Danielle came back to his senses after a while, and smiled awkwardly: "It's nothing, we will definitely cooperate well." Then his expression darkened, "It's just that Ayiguzali's mother is going to be disappointed again." ”

Yang Luo said: "I will still buy the stone of Ayiguzali's mother." ”

Danielle's eyes lit up, but he just nodded and didn't say anything. In fact, the villagers here are very simple, there are not so many intrigues, in their hearts, the People's Liberation Army is the most trustworthy, although they have just been deceived once, but it is not malicious.

"Bang Bang Bang ......"

Yang Luo slapped his face, "Okay, fellow countrymen, we need your clothes, okay?" ”

Danielle said, "Yes! ”

"Change your clothes!" Yang Luo shouted, and everyone found a fellow with a similar figure and changed their clothes. Then everyone found a few thick cotton hats to fasten their heads, covering half of their faces.

Yang Luo glanced up, Hongye was not finished yet, there were two girls who were curling her hair and wearing jewelry, and the two girls had been babbling something, although she couldn't understand it, but looking at the eyes and movements of the two people, she must be praising Hongye for her beauty.

After five or six minutes, Momiji spun around in place, giggled and said, "How is it, I can't drift beautifully?" ”

Yang Luo pursed his lips and said to Nu 1 Erdong: "Brother, take us to their station!" ”

Nu 1 Erdong nodded helplessly, turned around and walked out.

Yang Luo patted the soldier on the shoulder: "Don't break the rules of the exercise, stay here honestly." ”

A few people came out of the house, and Nu Erdong was about to walk to the door, Yang Luo pressed his shoulder, "Xu Hang, the one in charge of defending the electronic countermeasures detachment must be a reinforced squad, a sniper, and a heavy fireman." You go find the snipers and take them out, and when we do, take out the heavy fireman. ”

"Yes!" Xu Hang jumped under the earthen wall in one step, then stuck to the root of the wall, bent down and quickly jumped out of the gate, and disappeared in front of everyone's eyes in the blink of an eye.

Wang Huan, Shen Hao and Wu Ke were a little unconvinced, snipers and heavy firefighters must be at the commanding heights, not to mention whether they can find the hidden location of others, in broad daylight, won't they be discovered by others when they go out?

Yang Luo glanced back at the three of them, how could he not know what they were thinking: "Do you know what visual camouflage is?" ”

"Yes!" "It's a compulsory subject for us, especially as a sniper. ”

"Oh?" Yang Luo raised his eyebrows, "Then tell me, what is visual camouflage." ”

Wu Ke opened his mouth, they did often conduct camouflage training, but these were all done according to the requirements of the training subject list, if he was asked to say one, two, three, four, it would be a bit difficult for him.

Wang Huan said suddenly: "Visual camouflage is to use the surrounding environment to camouflage colors, for example, this time we wore snow camouflage and a white cloak, as long as we lay on the ground, it will be difficult for the enemy to find us." ”

Yang Luo smiled slightly: "Human vision, in principle, is the result of the cooperation between the eyes and the memory cells of the brain. The eye transmits images of the surface of the object it sees to the brain, and then determines what it is, which is what we usually call first vision.

And your so-called camouflage is the simplest, and it can deceive those rookies, and a real master, when observing and capturing the target, will search through the second vision, that is, the outer edge of the contrast between the color and the shape of the surrounding objects. In layman's terms, when they arrive at a certain area, they will immediately form a simulated image of the surrounding environment, which I call a mental image. Then the brain will involuntarily look for a target, compare the image in the field of vision with the image of the mind, if there is a certain difference, they will further observe and analyze, this time is definitely not too long, maybe only a few seconds, and then they will shoot without hesitation. ”

Wang Huan muttered: "How is this possible, it's incredible." ”

Yang Luo said: "Nothing is impossible, any contour will be very obvious in a high-contrast or smooth background, a piece of white cloth is like deceiving everyone's eyes, what about your dreams?" A true master, their understanding of the human body, the recognition of the shape and contour of objects, as well as the ability to capture, as well as the ability to instinctively intuit are very amazing, only by breaking their mental image, can they truly make themselves completely invisible! ”

"So how can you better hide yourself from the eyes of your enemies?" Wu Ke humbly asked, not only him, but also Wang Huan and Shen Hao did not doubt Yang Luo's words. After all, the name of the blood wolf, for them, is the existence of the god of war, and in the field of special warfare, it is definitely a godfather-level figure. If you don't take advantage of such a good learning opportunity, you will be really stupid, and it will be impossible to want such an opportunity in the future.

Yang Luo looked at the time and said: "The most obvious and important method of visual camouflage is to change or interfere with the external contour features of objects that human beings are familiar with, such as blurring the outer edge of the target, and the contrast of color can also change the brain's judgment of the contour of the object, so that the observer cannot compare the external contour of the object with the simulated image in his mind, thereby reducing the probability of being recognized." For example, in camouflage uniforms, many commanders do not have a sufficient understanding of the role of the patterns on camouflage uniforms, one-sidedly emphasize the neatness of the army, and require soldiers to wear new and straight camouflage uniforms to the battlefield. In fact, dusty or worn camouflage uniforms have a more practical concealment effect than new, crisp camouflage uniforms.

Therefore, we must know how to use various natural environments for camouflage, so we must have an understanding of the shape, color and density of vegetation in the mission area at the right time, grasp the laws of some wild plants, and use natural camouflage as much as possible. And many times it is not possible to change the camouflage according to the environment at any time and place during the march, so it is necessary to remember a basic principle, when the battlefield conditions do not meet the requirements for successful camouflage, try to use dark colors for camouflage. This is due to the characteristics of the human eye, which is much less sensitive to dark objects than to light-colored objects, and in most cases, light-colored objects are always the first to be detected. ”

"But ......," Shen Hao said hesitantly, "Now this environment is snowy, if you use dark camouflage, isn't it the opposite of the color of the surrounding environment, and it will be easy to be discovered?" ”

Yang Luo bent down and picked up two palm-sized stones and said, "You are staring at the snow on the ground for three minutes now!" ”

Shen Hao didn't know why, but he still followed Yang Luo's request, staring at the snow on the ground a few meters away. The rays of the sun in the sky shone on the snow, and the refracted light made his eyes a little uncomfortable. Three minutes later, Yang Luo threw two stones out. One fell in the shadow of the corner, and the other flew out more than twenty meters away and landed on a snowdrift outside the gate.

"Do you see those two stones?"

Shen Hao's eyes widened, he saw where the stone fell, but he didn't see the stone: "It's too dark there, I can't see it." Is the other stone in the snowdrift of the trap? ”

Wang Huan and Wu Ke's faces became very strange: "Shen Hao, you really can't see it?" ”

"Ahh Shen Hao sighed, "I saw it, what's going on?" ”

Yang Luo smiled slightly: "It's one o'clock in the afternoon, the sun is very strong, and there will be reflected light on the snow." When you stare at the snow, it causes a brief period of snow blindness, so you can't see the rocks that are so dark and not slippery. And the "enemy" has only one guard squad, so the sniper is also only one person, and he stares at his surroundings for a long time, which will definitely cause poor vision. ”

"Got it!" Shen Hao asked with some excitement, "But people are so tall and have to move, even if the "enemy" causes visual differences due to the environment, it is impossible not to find it." ”

Yang Luo said: "You're right, the image that moves and causes shaking is the easiest to detect, even if it is highly myopia, it can be found from tens of meters away. A normal person's eye field of view is very wide, reaching 150 degrees to the left and right, and a trained person can use the naked eye to detect a slightly moving enemy from a distance of 300 meters. A master can observe a moving human body from a distance of 500 meters. But a master of camouflage can be truly stealthy, even when on the move.

Generally, the contour lines of objects are the most obvious parts, but when these parts appear black, they will disrupt the outline of the human body and will not be easy to recognize. The head and shoulders of the human body are the most recognizable, so when camouflaging to change the lines of these appearances. But you have to remember that only man-made things have geometric shapes, and the shapes of natural combinations are very random, and geometric shapes rarely appear.

Therefore, a master of camouflage will reshape the head with dark soil, that is, the forehead, eye sockets, nose, ears, and some protruding and sunken parts of the chin will be filled with dark earth to break the original shape. Then the effective camouflage of the costume, and finally the use of light, it is completely possible to deceive the eyes of the "enemy". When the surrounding environment is particularly bright, the shadows will appear particularly dark, and this light and dark places form a very extreme contrast, and in this extreme contrast, it is difficult for the human eye to adjust the difference between light and darkness in two places at the same time...... In this way, whether you are squatting or curled up, it will be difficult for the "enemy" to find out if you are a person or a stone. ”

After speaking, Yang Luo looked at the time again, "Okay, Xu Hang's place should be over, it's time for us." ”

At this time, on the hillside of the village, there was a protruding rock, and a soldier in a white cloak was lying depressed. There was also a man sitting beside him, his entire head covered in black mud, revealing only his eyes, nostrils, and mouth, which were angular and irregular. The clothes on his body were also black and white, black was mud, and white was snow. If you don't look closer, he's a rock.

And the soldier never dreamed that he, as the best sniper of the guard company, would be touched by such a monster and did not find it, and then he was so strong that he had no chance to react at all. He couldn't figure out where this pervert came from, a few hundred meters away, he escaped his eyes and killed him.

Xu Hang smiled, and the mud on his face that was about to dry cracked piece by piece, but it didn't fall: "Boy, don't look bitter and hateful." Don't say it's you, even Sun Haiyang of the Tiger Regiment is not enough to see in front of me. ”

The soldier was not very old, and he was very unconvinced when he heard Xu Hang's words, and snorted coldly: "Don't talk big, if you met Captain Sun, he would have killed you with one shot." ”
