After several days of careful preparation, after consulting the platoon commander Gao, Yang Wenbin finally changed the "Four Meetings" lesson plan, and used the weekend to organize the soldiers of the squad to train repeatedly.

At noon today, Yang Wenbin received a notice from the company's correspondent saying that there was no need to engage in the "four skills" subject. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 Info heard that he didn't have to do it himself, Yang Wenbin's nervous nerves slackened, thinking that this matter was over.

In the afternoon, he received a call from Deputy Political Commissar Zhan, informing him to continue to counsel Pengfei.

Yang Wenbin had just entered the office and sat down, but before he could sit down, a company soldier came to him and said that the headquarters had notified him to go to the training ground immediately.

He hurriedly ran to the regimental playground and learned that the headquarters had randomly checked the preparations for the preparatory period of the training and notified him to conduct the "four meetings" teaching assessment.

Yang Wenbin quickly rushed back to the company and gathered the team of his class. After preparing weapons and equipment, and taking the team to the north playground, they hurriedly put on their clothes.

He drew the subject of accurate shooting with the XX-1 automatic rifle.

After reporting to the venue assessor, Yang Wenbin began the first "Four Sessions" subject teaching in his life:

"Subject: XX-1 automatic rifle precision shooting

Objective: Learn how to shoot with a support, and master the skills of accurate shooting with a support.

Contents: 1. Utilization of backings; 2. According to the gun; 3. Aiming; Fourth, firing.

Method: Explain and demonstrate, practice in different classes

Location: Shooting range

Time: half an hour

Requirements: ..."

After Yang Wenbin issued the subject in an orderly manner, he began to explain:

"Let's start the lesson!

First, the use of backings

When using a backing, you can place the underside of the crosshairs on the backing to reduce projectile dispersion.

When using the support under the reticle, the center of gravity is shifted back due to the change of the position of the fulcrum of the gun, and the projectile hits about 25-30 cm higher than the base under the gauge ruler at a distance of about 25-30 meters.

Therefore, when using the undertone of the reticle, the aiming point should be lowered by about 25-30cm. When using the lower shield with the backing, the aiming point remains the same.

Lying position, relying on the gun, aiming, firing:

(1) According to the gun.

According to the essence of the gun, the front end of the lower cover of the gun is placed on the backing, and the right side of the body is slightly in a line with the gun body.

The right hand grips the grip forward, the first section of the index finger rests on the trigger, the right upper arm is slightly vertical, the right elbow is on the ground, the left hand holds the cover or small grip, the left elbow is on the ground, the elbows remain stable, the chest is erect, the body is slightly forward, the upper body naturally collapses, and the force of both hands remains unchanged, so that the butt is indeed lower than the shoulder socket and naturally close to the cheek.

(2) Aiming.

The essentials of aiming are: First, make the reticle line naturally pointing towards the target. If you do not aim at the target, you must not give in and twist the gun, and you must adjust your posture.

When you need to correct your direction, you can move your body or your elbows left and right.

When you need to correct the height, you can move the whole body back and forth or the two elbows outside the support, and it is best to adjust the support when conditions permit.

XX-！ When shooting at a chest ring target at 100 meters, the automatic rifle can be aimed at the bull's-eye with a ruler "1".

The method is to see the hole and the front sight with the right eye, so that the front sight is located in the middle of the hole and points to the point of sight.

At this time, the correct aiming situation is clearly seen in the center of the crosshair and the sight hole, while the target is more blurred.

(3) Shooting. Firing is the last step in completing the shot. An even and straight shot is the key to getting an accurate shot.

The essentials of firing are: pull the trigger back evenly and upright with the first segment of the index finger of the right hand, and the strength of the remaining finger remains unchanged.

When the reticle is close to the aiming point, begin to pre-press the trigger, and slow down the breathing.

When the aiming line is directed at the aiming point, the breathing should be stopped and the pressure on the trigger should continue to increase until the shot is fired.

If the aiming line deviates from the aiming point or cannot continue to stop breathing, the pressure on the trigger should be neither released nor increased, and the trigger should be continued to be pulled after the aiming is corrected or the air is breathed to complete the firing.

The above is the essentials of shooting in a lying position with a support, do you know it well, comrades? Yang Wenbin finished talking about the essentials and asked loudly.

"Clear!" The warriors replied loudly.

After explaining the essentials, Yang Wenbin organized the fighters to conduct personal experience exercises, asking the fighters to pay attention to the essentials of the movements, and then he corrected the wrong movements one by one.

"In the process of shooting, we are prone to the following mistakes:

One is that the shoulder position is incorrect. Incorrect shoulder fare when firing will result in shooting deviation. Usually the shoulder is too low and easy to low; If the shoulder is too high, it is easy to hit high.

Correction method: Check whether the shoulder position is correct by touching and pushing by others.

The second is that the two hands are not used to exert force appropriately, and the two hands are used to control the shaking of the gun with force, resulting in muscle tension, improper direction of force, and unstable posture, so that the gun swings at an angle and increases the spread of projectiles.

Correction method: It should be emphasized that the gun should be used upright and backward with appropriate force, and the direction of force should be consistent with the direction of the recoil.

The third is that the timing of the firing is not well controlled.

Correction method: It is normal to point out that the pointing of the aiming line is slightly shaking near the aiming point, and when the aiming line is slightly shaking near the aiming point, it should be fired at the right time.

Fourth, stop breathing too early. How to correct it: Repeatedly experience the essentials of stopping breathing naturally when the aiming line is pointing at the aiming point or shaking slightly near the aiming point.

After strenuous exercise, take a deep breath before stopping breathing.

Five is shrugging, winking, and slamming the trigger. Correction method: According to the essentials of the action, focus the main energy and vision on the correct relationship between the front sight and the mouth, and achieve natural firing.

Sixth, the gun surface is tilted. Corrective Method: Keep the gun face upright. ”

Just as the subject was proceeding step by step, the examiner present stopped the subject and called Yang Wenbin over.

"The subject demonstration is good, as a local college student cadre, the 'Four Sessions' subject can be done to this extent, and it also shows that you have put in a lot of effort."

The examiner paused and said, "The shooting subject is well demonstrated, but I wonder how well you have mastered the theory of shooting?" Let me ask you a question, right? What is projectile dispersion and what are the reasons? ”

This question is not difficult for Yang Wenbin, who only finished studying at the Army Academy a few months ago, and reviewed it two days ago, and immediately replied:

"By the shooter with the same weapon, firing multiple rounds in the same conditions as possible, each warhead cannot fly along the same day's route and will not fall on the same point.

This phenomenon of separation between projectiles is called projectile dispersion.

Projectile dispersion is caused by a number of tiny, accidental causes. The main ones are:

One is the reason for the operation of the shooter. When a shooter fires multiple bullets, due to the consumption of physical strength and energy, it is impossible to maintain a completely consistent shooting posture, gun rejection, aiming, firing and other actions.

When firing in bursts of automatic weapons, it is more difficult to operate the gun due to the recoil of the weapon and the jumping of the barrel, which will cause the inconsistency of the firing angle and direction of each projectile, resulting in the dispersion of the projectile.

In addition, changes in the shooter's psychological factors will also increase the projectile spread.

The second is the reason for weapons and ammunition. When firing, the temperature of the barrel is different, and the muzzle velocity of the projectile is also different, and the temperature increases within a certain range, and the muzzle velocity increases; Beyond a certain range, the temperature increases, and the muzzle velocity decreases. Therefore, when many bullets are fired, the high and low (distance) dispersion of the projectile increases.

After firing 10-15 rounds in a row, the temperature of the barrel increases, and the muzzle velocity increases by about 2 m/s; After 20-25 rounds, the muzzle velocity increases by 5 m/s. When submachine guns and squad light machine guns fire 90-120 rounds in a row, the muzzle velocity of the warhead increases by 10 m/s, and when the fire continues, the temperature in the chamber is too high and the barrel expands, and the muzzle velocity begins to decrease.

Rust or rust marks in the chamber also increase projectile spread. When firing at a weapon that has not been wiped for several days after firing, the position of the average impact point will increase, and the projectile dispersion will increase by about 20-30%

Due to a certain permissible error in the manufacture of ammunition, there are certain differences in the weight, mass, charge density, temperature (moisture) poison, shape, weight, and diameter of each bullet in the same batch of ammunition, and these differences will lead to the inconsistency of the initial velocity of the projectile and the dispersion of the projectile.

For example: the Type 53 light bullet, the warhead weighs 9.6 grams, the allowable error is ±0.1 grams, and the muzzle velocity when fired with the Type 67-1 heavy machine gun is 840 m/s.

This is the average, some projectiles may be at 845 m/s, some may also be 835 m/s. The muzzle velocity is large, the projectile hits high and far, the muzzle velocity is low, and the projectile hits low and close.

The third is the reason for external conditions. When shooting, the air temperature, air pressure, wind speed, and wind direction are also constantly changing, especially the wind speed and wind direction, even in sunny and windless conditions, it is impossible to be completely consistent, there will always be slight differences.

Therefore, the impact of each launched warhead when flying in the air is different, resulting in inconsistent height and direction of the impact point.

Due to the above reasons, the projectiles have their own ballistics and impact points, forming a natural dispersion of the projectiles.

Of the three reasons for the projectile to walk, the main one is the one for the shooter's operation.

The shooter has good shooting skills, stable psychological quality, and small projectile dispersion; The dispersion of the reflective bomb is large. For example, at the World Special Police Competition held in Austria in 1989, Chinese players used ordinary XX-1 7.62 mm automatic rifles to compete with Western countries using weapons equipped with scopes, and achieved excellent results. ”

Seeing that he was not asked, the examiner let Yang Wenbin go, passed his subjects, and moved on to the subjects of the next company.

After packing up the equipment and lesson plans, he went upstairs to report to the company commander, and after telling the story, he couldn't help laughing.

It seems that there is nothing too difficult about military subjects, as long as you study hard and prepare carefully, you will definitely succeed.

The success of the first assessment further stimulated Yang Wenbin's fighting spirit: "I want to challenge fate!" There is nothing impossible in the world, as long as you work hard, you will succeed! ”
