At the beginning of the night, the stars are dense, a bright moon hangs high in the void, sprinkling thousands of clear lights, the vast earth is covered with a layer of light veil, peaceful and quiet, on the training ground, Yang Zheng brothers and sisters recovered after resting for a long time, unwilling to be idle, asked the instructor to take it to the shooting range, one holding a rifle.

Instructor Bao took the rifle from Yang Zheng's hand and checked it, pointed to the fixed target in front and said: "The target in front is 50 meters, start with this distance, but you two must remember that in our reconnaissance battalion, when the shooting conditions are good, 200 meters is considered to be 100% accurate, and the hit rate of more than 80% is considered to be barely passing." ”

Yang Zheng raised his eyes and looked, although the target was only fifty meters, but the sky was bleak, and the lights of the training ground caused refraction, he could barely see the general outline of the target, it was not easy to hit, but he didn't complain, nodded to make a note, Instructor Bao looked at Ah Mei, and saw that Ah Mei also nodded with a calm face, so he continued: "Do you know why you are arranged to train shooting at this point?" ”

Yang Zheng vaguely guessed some reasons, but he was not sure, shook his head, and Instructor Bao continued: "Look, is the target vague at this time? In addition, the light causes refraction, and it is impossible to determine the specific location of the target, and it is very difficult to hit, but the more difficult the conditions, the better the training effect, and there is no such thing as day and night on the battlefield. ”

"Understood." The two Yang Zheng brothers and sisters exchanged glances and replied knowingly.

"It's good to understand, you can hit the target under harsh conditions, and you can hit it on the battlefield, everything starts from actual combat, there is no trick to shooting, it is practice, through a lot of training and self-understanding, it is not difficult to become a qualified shooter, but if you want to become an excellent shooter, you need talent." Instructor Bao said with satisfaction.

"Instructor, what does a good shooter look like?" Yang Zheng asked curiously.

"Excellent shooters are called snipers in our place, in the dark environment, you can hit the target 100 meters away with the help of a sniper scope, the top can hit the target 200 meters, the same is 200 meters, the difference between ordinary scouts and snipers is: one is to carry out accurate shooting under good shooting conditions, and the other is to implement accurate shooting under poor shooting conditions, the difference can be imagined." Instructor Bao said.

"What exactly are the shooting conditions?" Yang Zheng asked curiously.

"Wind, wind speed, air humidity, visibility, light, light refraction, distance, ballistics, distance, bullet weight, the curve of the earth, the visual image caused by uneven ground, and the way and force of pulling the trigger, etc., will all contribute to the accuracy of shooting, and I will slowly teach you both of these in the future." Instructor Bao explained.

Yang Zheng and the two brothers and sisters were taken aback, they didn't expect that there were so many things in the shooting, and they panicked when they thought of pulling the trigger and shooting indiscriminately in the past, no wonder they couldn't hit, it turned out that they were so exquisite, so they nodded quickly.

Instructor Bao was afraid of dampening the enthusiasm of the two, and explained, "What I just said is all sniper knowledge, our scouts here are divided into fireman, assault, sniper, blaster, infiltrator, communication hand and medical guard, etc., each person is good at different fields, pay attention to one specialty and multiple abilities, such as snipers, accurate shooting is the core, but also must master infiltration, observation, command, etc., mastering several skills are also different from person to person. ”

"That is, every scout must have a very outstanding military skill, and at the same time master other military skills?" Yang Zheng asked.

"That's right, different people are grouped together, that is, the team squad, or the reconnaissance team, everyone has their own areas of expertise, cooperate with each other, the combat effectiveness of the squad is strong, no one can master all military skills, become a generalist, the army pays attention to teamwork, does not advocate fighting alone." Instructor Bao explained.

"Understood." Yang Zheng hurriedly agreed, but his heart moved, and he said secretly: "Why can't one person master all military skills?" If a person has mastered all the military skills, can he not be a team leader? ”

Instructor Bao didn't know Yang Zheng's inner thoughts, picked up the gun and continued: "There are three postures for shooting, standing, kneeling and lying, depending on the need, hold the gun steadily, no one can take it away." ”

As he spoke, Instructor Bao put the gun on his shoulder, held it with one hand, pulled the trigger with the other, stood and aimed ahead, his face was slightly sideways to the body of the gun, and he squinted one eye and continued: "When shooting, you need to have a three-point line, that is, the eye, the crosshair, and the target, and you must calculate the parabola of the bullet flying after the bullet is discharged." ”

"What do you mean?" Yang Zheng asked suspiciously.

Instructor Bao pointed down, looked at Yang Zheng and the two brothers and sisters, and said in a deep voice: "It's very simple," when the bullet flies out of the muzzle, the bullet flies by inertia, no longer accelerates, the bullet is affected by gravity, and at the same time, there are also factors such as air and wind, and the bullet is thrown forward in a flat motion, in short, the bullet is a parabola.

"Not a straight line?" Yang Zheng was shocked and asked.

"yes, isn't it a straight line when the bullet hits out?" Ah Mei also said curiously.

"I heard that Staff Officer Lin said that you can shoot arrows, is the arrow shooting in a straight line?" Instructor Bao asked rhetorically.

"No, when you encounter the wind or something, it will float┅┅I understand, after the bullet is shot, it will be affected by all kinds of influences like an arrow, even if it is fast." Yang Zheng's eyes lit up as he spoke, and he smiled knowingly.

"That's right, shooting is restricted by too many factors, it's not easy to hit accurately, you need talent, you also need ballistic calculations, etc., I'll teach you later, now you have to remember that for bullets, from the moment they are shot, the bullet will fall and offset from all sides, and the worse the shooting conditions, the greater the deviation." Instructor Bao said seriously.

The Yang Zheng brothers and sisters secretly wrote it down, pondering as if they understood it or not.

Instructor Bao looked at the two of them and continued: "When we aim at the target horizontally, the bullet will definitely fall below the aiming point, and the farther the distance, the greater the amount of deviation, so when shooting, the barrel is slightly raised, and the bullet can only hit the target in a parabolic line, but this slight lift is very small, you don't feel it." ”

The Yang Zheng brothers and sisters didn't understand very much, and they were a little anxious, Instructor Bao took in the expressions of the two, thought about it, motioned the two to squat, picked up the military dagger and drew a straight line on the ground, and then drew a parabola, the start and end points of the parabola overlapped with the straight line, and explained: "You see, the bullets fly out in a parabola from the starting point and converge at the end point, and the end point is the point of impact, that is, the position where you want to hit." ”

The diagram is simple and straightforward, Yang Zheng and the siblings understood it at a glance, Yang Zheng asked: "Then how to calculate the height of the muzzle elevation, if it is high or low, it will definitely miss the target, right?" ”
