a tracer bullet is a kind of shell or bullet with a luminous chemical at its tail. Emit red, yellow or white light after emission. Used to indicate trajectory and target. The difference between tracer bullets and other bullet warheads is that the warhead will shine in flight, and show the trajectory when the light source is insufficient or dark, which helps the shooter to correct the trajectory and even serves as a way and tool to guide and contact the attack direction and position of friendly forces.

In early January, 213, Japan will raise the level of defense, and launch warning shots with tracer bullets on the vessels of the sea surveillance in Chinese mainland, including the aircraft of the sea surveillance, which will further worsen, intensify and escalate the situation on the Diaoyu Islands.

Catalogue Working Principle of Tracer Bullet Structure Tracer Bullet Type The operational function of Japanese provocative tracer bullet is unfolded
Edit the working principle of this paragraph Tracer Bullet (yèguāngdàn) Because the bullet tip has a layer containing flammable chemicals, For example, phosphorus or magnesium (magnesi tracer um) mineral coatings, so after being shot out of the barrel, the bullet head rushes through the atmosphere at high speed, and the bullet tip rubs against the atmosphere to form high temperature, which ignites these mineral coatings to make the bullet shine. [1] Edit the structure of this paragraph of tracer bullet. The tracer bullets of the United States and NATO basically indicate the trajectory with strontium mixed magnesium, and the combustion effect is formed through the combustion of magnesium; The so-called "armor-piercing incendiary ammunition" is to add this coating on the outer layer of copper-clad tungsten steel; Russia and China tend to use barium as the ballistic indicator color, that is, if the tracer is green in a war situation, it is a tracer from Russia or China; If it is bright red, it means that the warhead comes from the United States or NATO. The advantage of using tracer in combat application is that it can help the shooter to correct the aiming target in the light shortage or darkness. However, the two sides of the double-edged body will expose the shooter's position, so it will be hit back or escaped by the target. In view of this, ammunition manufacturers also put forward a new solution, that is, to reduce the amount of ammunition powder, by reducing the initial velocity of the warhead to "delay" the ignition of the flammable substance of the warhead, so that the tracer will start to indicate the trajectory after flying away from the muzzle for a certain distance. However, this world is always full of contradictions, because the tracer bullet, to put it bluntly, is made from ordinary solid all-metal coated warheads and phosphorus-magnesium coatings, which also has the same lethality. However, after the propellant is reduced, the warhead will be slightly reduced in power, muzzle velocity and effective distance. As tracer bullet is an effective aiming correction tool, it is also widely used. Before the main tank M196 tracer bullet used advanced shooting control instruments, such as infrared night vision device and laser pointer, it was often fired at the target through the co-axial machine gun next to the main gun, and the commander of the chariot observed the landing point through the aiming telescope, then corrected the aiming or destroyed the target with the main gun. Tracer bombs are also very important for air combat. For the P-38 fighter, the Hispano M2(C) 2 mm gun at the nose has 15 rounds of ammunition, including 2 tracer bombs, 2 armor-piercing bombs and 141 high-explosive bombs. The other four Browning M2 heavy machine guns add up to 1 ***2, rounds. One of the 5 BMG bullets is a tracer bullet on average, so in air combat, the pilot can correct the fuselage angle or speed with the trajectory of the tracer bullet so that the trajectory can meet the Japanese or German aircraft and shoot it down. Imperial japanese navy's general Isoroku Yamamoto is one of the spoils of the P-38 fighter (declassified after the war that General Yamamoto's body had a bullet wound with a heavy machine gun, showing that he had been killed by the machine gun of the P-38 fighter before the plane crashed and died in his seat). Another advantage of tracer bullets in air combat is to help the camera gun identify the results, whether it hits the enemy plane and whether it causes the enemy plane to burn or explode. Another less well-known is that the Soviet AK-47 assault rifle also relies heavily on tracer bullets; The importance of tracer in AK-47 is not to help the shooter to correct the trajectory, but the shooter often puts the tracer as the last shot in the magazine, which can remind the shooter that the bullet is exhausted and he has to stop fire and replace the magazine. The Soviet Air Force unwisely adopted similar arrangements in World War II, but it couldn't hide from the shrewd German pilots, because as long as the pilots survived the struggle, often that Soviet tracer bullet represented Germany's "Show time!" It's time (for the good show). The same is true of the shooting of tracer bullets for troops in ground combat; Even if the muzzle remains silent after a tracer bullet, it means that the clever enemy is either changing the magazine or running out of ammunition; Or it is a trick of showing weakness by strength, misleading the enemy into thinking that the other side is alone and desperate, and luring the enemy troops to annihilate them when they approach. [1] Edit the types of tracer bullets in this paragraph. According to their brightness, tracer bullets can be divided into three types: bright tracer bullets (4 pieces) sub-bright tracer bullets (dim tracer bullets). Basically, tracer bullets are enough when they are not used, and when they fly out of the muzzle, they are bright and bright, so they can "friendly" remind the warring parties where to launch tracer bullets. So there is a military proverb that says, "tracers work both ways.". Tracer can have how bright? Bright tracer can make night vision goggles unable to withstand brightness to the point of being sent for repair. The slightly bright tracer bullet is a kind of bullet developed to improve the shortcomings of the bright tracer bullet exposed to the shooting position. Usually, the warhead will not start to ignite until 1 yards after flying out of the muzzle. As for the luminosity of the dark tracer, its clarity is not as clear as that in the night vision goggles. On the contrary, the new patent tracer application creatively abandons the traditional pyrotechnic compound warhead and uses "light emitting diode" (LED) and capacitor. Its advantage lies in that only one's own side can see the tracing of the tracer bullet because of the backward shining directional light source, and it is almost impossible to go far, because the traditional tracer bullet is limited by the coverage of the mineral coating on the bullet tip, and it often happens in a long distance that the phosphorus and magnesium coating on the bullet tip has already burned out and lost its guiding effect. However, on the other hand, this kind of warhead is also quite heavy. Although it can shine continuously, it can't effectively break through the limit in range until it can't be further lightened. By the way, add some information, 7.62mm x 51 tracer or 7.62mmR tracer will fail after the range exceeds 8m; 5.56x45 NATO tracer or 5.45 M74 tracer will be invalid after 3m. The warhead of M856 tracer bullet weighs 63.7 grains, which can be used in M16A2, A3, A4 and M4 carbine series and M249SAW machine gun, and can effectively guide the distance of 875 yards. When used in M249 machine gun, every four M855 bullets are matched with one M856 tracer bullet. It is worth noting that M856 tracer bullet can only be fired by M16A1 rifle in an emergency, and its effective distance is less than 9m. The reason is that the rifling distance of M16A1 is 1:12 instead of 1:7 like M16A2, so it is easy to cause M856 warhead to roll and sway after leaving the muzzle, and the trajectory will become extremely unstable. The troops can use the lighter M196 tracer bullet (weighing 55g) to effectively indicate the distance of 5 yards. [2] Edit this paragraph Japan provokes. In early January 213, Japan will shoot the so-called tracer warning shots at the ships of the sea surveillance in Chinese mainland, including the aircraft of the sea surveillance, which may further worsen, intensify and escalate the situation on the Diaoyu Islands. Japan's new Prime Minister Shinzo Abe felt that Chinese mainland's patrol in the direction of the Diaoyu Islands was indeed normalized. The captains of several sea surveillance ships sent by Chinese mainland stayed in the waters of the Diaoyu Islands all night with tracer bullets to defend their rights, which put great pressure on Japan. In 213, Japan sent the so-called most advanced reconnaissance plane P3C for repeated reconnaissance, warning and tracking. P3C, a Japanese plane, has reached two or three times a day over the Diaoyu Islands. The so-called tracer bullet, as can be seen from the picture, is the bullet fired by Japan on the plane with a light source. Usually, when hanging the bullet, it is fired in front of the warhead with a chemical light trace and forms a series of launch trajectories. In the past, it was mainly used to show the trajectory, or to indicate the relevant flight route, and to show its existence and send out a "warning" in the region. Although it has no attack ability of live ammunition, it is obviously a blatant provocation. According to People's Daily Online, Peng Guangqian, a famous military commentator in China and Major General of the People's Liberation Army, said on the 14th that tracer bullets are live ammunition, but only live ammunition that will glow. The charge of some tracer bullets may be slightly reduced, and the killing rate is slightly affected. Playing tracer bullets is a kind of provocation, that is, "firing the first shot" and actual combat. If Japan dares to play tracer bullets, it means that it has fired the first shot, so we should fight back rudely, and we can't let him shoot the second shot. [3] US Assistant Deputy Secretary of State Campbell and Assistant Deputy Secretary of Defense Libert, who arrived in Tokyo on 16th, will hold talks with Japanese Foreign Minister and Defense Minister to exchange views on how to deal with the Diaoyu Islands issue. The United States is worried that if the Japanese Self-Defense Forces take the lead in shooting Japanese planes, it will cause China's counterattack, and an armed conflict is likely to occur between China and China. Japanese Foreign Minister kishida fumio will visit Washington on the 18th and hold the first meeting with US Secretary of State Hillary Clinton. It is reported that Hillary Clinton will ask the Japanese government to keep calm on the Diaoyu Islands issue in person to prevent the situation from escalating, and at the same time, she will ask Abe's cabinet to start negotiations with China on resolving the Diaoyu Islands issue and improving the relations between the two countries. On January 9, Japan's Sankei Shimbun reported that after taking office, Japanese Prime Minister Shinzo Abe proposed to strengthen vigilance against Chinese sea surveillance vessels and aircraft cruising the Diaoyu Islands. In this police record, it is included that once the China plane enters the Diaoyu Islands airspace, the Japanese side will use tracer bullets for warning shooting through the ships of the Maritime Self-Defense Force if the radio warning still fails. Japanese Defense Minister Onodera Satoshi indirectly indicated at a press conference on the 15th that if a China plane enters the airspace of the Diaoyu Islands, it will take the international practice to carry out "warning shooting". Edit the operational role of tracer bullets in this paragraph-tracer bullets-bullets with tracer at the tail of the warhead, which can emit light to show the trajectory during flight, and the head of the warhead is painted with green marks. Mainly used for test firing and indicating targets. This type of warhead has a cavity at the end and contains flammable chemicals. When emitted, these substances will burn, emitting colored light and smoke, which looks like a light beam pointing at the target to the naked eye. It is usually used on machine guns, and a tracer bullet is installed every four to five rounds, which makes it easier for the shooter to identify the direction of shooting, especially at night. Because of the danger of fire, most shooting ranges prohibit the use of such bullets. Tracer bullets usually use the red bullet tip as the identification mark, which is used for trajectory observation, arson effect or signaling. When shooting, the gunpowder gas in the chamber punches a hole in the gasket, igniting the igniter, which in turn ignites the propellant and finally ignites the tracer. After the bullet shoots out of the muzzle for a certain distance, the gasket is washed off by the propellant gas, and the bullet begins to trail light. Tracer bombs and conventional ammunition are staggered on the ammunition belt. When launched, the phosphorus in the tracer ignited, leaving a fireworks-like trail between the gun and the place where they hit. If the tracer bullet hits the target, so will the conventional bullet.
