contemporary examples.

Bulk Personal Data (BPD): An accessible introduction to Bulk Personal Data, including how it is generated, collected, and used in national security contexts. The lecture also considers the legal and ethical frameworks that govern its use, supported by relevant case studies.

Workshops and Tabletop Exercises

Threat Finance and Economic Levers (TFEL): This exercise introduces participants to threat finance across supranational, national, local, and hyper-local systems. Students apply intelligence analysis and operational environment preparation to realistic scenarios, developing recommendations for decision support, targeting, and courses of action.

Intelligence Analysis Exercise – Defend the Arctic: In this immersive tabletop exercise, participants act as intelligence analysts supporting the protection of critical national infrastructure in the Arctic High North. The exercise develops skills in structured analysis, collaborative assessment, and evidence-based recommendation-making in response to state and non-state threats.

Intelligence Analysis Exercise – Defend the Truth: This exercise places participants in the role of an intelligence analyst helping a Baltic ally respond to foreign information manipulation and interference. Students learn to identify hostile narratives, structure their analysis using NATO briefing formats, and recommend practical responses to strengthen resilience.

Intelligence Analysis Exercise – Sea Dragon: Set in the South China Sea, this immersive exercise brings together practitioners, experts, and decision-makers to assess threats, opportunities, and competing pressures in a complex strategic environment. Working in syndicates, participants use structured analytical techniques, mapping, and multi-format scenario materials to build shared understanding and produce recommendations for decision-making.

Intelligence Analysis Exercise – Hybrid Threats: Set in Europe, this challenging exercise asks participants to respond to a sophisticated threat actor employing a range of hybrid tactics, including deception and sabotage. Using original scenario materials, students develop critical thinking, analytical tradecraft, cooperation, and briefing skills in a fast-moving and demanding operational context.

Intelligence Analysis Exercise – Measurement of Effect: This exercise examines how analysts assess the impact of national security operations over time. Working in syndicates, participants follow a multi-week campaign focused on disrupting state-backed terrorist use of UAVs, developing skills in clarifying intent, establishing behavioural baselines, and assessing operational outcomes.

National Cyber Security Centre-Assured Cyber Security Risk Assessment: NCSC, a part of GCHQ, has certified this practical workshop which introduces the fundamentals of cyber security risk assessment for participants with limited prior experience. Through hands-on exercises, students learn to use core risk terminology, assess cyber threats, and build a risk register with appropriate controls.
