"Have you never touched a cannon?" an instructor confirmed again.

Chen Shanhe replied: "Yes, instructor, I have never touched a cannon!"

The instructor confirmed again: "Then do you know the specific data of this gun?"

Chen Shanhe shook his head again: "I'm sorry, instructor, I don't know!"

The instructor sighed inwardly, but did not show it on his face, but he was already prepared for the answer.

"Next, let me talk about the specific data of this 94-type 75-caliber mountain gun.

This cannon was the best mountain cannon during the Japanese invasion of China.

Caliber of this gun: 75mm

Barrel length:1.560m

Cannon diameter: 20.8 times

Standard recoil distance: 0.86m

Track distance: 1.1m

Listed weight: 536 kg

Pitch angle:﹣10°~﹢45°

Horizontal shooting range: 20° to the left and right

Rate of fire: 10-20 rounds/minute

Muzzle velocity: about 350m/s~390m/s (varies depending on the type of ammunition)

Maximum range: 8.3 kilometers

These are the theoretical basic data of this gun. If you want to use this gun, you must first understand the basic data of this gun.

How much do you know about the shells of this gun?"

Chen Shanhe shook his head: "Are there many types of cannonballs?"

The instructor had no choice but to turn around and salute Xia Chang: "I need to apply for all types of ammunition for this gun!"

Xia Chang nodded: "Except for special shells, everything else can be approved!"

After that, I asked someone to make arrangements.

The instructor turned back with satisfaction.

Another instructor was already changing to the next topic: "Since you want to use this cannon, you must understand its structure.

Then, let’s start teaching you how to disassemble and assemble this gun. Just like after you join the army and get a firearm, what you need to learn is not how to shoot a gun, but how to quickly disassemble and assemble the gun.

If you want to use this cannon well, it is the same as if you want to use a gun well, you need to understand it first and be familiar with it, even if every part has its own special meaning!

So what I’m going to teach you next is how to dismantle the cannon!”

After saying that, we got started.

In fact, dismantling this cannon usually requires two or three people to cooperate with each other.

But one person can do it, it's just slower. After all, this cannon is very heavy.

The two instructors first demonstrated how to quickly disassemble and assemble the gun by cooperating with each other.

Then he demonstrated how to disassemble and install the cannon alone.

In fact, it's quite difficult if you don't understand it. After all, this is a cannon weighing just over 1,000 pounds.

However, it is not difficult if you understand the disassembly and assembly sequence.

Because after being disassembled, its heaviest component is only over 90 kilograms, and things weighing over 100 kilograms can be easily assembled with levers and tools.

Even without tools and just one person, the barrel weighing more than 100 kilograms can still be levered up.

Of course, generally speaking, there will not be only one person disassembling and assembling the artillery. If there is only one person, then why disassemble and assemble it?

I can't move it away, I can't carry it!

So this is just a training method, in fact, to let a person understand the order of assembly.

Moreover, the two instructors explained how to make it faster while disassembling and assembling it.

Then Chen Shanhe and one of the instructors were asked to work together to learn it. Some people said that listening to it 100 times is not as good as practicing it once.

If one time doesn't work, do it twice.

If two times doesn't work, do it 10 times or 8 times.

Chen Shanhe now has a very good memory, and what surprised the instructors is that he is also very strong.

No one needed to lift the 94kg gun barrel. I picked it up and installed it all by myself. It seemed very easy.

Then he started to disassemble and assemble it with great interest, which tortured the instructor so much that he quickly gave him another one to cooperate with, and then he sat aside to rest.

Chen Shanhe was practicing so much that he forgot that there were Yang Baiqian, Xia Chang and others next to him. Because of his concentration, he became proficient in the practice very quickly.

In fact, the instructor said that he has made rapid progress. In addition to his good memory, the most important thing is that his physical fitness is so good. It has been an hour since the beginning and he has not been out of breath.

If you are physically fit, you can practice it more often. If you practice it more often, no matter how stupid you are, you can become familiar with it.

So the instructors could only cooperate and dismantle and reassemble the artillery, disassemble and reinstall, and reinstall and disassemble.

Now Chen Shanhe can disassemble and assemble faster with any one instructor than with two instructors, which is outrageous.

"Okay, take a break, you have passed this subject!

After a short rest, we will move on to the next subject!"

Seeing someone carrying artillery shells in the distance, the two instructors quickly stopped the training.

They were really scared.

This person is such an animal. I haven't even seen a few drops of sweat left. Both of us are almost exhausted.

Xia Chang looked at Chen Shanhe, who was obviously not tired, and paid more attention to it.

After the shells were put down, two instructors opened the shell boxes.

"Now I will teach you how to understand all the ammunition of this 94-type 75-caliber mountain gun.

Of course there are some special shells, but they are not available here.

But it existed before. When the Japanese army first invaded China, they often used special artillery shells!"

Chen Shanhe understood what special artillery shells were, but didn't ask much.

An instructor opened the first box and took out a cannonball with both hands: "Introduction from the beginning, this is called a Type A grenade, and it weighs about 7 kilograms."

After putting it back, he picked up another artillery shell from the second box: "This is a Type B grenade. It weighs about 7.2 kilograms."

"Whether it's Type A or Type B grenades, their charges are picric acid and dinitrotoluene!"

"This is the Type 95 armor-piercing grenade. As the name suggests, this thing is used to deal with armored troops!"

"This is an armor-piercing grenade. It was effective against the bunker towers and armored troops at that time!"

"This is a Type II armored grenade..."

"This is the Type 94 grenade specially designed for this gun. The warhead is very heavy, 0.8 kilograms, and it is very powerful. After all, it contains TNT potent powder!"

"Except for a few special ammunition that have not been introduced, these two are the final artillery shells. This is the Type 90 smoke screen bomb, and this is the Type 90 illumination bomb!"

The instructor taught very carefully. Only by understanding the differences between these shells can you know how different ammunition should be used in different ways.

For example, anti-personnel grenades and armor-piercing projectiles designed to destroy bunkers or armored forces have different uses.

As well as the range of these ammunition, the range is different due to different shells.

The instructor taught very carefully, and Chen Shanhe also studied very carefully. Then the instructor slowly became shocked.

They found that no matter what they taught, the veteran comrade in front of them actually learned it as soon as it was taught and remembered it as soon as it was taught.

I don’t know whether he understands it or not. Anyway, he has remembered it. Whether he understands it or not is a matter later. At least he has remembered it.

Finally, I finished handing in the disassembly and assembly of the artillery structure and the understanding of the artillery shells.

The critical point has been reached.

That is this gun. When using what shells, how to calculate the range and impact point?

"Do you know what shooting Zhu Yuan is?"

Chen Shanhe has heard of it, but has not studied it in depth. Now that he has a teacher, he will start everything from scratch!

So he shook his head.

The instructor seemed to have expected it and handed over a few pieces of paper: "A series of parameters such as pitch angle, scale, and direction angle are called shooting parameters.

Generally speaking, shooting elements are divided into two types, one is direct aiming shooting elements, and the other is indirect aiming shooting elements.

Memorize these theoretical knowledge, and then ask us if you don’t understand anything!”

Suddenly, Xia Chang said: "Comrade veteran, take a rest!"

Then he said to Yang Baiqian: "You accompany Comrade Veteran to take a break, drink some water or something!"

Yang Baiqian was baffled. Chen Shanhe was very involved in practicing, and she was also very involved in watching.

However, she also understood that the person in front of her named Xia Chang would not ask her to take Chen Shanhe to drink water for no reason.
Chapter completed!
