The Red Alert Begins in the Wasteland

　　 After breakfast, when Cai Ruichen walked out of the base carrying an SVD sniper rifle, Natasha was already here waiting for him.

　　 After seeing Cai Ruichen coming out and bringing all the sniper equipment, Natasha also took out the majesty of being an instructor and asked Cai Ruichen to follow her and walk towards the big mountain on the left.

　　 After half an hour, the two stopped on the mountainside near the outside of the valley.

　　 "Commander, do you plan to learn how to be a good sniper, or just learn how to counter sniper?" Natasha asked Cai Ruichen on the mountainside.

　　 "Since I'm all studying, I plan to put in sweat and effort, so I naturally have to learn the whole set. And I don't want to be abused all the time in virtual reality." Cai Ruichen shrugged, seemingly indifferent, but his tone was very firm.

　　 "Then I will teach you the most comprehensive sniper tactics." Natasha suddenly turned to Cai Ruichen and asked, "Then what do you think as a sniper, you must learn first?"

　　The latter thought for a while and said, "Pretend?"

　　 Natasha shook her head, waiting for him to continue guessing.

　　 "Accurate shooting?"

　　 shook his head again.

　　 "Patience?"

　　 still shaking his head.

　　 "Sixth sense?"

　　 After listening to four answers in a row, none of them was the answer. Natasha could only say: "Ranging, that is, measuring the distance, and it does not rely on any equipment to calculate the distance to the target based on experience and eyesight."

　　 "Uh, what's the use of this? Which sniper doesn't have a professional binoculars now. The binoculars know it by looking at it." Cai Ruichen asked.

　　 Natasha shook her head and said, "Although the equipment is advanced, it is not absolutely infallible. On the contrary, my own experience and long-term training are the most trustworthy.

　　 Excellent snipers often perform sniper missions that go deep into the rear. What if the equipment is lost? Moreover, in a real battlefield environment, everything will happen, let alone a telescope. What if the observer dies? "

　　 After hearing Natasha’s words, Cai Ruichen realized that he had taken it for granted, and asked from the perspective of a student: "How do I start learning?"

　　"The method is very easy. First of all, you must understand the distance of one hundred meters. If there is an unknown distance, just calculate how many hundred meters can be put down to know the approximate distance.

It should be noted that if the terrain is upward, you will have the illusion of a little farther away, if the terrain is downward, it will produce the illusion of a little closer. The disadvantage of the 100-meter unit measurement method is that you can only work on a relatively flat terrain. Will get a more accurate measurement, which is particularly important for measuring long distances.

　　 If the target is one hundred meters or one hundred meters away and the sniper can only see part of the terrain between the target, the 100-meter unit measurement method cannot be accurate in this case. "

　　 Natasha's words, speak slowly, let Cai Ruichen hear them as clearly as possible and write them down.

　　 Cai Ruichen is also very serious. After all, there are teachers like Natasha, and few people in the world have such treatment.

　　 After Cai Ruichen asked some unclear points, Natasha started to introduce another measurement method-the standard appearance measurement method.

　　This method uses the true size and characteristics of the target to measure the distance to the target.

To put it simply, for example, a driver does not need to know the true distance between him and the vehicle in front to safely pass it from a sufficient position. Assuming that the driver knows how long a kilometer is, there is an oncoming one. The car is 3 cm high and 4 cm wide, and the two front lights are 3 cm apart. When he sees a car of the same size next time, he will know that the distance between him and the car is one kilometer.

　　This method can also be used by snipers to measure distance. By paying attention to some people or objects at a known distance, the distance can be determined by comparing their size and characteristics at an unknown distance.

When using the target appearance measurement method, the sniper must be very clear about the size and characteristics of the object at different distances. For example, the sniper records the size of the next person standing at a distance of 100 meters, and then records the person half kneeling at the same distance And the size of the squat.

　　 If you repeat observations from one hundred meters to five hundred meters, the sniper will naturally establish a set of distance observation skills. The sniper also needs to practice with other objects or vehicles.

　　 There is no requirement for this method, but the sniper must have good brain image memory ability.

　　 is also an ability that almost every sniper must possess. It is a basic introductory course.

　　 Under Natasha's detailed explanation, Cai Ruichen listened very carefully. In the explanation, Natasha also talked about her own opinions from time to time and gave him some vivid examples.

Only when Cai Ruichen felt that she already knew everything and only needed to train well, Natasha went on to say: "In a good environment, either the 100-meter unit measurement method or the target appearance measurement method is feasible, but on the battlefield A good environment is unique."

　　 "That's as you said, if there were no tools and the observer was killed at that time, what should I do?" Cai Ruichen frowned.

　　" So the sniper needs to mix the two methods. Terrain will limit the measurement method of 100 meters and the visibility will also affect the appearance of the target.

　　 For example, a sniper cannot clearly see the terrain between the target, but he has enough visibility to estimate the distance.

　　Even if the target looks blurry, the distance can still be measured by the size of its appearance. So only need to mix the two methods, an experienced sniper can get 90% accuracy. "Natasha said.

　　 When I heard that an experienced sniper was only 90%, Cai Ruichen asked curiously: "What about you?"

　　 "99.99%." Natasha said bluntly, "As long as there is no barrier, I can see the target four kilometers away, and also understand the changes in the distance between each section of ten meters within the four kilometers."

In addition to these two words, Cai Ruichen doesn’t know what words to use to describe Natasha’s impression in his mind~www.wuxiaspot.com~ Although he wants to achieve that level in his mind, Cai Ruichen knows very well. It is impossible for himself, at least he does not have such a perverted visual distance.

　　 Natasha didn't know that in Cai Ruichen's mind, he had become a seductive beauty and a super abnormal, but even if he knew it, it was still like that.

Natasha continued: "Tell you how to use the scale of the scope to calculate the distance to the target. This method requires a scope or telescope with a millimeter scale to observe. The height of the target on the scale is used to calculate the distance to the target. The distance of the target, the calculation equation is fixed.

　　 We must first know or judge the true size and height of the target in advance, and then multiply by one thousand and divide by the size of the target on the scale (mm), which is equal to the distance of the target. "

　　 "It seems that there is still equipment to make it easier." Cai Ruichen smiled inexplicably after hearing the last way.

　　 "That's for sure, otherwise what to do with those things, since they are invented, naturally they have to be used." Natasha said dismissively.

　　 "After the theory is finished, which one should I start training from?" Cai Ruichen asked.

Natasha said bluntly: "Starting from the visual inspection, you first remember the length of the 100-meter distance and the difference in the length in each environment, and give you one morning. If you cannot reach 80% by visual inspection. You are not suitable for being a sniper either."

　　 "I will leave you speechless." Cai Ruichen smiled confidently and said.
