"Green mountains and clear waters, deserts are bounded by the sky, hills are densely covered with vast plains. In the land of more than 4 million square kilometers, we have many terrain, many climates, and many humanities. We must adapt to these differences, integrate into these differences, have the ability to perform diversified tasks, and have the courage to accept any challenges."

Although Lin Xuewen has a name for Wen Lu, he is not a sour literary man. He is wearing a jungle camouflage uniform and paints "ugly" oil paint, and he dresses up like a jungle soul. Of course, the sniper step in his hand is the minion that is so cute to the evil spirit.

"Many times, many students have been trained in this special school. They are like you now. You who have never been hit. From joining the army to now, I have always felt that I am the best in the world. I have been trying to hit the crowd wherever I am, but I just can't tell who is higher and lower."

Lin Xuewen, like before, will give them a special class when new students enter school. "There is a student in the second period who was the number one sniper of their division before coming, including multi-terrain shooting, high-level dive angle shooting, fast gun-setting without correction sniper, no-reliance shooting, fast shooting, risk shooting, small target shooting, shaking target shooting, identification and judgment shooting, sniper duo-team shooting, etc. From 30 meters to 830 meters, this kid really wants to hit your eyes and never hit your nose. It doesn't matter whether he believes it or not, see the rock at the foot of the mountain?" Lin Xuewen pointed to a rock near the stream not far from the foot of the mountain. Those who came to receive training were all snipers, so naturally they could see the stone as big as ten cubic meters.

"When he came, he erected a 12.7mm machine gun heavy bullet shell on the stone. Just where you were standing, he used a 21 sniper to punch the shell against each other." Lin Xuewen said, and many students began to mutter quietly. The straight-line distance from where they stood to the rock was about 150 meters. "Later, after he finished the graduation assessment, there was a bullet left. Everyone asked him to perform the performance. There was a good start and a good ending. So we got a bullet for him that place and asked him to use the last bullet to complete the performance before leaving. Unfortunately, the shell was not 12.7mm at that time, but 7.62 for our sniper rifle."

"What's the result?"

"What else can it be done? Will students who graduate from our school have a big start and a bad start?"

After Lin Xuewen smiled, he glanced at the group of rookies. This time, he did private work for the Third Army. The recruitment was no longer the elites selected by each division before. The team in this period had as many as 120 people. If the commander of the Third Army Muda had not asked Lin Xuewen to help, Lin Xuewen would have returned to the Army Academy long ago. The school would have been handed over to other instructors. He had to go back to meet the commander-in-chief. It is said that he would have the life to lead the team. But before leaving, he would have to help the Third Army. It would be impossible to get in the way if he went back for a month late.

"By the way, unfortunately, from then on, this project has become a special assessment project. If you can complete this assessment, we will give you a reward for his excellent performance. Of course, the medal is the shell he pierced through. I hope everyone will take away a 7.62mm when they leave."

Lin Xuewen immediately became dumbfounded when he saw the students. After a smile, he said, "Nonsense is the first sentence of interpersonal relationships. Today I have enough time to talk nonsense with you. Let's get to the point. Everyone has it, sit down!" After a command, all the 120 students sat on the ground. Lin Xuewen was about to start the 30th class before he left.

"Bullets, commonly known as gun bullets, are composed of cartridges, bottom fire, fire medicine and warheads. When fired, the striker hits the bottom fire, so that the gas produced by the fire medicine burns out the warheads. People who have been soldiers for many years are very accustomed to golden bullets, but these bullets are no longer produced. Green bullets have replaced them, and many special colors of bullets have emerged, red, black, and white? Why?"

"There are more types of bullet bullet bullets because of different paths. In order to facilitate identification in battle, the arsenal paints different colors on the warhead to distinguish. The warhead is not painted or silver, and is an ordinary bullet used to kill the enemy's targets. It is a copper sleeve wrapped with steel or lead core. The green warhead is a tracer bullet. The front end of the warhead is a tracer tube in the middle of the lead core. The tube is filled with tracer agent and has a fixed ring to prevent it from leaking. Combustible materials, oxides and adhesives form tracer agents. So once it is launched, the warhead drags bright light on the night flight, showing its ballistics to indicate the target to correct the shooting."

"The bullet is painted in red as incendiary bomb. It is equipped with a burning agent at the front, a steel core in the middle, and a tracer at the back, which is used to ignite flammable and explosive substances in the area, such as the enemy's ammunition depot, fuel depot, vehicle fuel tank, etc. The black-painted incendiary bomb is the armored incendiary bomb. The steel core is different from the former, but a quenched high-carbon steel. The core is also covered with a lead sleeve. The combustion agent is installed at the rear end of the projectile, which is mainly used to shoot the enemy's fuel tank or have armored targets."

"There is also a kind of thing called armor-piercing tracer bullet, which is painted red in the bullet head and purple in the top. We don't often use this kind of thing. It gathers several bullet functions mentioned just now. It can not only indicate ballistics but also arson. It is suitable for large-caliber machine guns to use it to shoot air and long-range targets. Of course, there is also a kind of instant bomb that we don't often use or do not use, which is an instant bomb. The middle of the warhead is equipped with explosives, and there is a bullet cap at the front of the explosive, which penetrates the tube and the tube, and the tracer tube at the back. It is used by large-caliber machine guns to shoot air. When the warhead hits the target, it penetrates the tube and the tube to detonate the explosives. If you want to take a bite of that thing, the consequences will be serious."

Lin Xuewen said here, frowned and said, "Actually, we will probably use this instant bomb. If this guy gives someone a shuttle, it will be very powerful. But it is more vicious than vicious, there is a kind of bullet called a short bullet. This is a general term for expanding warheads. The expansion process is also called mushroom transformation. The warhead after expansion is like a mushroom. The head is big and small. Hunters naturally like this bullet. The prey dies quickly, and the warhead will not break like a Dam bullet, but it is an evil bullet no matter what, and is restricted by the Hague Convention. Okay, let's introduce it to you today. In the future, we have to learn how to use these bullets. Everyone has it and stand up!"

The mountain wind is fluttering, the grass is fat and green. The Army Sniper Jungle Special Training School in the deep mountains has spent several spring and autumn alternating in such a beautiful nature, welcomed a group of arrogant rookies and sent away a group of calm masters. Although it is a jungle special training school, its professional courses are no longer limited to jungle. The reason why Lin Xuewen talks so much today is because the targets the snipers are no longer single. The People's Army has implemented the idea of ​​"spike and shield". From military equipment to strategy and tactics, the Army began to pay attention to armor, which is obviously in the research of "shield". Snipers are breakthroughs in "spikes". Professional special ammunition and stronger and better guns will enter the snipers' equipment bar because they are always the sharpest and sharpest spears.

"The army needs a lot of ammunition, but in fact, there are guns, shells, grenades, grenades, etc. The most consumed is guns, bullets, and the three armies all need to be equipped with guns, rifles, light and heavy machine guns, and sniper rifles. If the army is in use, they will consume ammunition. Especially now that the scale of the army has expanded, the consumption of guns and bullets is even greater, and it is a headache to think of it!"

After inspecting Kunming Machinery Factory, Zhang Yu saw batches of precision boring machines. After milling machines, he was in a good mood. However, after arriving at Kunming Ammunition Factory, he saw cars coming and going to transport raw materials and transporting ammunition. Quality-oriented military construction was destined to be professional, scientific and long-term training of the army. The result is that the biggest consumption of the army is ammunition and grain. Both of these consumptions are enough for people to harbor.

"My mother, the military expenditure is increasing year by year, and this year is very much. We have been stingy for most of our lives to accumulate a little family background. With more people and more military branches, even if it is routine training, the guns will be worth tens of thousands of taels. I hope these soldiers can understand Lao Zhang's efforts. When shooting guns and tossing targets, they should be more at ease. Don't pull the trigger, and you won't know what your surname is when you pull the rope!"

After muttering, Zhang Yu opened the car door and got out of the car. After sending Yu Ran to the Army Academy for further study, the only days of traveling around Kunming were left. Because the people who traveled around were military factories, they didn't even bring the guards. However, they didn't expect to come to the "sad" place. Since they came, they had to go in and take a look.

"In the era of smokeless gunpowder, this nitroscopic cotton was very in short supply!" After inspection, I walked into the factory and saw special chemical special vehicles one by one in the special parking lot of the factory. Zhang Yu's eyelids were trembling. The heavy industry in Kunming has developed vividly and the pharmaceutical industry is also very famous. The largest China Minsheng Pharmaceutical Group in the autonomous region is in the province. Of course, the second largest ammunition manufacturer in the southwest is also here.

Pistols use porous fast-burning single-base drugs, and the rifle has a single-hole particle single-base drugs that are lightened and passivated on the surface. The reason why firearms have strong lethality is entirely because their bullets are huge kinetic energy, and the chemicals that give them great destructive power are the chemicals that do work for them. However, bullets do not only require their destructive power, but also require detailed requirements for their size and accuracy. Then bullets must have a complete structure and appearance. Therefore, in the age of hot weapons, there are people who can make guns without a complete set of serialized processing equipment and corresponding process levels. Where can bullets be made?

"Commander-in-Chief, why are you here?"

"What's wrong? Why can't I come? Don't you welcome it?"

Zhang Yu saw a satisfactory scene along the way, and everyone was busy. However, when he arrived at the factory manager's office, he saw a guy who really looked left and right with two bullets, and then he woke up with a cough.

"I'm looking at the bullets produced in our factory? Not long ago, I asked the senior technicians in the factory to see if the bullet is qualified at a glance. However, this old eye has been looking at it for a long time, but it still can't tell who is not qualified at all of these two bullets?" The factory director said, handing Zhang Yu the two nearly identical 7.62mm ordinary bullets in his hand.

"Do you think you are a senior technician? If you don't manage production well as a factory manager, why are you competing with these treasures?" After Zhang Yu cursed, he picked up the bullets and took a look. He usually goes to the underground shooting range of the armed forces to practice guns every day. There are tens of thousands of bullets he has consumed over the years, but he really can't tell who is qualified for these two bullets.

"By the way, Commander. The factory's production line has been upgraded for some time. Why don't we go and have a look?" The factory director didn't dare to say that Zhang Yu couldn't tell who was qualified. He quickly changed the topic. After getting the approval, the two of them dropped the bullet and rushed to the factory area. "Commander, this extension processing technology is very useful,"

The extension processing mentioned by the factory manager means the production of parts of different shapes and wall thicknesses, and only by changing the shape and size of the mold. When producing a bullet shell, it means that the diameter of the steel ball made of copper-clad steel strip or round steel is reduced and the wall thickness is reduced. In the past, the People's Army Arsenal used a single-mode extension process, and the deformation amount of one processing is very small. After multi-mode stamping, a relatively large deformation amount can be obtained within one stroke.

Moreover, since the production of bullets has extremely high requirements for accuracy and consistency, the size of parts is basically guaranteed by molds. Due to the large batch size, if there is a deviation, it will cause waste. Therefore, there are high requirements for the manufacturing and installation of molds. Every link must be strictly checked. Once unqualified products are found, they should be removed immediately and the machine tool should be adjusted immediately. Therefore, the excellent technical workers in military factories are outstanding.

"A bullet shell production, cutting and flushing, appearance selection, annealing, pickling, extension, thrusting, extrusion and flaring. The whole process is safe, so all use assembly line operations. There is our annealing treatment workshop. With their existence, the cold hardening of the blank due to severe deformation during processing can be eliminated. The workshop downward is a pickling bathroom. This link is indispensable for removing the scale on the surface of the blank during annealing."

Punching is a special stamping process in the production of bullet shells, which is to punch out the arc size of the tip of the projectile. Since there is a certain margin left at the tail of the bullet shell after processing, it is necessary to cut it with a cutter or remove the excess with an extrusion die. The latter can also use the oblique surface on the punch to flar the tail of the bullet shell, which facilitates the assembly of the spring core in the future, and improves the consistency of production efficiency and product size.

"Every day, our eyelids keep jumping until midnight. The reason for jumping is that every day, the three navy, army, especially the army, from sunrise to sunset, how many bullets will be knocked out in this day..."

"I said, Lao Chang, you are so sad, I haven't said anything yet, you are worried." Zhang Yu glared at Director Chang's eyes, and then walked around the factory to take a look. "I think you wish the army would arrange shooting training every day, and the benefits of the many ammunition factories rose sharply. But I can say that in front of me, you should produce less bullets that are not qualified. I don't want the bullets in my hand to be a piece of waste. Who dares to shoot that thing?"

When Zhang Yu arrived here, he sighed that military expenditure increased year by year. In fact, the increase in military expenditure of the People's Army was not large. In 22 years, the military expenditure budget increased significantly because of the emergence of new military branches. The navy and the air force were in the growth stage and required a large amount of military expenses for growth. Conventional training, equipment purchase, hardware construction, etc. were all piled up in one piece of RMB. To be honest, the bullet consumption was very large, but its production cost was not very good, but the annual consumption was too much, which was expensive to calculate.

In particular, the army attaches great importance to the shooting ability of soldiers. The most mortal thing is not that the army snipers reach the squad level, but that each soldier is equipped with a pistol, nine divisions of the army, one fast rebel brigade, and the troops with more than 100,000 people are equipped with a pistol. The shortage of people is no longer ordinary rifle bullets, and the consumption of pistol bullets is also "unbeatable". Even if the People's Army upgrades and transforms the production technology of subordinate military factories and adjusts the types of bullets, a bullet does not cost much, but after the number is too high, the result of multiplication between the two will obviously create a terrifying number, so if you do not have enough strength, you cannot afford to support a high-quality army.
