The article states that nowadays situations in Ukraine shows that the theory of military activity of law enforcement forces needs a new development in the terms of settlement of armed confrontation in separate areas of Donetsk and Luhansk areas. Therefore, the issues of regulatory and legal support of law enforcement agencies in responding to crisis situations come to the fore. The analysis of normative legal acts shows that legal norms are not formulated clearly enough and ambiguously interpreted by law enforcement agencies. Therefore, it is necessary to refine the legislative mechanism for preventing and responding to crisis situations that threaten the national security of Ukraine. Therefore, the purpose of the research is to comprehensively reveal the essence and features of the legal regulations of combat operations of the security and defense sector of Ukraine in crisis situations and to develop specific practical recommendations, scientifically sound proposals for improving State governance in this field. In order to research the best practices of Ukraine on the functioning of Public mechanisms of response of the security and defense sector of Ukraine to crisis situations during the Anti-Terrorist Operation and the Joint Forces Operation in some districts of Donetsk and Luhansk regions, an expert survey of anti-terrorist security experts was conducted. The results of the survey provided an opportunity to identify the main problematic issues in the functioning of the anti-terrorist security system and provide appropriate development proposals. The State authorities today need to focus on improving the organization of management, establishing interagency cooperation between government agencies, increasing the level of pre-training of personnel, a clear definition of tasks for law enforcement units during special operations. Areas of further research will be aimed at developing State mechanisms of responding by the components of the security and defense sector of Ukraine to crisis situations
