During this course, students learn the rules of shooting a pistol using a barricade/cover. After warming up and reviewing the basics of combat shooting, we begin preliminary shooting. Then we continue with learning how to look around the corner of a wall or door frame. This seemingly simple activity requires an understanding of the rules of indoor combat. And this, as often turns out, is not so obvious. Another important part of the training is skillfully using holes in the barricade to improve our skills. The training ends with a short shooting course in which the entire training program is summarized. Just having cover is not enough, we also need to know how to use this advantage in battle!
