Students are cleaning up.

Outside the dormitory, Li Huanzhang, who didn't have to pack his luggage at all, was asking Hu Yi for advice: "Brother Hu, last time you said you wanted to set up this cross-machine gun position for fire coverage, how many bullets are needed?"

Hu Yi immediately corrected Li Huanzhang's mistake: "Intensive firing of light and heavy machine guns is generally called fire suppression, not fire coverage. What is usually called fire coverage is mainly to saturate enemy positions with artillery or aircraft bombs."

attack.

As for the cross-fire suppression of positional combat machine guns, the number of bullets required depends on the density of the enemy and the momentum of the attack. Generally, the number is based on the destruction of one barrel, which is about 400 rounds of bullets."

Li Huanzhang: "Isn't it true that one barrel can only fire about 250 rounds?"

"Yes, isn't it right to only change the barrel once in a battle? Even if you get angry during the battle, the human body cannot last that long. The recoil of the machine gun is no joke, and in the end, the machine gun

The gunman still has to keep some bullet reserve."

"I understand, but how should we hide when faced with enemy bombardment?"

Hu Yishun replied: "When the enemy is covering the artillery fire, with our current strength, we have almost no power to fight back and can only focus on concealment. When fighting positional warfare on the plains, as the defensive side, we must first consider digging

In trenches or individual soldier pits, in guerrilla warfare, it is generally rare to encounter enemy heavy artillery.

In addition, when we are attacking, the enemy may launch artillery fire. At this time, we must pay attention to the scream of flying artillery shells, and when defending against artillery, we must use our elbows to prop up our bodies and not press our bodies to the ground."

"I've long heard that there were Japanese heavy artillery on the Songhu battlefield. When exactly did the heavy artillery appear?"

"Heavy artillery is generally defined as over 105 mm. This type of artillery is mainly used when attacking fortresses.

The Japanese heavy artillery mainly has two calibers: 120 mm and 150 mm. On the Songhu battlefield, the Japanese navy battleships had 356 mm and 410 mm calibers. If you encounter this kind of shells

, within twenty meters of the impact point, even in the trenches, it is basically impossible for survivors to appear.

But the Japanese's mopping up troops generally don't bring them. At this time, they usually only bring mortars, and they can bring the detachable 92 infantry cannon. They can defend themselves how to defend themselves."

"What about the grenade? The Japanese can hit that thing very accurately. How should we deal with it?"

"That thing, we call it a small cannon, is almost useless as long as we dig standard trenches on the battlefield."

Li Huanzhang shook his head in disbelief: "How is that possible?"

Seeing that Luo Fugui had not come out, Hu Yi simply sat down, took out his bayonet and dug a trench in the ground: "Look, we piled the excavated soil about one meter high in front of the trench. When the enemy's grenades hit the formation, we

It's hard to fall into the ditch!

In addition, when digging trenches, the bottom must be sloped to create a shell-proof hole. If you encounter a Japanese grenade that happens to fall into the trench, you can kick the grenade into the bullet-proof hole with your feet."

"Then what if we don't kick it in?"

"Either you get injured in the bombing, or you become a good man again in eighteen years."

"Hey, you've been taught a lesson. I asked, why didn't the instructors teach you this?"

Hu Yi felt that Li Huanzhang was quite good-tempered. He was a sharpshooter from the division and had no airs at all. Maybe he could save the lives of one or two soldiers with a few words. He didn't mind telling him first: "The instructor is picking up the answer."

I will definitely talk about it in the next tutorial, but you have to remember clearly that when digging trenches, you must choose a favorable location to dig. After digging, you must pick up all the stones in the pile of soil to prevent these stones from being destroyed when the enemy shells them.

It may also become a lethal weapon.

Under normal circumstances, the depth of defense trenches plus piles of soil should be about two meters, and the depth of traffic trenches should be at least about 1.5 meters.

In positional warfare, trenches play a very important role. They are not only for fortification protection during battle, but also for the protection of heavy firepower points, crossfire points, command posts, and temporary rescue positions. They are carefully set up. In addition, soldiers must dig a good foxhole.

..."

Unconsciously, a large circle of people surrounded the two of them.

The students listened more carefully to the actual situations that occurred in these battles than when they were learning to lay landmines.

...

The braid in the house finally showed its original shape and put on a hat with a hole cut out.

"Sister Erniu, what is this 'jealousy'?"

Erniu put her head close to the book in the girl's hand: "This is sulfuric acid!"

"What is sulfuric acid?"

Erniu replied awkwardly: "How do I know? You have to ask Li Xiang."

The girl turned a page: "This mine that can jump out and explode in the air... is quite interesting."

"That thing is too complicated, I don't understand it."

"What the hell is this Hua Lei?"

Erniu continued to help the girl pack her luggage: "When I go back, I will ask the villagers to dig up mountains and stone mines for me, lay mines on all the roads along the base, and blow up those bastards who come to raid!"

"We don't have that much explosives," the girl replied smoothly.

"If you don't have it, ask Qianjiu to buy it. He still owes me a lot of money." Erniu thought for a while: "If it doesn't work, let's dismantle the grenade!"

The girl was speechless for a long time and said, "Grenade is more difficult to deal with than explosives, right?"

Erniu was stunned for a moment: "That's what I said..."

The girl finished flipping through the book in a few times, and suddenly said with pride: "Okay! The Japanese always bully us, and we were beaten several times in our hometown of the wine station. This time when we go back to the plain, the two of us will fight all the roads on the plain."

Lay mines!"

Erniu was stunned for a moment: "Okay!"

The big dog who came to urge the two of them to go out quickly shouted at the door: "You are so brave! If you are really so awesome, how can you let the Japanese and puppet soldiers survive?"

The girl didn't pay any attention to Tang Dagou's sarcasm: "Hey, Dagou, can you do the kind of thunder that can jump?"

"No, you go find Li Xiang yourself!" Dagou was deceived in his heart. This girl is like rain when she sees the wind. If she really goes crazy, she will have to check whether there are any landmines on the ground when she goes to the latrine in the middle of the night.

"Hey...don't you always brag that you are from the National Army's special agent company? What are you talking about? Where did I recruit you?" A look of surprise appeared on Tianzhen's little face.

"You are so shameless, keep pretending! If I say yes, why don't you drag me to work as a coolie?"

"Do you admit it? Hehe, when we get back, let's go to the gate of the Japs barracks in the county to plant landmines!" Those big innocent eyes became more and more excited as they spoke, as if they saw the Japs being blown up into the sky.

Tang Dagou suddenly felt that he had been deceived, and quickly bared his teeth and raised his hand to give himself a slap in the face, with a face that he would rather die than surrender: "Shameless little brat, just give up on this! Even if you threaten me with Osmanthus fragrans now...I will also

I won’t fuck with you!”

"Uh... Okay, then it's okay for us to plant landmines outside the village, right?" The girl lowered her request.

"Hurry up and get out! I won't be fooled by you. You shamelessly said that outside the village... Who knew that the outside of the village would be dozens of miles away from the village?"

"Hehe, have you noticed this too?" Xiaobian'er was shaking with laughter.

The big dog pulled a backpack from the house and hung it on his shoulder and went straight out. Before leaving, he said, "You women are so troublesome!"

"Big dog, where's the mule?" Erniu asked, carrying a bag and grabbing a rifle.
