Although the two were arguing like two children, Yang Muhua grew up, and no boy dared to face her and say that he liked her.

At this moment, although she was bickering, after all, she heard such a sentence with her own ears, and she was shocked at that time, she was speechless for a while, her face was flushed, and she was so angry that she almost cried, but with a trace of indescribable sweetness, she fled in the wilderness.

Sangou was still immersed in the atmosphere of quarrels and bickering at the beginning, looking at the back of Yang Muhua who fled in defeat, with a shameless smile, he couldn't help but feel a little proud of the winner.

But when I think about it, I feel very sorry for others, after all, they are interceding with her friends, and she can't be so rude and quarrel with others.

It's just that the words that are said are the same as the water that has been spilled, and they can't be taken back, what should I do? Apologize to go? How to apologize? Dryly go to find someone, in case they are still angry and ignore me, wouldn't I be even more embarrassed.

Looking for someone to intercede? What's more, the less people know about this matter, the better, and finding someone to go is tantamount to making the matter public, and people can't accept it.

Let's talk about it later, besides, they are just substitute trainees of the military medical school, and they will leave after a while, and in the future, they will basically not be able to see them.

Even if I see the above, people won't necessarily be friends with me, not even ordinary friends, at most it's just a nod, just for a nodding friend, and there is no need to go around for this.

The past is gone, everyone has their own life, and the next course is not very easy, so let's go to study; Thinking of this, Sangou hurried back to the dormitory.

This time it was okay, because the trumpet for self-study in the evening had already sounded, and a bunch of heads crowded on the window hurriedly separated, each looking for books and materials, and hurriedly went to the classroom.

When he went to bed at night, Sangou was waiting for the arrival of the dormitory storm, but no one mentioned this matter for a long time, as if everyone had not mentioned this matter unanimously.

It's strange, according to the previous strength, Sangou and Yang Muhua have been talking for so long, and Sangou has to tear these guys apart when they go back, but now, it's as if nothing happened.

Perhaps, everyone saw Yang Muhua leave angrily, and vaguely guessed something, it is estimated that Guan Dingjie's guy did something to be sorry for her, and this kind of thing may be very sensitive and not suitable for catching Sangou to ask in the end.

Although everyone usually smiles and squeezes each other, they will be very cautious when it comes to formal occasions and formal things.

After all, they are all people who want to save face, not to mention that Yang Muhua is a yellow flower girl, and if she can save face for others, she has to save face for others.

So although everyone had 10,000 curiosity in their hearts, they wanted to ask Sangou what happened to Yang Muhua and Guan Dingjie, but when the words came to their mouths, they all stubbornly suppressed the words that should not be asked.

It's just that everyone has a helpful heart for Yang Muhua, and there is no power to help; I can't wait to catch Guan Dingjie, the hypocrite, Haibian beat him, so as to vent the anger in his heart, those who like Yang Muhua openly and secretly, even more.

……

Sangou has insisted on not going to Lin Shuxian, even if occasionally in the entertainment time after dinner, everyone is together on the playground, Sangou is the same as before, most of the time is a dispensable participant, but Yang Muhua has never intersected with Sangou again.

However, when it comes to the in-depth course, whether it is a cultural class or an outdoor technical subject, it is becoming more and more difficult.

Although the infantry section does not need to learn very detailed and professional artillery knowledge, it must master some mortars that infantry needs to use, including grenadiers.

It is also necessary to have a rough grasp and familiarity with some combat defense guns, infantry guns, and mountain artillery equipped with infantry; For field artillery, howitzers, heavy artillery, and even anti-aircraft guns, it is also necessary to understand.

At that time, the mortars mainly equipped by the infantry were imitations of the British Stokes mortars in the 12th year of the Republic of China (1923), called the "Shanghai-type" 82 mm mortar, the whole gun weighed 68 kg, the bullet weighed 3.8 kg, and the maximum firing range was 2.8 kilometers.

Later, in the twentieth year of the Republic of China (1931), Nanjing Jinling Arsenal imitated the French Brandt-type 81-mm mortar, called the "Twenties-type" mortar.

In 1932, a mortar factory was formally established in Nanjing, mainly producing 82mm mortars; It was these two mortars of 81 and 82 that the left instructor bringed

Note: In the middle and late stages of the Anti-Japanese War, 50, 60, 105, 120, and 150 mm mortars were imitated and imported. The Japanese army has 80, 89, and 120 mm mortars.

Mortars are muzzle-loaded, curved smoothbore guns that fire tail shells, and can shoot at targets behind shelters through parabolic shell falls.

Mortars were born during the Russo-Japanese War and later modified by Britain and France, although simple but have incomparable advantages in mountain warfare, and are still one of the standing weapons of infantry in various countries.

Mortars have the characteristics of short gun body, large firing angle, high ballistic arc, high lethality, easy operation, light and flexible, so since its inception, it has been an effective suppression weapon to support and accompany infantry operations, and is an extremely important conventional weapon for infantry.

However, due to the backwardness of the military industry, the national army was not equipped much, only the division and regiment level could be equipped with 82 mortars, and after the start of the Anti-Japanese War, 60 mortars were equipped at the battalion and company level of the A division (each battalion has an organic artillery company, equipped with 4 heavy machine guns and 2 mortars).

Instructor Zuo briefly introduced the mortar, and then focused on explaining several aiming methods of the mortar, in the classroom in the book, the instructor also talked about the method, very detailed methods, but in the field, it is still different, everyone learns while practicing.

The first gunner is the aimer, carrying the scope and the gun body, the second gunner carries the gun carriage and loads the shells and cooperates with the first gunner to aim, and the third gunner carries the seat plate and passes the shells.

The mortar is a curved artillery, according to the firing table to calculate the firing elements, set the left and right directions, there are angle plates, each scale represents how many meters, each gun has a set when it leaves the factory.

Set and fine-tune the left and right directions, and then adjust the muzzle to this distance according to the target distance, plus factors such as air temperature, medicine temperature, wind direction, wind speed, and height difference, even if it is aiming.

There is also a target distance measurement, there are several temporary soil methods, that is, the jumping eye method of ranging, facing the target, stretching out the right thumb between the eyes, closing the left eye, and using the right eye to aim at the target through the side of the thumb.

Then use your left eye to look at the same side, remember the object that your left eye is looking at, estimate the distance between the object and the target, and then multiply it by ten times to get the distance of the target.

Other methods include arm length measurement, autologous distance measurement, military telescope measurement, visual distance measurement, etc., as well as day and night distances based on vision, target clarity and practical experience.

As for the situation of fighting across the mountain, an observation position was set up on the top of the mountain, and the relative positions of the observation, artillery, and target were measured with optical equipment (steering wheel, artillery mirror), and the shooting was calculated into firing elements, and the artillery position was notified.

These jobs, like over-the-horizon cannon aiming, belong to the artillerymen; But if the infantry can master it, it is even better, and they can call in artillery and provide artillery support; However, this was an idealistic thing for the Chinese army and infantry in that era.

After determining the shooting elements, test firing the shells, and then according to the direction and distance deviation between the shells and the target, make the revision of the shooting elements, and then shoot, generally 3 adjustments are basically accurate.

For the national army, mortars are high-end weapons, and the ammunition is not very sufficient, so they need to be spared, so the gunner is required to calculate the distance very accurately.

The gunners of the Japanese army were very powerful, why, like other riflemen, they were fed with ammunition during training, and after fighting many times, practice naturally makes perfect.

The artillery of the national army, on the other hand, is reluctant to use ammunition and has very little training in peacetime, so naturally no one is powerful after going into battle, and when fighting mortars against the enemy, they will fall behind.

These words were secretly told to everyone by Lao Hei after the Instructor Zuo left, and if you fight with the Japanese army in the future, you must be very careful of the Japanese mortars, especially the machine gunners.
