Abstract: The research subject is legal and organizational problems of preparation of police officers to the situations involving use of firearms as one of the forms of administrative coercion. Solutions to such problems lie within the improvement and conjunction of particular aspects of professional training (weapons training, legal training, tactical training, physical training, psychological training, etc.). A conceptually new way to solve these problems is the cybernetic approach based on three fundamental aspects of cybernetics: information, management and organizational. The research methodology is based on such general philosophical methods as observation and modeling, and the method of comparative analysis and the system method. The author considers a cybernetic system, in which the mechanism of decision-making over the issue of use of firearms by a police officer (management object) is a component of the system of official activities and professional training of a police officer (management cycle). The author concludes that all the elements of the system of police officers training for use of firearms should be aimed at the final result – effective and legal use of firearms. To achieve this result, the author offers particular procedures corresponding with fundamental aspects of cybernetics: observation of certain information background during training (situational targets, environment, light, sounds, etc.); appropriate reflection of all elements of the training system in official documents, optimal target setting in the training process.
