Ordinary man in the street, who, nevertheless, familiar with the topic of firearms, will be puzzled to see such a photo. Having made the most hasty conclusions, we can say that the special forces in the photo simply do not use weapons correctly. But the specifics of the use of a firearm may vary depending on the specific combat mission, the format of the battle, and even the types of troops. An experienced fighter will apply the optimal technique of conducting a fire fight, depending on many factors. For example, when confronted with an enemy at close range, the emphasis of the machine gun on the shoulder for firing is not fundamental.
Types of firing
The most common fire-fighting tactic can be considered as fire on the "shackling" of the enemy within the framework of a certain terrain and point firing. Speaking of the first option, the accuracy here plays a secondary task. The main goal of this type of shooting is to prevent the enemy from raising their heads and leaving their positions. As a rule, this type of task is assigned to a machine gunner or a specialist with a rapid-fire weapon and a large stock of ammunition. In this case, the butt stop in the shoulder is irrelevant. It is also worth noting the minimum level of return of the latest modifications of the AK, which is often staffed with special units and riot police including.
This allows you to conduct a fire fight without resting the butt in the shoulder.
Some more reasons
Also, a riot policeman may not use the butt when he is wearing a full set of equipment, including a kevlar helmet with a visor. In this case, in order to conduct aimed fire, it is necessary to raise the machine gun a little higher, as can be seen in the pictures. In a fighter, only the lower butt of the butt rests on the shoulder and is used as a fulcrum. When the soldiers are on the march, and there is no threat of a military clash, the butt is placed on the shoulder for comfortable movement.
Eventually
Modern weapons, which are equipped with special forces, allows to obtain high accuracy and accuracy of fire, even without using the stop. On the nature of firing can affect the personal professionalism of a fighter.
