"You guys come first, save yourself and say that I violated the operating regulations, if you can calibrate this sighting device, then I will lose." Qin Zhenhua said: "These apprentices, they just lack discipline, there is no way, Master Liu is not here, I will beat them and let them know that the sky is high and the earth is thick." ”

Qin Zhenhua put on the face of a master, just like Master Liu's virtue a few days ago.

The old man smiled: "Okay, in our army and in the factory, we have to have competitions, if we don't do competitions, then we can't innovate, we can only stand still, and I will be a referee for you." ”

Liu Dajun was dumbfounded.

Huang Chuanchuan was dumbfounded.

The sight of the tank is the most sophisticated thing in it, and they have been learning from Liu Jianzhi for many months, but they have not learned how to install it at all!

However, just now, they were shouting that Qin Zhenhua had no ability, and if he wanted to compare whose skills were greater, he would replace Liu Jianzhi, and as a result, people gave such a question.

If you say no, then you are clearly admitting defeat, which is absolutely not good, if you do, they don't know how to install that thing, how to debug, let alone know!

Liu Jianzhi told him not to touch the sights, moved a bolt, twisted half a circle, and the cannon was not allowed! If you want to debug, that's a lot of trouble.

Of course, they are too lazy to worry about this kind of trouble, who would have thought that they would really encounter it now, and it is not a rut.

"Huang Chuanchuan, are you okay?" Liu Dajun asked Huang Chuanchuan in a low voice, among these people, Huang Chuanchuan is the most clever one.

Huang Chuanchuan shook his head.

He had seen Liu Jianzhi operate, he was holding the instrument at that time, tossing for a long time, and then, he had to go out to test the cannon, try it once, adjust it once, sometimes, he had to try it four or five times, those cannonballs, I heard that they were expensive, so it was impossible for Liu Jianzhi to let them get started.

Not alone!

Huang Chuanchuan's eyes rolled twice, and then a ghost idea came up.

"Qin Zhenhua, don't fool people, you let us install it first, what about you? You clearly don't know how to install, you can't debug, and you want to learn from us! Huang Chuanchuan said: "You have the ability, you should install the sights of this tank and debug it!" ”

"So, you won't?" Qin Zhenhua turned his head to the old man again and said, "Uncle, you have to administer justice to us, they are already admitting defeat." ”

"Who's your uncle?" Liu Dajun was dissatisfied on the side: "Don't set it closely, you really have the ability, you can install it." ”

"Uncle, did I do it?" Qin Zhenhua continued to say to the old man, and the old man nodded.

"You use your watch, time it for me." Qin Zhenhua said: "Look at how long it takes me." ”

Hearing Qin Zhenhua's words, the masters on the side couldn't help but be surprised, what did Qin Zhenhua want to do? Record-breaking? Look at the time?

The masters calibrate the guns, and it often takes half a day, or even a day, Qin Zhenhua means that it can be completed in three or five minutes, don't be funny!

However, Qin Zhenhua has never been a person who plays cards according to the convention, in the past few days, Qin Zhenhua's performance is unbelievable, this time, maybe he can really make a name.

The teachers have a headache with the school cannon, what does Qin Zhenhua plan to do? What is the identity of this old man?

Li Changjiang was closest to the old man, turned his head to look at the old man's watch, and when he saw a sign on it, his eyes immediately widened.

Wanguo brand, a kind of watch, can wear such a watch, at least the commander of the army!

No wonder Qin Zhenhua was so affectionate just now, an uncle, he still looks at people!

The sighting device of the tank, which is an optical device, if you look at it from the position of the gun commander inside, you can see a circular field of view, which has a reticle that shows different scales, and before there is a computer fire control system, as a gunner, you must be familiar with the operation of this thing.

Different sights, the reticle is displayed differently, the common one in the West has a crosshair, and the target can be fired by pressing it to the crosshair, which is of course the most superficial understanding, if there is no professional knowledge to carry out various calculations, it will fly 100%.

The sight of the 59 tank is the TSH2-22 sight inherited from the T-54 series of tanks, and the number displayed inside the reticle is quite large, and there are four rows vertically, which are used for ranging, elevation, calculation of advance, etc.

The gunner needs to be able to use it, and does not need to know its principle, in the tank factory, to build a tank, of course, you have to understand the principle, this thing, in fact, is more than one meter long, is a device parallel to the axis of the tank gun, after all, the tank gun belongs to direct shooting, so, the school gun is actually calibration, so that the sight and the gun are really coaxial, so that the cross center of the sight is actually the impact point of the shell, which completes the calibration.

Now, Qin Zhenhua needs to do two things, installation and calibration.

He carried the black irregular long sights, went to the turret, and then skillfully drilled in, from the inside to the outside, because it had been dismantled once, so the current installation is also familiar with the road, skillfully screwing a few screws to fix it.

Installing sights can also reflect the proficiency of technology, especially since he is still a person, now, the old man saw Qin Zhenhua's nimble hands and feet, and kept nodding, yes, he is a good seedling!

"Hmph, don't look at him to install it so quickly, the most important thing is to adjust!" Huang Chuanchuan said on the side: "Adjusting the sight, it's not easy, our Master Liu, we have to toss repeatedly for a long time!" ”

"Erzhuzi, bring me the hand-held searchlight in the workshop!" Qin Zhenhua shouted.

What, hand-held searchlights? What does he want to do? In the standard operation of the school gun, there is no mention of using a searchlight!

Ordinary searchlights, which are very large in size and are mainly used for air defense, are generally placed in antiaircraft artillery units, and the searchlights cover the enemy planes, and the antiaircraft artillery can knock down the enemy planes.

However, there are times when special pipe repairs are needed in the factory, etc., so they will go with a small searchlight in hand, which is also wired.

Wang Erzhu heard Qin Zhenhua's greeting, and immediately ran over to get it, everyone was staring at each other, watching Qin Zhenhua take the searchlight in his hand, and then opened the gun door and stuffed it in.

At the muzzle of the gun, a bright light came out, and if you looked at the barrel, you might be blind.

Five hundred meters away, the gate of the workshop was in the shade of a big tree, and the light of the muzzle of the cannon shone on the gate, which could be seen clearly.

"He, he's the way he was a school gun in World War II, right?"
