Snow Wolf then picked up a piece of clothing and said, "Do you recognize this? You guys probably love this when playing games. That's right, this is a camouflage suit (also known as a Ghillie suit). It originated 200 years ago with a Scottish gamekeeper, the Ghillie suit. He created a successful camouflage suit to ambush and monitor illegal hunters, and he obtained the intelligence he wanted. Today, there are roughly three types of Ghillie suits, each used in different situations and environments.
Type: Coverall with separate pants and rain cover (camouflage cloth) The selection method is as follows: First consider the size of the concealed area. Then consider the climate and environmental factors of the hiding area.
1. Coveralls. Camouflage clothing made of one-piece coveralls can provide full-body concealment and prevent insects and ants from crawling into the camouflage clothing. The disadvantage is that the weight of the full-body concealment is concentrated on the shoulders, which adds a certain amount of resistance when crawling on the ground.
2. Separate camouflage clothing. Separate camouflage clothing is more flexible. When snipers are hiding in strongholds, they often only need to conceal their head and upper body. Separate clothing allows the lower body to remain flexible and reduce the feeling of encumbrance.
3. Rain cloak (camouflage cloth). This type of camouflage clothing is ideal for snipers huddled in a stronghold, completely concealing their silhouette. Its greatest advantage is its lightness and flexibility.
In fact, a sniper's first rule of survival is to remain undetected. To improve intelligence gathering efficiency, armies often deploy single or paired snipers, concealed in high positions as defensive strongholds. Snipers also utilize monoculars or binoculars to identify targets and a receiver-like radio to support intelligence operations. Furthermore, snipers employ camouflage, unusual approaches, and frequent, slow movements to deceive the enemy, shielding them from precise counterattacks. Some snipers can achieve undetected kills at distances of less than 90 meters. This demonstrates the importance of camouflage to snipers.
After that, everyone was confused. It turned out that there were so many tricks to camouflage. Someone asked, "Instructor Snow Wolf, I'd like to ask how to avoid infrared and thermal imaging detection."
Snow Wolf said: "1. To isolate the heat generated by the body, snipers in the wild usually add tin platinum under their clothes to isolate body temperature. This means that the body's temperature cannot be transferred to the surface of the clothes. In this way, there will be no difference in temperature within the field of view of the thermal imager, and the thermal imager will not be able to detect the sniper.
2. Using the propagation direction of infrared radiation, we all know that light propagates in a straight line, and infrared thermal imagers can only form temperature images by capturing the invisible light generated by objects, that is, infrared radiation. Therefore, infrared thermal imagers cannot actually penetrate walls, stones, doors, etc. Behind walls or behind obstructions, thermal imagers cannot detect target objects.
3. Make your own temperature consistent with the surrounding temperature, because thermal imagers detect by receiving infrared radiation of different energies emitted by the surface of the object. If the human body temperature is consistent with the surrounding temperature, for example, you can hide underwater, then the thermal imager will not be able to detect it.
4. New technological materials. In 2014, Harvard University in the United States developed an active camouflage material that can mask its actual temperature in front of infrared thermal imagers. Its unique properties hold great promise for both military and civilian applications, marking a significant step forward in the development of active camouflage materials. The key to this active camouflage material lies in a very thin film of vanadium oxide. When it reaches a specific temperature, its electronic state changes, altering its conductivity and transforming it from an insulator to a conductor. During this transformation, its optical properties also change, emitting different colors of light depending on the temperature. This is a future method for evading thermal imaging cameras. However, I've heard from older generations that back then, without these technologies, they used the first method: covering their bodies in mud to isolate themselves from heat, making their location undetectable. However, this method rapidly dissipates body heat, making accidents highly likely. I wouldn't recommend this method unless absolutely necessary. However, they relied on their sheer willpower to complete their mission and return to base, but they also developed underlying health problems as a result. It's a shame.
Yes, the older generation used their bodies to create such good conditions for us. Now we have everything we want. We have what others have, and we also have what others don't have. So now there is no difficulty that we can't overcome. They could do it under those conditions, so why can't we do it under such good conditions now?
Snow Wolf continued, "Now let me show you how I disguise myself. I'll have two minutes to disguise myself. When the time is up, come find me and see how good your eyesight is. Blindfold your eyes now, and come back in two minutes."
Everyone closed their eyes when they heard that. They were all soldiers and would not do such small movements. They all closed their eyes honestly.
Snow Wolf was indeed a master of disguise, and he completed the disguise in no time. When the time was up, everyone slowly opened their eyes.
In fact, Xiang Jingtian knew the location of the snow wolf with his eyes closed, because he had a detection radar. In front of the detection radar, all disguises were illusions, and it could see you even if you hid underground.
Xiang Jingtian looked towards the Snow Wolf's position at a glance. The Snow Wolf also noticed Xiang Jingtian looking at him at this time, but he believed that his disguise skills were absolutely fine, so he didn't take it to heart.
But who would have thought that Xiang Jingtian actually used sign language to give him, which meant that I have discovered you, but I don’t want to say it.
Xuelang had also learned sign language and understood the meaning of the sign language at a glance. He was extremely depressed now and kept thinking about whether he had missed anything.
In fact, he didn't miss it at all. Even if they were to find it for three days and three nights, he didn't know that Xiang Jingtian had a system. As long as you are within the range, I can find you.
So Xiang Jingtian joined everyone in the search.
