Su Qin explained earnestly.

It mainly talks about how to deal with complex winds, how to measure wind direction and speed, and how to measure distances.

He started by talking about how to use the instrument.

Then he talked about what to do if there is no measuring instrument, such as how to estimate the wind direction and speed from cooking smoke, or how to determine the wind direction and speed from swaying trees and weeds.

Finally, he taught Li Yu to measure distances using the earthen method.

The first is the eye-jumping method.

The principle of the eye-skipping method is that the interval between the pupils of the two eyes is about one-tenth of the length of one's own arm, and the distance from the standing point to the target is obtained by multiplying the width of the measured object by 10.

Inexperienced people can make a lot of mistakes when using the eye-jumping method, but it has proven to be very powerful with a lot of practice.

During the period of resisting the United States, aiding Korea, Zhang Taofang, an excellent sniper of our army, was best at this method.

Of course, he was forced.

He doesn't have a good sniper rifle!

In the sniper battle in Shangganling, Zhang Taofang used the Mosin Nagant rifle to snipe the enemy, this rifle has no scope, so he mainly relies on visual measurement, Zhang Taofang used the jumping eye method to measure the range, sniping 214 enemies in 3 months, which is enough to prove the accuracy of the proficient use of the jumping eye method for ranging.

After talking about the eye-jumping method, Su Qin told Li Yu about a simple method used by FBI agents - thumb distance measurement.

Thumb distance measurement is different from the eye-skipping method, which can only target people on foot.

The rangefinder extends his right arm and gives a thumbs up to the target.

If the target step is exactly across the entire width of the nail, the distance is about 50 yards, 2 steps 100 yards, 3 steps 150 yards, and 4 steps 200 yards.

After that, Su Qin taught Li Yu another method - the football field ranging method.

When it comes to long-range ranging, the United States and other Western special forces prefer this "football field ranging method".

After talking about this, Su Qin earnestly advised: "However, Li Yu, you must firmly remember one point, whether it is the eye-jumping method, the thumb method, or the football field method, it is very subjective, errors must be inevitable, and what applies to me may not apply to you, so the only way is to practice more, practice over and over again, find the method that you like and suit yourself, and practice until it becomes instinct."

In addition, as snipers, we must be careful enough in life and learn to observe common objects in life often, because they can provide an accurate reference for our ranging.

Telephone poles, for example, are a prime example.

In the field, most utilities bury as few poles as possible and the spacing between poles is fixed in order to save money. We can estimate the distance from the poles.

However, when looking down from a high place, when observing along a straight road or railway, when the target is on a flat surface such as a snowy desert, when looking up, when the target is near a tall object such as a canyon or a high wall, or when the target is in a small field of view such as crossing an alley, there are often errors in our estimates compared with the actual situation, and how to eliminate this error also requires continuous practice. ”

Su Qin explained carefully, and Li Yu listened carefully, but how much he can master in the end depends on his understanding, in a mysterious and mysterious sentence, it depends on creation.

At five o'clock in the afternoon, Su Qin stood up from the boat and said while massaging his stiff muscles: "Okay, that's all for today's training, let's come back tomorrow." ”

Li Yu got up after hearing this, and sighed while packing up his equipment: "Squad leader, today is really better than listening to your words for ten years, because I have liked snipers since I was a child, I have read a lot of books on related aspects, but today I found out that I still don't understand bullshit." ”

Su Qin replied lightly: "So you have to practice more, think more, and read more!" ”

"But I've also read it, I've read hundreds of books, why don't you have this ability?"

"You also call reading? Is that what you call browsing? Turning the book open and going through it from beginning to end, is this called reading? True reading is to criticize and analyze, to remove the dross and retain its essence. ”

Li Yu was stunned: "But didn't the captain say it?" Soldiers can't have their own minds, so ......"

"You are wrong, it's not that soldiers can't have thoughts, it's that the army can't have ideas, but soldiers, especially modern soldiers, must have their own thoughts!"

After speaking, Su Qin stood up.

"Alright, that's all for today, let's go, go ashore, go home."

When the two of them returned to the extra-large area, it was already six o'clock, and they were all about to eat.

When the instructor saw the two of them coming back, he specially stopped Li Yu and asked, "How is it, have you gained anything from today's training?" ”

"Report to the instructor, there is!"

"Oh!"

The instructor's eyes lit up.

Then he asked, "Then tell me, what have you gained today?" Oh, by the way, how many bullets have been fired today? The result? ”

Li Yu straightened up and replied solemnly: "Report to the instructor, we didn't go to the shooting range today, we went to the small lake for training, so there was no live shooting." ”

"Huh?"

The instructor frowned.

Then he asked, "So how do you train?" ”

"Report to the instructor, the main thing is that the squad leader taught me how to look at the wind direction, how to fix the wind deviation, and how to measure the distance."

Li Yu concisely said all the things that Su Qin taught him.

The instructor listened and did not speak for a long time.

Li Yu waited for a long time and didn't hear a sound, so he couldn't help but feel a little strange, and turned his head to look at the instructor: "Teach...... Instructor? ”

Hearing his voice, the instructor came back to his senses.

He didn't speak, just waved his hand to signal that Li Yu could go.

Li Yu had been walking for dozens of seconds, and the instructor was still standing motionless, and after a while, he suddenly turned around and walked quickly into the office of the captain of the extra-large major.

"Report!" He shouted.

"Come in." The captain said.

The instructor walked in, but found that there was another person inside, a mountain knife, but everyone was more familiar with it, so he didn't shy away from it, and immediately said what he was thinking, and finally said: "Captain, I don't think this Su Qin is simple, he has only been in the army for two years now, but he has this level, this is still his own practice and self-learning, if you come to our special university to temper it...... Captain, if possible, I suggest you have to get him in! This little guy - not simple, really not simple! ”

Before his words fell, the mountain chopper sitting next to him pouted: "What can be not simple?" It's nothing more than a verbal theorist, and a real sniper doesn't just read a few books. ”

The instructor and the captain looked at the chopper in amazement.

This guy!

Thick unconvinced!
