When it comes to snipers in games and movies, most of us will have such a scene in our minds - a gunman is hidden in places that others cannot detect, such as grass or broken walls of the city, waiting quietly for the enemy to appear. When the target entered the crosshair of the scope, he gently pulled the trigger, and the long barrel sprayed out deadly flames, and the enemy fell into a pool of blood. So, while holding his breath and concentrating, the sniper quietly completed the precise killing cleanly...
" Life and Death Sniper ": The dazzling "sniper feast"
The movie "Life and Death Sniper" released in 2007 can be said to be a "burning" movie. Although there are many exaggerated descriptions of the sniper's magical skills in the film, the weapons and tactics in them are generally reliable.
The famous Barrett M82A3.50 caliber reverse equipment sniper rifle
The video started out as a sniper battle. In dusty Ethiopia, the protagonist Bob Lee Swag and his observer ambush the enemy's armed convoy. What is impressive here is that Swag started with an M40A3 sniper rifle to shoot enemy armed personnel. After being discovered by a helicopter, his observer used a SOPMOD M4A1 assault rifle with M203 grenade launcher and red dot sight inside M2. The M203 is a grenade launcher set by the US military in the 1970s. It is usually installed under the barrel of an M16 or M4 rifle and can fire high-explosive bombs, smoke bombs, flares, CS gas bombs, etc.; the red dot sight inside the M2 is a Comp M series fast sight produced by Embosser, Sweden, without magnification. Later, in order to fight a helicopter, Swag took out the famous Barrett M82A3 .50 caliber reverse equipment sniper rifle. The Barrett M82 series is one of the most widely used large-caliber sniper rifles today, and the A3 is an improved Marine model based on the A1, with the Army model M82A1M. This passage in the video is as dazzling as a weapon demonstration. Some readers may ask, is it necessary to carry so many weapons? In fact, this equipment has some rationality. In reality, the main equipment of snipers includes pistols, bolt-moving or semi-automatic sniper rifles, ammunition and camouflage equipment; while the main equipment of the observation hand includes pistols, fully automatic or semi-automatic rifles, camouflage and observation equipment. In addition, let’s talk about the plot of the protagonist shooting down a helicopter with a Barret rifle. This is actually difficult to achieve in reality, because the helicopter does not need to fly so low to let the sniper fight back, and it can completely solve the battle with a machine cannon at a long distance. The Barrett anti-equipment sniper rifle is characterized by its powerful power, certain armor-piercing ability, and is not known for its accuracy. The probability of directly hitting the helicopter rotor shaft is slim. Moreover, several fragile parts of the helicopter: such as rotor shaft, rotor, cockpit, fuel tank, engine and hydraulic system are all specially strengthened or dual backups. Taking the Russian-made Mi-17 transport helicopter as an example, its rotor shaft can withstand the strikes of 20 rounds of 7.62 mm bullets or 3-5 rounds of 12.7 mm bullets. Not to mention specialized armed helicopters.
The Cheytac Intervention M200.408 caliber long-range sniper rifle that appeared at the Swag home and at the assassination site is part of the Chey Tac LRRS (Long Range Rifle System), which consists of the M200 sniper rifle, CheyTac special precision ammunition, ballistic computer and CheyTac ballistic software. Among them, the ballistic computer provides all necessary data for long-range shooting through sensors and internal ballistic databases, with a maximum range of up to 2,200 meters. The M200 sniper rifle uses a manual spinning rear-pull bolt. The scope is equipped with an NXS 5.5-22x scope produced by Ningtforce. This gun maintains the world's furthest shooting hit record of 2321 yards. Unfortunately, the advanced long-range sniper rifle in the film only fired one shot at the beginning of the film - hitting a can. In addition, the negative character has also used the TR250D remote control weapon station to operate this rifle.
Swag used the Merlin 5.6mm small-caliber rifle and Remington M700P sniper rifle respectively.Among them, the 5.6mm small-caliber rifle bullet used by the former is called "Point 22LR rifle long bullet" in the United States. It is a common traditional civilian bullet. It is the most commonly used competition and training ammunition for various 50-meter sports rifle shooting events. It is also a type of ammunition widely used by foreign Boy Scouts, middle school shooting teams, etc. to carry out youth shooting activities (so Swag calls this rifle "children". It uses a bare lead warhead, a brass cartridge with a rim on the edge, with an extremely simple structure and very cheap price. To reduce gunshots, Swag uses a simple muffler. He used the plastic bottle as a carrier and filled the inside with white flocs. Considering that Swag's rifle has a small caliber, this simple sound silencing device is still effective, at least it can cushion the airflow at the muzzle. However, such a simple equipment is useless if it only takes a few shots, because the filling will fail due to burning and deformation.
M700P is a police model of the M700 series, and the use of a thickened floating barrel further improves the accuracy. Because the weight of the entire gun increases, the recoil is also reduced. In the snow sniper battle at the climax of the film, the M700P used by the three villain snipers are all ordinary types that fire 7.62mm NATO bombs, equipped with a 10x scope and a two-point stand. The M700P used by Swager is the model that fires 7.62x67 Winchester's powerful gun bullets. This ammunition charge and power are even stronger than the Russian 7.62x53R machine gun ammunition, with an initial velocity of 902 meters per second, and its ballistics are very straight, with an effective range of 1,000 meters, which is a full 200 meters higher than the ordinary M700P.
video game "Battlefield 4", in this game, the manufacturer simulates the details of the initial velocity of ammunition and the weight of warhead
Sniper in the game: ignore the influencing factors
First, let’s briefly introduce what factors are affected by long-distance sniper in reality. In addition to the subjective factor of the shooter's own shooting skills, there are also a large number of objective factors that will affect the flight trajectory of the bullet, which in turn will affect the shooting accuracy. First of all, the most obvious thing is the gravity of the earth, which will gradually pull the warhead toward the ground, so the ballistic formed by the warhead is a parabola rather than a straight line. The second is the combined effect of wind speed and wind power, collectively known as "wind bias". "Wind deviation" will greatly affect the stability of warhead flight. In addition, changes in air density and humidity will also affect the warhead's flight trajectory. Earth's rotation and Earth's magnetic field will also have a weak impact on warhead flight during ultra-long-distance sniping. Moreover, the warhead itself rotates, and this rotation will cause the ballistic to slightly deviate when the warhead flies to a certain distance. The quality and performance of the sniper rifle itself will also affect the ballistics. The temperature changes of the emitted drug will affect its combustion rate, which will in turn affect the initial velocity of the warhead, and will also affect the ballistic stability. The quality of the warhead itself will also affect the shooting accuracy.
Therefore, snipers in computer games greatly simplify the difficulty of shooting sniper rifles, just as an entertainment. Take Battlefield 4 as an example, although this game makes the details of the difference in ammunition velocity and warhead weight. However, in reality, no matter which sniper rifle is used in the game, you can barely achieve a straight ballistic when hitting a target of 100-300 meters. However, as long as you pass 300 meters, the rifle's bullet will drop sharply, especially those short-range sniper rifles. If you do not adjust the position of the scope or adjust the tight position according to the shooting distance, it will be difficult to hit the target, let alone shoot the head like the game.
In comparison, the " Sniper Elite " series of games are more realistic. Adjusting to high difficulty, the sniper rifle in this game no longer refers to wherever you hit, but requires you to calculate the bounce point based on the wind deviation meter and the distance to the target. But even so, this game still simplifies a lot of things, such as the Earth's magnetic field and bullet rotation.
Most shooting games on the market have reduced the difficulty of sniping under real conditions to the extreme, such as CS, "Cross Fire" and " PlayerUnknown's Battlegrounds " (commonly known as "Chicken Eating"), etc. These games rely solely on crosshairs to aim and ignore shooting distance, simplifying cumbersome but necessary steps including ranging, adjusting tight positions, and calculating ballistics.
In short, due to the public's admiration and yearning for the sniper's ability to kill one-hit, snipers will be active in the screen and virtual world for a long time in the future, continuing to perform their fabulous legends.
