Are you talking about playing Crysis or surviving in the wild? These two problems are different. How to survive when playing Crysis: always pay attention to the ammunition reserve of the weapon, and pick up some bullets every time you kill someone. You must know that there are many times when there are not enough bullets, so save some bullets when attacking. I won’t mention the specific shooting skills that make good use of the nano armor mode: when you are almost out of health, use stealth mode to hide aside and recover by yourself when fighting melee, use power mode (maximum strength) when jumping to high places, and use speed mode (maximum) when escaping. speed), etc. Wild survival skills with many uses: (I searched online, this is relatively complete)
Wild survival means people survive in the mountains and jungles with no accommodation. Special forces, scouts, airborne troops, and marines who go deep behind enemy lines, as well as soldiers and air crews who lose contact with their troops during the battle, in isolated enemy rear areas or in unfamiliar wilderness jungles and isolated islands, where instruments are cut off. Under such circumstances, bottom-up skills in the wild are even more needed. Here are some simple common sense for survival in the wild.
1. Use natural features to determine direction
In the absence of standard equipment such as topographic maps and compasses, soldiers must master some methods of using natural features to determine direction.
It is very simple to use the sun to determine the direction
You can use a benchmark (straight pole) to make it perpendicular to the ground, and place a stone at the vertex A of the shadow of the benchmark; about 10 Minutes later, when the vertex of the benchmark's shadow moves to B, place another stone. Connect two points A and B into a straight line. The direction of this straight line is the east-west direction. The direction perpendicular to the line AB is north-south, and the end facing the sun is south.
Use an analog watch to determine the direction of the sun. The method is: place the watch horizontally and halve the time indicated by the hour hand (in a 24-hour format), facing the sun. The direction indicated by the 12 o'clock scale on the dial is roughly north. If the current time is 16 o'clock, the 8 o'clock scale of the watch points to the sun, and the 12 o'clock scale points to the north.
When the weather is clear at night, you can use the North Star to determine the direction. To find the North Star, you must first find the bear constellation (what we call the Big Dipper). The constellation consists of seven stars that begin like a spoon. After finding the Big Dipper, follow the line connecting the two stars A and B on the side of the spoon and extend towards the mouth of the spoon about 5 times the distance between the two stars A and B. The brighter star is the Polaris. The direction pointed by Polaris is north. You can also use the Cassiopeia constellation opposite the Big Dipper to find the North Star. The Cassiopeia constellation consists of 5 stars that are about the same brightness as the Big Dipper and are shaped like a W. Polaris can be found in front of the middle of the W-shaped gap, about twice the width of the entire gap.
Using surface features to determine orientation is a supplementary method. When used, it should be used flexibly according to different situations. Freestanding trees usually have leafy southern foliage and smooth bark. The annual ring lines on tree stumps are usually thinner in the south and denser in the north. The doors and windows of rural houses and the main entrances of temples usually open to the south. Snow on buildings, mounds, field ridges, and highlands usually melts faster in the south and slower in the north. The south side of large rocks, mounds, and big trees is densely covered with vegetation, while the north side is prone to moss.
When you lose your way in the wild, do not panic, but stop immediately, always calmly recall the path you have taken, try to re-orientate according to all possible signs, and then try again. Find the way. The most reliable method is to "find your way back" and return to the original starting point.
After losing your way in the mountains, you should first climb up and look far away to judge which direction you should go. You should usually walk in a low-lying direction so that you can easily encounter water sources. It is safest to walk along the river. This is especially important in the forest. Because roads and residential areas are often built along waterfronts.
If you encounter a fork in the road and there are many roads that make you confused, you must first clarify the direction you want to go, and then choose the correct road. If several roads have roughly the same direction and cannot be determined, you should take the middle road first. This way you can get the best of both worlds, and even if you go the wrong way, you won't deviate too far.
2. Traveling Methods on Complex Terrain
When traveling in mountainous areas, in order to avoid losing direction, save energy, and increase travel speed, you should strive to have roads that do not go through the forest and cross the mountains, and there are roads that do not need to be walked. For trails, if there are no roads, you can choose to travel on longitudinal mountain ridges, ridges, mountainsides, edges of rivers and streams, and terrain with tall trees, sparse forests, large gaps, and low grass. We must strive to walk across the bridge rather than across the ditch, and to walk vertically rather than horizontally.
When traveling, take long strides rather than small steps. In this way, after dozens of kilometers, you can save more than ten thousand steps. When tired, use slow, relaxed steps to rest without stopping. When climbing rocks, you should carefully observe the rocks, carefully identify the quality and weathering degree of the rocks, and determine the direction and route of climbing.
The basic method of climbing rocks is the "three-point fixation" method, that is, fixing two hands and one foot or two feet and one hand, and then moving the remaining hand or foot to move the body's center of gravity upward. The hands and feet must cooperate well to avoid moving two points at the same time. They must be steady, light and fast. Choose the most appropriate distance and the most stable fulcrum according to your own situation. Do not take long steps or grab or pedal too far away.
Climbing hillsides below 30 degrees can be done in a straight line.
When climbing, lean forward slightly, put all your feet on the ground, bend your knees, and make your feet appear in an outward "figure of eight" shape. Don't step too big or too fast. When the slope is greater than 30 degrees, a zigzag climbing route is generally adopted. When climbing, bend your legs slightly, lean your upper body forward, put your inner toes forward, touch the entire sole of your foot on the ground, and turn your outer toes slightly outward. If you accidentally slip while walking, you should immediately face the hillside, open your arms but straighten your legs, raise your toes, and move your body up as much as possible to reduce the speed of sliding. In this way, you can try to find climbing and supporting objects while sliding. Never sit facing outwards, as this will not only cause you to slide faster, but may also cause you to roll over on steeper slopes.
Rivers are frequent obstacles in mountainous and plain areas. When encountering a river, do not rush into the water. Observe carefully before determining the location and method of crossing the river. Mountainous rivers usually have fast currents, low water temperatures, and rugged river beds. When fording, in order to maintain body balance, you should use a meridian to support the upstream direction of the water, or hold a stone weighing 15 to 20 kilograms in your hand. When wading in a group, three or four people can line up, hug each other's shoulders, and the strongest person is in the upstream direction.
3. Methods of gathering food
There are two main ways to obtain food in the wild. One is hunting wild animals, the other is collecting wild plants.
To hunt wild animals, you must first know the animal's habitat and master the animal's life patterns, and then hunt by methods such as trapping, snaring, trapping, and shooting. This requires a long period of training and practice under the guidance of experts to truly master it. The following is a brief introduction to the types and eating methods of edible insects and edible wild plants.
Currently, the insects that people in the world eat include snails, earthworms, ants, cicadas, cockroaches, crickets, butterflies, locusts, grasshoppers, lake flies, spiders, mantises, etc. Although people are not used to eating insects, and may even feel disgusted with it, they still try it as a last resort in order to maintain their lives, maintain their combat effectiveness, and complete their tasks. However, it should be noted that the food must be cooked or roasted thoroughly to prevent parasites from the insects from entering the human body and causing poisoning or illness.
Common edible insects include locusts; dipped in soy sauce and eaten roasted, boiled or stir-fried; mantis: roasted or stir-fried after removing its wings, or boiled; dragonfly: edible after dry frying: cicada : Eaten raw or dry-fried, the larvae can also be eaten; Centipede: Dry-fried, but the taste is not good; Longhorn beetle: The larvae can be eaten raw or roasted; Ant: Fried, delicious; Spider: Remove the legs and roasted; Termites: Can be eaten raw Or fried food; pine caterpillar: grilled food.
Edible wild plants include edible wild fruits, wild vegetables, algae, lichens, mushrooms, etc. The identification of edible wild plants is a staple of bottom-up knowledge in the wild. Our country has a vast territory and is suitable for the growth of various plants, of which about 2,000 are edible. Common edible wild fruits in my country include: mountain grape, tusi, black blind fruit, strawberry, sea buckthorn, torch fruit, myrtle, elegans, black rice tree, amla, etc., especially wild chestnut, coconut, papaya Easier to identify and a great emergency survival food. Common wild vegetables include bitter greens, dandelions, Houttuynia cordata, purslane, amaranth, shepherd's purse, wild amaranth, broom greens, water chestnuts, lotus, reeds, moss, etc. Wild vegetables can be eaten raw, stir-fried, cooked or by boiling and soaking.
However, the average person needs a certain period of training under the guidance of experts to master this knowledge. Here is the simplest method to identify whether wild plants are poisonous or not, for use in emergencies. Usually, a small opening is cut into the collected plants, a pinch of salt is put in, and then the original color is carefully observed to see if it changes. Usually, discolored plants cannot be eaten.
4. Methods of Obtaining Drinking Water
There are usually two ways to obtain drinking water: one is to dig underground water, and the other is to purify surface water. We only introduce methods of obtaining drinking water from surface water.
Usually rainwater can be drank directly. When it rains, you can use ponchos, plastic sheets to collect rainwater in large quantities, or you can use empty cans, cups, helmets and other containers to collect rainwater.
When there is no reliable drinking water and no inspection equipment, the quality of the water can be roughly identified based on the color, taste, temperature, and water traces of the water. Pure water is colorless and transparent when the water layer is shallow, and light blue when it is deep. You can use a glass or white porcelain cup to hold water for observation. Generally, the clearer the water, the better the water quality, and the turbid water means more impurities. Generally, clean water is odorless, while polluted water often has some odor. The water temperature of surface water changes due to changes in air temperature. The shallow underground water is less affected by air temperature, while the water temperature of deep underground water is low and constant. If the sampled water does not comply with these rules, there is generally a problem with the water quality. In addition, you can also use a piece of white paper, drop water on it and let it dry before observing the water marks. Clean water has no stains. If there are stains, it means there are impurities in the water and the water quality is poor.
It is best not to drink water flowing from weeds in the wild, but to drink clear water flowing from cliffs or rocks. When drinking water from rivers or lakes, you can dig a small pit in the sand 1 to 2 meters away from the water's edge. The water seeping out of the pit is cleaner than water extracted directly from rivers and lakes.
In the wild, you can use drinking water disinfectant tablets, bleaching powder tablets, alum and other drugs to purify water. Under the guidance of experts, some wild plants containing mucilage can also be used to purify water. Remember, no matter how much you drink, do not drink unclean water. As a last resort, boil the water before drinking it.
5. Prevention and treatment of common injuries and illnesses in the wild
Prevention and treatment of insect bites: In order to prevent insect bites in the wild, personnel should wear long-sleeved clothes and trousers, and tighten their cuffs and collars. , apply mosquito repellent on exposed parts of the skin. Do not sit or lie in moist shade trees or grass. When camping, burn mugwort leaves, mugwort, cypress leaves, wild chrysanthemums, etc. to drive away insects. After being bitten by an insect, you can use ammonia, soapy water, salt water, baking soda water, and zinc oxide ointment to smear the affected area to disinfect the itchy area.
Leeches are very harmful insects. When you encounter a leech bite, do not pull it out by force. You can pat it with your hands or drop soap, salt water, tobacco oil, or alcohol on its front suction cup, or burn it with a burning cigarette to let it fall off on its own. Then apply pressure on the wound to stop the bleeding, and use Apply iodine to the wound to prevent infection. When the troops are marching, they should always check whether there are any leeches crawling on their feet. If you apply some soap and anti-mosquito oil on your shoes, you can prevent leeches from crawling on them. The effective time after one application is about 4 to 8 hours. In addition, applying garlic juice to shoes, socks and trousers can also play a role in repelling leeches.
Fainting in the wild is mostly caused by falls, excessive fatigue, excessive hunger and other reasons. The main symptoms are sudden paleness, weak and slow pulse, and loss of consciousness. Don't panic when this happens, you will usually wake up after a while. After waking up, you should drink some hot water and pay attention to rest.
Poisoning: The symptoms are nausea, vomiting, diarrhea, stomach pain, heart failure, etc. In this case, you should first wash your stomach, drink a lot of water quickly, touch your throat with your fingers to induce vomiting, then take laxatives such as castor oil to clear the intestines, and then take detoxifiers such as activated charcoal and other sedatives, drink more water, and Accelerate excretion. In order to ensure the normal beating of the heart, you should drink some sugar water and strong tea, warm your feet, and send to the hospital for treatment immediately.
Heat stroke: Symptoms include sudden dizziness, nausea, coma, no sweat or clammy, dilated pupils, and high fever. Before the onset of the disease, I often felt dizzy from drinking, felt weak all over, and my eyesight turned black. At this time, Qing immediately lay down in a cool and ventilated place, untied his clothes and pants, relaxed his whole body, and then took Shidishui, Rendan and other medicines. When you have a fever, you can pour cold water over your head or apply cold compress to dissipate heat. If you are unconscious, you can pinch Renzhong and Herong points to revive you.
Frostbite: If the skin is red, white, cool, hard, etc., rub the injured area with your hands or a dry cloth to promote blood circulation and reduce frostbite. Use chili pepper for mild frostbite. Soaking it in wine and applying it will be effective. If the body is frozen, do not immediately carry the injured person into a warm room. You should first rub the limbs and perform artificial respiration. After the injured person regains consciousness, go to a warmer place for rescue.
Stings: Stings caused by poisonous insects such as scorpions, centipedes, and wasps cause red, swollen, painful and itchy wounds, accompanied by symptoms such as nausea, vomiting, and dizziness. First squeeze out the venom, then apply soapy water, ammonia, tobacco oil, vinegar, etc. to the wound, or mash purslane, drink the juice, and apply it externally. You can also wash and pound the snails, then mash them and apply them on the wounds. In addition, garlic juice is effective in treating centipede bites.
