"Do any of you know the exact composition of the bullet?"

Yang Chen asked after looking around.

"Teacher, I know this."

Yang Chen nodded at the student who was sitting at the third table of the second group.

The cadet stood up and said, "The bullet consists of a warhead and a cartridge case!" ”

"That's not right."

Yang Chen shook his head.

Everyone was confused, because in their cognition, the bullet is not composed of a warhead and a cartridge case?

Yang Chen used his right index finger to point to the bullet pinched between the thumb and index finger of his left hand and said: "The general bullet is composed of four parts: the bullet head, the cartridge case, the propellant and the primer.

In which the warhead is used to strike the target.

The cartridge casing, also known as the cartridge, is used to connect the warhead to the protective propellant, as well as to seal the propellant gas.

The function of the propellant is to produce gas through combustion, so that the air pressure inside the shell expands rapidly, thereby pushing the warhead to shoot out, and giving the warhead a high muzzle velocity.

A primer, also known as a fire cap or fuse, is used to fire and ignite a propellant. ”

"Then the principle of bullet shooting is that the bolt hits the primer of the bullet, ignites the propellant inside the cartridge case, makes it produce gas, and quickly increases the internal air pressure, thereby pushing the warhead to shoot.

The bullet shot from the cartridge case, through the rifling in the barrel, causes the bullet to rotate, which can greatly improve the stability of the bullet after it is ejected and increase the lethality! ”

Everyone suddenly realized and quickly used their notebooks to write down this knowledge.

The student who had just stood up was also instructed by the teacher Yang Chen's eyes and sat down again.

"Now that you've learned about the structure of bullets, I'm sure you're desperate to know how to make bullets, right?"

Yang Chen asked himself and answered: "There are two ways to make bullets, original and reloaded. ”

"As the name suggests, the original is brand new, including the cartridge case, warhead, propellant and primer.

Then put it together, and it becomes a brand new bullet.

This assembly process is not too difficult, the difficulty is how to produce the warhead, especially the shell.

And it has to be accurate! ”

"Reloading is to collect complete usable shells from the battlefield, reload the propellant, and assemble the warhead and primer.

Comparatively speaking, the cost of reinstallation is much smaller. ”

……

The arsenal has not yet been built, and all kinds of machines and instruments have not been placed in the workshop.

The first day of the course is to teach everyone to be familiar with the composition of bullets, the principles of gunfire and so on.

At the same time, Yang Chen also took out bullets, grenades, grenades, and detailed drawings of various weapons and equipment.

In the end, Yang Chen threw out a bombshell, taking out the drawings of planes, tanks, and battleships and aircraft carriers.

The drawings are very detailed, down to the exact exact exact detail, including the screws.

It was an eye-opener to see the students; The admiration for Yang Chen, the group seat, has improved a lot.

One of the students asked with a shocked face: "Tuanza...... No, teacher!

With these drawings, can we produce tanks, airplanes, and even aircraft carriers? ”

"Of course!"

Yang Chen nodded heavily: "However, with the current industrial level of our Tiger Ben Regiment Arsenal, we can't make these things."

After all, there are a lot of equipment that we don't own, engineers or even workers don't have.

The required materials, etc., are also none.

However, with these drawings in my hands, it is only a matter of time before these things are produced! ”

Saying this, Yang Chen's sharp gaze swept across the classroom, and everyone straightened up, and their hearts were boiling.

"I believe you all know that if you want to make anything, even if you build a house, the first thing we have to do is to draw drawings, and the most important step is to draw drawings!

Therefore, it will not be long before the development and growth of our Tiger Regiment.

There will be tanks, there will be planes!

And you are the first engineers and pioneers of our Tiger Regimental Arsenal.

Once these things are made, you're credited with it!

Your name will also be remembered by the world and even written in the textbooks of future generations! ”

"Shhh ——”

Agitated! The blood is boiling again!

Celebrities through the ages, who doesn't want to?

"However, you need to understand that if you take a big step, it is easy to pull the egg; Meals should be eaten one bite at a time, and things should be brought one by one.

Right now, the most important thing my tiger regiment lacks are bullets, grenades, grenades and artillery shells.

So, the first thing you have to learn is to produce these things. ”

And all the people withdrew their minds.

"Attention! You are engineers, not ordinary workers! When the arsenal is completed, I will gather a large number of employees.

What you have to do is to overcome the problems of producing bullets, grenades, grenades and artillery shells, as well as advanced weapons behind them.

And teach the workers how to manufacture!

Do you understand your position? ”

"Understood!"

The crowd agreed.

They were originally born in the military, participated in real wars, and walked out of the sea of corpses and blood many times.

Naturally, there is a kind of resoluteness that others do not have!

……

For a few days, Yang Chen was teaching in the military school, that is, the training class.

The arsenal is also under construction under the supervision of Chief of Staff Wang Gui, who is working overtime.

And the training of the recruits, too, did not fall behind.

On this day, the Tiger Ben Regiment Headquarters.

The battalion commanders and high-ranking officers were all present to report to Yang Chen, the regimental seat, on the achievements and progress of the work in the past few days.

At this time, the battalion commanders were no longer satisfied with the status quo.

Liu Zheping, commander of the first battalion, took the lead in suggesting to Yang Chen: "Tuanzao, the northwest area of Huoshan County is mostly mountainous and has limited population resources.

If we want to recruit more recruits, we can only extend the scope of activities to Huoshan County!

Only close to the county seat is more densely populated! ”

"Then go!" Li Jiufu was an anxious person, and he said without thinking about it: "With our current strength, it is not easy to defeat the county seat?" ”

"It's not that simple!"

Yang Chen stood up, picked up his baton and came to the military map hanging behind him, and said: "After the fall of Lujiang, Shucheng, Lu'an and other places, there is a good chance that Huoshan County has fallen into the hands of the Japanese army!" ”

After a pause, Yang Chen said again: "Therefore, before you have accurate information, you must not act rashly!" ”

"Tuanzao, why don't I go to Huoshan County to reconnoiter and see the specific situation!" Xu Hailang, commander of the reconnaissance battalion, said.

Yang Chen pondered for a moment and said, "Your battalions now have their own defense areas and stations, the recruitment and training of recruits, and the assistance of the people to engage in production and self-help, these cannot be left behind.

Especially your reconnaissance battalion, which is now the strongest combat strength of my Tiger Battalion.

We must stay to ensure that in case, because our Tiger Ben Regiment has not been destroyed, the little devils will not give up.

Maybe sometime, I'll come back with a big army!

Therefore, in addition to guarding the base area, your reconnaissance battalion should also focus on the direction of Jinzhai County in the north.

If the Japanese attack, it is very likely to be killed from this direction.

In this way, I will personally take a few people to Huoshan County to conduct on-the-spot reconnaissance.

You stay and get on with the work at hand.

We can also expand the scope of recruitment to towns and villages outside the mountainous areas, and gradually expand the scope of our base areas.

Don't rush anything! If there's anything, you guys can discuss it on the radio! ”

"It's good!" After listening to this, everyone felt that Yang Chen's arrangement was reasonable, and nodded in agreement: "You have to be more careful when you go here." ”

"Don't worry, it's just a reconnaissance, it's a trivial matter." After Yang Chen finished speaking, he instructed them again.

This was the end of the discussion.
