Dmitriy Skogorev, leader of the Russian school Systema Sibirskiy Viun, presents in these 2 volumes a complete work on defense against gun threats, disarms and the use of the snatched weapon or our own. A structured arsenal of disarming techniques based on the basic knowledge of the biomechanics of the human body, its joint mobility, psychology and the properties of firearms, and which may differ from other combat systems. If these facts are not taken into account, there will be many contradictions in the execution of our actions. Skogorev explains in detail the ways of carrying and holding the weapon, the method of quick preparation for shooting, static and moving exercises, intuitive aiming, ways of disarming against pistol threats in various situations and distances (frontal threats to the head and abdomen, to the side, from behind, sitting on a chair,...), how to get out of the line of attack, protection of the weapon, elementary acrobatics with the pistol, and ground work. A work of interest to everyone who is engaged in hand-to-hand combat and the system of protection and work with a pistol. "In a real situation, relying on the skills learned many years ago in courses is, in my opinion, somewhat presumptuous. Skills need to be improved constantly." D. Skogorev
