under fire

Chapter 647

The students are packing up.

Outside the dormitory, Li Huanzhang, who didn't need to pack his luggage at all, was asking Hu Yi for advice: "Brother Hu, last time you said that you want to build this intersecting machine gun position for fire coverage, how many bullets do you need?"

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

As for the cross-fire suppression of guns during positional warfare, the number of bullets required depends on the density of the enemy and the momentum of the attack. Generally, one barrel is destroyed, which is about [-] rounds of bullets. "

Li Huanzhang: "Isn't a barrel only capable of firing about 250 rounds?"

"That's right, isn't it right to change the barrel only once during the battle? Even if you get angry during the battle, the human body can't last that long. The recoil of the machine gun is no joke, and, at the last moment The shooter has to save some bullets."

"I see, how should we hide from the enemy's shelling?"

Hu Yi answered bluntly: "When the enemy's shelling fire is covered, with our current strength, we have almost no power to fight back. We can only focus on concealment. When fighting positional warfare on the plain, as the defensive side, we must first consider digging. Trenches or individual pits, in guerrilla warfare, it is generally rare to encounter heavy enemy artillery.

In addition, when we are attacking, the enemy may launch shelling. At this time, one must pay attention to the screaming sound of the shells flying. "

"I have long heard that there are devils' heavy artillery on the Songhu battlefield. When is the heavy artillery?"

"Heavy artillery is generally defined as more than [-] millimeters, and this type of artillery is mainly used when attacking fortifications.

Guizi heavy artillery mainly has two calibers of 120mm and 150mm. On the Songhu battlefield, Guizi naval battleships have two types of 350mm and 20mm. If you encounter this kind of shell, within [-] meters of the impact point, Even in the trenches, there are basically no survivors.

But the devil's mopping up troops generally don't bring them. At this time, they usually only carry mortars, and they can carry detachable [-] infantry guns if they want to defend against them. "

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

"That thing, we call it a small cannon, is of little use as long as we've dug a standard trench in the field."

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

Seeing that Luo Fugui hadn't come out, Hu Yi simply sat down, pulled out his bayonet and dug a ditch on the ground: "Look, we piled up the excavated soil about one meter high in front of the trench. It's hard to fall into a ditch!

In addition, when digging trenches, the bottom must be sloped to make a bulletproof hole. If you encounter a devil grenade that just fell into the trench, you can kick the grenade into the bulletproof hole with your feet and finish the job. "

"What if it didn't kick in?"

"Either get wounded, or be a good man again in 18 years."

"Hey, I'm taught, I said, why didn't the instructors teach this?"

Hu Yi felt that Li Huanzhang was quite right-tempered. A sharpshooter from the division, he had no airs at all. Maybe a few words of his own could save the lives of one or two soldiers, so he didn't mind telling him first: "The instructor is receiving I will definitely talk about it in the teaching, but you have to remember clearly that when digging trenches, you must choose a favorable location to dig, and after digging, you must pick up all the stones in the soil to prevent them from being destroyed when the enemy bombards them. It may also become a lethal weapon.

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

In positional warfare, trenches play a very important role. Not only are fortifications protecting heavy fire points, crossfire points, headquarters, and temporary rescue positions during battle, they are also carefully set up. In addition, soldiers must dig out a good foxhole "

Before they knew it, a large circle of people surrounded them.

The trainees listened more seriously to the situations that actually occurred in these battles than to learning how to do or plant landmines.

The pigtails in the room finally took shape, wearing a hat with a hole cut out.

"Sister Erniu, what is this 'flowing vinegar'?"

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

"And what is sulfuric acid?"

Er Niuben replied awkwardly: "How would I know? You have to ask Li Xiang."

The girl turned a page: "It's interesting to see a landmine that can jump out and explode in the air."

"That thing is too complicated, I didn't figure it out."

"What the hell is this blooming thunder?"

Erniu continued to help the girl pack her luggage: "When I go back, I will ask the villagers to dig mountains and rocks for me, and plant mines all over the road to kill those bastards who come to sweep up!"

"We don't have that many explosives." The girl replied casually.

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

The girl was speechless for a while, "Grenades are more difficult to deal with than explosives, aren't they?"

Er Niu froze for a moment: "That's what I said."

The girl finished flipping through the book a few times, and she was full of pride: "Okay! The devils always bully us, and our old den of the wine station has been beaten by them several times. When we go back to the plain, the two of us will give all the roads on the plain to the whole country. Plant mines!"

Er Niu froze for a moment: "Okay!"

The big dog who came to urge the two of them to go out quickly shouted at the door: "What a boldness! If you are really so good, how can you let the devils and puppet soldiers survive?"

The girl ignored Tang Dagou's sarcasm at all: "Hey, Big Dog, will you be that kind of thunder that can jump?"

"No, you go find Li Xiang by yourself!" Da Gou was confused, this girl saw the wind and it rained, if she really went crazy, she would have to see if there were landmines on the ground when she went to the latrine in the middle of the night.

"Hey, don't you always brag that you are from the national army's spy company? What are you talking about? How did I recruit you?" That day's really small face was full of surprise.

"Smelly shameless you pretend! If I say yes, why don't you drag me to work as a coolie?"

"Admit it? Hey, after we go back, let's plant landmines at the gate of the devil's barracks in the county!" Those innocent big eyes became more and more excited as they talked, as if they saw the scene of the devil being blown into the sky.

Tang Dagou suddenly felt that he had been fooled, so he quickly bared his teeth, raised his hand and gave himself a mouthful, with a face that would rather die than submit: "Little smelly shameless, you just die of this heart! Even if you threaten me with sweet-scented osmanthus now! Will do it with you!"

"Uh... well, then we can plant mines outside the village, right?" the girl lowered her request.

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

"Hey, did you see this too?" Xiao Zhui'er swayed with a smile.

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

"Big dog, where's the mule?" Er Niu asked with a bag on her back and a rifle.

"Don't ask me, don't you have eyes? Isn't that the one sleeping under the tree over there?" When the big dog saw the girl, he suddenly felt bad.
