Chapter 112 Three Hundred Long Guns Xiao Sen 3

[112] 300 long guns Xiao Sen (III)

The eight learning backbones selected by the third sister are all diligent and hard-working. The process of Yao Fan teaching them trigonometric functions is also very smooth. Yao Fan does not expect himself to teach artillery geniuses, but as long as he can teach them how to measure the distance and check the shooting scale according to the calculation data, and then adjust the artillery shooting posture according to the ruler.

There is a saying about mortars in the army, saying that even new recruits will become sharpshooters after 200 shots.

Although this is a little general, it is not bad. If the battlefield situation allows the gunner to observe the opponent through the optical scope installed on the mortar, then it is almost as simple as a rifle direct shooting. As long as you use the ruler in the scope to measure the distance, high and low angles of the target, and then take the data ruler to adjust the position of the mortar according to the ruler parameters, you can fire.

So generally speaking, mortar crews like to climb hills or hills, which is convenient for direct visual inspection and aiming, saving paper and pen to serve a mess. In this case, the target within 500 meters is the best prey. Of course, if you can't see the enemy, you have to rely on scouts.

It took Yao Fan three days to teach eight students basic trigonometric function knowledge and basic geometry, and then talked about the principle and simple operation of mortars for another day. Then he went straight to gun practice.

Yao Fan prefers this training mode of directly on equipment after a simple explanation. During World War II, the average training time of Soviet Red Army mortars was only 112 hours, 9 hours a day, and he went to the battlefield after about 12 days. The instructor had no time to talk about half a semester of artillery theory knowledge, just on the first day. Review the trigonometric function in the morning, touch the cannon on the spot in the afternoon and start practicing.

Generally speaking, Europe and the United States like this kind of accelerated training, while China pays more attention to solid theory. Not to mention artillery in China, even to learn things like rifle shooting, we should first talk about various principles, parts structure and names, gun decomposition, maintenance, etc., and use a theoretical lesson to eliminate your previous interests and curiosity, and then let you touch the equipment.

This is especially true in the previous period of economic difficulties and military spending, just as the United States shortened the annual flight training time of the Air Force by one month due to the economic crisis.

But theory can never replace practice. It is easy for some people to touch the equipment, but an intuitive understanding is definitely more useful than saying it ten times. In particular, Yao Fan did not come from an artillery background. His artillery knowledge comes from his military fan hobbies, the second comes from the training given to him by the armed police who escorted weapons not long ago, and the third comes from a militia tutorial from the Nanjing Military Region in the revolutionary era, which details the training of rocket launchers and mortars.

The 20,000 practice bullets purchased by Yao Fan are enough for training. As practice bullets, they are not loaded in the front, but only in the back. Training on the soft soil foundation can be recycled 40 or 50 times, that is, the * cylinder can be picked up and reloaded into *.

However, Yao Fan can't make a replaceable * tube for training ammunition at all - even if it is *, that quality can't be produced by handicrafts. At present, even if he barely makes it, he can't guarantee the quality.

Yao Fan took the students, carrying mortars and shells, to a small hill more than 500 meters away from Beiling Mountain. Because of live-fire training, these soldiers who had walked through the queue, practiced fighting, threw training*, and also shot and killed bayonets were slightly Nervous, but not afraid. After all, they have seen much more than most Chinese people this year.

Yao Fan carried a bullet on his back and asked the naughty soldier beside him, "Gui Ba, where are you from?"

"My boss, I'm from Jiaoxi Niu Village."

"Who else is in the family?"

"No, as soon as my father died, my aunt drove me and my mother out."

"How long have you been wandering outside?"

"I ate sea stedling and floated outside for half a year."

Gui Ba held the gun barrel in his arms and pulled out a grass that Yao Fan didn't know from the roadside: "Dongjia, this is rice grass. If you brush the skin, the velvet inside can be eaten."

Gui Ba said and brushed his skin, revealing the white inner stem inside: "Try it, you. It's a little sweet."

Yao Fan looked at Gui Ba's simple smile and put the white inner stem of about two centimeters of rice grass into his mouth: "Well, it's a little sweet and with some powder."

"Ha ha, right, boss, I didn't lie to you." Guiba giggled happily.

"When my mother was here, she often took me to the back mountain of the village. There was a big stone higher than a man on the top of the slope, and the edge was full of rice grass."

Yao Fan smiled gently: "Where is your mother now? Do you live in my Yaojiazhuang?

Gui Ba stared at the road on the ground and strode: "I'm starving to death."

Yao Fan didn't say more.

Everyone finally climbed up this hill about 30 meters high.

Yao Fan guided the soldiers carrying mortars and shells to explain step by step and guide them to assemble the mortars.

"In front of the gunner's gun, the three gunners need to dig the plate pit. Look, just dig such a pit with a side length of 30 centimeters and 10 centimeters deep."

"Only with a pit can it play the role of a fixed mortar... Now a gunner puts the cannon we have just assembled in the pit, supports the barrel, and fixes the stationary hoe hard... Insert the scope into the scope seat..."

"Now the second gunner kneels down on one knee facing the target on the left side of the barrel, removes the muzzle cap, raises the high and low machine... Adjust the high and low bubbles and tilt bubbles on the scope with the first gunner, and adjust the scope to the level..."

"Now let's do what we learned before, and aim for the area on the mountain ahead." Yao Fan pointed to his hand and chose a simple goal for himself.

Yao Fan was afraid of being ashamed, so he took a long time to make sure that it was correct, so he took the shell, pulled out the transportation safety pin, took off the safety cap, and put it into the tube. The shell slipped into the barrel smoothly. "When" sounded, a cannon, a real grenade with No. 0 was shot out by the upright gun body at a 45-degree angle and hit 300 The target on the mortar position on the slope of Beiling Mountain meters away.

A loud noise shocked Yao Fan himself. He saw the smoke rising on the mountainside opposite, and the fire flashed in the white fog and the earth and stone splashed.

"Comrades, this is the power of shells. When you go to the battlefield in the future, your artillery will be the tomahawk of victory and defeat. Wherever you shell, the enemy will be defeated!"

"Dear owner, this gun is really awesome! You don't have to fight against each other to get it. It's really what you said about fighting cattle across the mountain!" Gui Ba, an artillery cadet, gently stroked the dark green gun barrel of Type 87 82, as if he were touching a beautiful girl.

"Okay, now we will train with practice bullets. Everyone starts to follow the parameters I reported, find the shooting table, and adjust the artillery to aim." Yao Fan did not delay for a moment and began teaching when everyone was excited to deepen his memory.

............

"The most taboo thing about mortar training is repeated loading. Sometimes before one shot goes out, you stuff another shot in, that is, the cannon destroys people and kills, and the whole gun squad will die!" After explaining the basics of direct aiming and guiding the soldiers to test a practice bullet, Yao Fan began to explain the most important lesson. In his view, the most dangerous thing about mortars is repeated loading.

In history, when the Soviet army fought against the German army, due to the Soviet army's request for mortars to provide high-intensity rapid-fire fire support, the Soviet mortar artillery frequently made mistakes in the noisy battlefield environment, and there were a large number of repeated loading accidents. In the nine months of the war, there were more than 100 accidents, an average of one every three days. The bomb disaster caused by repeated loading was staged.

At first, the Red Army did not know that it was a problem of misoperation. They thought that the German cannonballs directly hit the Red Army mortar position. Later, more and more surviving gunners reported that the accident was caused by repeated loading, which revealed the truth. The Soviet army went crazy at the thought that there were tens of thousands of mortars fighting on the front line. It was not until the mechanical muzzle safety was designed and installed with the gun barrel that the root of this problem was solved.

Yao Fan changed his gentle temperament and warned the students harshly: "Everyone must pay attention! Be calm on the battlefield! Otherwise, you will make a mistake alone! It will make everyone die!"

The reason why he was so worried was that he had previously considered that the electromagnetic anti-reinstallation insurance independently installed by modern mortars was too high-end for this era. Yao Fan was afraid that if black technology would flow out, it would cause unnecessary trouble, so he did not purchase it. He felt that with the intensity of the war in the 19th century, the soldiers should not be frightened to repeat the loading.

But he did not require Northwest Industry to install the mechanical muzzle safety device invented by the Soviet Union during the wartime. That device will affect the accuracy, range and other main performance of the mortar during installation due to the modification of the mortar structure. Only Russia is still using it in the world, while the West uses photoelectric induction. China uses electromagnetic sensors, which are trying to avoid changing the structure of the artillery.

"Don't think that you won't make such a low-level mistake. You can't imagine the intensity of the battle! When you are tired, nervous, tired and hungry, habitual actions will kill you! Once the first shell appears mute, you habitually stuff it into the second shot, and the two shells will die, killing everyone in the class!"

Yao Fan is almost emphasizing this point with his biggest voice.

"If you hit too many shells in the future, some people may relax. This is a hidden danger. Don't think that the shells will not get stuck! * Failure and gunpowder moisture often cause dumb fire! If there is water or even mud in the gun barrel, it will also jam the shell. If you stuff it in at this time, it is equivalent to suicide!"

"The second gunner must put his hand on the bottom of the barrel. If you can't feel the vibration of the launch, the third gunner will never be allowed to load! Stop it immediately."

"The three gunners are not allowed to fill in the shells without the second gunner's firing command!"

Yao Fan roared with a dry mouth and dry tongue, and his eyes looked at every soldier. Seeing them nodded frequently, he felt a little relieved.

"Now let's learn the correct way to retreat."

Yao Fan ordered the soldiers to lift the back of the mortar. He stood on the side of the muzzle and wrapped his hands around the muzzle.

"Do you see it? Raise it from behind and let the shell slide out by itself. The comrade in charge of receiving the bullet holds it and pulls it out, and then puts it out of a safe distance.
