Show the sword, start from the guerrillas

Chapter 77 Chapter 077, unfortunately I can only provide information

Li Yuexuan's current identity is somewhat special! You can say that he is a guerrilla fighter, his identity is a guerrilla fighter.

However, in addition to the guerrillas, he also provided the organization with a document on sulfa drugs. Although the accuracy of the document has not been verified, those who can provide this document should not be placed in combat units, and it is best to send them to the research unit of the logistics department. However, since he is a new member, he still needs to be observed, so he was placed in a combat unit.

Today, because he blew up a large number of Japanese soldiers with grenade launchers in battle, and the troops were also troubled by the Japanese grenade launchers, so based on the principle of using grenade launchers to defeat grenade launchers, he became a grenade launcher instructor! And this instructor is for the entire army.

It's not that no one on the Eighth Route Army knows how to use grenade launchers. After all, there are many capable people in the Eighth Route Army! However, the one who has killed the most enemies with captured grenade launchers in the Eighth Route Army so far is Li Yuexuan.

It just so happened that Li Yuexuan was resting and training here with the guerrillas. Both the Jin-Cha-Ji side and the 129th Division would naturally not miss this time.

Li Yuexuan, a new official, naturally had to write a training textbook for grenade launchers! With the textbook, some students, and then they could start training. After the training, the students took the textbook to their original units, and then it would blossom and bear fruit in various units like seeds.

Although not every unit has captured grenade launchers, what if one is captured one day? If there are grenade launcher soldiers in the unit, if the grenade launcher is captured, it can be used to kill the enemy!

During the rest of the afternoon, Li Yuexuan took out the half notebook that Zhao Danian gave him, took out a pen and pencil, and began to write on the notebook.

In fact, the Japanese grenade launcher is really simple, and you only need to pay attention to a few points to launch it. So Li Yuexuan only used three pages of paper to write down all the things that need to be paid attention to, and then summarized some tactical coordination of the grenade launcher.

When he finished writing, he always felt that the three thin pages of paper were a bit embarrassing, so he simply opened them again and prepared to write something else.

"Research on data on domestically produced grenade launchers! Well, let's call it this title!" Li Yuexuan muttered to himself and wrote down this title.

Then, he opened his virtual phone, searched for all the information about the Dinglong grenade launcher, and then sorted out a suitable content bit by bit. After finishing the sorting, he started writing.

"The Japanese Type 89 grenade launcher is a weapon that launches grenades at high and low pressures. There are rifling in the middle of the barrel and a copper sealing ring on the projectile body. It is not suitable for the Eighth Route Army to produce and imitate. Therefore, I designed and modified a grenade launcher based on the premise that the production capacity is extremely low and the mechanical level is almost zero."

"First, the barrel of the grenade launcher adopts smoothbore shooting, with an inner diameter of 50mm, and the barrel is lengthened to 40cm to increase the range. The barrel material can be made of imported steel drills or railway rails, which can be produced after forging... The specific forging process and information are shown in the figure..."

"The second point is the scale of the grenade launcher. The scale of the Type 89 grenade launcher uses a threaded launch base to control the depth of the grenade in the barrel to control the distance. If it is produced, a large number of threads need to be processed. It is too difficult for us to imitate it, so we abandoned this method and adopted a fixed barrel depth like a mortar, using the launch angle for distance control. Angle control can be carried out in a plumb manner. The disk scale plumb instrument composition..."

"The third point is the projectile body! The imitation grenade launcher is not suitable for using the original ammunition of the Japanese grenade launcher, and needs to be produced by itself. The structure of the projectile body is based on the shape of a mortar shell, and has its own tail fin..." Li Yuexuan wrote and drew, and soon added another 10 pages of information, and then nodded with satisfaction.

After finishing writing, I thought about it and remembered that the source of cast iron for the Eighth Route Army was also very small at that time, so I searched for information again and wrote down the information on how to use the crucible method to smelt white cast iron in small batches into gray cast iron. Well, it was just a simple writing of several pages, and the specific details still required professional talents to conduct experimental production.

Li Yuexuan was writing here, and the guerrilla comrades once again deliberately avoided him. He did not stop writing until dinner time.

After dinner, it was getting dark. Li Yuexuan found Zhao Danian and said, "Captain, is there a suitable place on the mountain for training? And for their training, do we need live-fire shooting lessons? We can't afford the ammunition. Does the organization have any ammunition for training?"

"Haha, I thought you wouldn't ask these questions? The organization has already considered these issues. Those who can come here for training all bring grenades! Each person brought 10 training shells! What do you think? Do you have the confidence to let them use these 10 training shells to become god gunners?" Zhao Danian said with a laugh.

"I have confidence, but it depends on how hard my comrades work! They all know how to measure distance, right? If they can measure distance, then training will be easy!" Li Yuexuan asked.

"Yes, I know all of them! These are the basic requirements for grenade throwers!" said Zhao Danian.

"That's good! By the way, I wrote a document. Please read it with a lantern. If you think it's feasible, find a chance to send it to the organization!" Li Yuexuan gave the newly written textbook and the production materials of Dinglong grenade launcher to the captain. As for trust? If Zhao Danian was not trustworthy, Li Yuexuan would not have stayed in the guerrillas and would have been transferred to other places long ago.

"Let me see..." Zhao Danian turned on the lantern and started to look. The more he looked, the happier he became, and then he was surprised and delighted.

"You...can we do this ourselves?" Zhao Danian asked, pointing to the information at the back.

"Yes, of course we can! We have so many troops, so we must have the talents! We just need to concentrate our efforts on major tasks, gather together these technical talents, and gather all the machinery and equipment that can be found. We should be able to make this, right? I heard that some gunsmiths can make rifles with simple equipment. In fact, we can also try it!" Li Yuexuan said.

"Hmm..." Zhao Danian closed his eyes and thought for a moment, then asked, "You should be able to remember this information, right? Hey, my brain, can't you remember what you wrote yourself? Haha..."

After an awkward smile, Zhao Danian stood up and patted Li Yuexuan on the shoulder, then said, "Have a good rest tonight. Lao Xing will help you with training tomorrow. Huyan Long, Huyan Bao, Zhang Lu, and Bai Dashan will also train with you! Tian E, go get two horses, bring a flashlight, and let's go to the third division in the south!"
