Abstract: The subject of the study is the classification of special equipment of the internal affairs bodies, the grounds for its classification, the requirements for the names of groups of equipment. The object of the study is the normative legal acts of the Ministry of Internal Affairs of Russia, containing information about the concept of "special equipment of internal affairs bodies", about its division into groups reflecting the system of scientific and technical information adopted by the Ministry of Internal Affairs, as well as scientific works devoted to classification as a method of scientific research, educational literature in this subject area. Using scientific methods of cognition, such as induction, deduction, analysis, synthesis, classification, the authors discuss the concepts of "special", "technique", "special technique of internal affairs bodies", contradictions in regulatory legal acts reflecting the classification of the above-mentioned technique.
The novelty of the study lies in clarifying the concept of "special equipment of internal affairs bodies", identifying criteria for attributing technical means to this group. The choice of a universal basis for classification, such as the purpose of technology, is justified. The division of special equipment of internal affairs bodies into groups has been carried out and their names corresponding to the terminology of state standards and departmental regulatory legal acts have been proposed.
The main result of the work is the development of a draft structure of the List of samples (complexes, systems) of special equipment accepted for the supply of internal affairs bodies of the Russian Federation. It is proposed to supplement its content with the sections "Special equipment", "Conventional equipment", "Equipment" and adjust the name.

Abstract: The subject of the study is the classification of inspection and search equipment. The object of research in the work is the tactical and technical characteristics of various samples of inspection and search equipment, the features of its design, the principles of operation of the devices. The paper discusses such classifiers as the type of the detected object, the design features of the product, the specifics of the impact on the surrounding space, the physical principle of operation. The author pays special attention to the search, formulation and discussion of classification features that allow us to fully characterize not only the purpose and design of a specific inspection or search technical means, but also the principle of operation, in order to form a single conceptual apparatus in the subject area.    The main results of the study are a comprehensive consideration of the classification of inspection and search equipment, the formulation of the names of groups of inspection and search equipment, based on its principle of operation. Within the framework of individual groups, an additional division of equipment into subgroups is proposed, which allows even more accurately characterizing its capabilities.
The novelty of the research also lies in the discussion of the advantages and disadvantages of classifying signs of inspection and search equipment, in the proposal of a classification scheme based on the physical principles of the devices. For a more complete understanding of the developed classification, the author provides examples of search and inspection devices of different types according to the developed criteria.

Abstract: The article contains the author’s technique of formation of radio communication skills during the process of local police officers training within the practical lessons in the discipline “Special technique of internal affairs bodies”. This technique helps to form necessary competences in the sphere of service radio communication with minimum participation of a teacher in the process of radio communication. The research contains samples of educational materials (procedure charts, radio communication control charts for the operator of the main communication station, a radio communication control chart for the teacher), necessary for a lesson. The author considers the knowledge assessment criteria for the section “Means of communication of internal affairs bodies”, related to radio communication.
The topicality of the research is determined by the necessity to form stable skills of using service radio communication and radio exchange during the local police officers service. The author emphasizes that pedagogical literature doesn’t cover this issue. 
The scientific novelty of the research consists in the development of the author’s technique of formation of practical skills of radio communication within the educational process preparing the future local police officers. The technique contains the action plan for a teacher, the samples of educational materials, and knowledge assessment criteria, and helps to effectively form radio communication competences of students. The main approaches of this research can be used for other specializations.
