Offenses against the foundations of Ukraine's national security are the most dangerous encroachments on social relations that ensure state security, defense capability, independence of the country, and its constitutional system. This gives grounds for recognizing these offenses as the most dangerous and classifying them by the legislator as particularly serious or grave offences. With the help of general scientific methods (analysis, synthesis, deduction, induction, analogy, abstraction) and methods of formal logic, normative acts, materials of criminal proceedings, analytical materials, concepts, views of authors on individual issues were investigated. The normative basis of the work is the Constitution of Ukraine, the Criminal Code of Ukraine, the Law on National Security of Ukraine and the latest amendments to the Special Part of the Law of Ukraine on Criminal Responsibility. The empirical basis of the research is the judgments of domestic courts of various instances, which are placed in the Unified State Register of Court Decisions for the years 2013–2023 (189 court decisions were processed). It has been established that a typical situation is important for the development of tactics of individual investigative and investigative actions depending on the situation formed for a specific period of investigation, the development of special investigation methods and scientific recommendations for the most realistic presentation of general and special versions, their verification in relation to specific investigative situations. A typical investigative situation for the purpose of identifying persons who are of increased public danger is important for choosing the complex and sequence of investigative and operational-search actions, establishing tasks and the nature of the interaction of members of the investigative-operational group participating in the investigation.
