Operational intelligence

is the point where theory ceases to be a concept and transforms into action. This manual, the second volume of a trilogy dedicated to the profession, offers a clear, sober, and deeply practical guide for those working in scenarios where uncertainty is constant and responsibility is not delegated. Based on years of police experience, intelligence work, and institutional advisory, the author develops principles, techniques, and criteria that enable effective action without losing professional dignity. From operational psychology to surveillance, source management, counterintelligence, and field leadership, this work articulates a modern doctrine that integrates digital risks, perception manipulation, and identity protection in an overexposed world. An essential text for those seeking to understand the profession from within and to practice it with balance, judgment, and moral integrity.
