The door of the courtyard house has been welded dead

"This is a spirit level. You need to make sure that the bubble is within this circle. After the first few rounds of firing, you need to pay attention to the position of the bubble. If the bubble moves to the rear of the vehicle, the hydraulic rod at the stop hoe must continue to press down to raise the rear of the vehicle. If the stop hoe reaches the bottom and cannot be pressed down any more, then retract the hydraulic rod at the front of the vehicle body~!"

While Li Feng was still discussing with Commander Yue about trying to equip a battalion first, the master craftsmen from the Red Star Factory were carefully teaching the old artillery squad leaders brought by Commander Yue.

Every detail, from which rod to which part of the hydraulic rod to the level, was taught to them step by step.

These details all concern the front and rear balance of the truck gun, and were obtained by the technicians of the Red Star Factory through repeated tests. Originally, they had to use a spirit level to measure, but later they simply installed this center bubble level.

"Keep the vehicle in a horizontal firing position so that the vehicle body is flat. The recoil after the cannon is fired will not overturn the vehicle~!"

Technician Kang Ming spread his palms flat to represent the car body, and while gesturing, he described the consequences of an uneven posture. The old squad leaders listened very carefully. Maybe their cultural level was not very high, but they knew more about artillery firing than the people from the Red Star Factory present.

"We know this. When digging the hoe, we also have to make sure the ground is flat. If it's not flat, the cannon won't fire accurately~!"

Although the spirit level of the truck gun is different from that used by artillerymen, the principle is the same. After the old squad leaders took turns looking at the spirit level fixed on the vehicle body, they all nodded with understanding.

"Can any of you repair the car?"

After Kang Ming finished speaking, Master Jia, who was lying under the car, poked his head out from under the car. After hearing the question, the nine old squad leaders looked at each other and almost shook their heads.

"I can repair a cannon with my eyes closed, and I know a little bit about repairing a car. But, this car is different from our Jiefang. It doesn't have that long nose~!"

One of the squad leaders squatted down and took a look at the chassis of the truck gun. It was quite different from the old Jiefang. After all, the old Jiefang had one drive shaft that went directly to the rear gear, while this car had more drive shafts and gears than the old Jiefang.

"This is the chassis of an off-road truck. The front row of wheels and the two rows of wheels at the back will all be driven by the gearbox. After firing the artillery, be sure to bend down and check it in time. Although this place has been reinforced and is not prone to problems, if there is oil leakage on the ground, it must be checked~!"

“And here…!”

Due to the tight time schedule and heavy workload, Master Jia did not instill too much complicated vehicle chassis knowledge, but simply explained the most important points in general.

If the cannon breaks down, the worst that can happen is that it can't fire shells. Cannons with purely mechanical structures are also the least likely to have problems. On the contrary, the complex chassis structure is the problem that is difficult to change for truck-based cannons.

To carry a cannon weighing several tons and shells, and to maintain normal driving in muddy ground, on steep slopes, and in complex road conditions, it is necessary to have an off-road truck chassis.

After nearly half a year, Master Jia gradually understood the chassis principles of this car, but this kind of experience cannot be directly instilled. It is something that can only be acquired after decades of car repair.

"Yes, Master Jia is right. Once there is oil on the ground, you must be careful. Whether it is lubricating oil, engine oil, or hydraulic oil, you must pay attention to it~!"

After listening to Master Jia's description, Technician Kang immediately added that this cannon took half a year to polish. To be honest, if Secretary Li was not in a hurry, he would rather continue polishing it for another half a year or a year to make this product more perfect.

Glancing at Secretary Li who was bragging over there, he didn't know what Secretary Li was in such a hurry for. It was as if someone was chasing him with a knife from behind.

If we come to the grassland for testing at this time next year, he might have already sorted out some technical manuals, and we wouldn't have to teach him step by step here.

"We'll teach you these later. There's plenty of time. Let them fire a few shots first. Can't you see that the squad leaders are getting anxious?"

Li Feng, with his hands in his pockets, did not look anxious at all, but he could clearly see that these old squad leaders were getting anxious. It was questionable how much of the key points could be remembered by the masters' cramming teaching.

Since it's a cannon, let's just fire a few shots first. There are issues that need to be taken into consideration. If we talk too much, wouldn't it make our own products seem somewhat unreliable to outsiders?

"Fight, it's okay, you're all here. If there's a problem, fix it face to face. It's more effective than talking until your lips are worn out. You have to be confident, have confidence in your skills~!"

Seeing that almost everything that should and shouldn't be said had been said, Secretary Li walked to the front of the car body, unscrewed the cover of the cartridge, took out an unfuzed bullet from it, and placed it into the bullet receiving slot of the toggle arm.

When Yang Weimin saw that Secretary Li had taken action, he, who had been standing by without saying a word, immediately took out a fuse from the support vehicle and screwed it on. At the same time, Li Feng also put the propellant cartridge behind the warhead.

"Remember, you have to take out the shells after firing, otherwise the recoil may shake the ammunition out of the trough~!"

Seeing that the explosion was really about to start, Master Jia quickly climbed out from under the car, brushing the snow off his body while continuing to give reminders.

"This thing is really convenient. We don't have to unload the shells from the carriage anymore~!" The old squad leaders looked at the bullet tray on the elbow arm, which rotated backward 180 degrees and delivered the ammunition to the loading port, and they all grinned.

They have been firing artillery for more than ten years, and have been carrying artillery shells for seven or eight years. The 122 bullet and the launch tube weigh more than kilograms in total. Each of them has trained their upper limbs to become strongmen.

Now I suddenly realize that I don't have to carry the shells back and forth anymore. The mechanical structure has replaced manual work. It is really convenient. But when I think about how many years I had to move the shells before I finally made it and became a squad leader, I feel a little unbalanced.

"The buckle here in the ammunition tray is movable. Aim at the barrel, adjust the posture, and then~!"

Secretary Li personally took action, picked up a long pole, aimed it at the launch tube, and directly sent the ammunition into the barrel. Yang Weimin was quick to close the breech block and completed the preparations before firing.

Of course, he was mainly afraid that Secretary Li, whose face had turned red, would not have enough strength and the shell he had finally stuffed in would slide back into the trough.

There is no need to teach the rest of the things. The old squad leaders are more familiar with the gun rope than the other.

"Don't measure the scale data yet, just fire a few shots first to get a feel for it~!"

Throwing away the pole in his hand, Li Feng covered his ears and ran to the side without caring about his image.

When the artillery is firing, the feeling of being next to the gun position is really uncomfortable. After trying it once, Li Feng has learned his lesson. It's not the fault of many artillerymen, as they all have some hearing problems later on. This is the hazard of occupational disease.

After the masters from the Red Star Factory covered their ears and stepped aside, the nine old squad leaders looked at each other, and behaved a little bit modestly in front of outsiders. Of course, it might also have something to do with the fact that their own team leader was standing next to them.

If the captain was not there, Li Feng suspected that there would be a fight. Forget about magnanimity. What the old squad leaders said most often was that they were rough people who didn't know how to reason. They didn't listen to orders. If you made a mistake, he would naturally tell you what reason is.

You let me, I let you, and finally the strongest old squad leader took the gun rope and wound it around his palm. After clenching his fist, he pulled the rope without hesitation.

"Boom~!"

Even the old squad leaders, who were accustomed to standing next to the artillery positions, still subconsciously closed their eyes when the artillery was fired.

The huge recoil force was fed back to the ground through the hydraulic spade. The earth seemed to have turned into the sky, and the snow that had fallen to the ground fell back into the sky.

The azure sky was instantly filled with mist. Compared to the yellow dust that was blown up by the 21st Regiment's firing, the scenery was extremely beautiful when they fired on the snow-covered grassland.

The azure blue sky greeted the cannonballs fired from the gun barrels. The speed of the bullets was so fast that even without blinking, only a blurry shadow could be seen.

In an instant, the warhead was hundreds of meters away, and the naked eye could only observe the turbulence behind the warhead. This was an effect caused by the change of light when it encountered heat, and it would immediately dissipate with a gust of wind.

When the smoke from the muzzle cleared, the sound of thunder could be heard in the distance.

Li Feng raised his hands to cover his eyes. He could hear the sound, which meant the warhead exploded, but he couldn't even see the smoke and dust raised by the explosion. Could this cannon fire at such a long range?

"Why can't I see the impact point~?"

"That's right, you can't see the impact point. That's a depression in front of you. Besides, on the battlefield, only artillery reconnaissance personnel can see the specific impact point~!"

Captain Yue did not take the telescope, as if he was very familiar with the area. After hearing what Li Feng said, he calmly said that he was indeed an expert, but Li Feng was obviously an amateur.

"No need to adjust the posture, just fire a few shots and then adjust later. Look at the dispersion of the bullets landing on the ground and the trajectory. The distance is estimated to be around seven kilometers~!"

Considering that Secretary Li is an outsider, Captain Yue does not mind sharing the answers he has summarized from his own experience with this outsider.

"What is the normal warhead dispersion range? It is acceptable. I also know that the shell cannot fall into a crater~!"

Adhering to the spirit of seeking knowledge, Li Feng knew that if he didn't know something, he didn't know it. He would not pretend and humbly asked Captain Yue for advice.

"Seven kilometers, it should be around seventy to one hundred meters. If the error is too large, it will be too scattered, and the killing effect on living targets will be limited. It still needs to be calibrated. Don't worry, we have enough 122mm shells~!" (End of this chapter)
