Show the sword, start from the guerrillas

Chapter 81 Chapter 081, I still have to teach mathematics
"Let me first explain how to operate this telescope!" Li Yuexuan looked at the students' puzzled eyes, and then said: "Our Eighth Route Army is very poor, but we can't always be so poor, right? For example, Comrade Zhang Chong, you have made great contributions in this battle. When the new regiment was reorganized, why didn't Commander Li Yunlong give you a platoon leader position?"

"We seized quite a few telescopes in the battle a few days ago. Why can't I share one with you?" Li Yuexuan said to Zhang Chong.

"Report! I am now the platoon leader!" Zhang Chong raised his hand and said loudly.

"See, I told you! Okay, now I'll tell you how to use this telescope! When you hold the telescope in your hand, you must first adjust the pupil distance and the eyepiece. After adjusting the pupil distance, you will see a circular field of view with a cross-shaped scale in the middle. And to adjust the eyepiece, you need to adjust it according to your vision!"

"Then the question is, how do you use a telescope to measure distance? Do you see that branch over there? I know it's exactly 2 meters long, and it occupies 10 mils in my telescope. Here's a formula, which is to multiply this length by 1000, and then divide the mil number. In this way, we can calculate that the distance between this stick and us is 200 meters."

"Of course, not every target has such a standard, so you need to make detailed calculations!" Li Yuexuan said, then took the telescope in his hand and said to the students: "Next, come up one by one and observe the scene you see through the telescope so that you can have a clear idea! Then, captain, can you please contribute your telescope?"

"Ah...haha, that's fine!" Xing Weiguo came over with his telescope. Many telescopes were captured in this battle, and Xing Weiguo also got a Zeiss telescope. The guerrillas were really awesome.

In the following time, the students came up one by one like curious babies and looked at the wooden stick through telescopes. Comrade Bai Dabao's work was not in vain.

Okay, everyone has seen it, but there are some details that you don't understand. Let me explain them to you. The cross division you see, each small grid is 5 digits, and 1 large grid is 10 digits. If you don't understand, just think about the beam balance we use, think about the stars, and you will understand.

"The distance measurement of a telescope is actually that simple! The difficult part is the calculation process!" After Li Yuexuan finished speaking, he saw some comrades with confused eyes, and he was shocked. These people don't know basic addition, subtraction, multiplication and division, right? It shouldn't be like this?
After thinking for a while, Li Yuexuan continued, "Each of you has a different arm length and pupil distance, that is, the distance between your two eyes. So each of you has your own proportional data for measuring distance with the naked eye, so this calculation is relatively simple. When using this precision calculation, there is one more division... How about I give you some extra lessons in the evening?"

"Haha, this is possible!" Xing Weiguo laughed happily on the side, and he gave this job to Li Yuexuan.

"That's it! Today's training ends here for now. After dinner, I'll teach you some simple addition, subtraction, multiplication and division. OK, now dismissed. If you have any questions, feel free to ask."

"Report! Instructor, the situation on the battlefield is complicated. How do we choose a suitable reference object? Or how do we judge the length of the reference object?" The question was asked by the chubby Yu Xiaoyu.

"Xiao Yu's question is very good. This is probably the most common question among comrades! Then, I will give you a simple method - practice more, get more exposure! The more you see, the more you will know! Of course, this method requires a lot of time to accumulate, so there is another way, that is to preset the battlefield!"

"For example, when we ambush at the Dragon King Temple, we have chosen the ambush location, and the comrades are hiding or digging bunkers. You have an extra job, which is to understand the surrounding environment, find a target that can be used as a reference, and then master the data of this reference, so that you can perform measurements and calculations. This reference can be used not only with a telescope, but also with the naked eye to measure distance."

"There is an even dumber way to preset a battlefield, which is to measure a distance yourself, find a suitable reference point on the battlefield, and memorize the distance data around this reference point. The best way is to draw a simple topographic map, then draw fences, mark the distance of each fence, and also mark the several battle positions you have set."

"So, when you want to bomb a certain enemy, just look at the fence area where the enemy is located, and you can adjust your shooting calmly! This method is actually more suitable for mortar bombing! Use the fence to separate the target area to be bombed. Each mortar controls several areas, and you only need to bomb these coordinates during the battle!"

"Also! Who are our main combat targets? The Japanese devils and the puppet army, right? Well, no matter they are the devils or the puppet army, they must carry guns, right? Then, you must master some gun length data! For example, the length of the Type 38 rifle and the length of the Hanyang rifle, you must remember them. In addition, you must also remember the distance from the trigger to the muzzle of the Type 38 rifle..."

"The other thing is height! Little Japanese soldiers, little Japanese soldiers, you have all seen their height. The tallest ones are no more than 1 meters, and the shortest ones are about 55 meters. If it's hard to judge, just look at the guns they carry! This is the ready-made data! And how wide the Japanese helmet is, how wide the backpack is, how long the Type 1 heavy machine is... These are all fixed data, and you can even make advance calculations in advance!"

"You can even make pre-calculations in advance and remember the data! Well, I'll find some time to write a table for you! The reference objects are the Japanese and the Type 1 rifle. From 20 digit to digits, they are all calculated and listed in the table for you. Although you can't use it for the time being, you can use it when you need it!" said Li Yuexuan.

"Okay, thank you instructor!" Zhang Chong said loudly in the crowd and even applauded.

Hualala... Everyone applauded, and Li Yuexuan raised his hand to stop them. Then, he said to Zhang Chong: "Tonight, do 20 more push-ups! But my comrades and I will do it with you! By the way, do you know what push-ups are?" Li Yuexuan asked. "Report, I really don't know that!" Zhang Chong said.

"Okay, whether you know it or not, I'll do a few sets for you and you watch!" After saying that, Li Yuexuan handed the telescope to Xing Weiguo, lay on the ground, and started doing 50 push-ups.

"Is this push-ups? I used to do this when I was practicing martial arts, but I really don't know what this movement is called!" Xing Weiguo was watching curiously from the side. He handed the telescope to Bai Dabao and did a few sets as well.

Seeing the instructor and Xing Weiguo going up and down there so coolly, the students couldn't bear to watch anymore. They found a place, stretched out their hands, and started doing push-ups.

Li Yuexuan's physical fitness was already able to easily handle 5 push-ups in 280 minutes, so he quickly completed 50 push-ups in 1 and a half minutes. When he stood up, he looked at the students lying on the ground with interest, and reminded those who were not doing it to the standard.

"Well, they are all good. You have the aura of veterans of the main force! We have a day off today, so let's practice more. Just lie down and do it over and see what your highest record is." Li Yuexuan walked among the soldiers without stopping and even encouraged himself.

"One, two, three, straighten your shoulders, hold the gun with your strong arms; four, five, six, switch to fists, beat the devils with all your strength! Seven, eight, nine, follow the party, the victory of the revolution is beckoning..."

“We may shed blood and sweat, but we won’t shed tears. We may lose skin and flesh, but we won’t fall behind! I sweated a lot during today’s training, but I will be a hero on the battlefield!”

“Raise your guns, we are soldiers! Keep danger away from ourselves and leave safety to the people! On the battlefield, we are the Great Wall of Steel, and when we see the people, we are the closest soldiers!”

Li Yuexuan kept talking, and the soldiers' blood boiled. Then they kept doing push-ups, panting, until... they couldn't hold on any longer.

"Okay, comrades, the training is over, get up and take it back!" Seeing the comrades sweating all over, Li Yuexuan sighed in his heart that these veterans had really good physical fitness.

Well, at least, I did more than 300 push-ups! Although there is no time limit, but... those who see this can try to do 30 in one go...

The trainees were brought back. Li Yuexuan's slingshot and Bai Dabao's bow and arrows performed well on the way back, and shot down another five pheasants and three squirrels. So, for dinner tonight, there was pheasant stewed with rabbit and fried squirrel meat. These meats made the soldiers who had not seen meat for several days very happy, especially the new recruits, who ate them with gusto.

After dinner, three lanterns were lit in the yard, illuminating a blackboard that had just been made of pot ash. Then, Li Yuexuan took a piece of white ash and wrote down on the blackboard with difficulty... the multiplication table! Yes, it was the small multiplication table! Although there was also a big multiplication table, Li Yuexuan said that this was too difficult, and comrades only needed to master the small multiplication table.

Then? Then the courtyard was filled with neat one-one-one, one-two-two…

While they are learning the multiplication table here, in the yard next door, the new recruits are receiving cultural lessons from their captain.

Well, it’s very simple. It’s just the basic Chinese characters: one, two, three, four, five, water, wood, metal, fire, earth, heaven, earth, man, wind and thunder.

In short, the party's troops are culturally and disciplined. New recruits must not only undergo military technical training, but also cultural learning! This is very important, because culturally and disciplined troops have excellent combat effectiveness. Captain Jiang of the transport brigade said that he has a deep understanding of this.
