Chen Er was stunned when he heard this, no wonder these seven people were so well-behaved, it turned out that they were waiting for themselves here, and they hadn't conducted a basic assessment for them, but they had taken the test as a teacher first. ≌However, Chen Er is not the slightest bit angry, at least it proves that these people are not so blind, they still have their own opinions, and if they want to achieve certain achievements in the military industry, this is also necessary.

Looking at the smiles on the faces of the seven people, Chen Er seemed to see the victorious look in their hearts. But in Chen Er's opinion, these are really pediatrics, if he can't even do this, then this big military industrial system is too wasteful. With a slight use of his brain, all the numbers about the Japanese-made Type 92 infantry guns in the large military industrial system appeared, and Chen Er also turned around and walked towards the courtyard.

Since he wants to talk about it, Chen Er wants to talk about it specifically, and he can be regarded as taking advantage of this opportunity to establish his prestige. As long as I can suppress them this time, all the work from now on will be much easier. Seeing that Chen Er had already left the house, the seven of them naturally walked quickly to the courtyard, and they were all full of expectations for Chen Er's next words. Chen Er's level also depends on his answer.

Chen Er slowly walked to the 92 infantry cannon at this time, looked at the appearance of the whole cannon and said with some pity: "This look is a defective product." It may have been destroyed in the war. Because Chen Er saw that many of the key parts of this 92 infantry gun were missing, although the whole was still complete. But it has already lost any combat effectiveness, and it is just a pile of scrap metal here.

The fat man thought for a while and asked, "Director Chen, you haven't introduced this cannon to us specifically, we don't care if it can be used now, we just want to know about its various numbers." Seeing these seven college students who couldn't hold on to the Yellow River's heart and immortality, Chen Er had no choice but to start his performance time. I only heard him open his mouth and say: "This cannon is a Japanese Type 92 infantry gun, let's first talk about the performance number of this gun, Type 92 infantry gun caliber: 7o mm, barrel length: 8.79 times the caliber." Total gun weight: O.212 tons, length: 2.745 meters, total gun height: O.62 meters, high and low firing angles from -1o degrees to +75 degrees, range firing range: 45 degrees left and right. The Type 92 infantry gun uses a 7o mm high-explosive shell, the total weight of the shell is 3.8 kg, the initial range of the shell can reach 198 m / s, the maximum range of the shell is 2788 meters, and the minimum range is 1oo meters. These are just some of the basic numbers. Let's talk about the rest.

"The Type 92 infantry gun was an ideal infantry battalion support weapon in the thirties. This is especially true for countries with extremely low mechanization levels. Plus, it's perfect for use on complex terrain. For example, for infantry battalion support in mountain warfare, it is very handy. And it has a wide range of tasks. It can cover almost all types of fire support required by an infantry battalion. Coupled with the simple structure, it is not only convenient for wartime production, but also easy to use and maintain. Therefore, our troops are still equipped with a lot of Type 92 infantry guns captured from the War of Resistance Against Japan. ”

"The total weight of the Type 92 infantry gun was only O.212 tons. In the case of 75 mm class artillery. It's really light. Therefore, the requirements on transportation are low. In the absence of a vehicle, untrained animal power or manpower can be towed forward. In addition to which it can be broken down for transportation. The requirements for road conditions in the war zone were almost reduced to a minimum. It can be said that the Type 92 infantry gun is an infantry run that can truly accompany the infantry battalion in combat unconditionally. ”

Probably after waiting for the seven people to react, Chen Er continued: "Moreover, the Type 92 infantry gun is a very short artillery, its total height is only 62 centimeters, and this is still the height of the shield. If the shield is removed, the full height will drop to about 5o centimeters, which is about the same height as a heavy machine gun. This means that the Type 92 infantry gun can be easily concealed, which is a very useful advantage for infantry guns that need to fight in the line of fire. Taking advantage of this advantage, the Type 92 infantry gun can be deployed covertly at a very close distance from the enemy's target, fully wielding the accuracy, suddenness and ferocity of firepower, and giving the infantry the support it needs at the first time. ”

"Moreover, the firing range of the Type 92 infantry gun is very open, with a horizontal firing range of 9o degrees, and a high and low firing angle of nearly 9o degrees. This is mainly due to the small size and light weight of the Type 92 infantry gun, coupled with the low center of gravity, so it can withstand a relatively large range of firing angle adjustment. Flexibly applying the angle of fire, especially the elevation angle that is said to be more than 8o degrees, the Type 92 infantry gun can shoot almost one qiē type target. Flat fire can be used as a cannon, which is enough to deal with civil fortifications and general masonry fortifications, and although the shells are initially lower, they are still powerful enough to hit unprotected vehicles and armored vehicles. ”

"Curved shooting can be used as a howitzer, and it can be used as a mortar when firing at a large elevation angle, and the maximum angle of fire of many known mortars is only 85 degrees, because the Type 92 infantry gun is a howitzer, and the trajectory is much more stable than that of mortars, so the accuracy is much better than mortars of the same caliber level. At the same time, with the help of high firing angles, when fighting in mountainous areas, the Type 92 infantry guns can be conveniently deployed on the anti-slope position, which can not only provide timely support firepower for their own troops on the ridge line or frontal position, but also conceal themselves well. ”

"And the most worthy of the attention of those of us military workers is that this is a weapon that was researched more than 20 years ago, and it can still be equipped by the troops, and it is conceivable that it still has many advantages that are difficult to replace by other infantry artillery. Of course, these are just some of my personal opinions, if you have any ideas, you can say them, and it would be great if we could brainstorm them. After all, we will be comrades-in-arms in the future. ”

As soon as Chen Er's words were finished, he looked at the seven people again, and they all looked like defeated roosters. I don't know what I'm thinking when I keep my head down. This teacher's assessment can be regarded as a smooth pass, Chen Er coughed and said, "Do you still have any questions?" Even though I can bring it up, I promise that I will answer you without reservation as long as it is within my ability. ”

Chen Er introduced this cannon to this Cheng dù, and even fools could see that Chen Er was the kind of person with real skills. This question was something they came up with on the spot, and they didn't give Chen Er any time to prepare at all. And Chen didn't even have a book on the second-hand, so he told them about it, and the seven people completely hit the south wall this time, and it was not okay if they didn't give up, and they really responded to that sentence, there are people outside the world.

At this time, Ding Jun suddenly spoke: "Director Chen." Can I ask a question? As soon as Ding Jun's words came out, the other six people all looked at him with stupid expressions, when he wanted to make things difficult for Chen Er, Ding Jun was the most opposed, and what questions did he have to ask at this time.

Chen Er, as their temporary teacher now, naturally did not refuse to come, he nodded and said: "Your name is Ding Jun, you say, as long as I can answer you, I promise that I will definitely not hide it." Ding Jun hesitated for a moment but then stubbornly said, "Director Chen, I just want to know how old you are." How long have you been in the military industry? After listening to Ding Jun's question, the other six people were also relieved.

They were afraid that Ding Jun would ask about the cannon next to him again, which was already a shameful thing, if Ding Jun really asked like that, they would probably be completely embarrassed. Chen Er also didn't expect Ding Jun to ask such an inexplicable question. But after thinking about it carefully, it seems that there is a little bit of a relationship, and I just made a guarantee. It seems that if you don't answer, you will ruin your own image.

Anyway, there's nothing that can't be said about this, and it is said that a woman's age is a secret. What are you afraid of? Thinking of this, Chen Er smiled and said, "I don't know how old you are, anyway, I should be twenty-four years old this year." As for the profession of military industry. It's probably been less than two years, and it's pretty fast to think about it, from a college student who doesn't know anything to get here. ”

Hearing Chen Er's words, the seven of them felt even more embarrassed, the oldest of them was already twenty-five years old, and the youngest was twenty-three years old. Compared with Chen Eryi, the aura above their heads seemed to be half blown away by the strong wind all at once. Almost the same age, Chen Er can come here to be the director of this research workshop, but they are still just a small apprentice, this is the obvious gap.

It is said that once a person has a goal, he will have infinite motivation to move forward, and Chen Er at this time has suddenly become the goal in their hearts. Thinking about all Chen Er's actions since he arrived here, the seven of them felt bursts of self-blame in their hearts. They are completely crossing the belly of a gentleman with the heart of a villain, Chen Er's previous modesty was regarded by them as acting, Chen Er's previous politeness was seen by them as hypocrisy, and the seven people are really repentant to death now.

Chen Er didn't know the slightest thought in their hearts, and he was also afraid that the seven people would sink because of today's blow at this time, so after thinking about it, he said encouragingly: "Actually, what I just said are just some descriptions in books, as long as you seriously want to study, these are not problems." I remember someone saying that youth is capital. We are all people with considerable capital now, if we don't work hard for the country at this time, then we will definitely regret it very much when we are old, and we may not be able to face our children and grandchildren. ”

"I don't know if what I'm saying is right, maybe if you like to chat with the elderly, you will have more insight, after all, their experience is far greater than ours. I won't talk nonsense, let's continue the lecture. Saying that, Chen Er went into the house and took out the small blackboard, this ghostly hot weather, if the seven people stayed in that room, they would have to die of suffocation if they didn't die of heat, how good the yard was.

After the previous incident, the seven people have changed their inner thoughts, the purpose of their coming here is to serve the motherland, and now since they can achieve such a goal by following Chen Er, why don't they do it. Chen Er stood in front and said, the seven of them all listened attentively, for fear of missing anything, and would write something in the notebook from time to time. The one-hour class was over quickly, and the seven of them all had a feeling of unfinished, and of course Chen Er, the teacher, also felt that his throat was smoking.

On such a hot day, speaking for an hour in a row can be regarded as a challenge for Chen Er. This time it was finally over, he quickly drank some water, and rested for a few minutes before he felt much more comfortable. Looking at the seven people who were still discussing there, he said: "I'll go back first, you can digest what you heard today, and I believe that with the continuous study in the future, your progress will be greater and greater." ”

In this way, Chen Er walked out of the small courtyard in the eyes of the seven people who got up and watched, Chen Er naturally felt good, and this was the end of this first class. (To be continued!)
