On the mountainside.

Du Maoren, who walked out of the fortifications, patted the dust on his head, looked at the vast mountain that was blown by the shells, and vomited a heavy breath that seemed to be filled with the smell of dust and mud, and could breathe normally. It was so good.

To test whether the fortifications built by the soldiers were solid or not, I actually experienced it myself and even brought myself with me. Colonel Liu, who was plump in shape, was definitely the craziest human he had ever seen, no doubt about it.

Liu Lang has no time to comfort everyone in the future kingdom geology.

"How is it, Dakui, how do you feel?" Liu Lang stood in the tunnel, squinted his eyes and glanced at the mountain, and asked faintly.

"The tactics of the reverse slope tunnel allow soldiers to avoid artillery attacks when the enemy fires direct cannons. Although the parabolic dropping method of the curved cannons is a certain threat, it cannot accurately strike the tunnel because the shell landing point cannot be observed, and it is mostly small cannons such as mortars. As long as the fortifications are built strong enough, the enemy's artillery will not have much threat to the reverse slope tunnel." Chi Dakui replied solemnly.

If Chi Dakui does not understand the role of Liu Lang's reverse slope tunnel tactics by using this personal experience, then Chi Dakui, who has been the company commander for several years, can really go home and take care of his children.

The soldiers' eyes flashed, listening quietly to the conversation between the two commanders. What the commanders said were the principles that can be used to save lives at critical moments. Those who are too lazy to listen will be destined not to listen in the future.

"Okay, then I'll ask you again. If the attacking side quickly sends people to capture the edge line after the shelling, that is, your position on the top of the mountain, what should you do?" Liu Lang nodded with satisfaction and continued to ask.

Liu Lang actually wanted to take this opportunity to teach Chi Dakui and these 200 veterans a lesson on mountain defense warfare. As for how much they can learn, they will only know after the war half a year later. Only those who are alive will have qualified academic performance.

The so-called inclined surface is the inclined part from the top of the mountain to the foot of the mountain. The front and back of the inclined surface are relative to the enemy. Take the high ground controlled by both sides as an example. The inclined surface facing the opponent is called the forward inclined surface, and the inclined surface facing the opponent is the reverse inclined surface.

The tactic of the reverse inclined tunnel is to use the enemy's dead ends of artillery on the back inclined surface. Direct aiming artillery fire is a decoration for the reverse inclined surface. There are many dead ends of artillery shells that have been shot to the reverse inclined surface, such as building excavated shooting fortifications under large rocks on the back inclined surface, garrisoning caves, and trenches with roofs. The personnel are basically not exposed to the open air. According to the Black Hawk Army, this is called a cave position.

This way, the enemy's artillery fire will be much less severe.? The reverse slope position has another use, which is to prevent the enemy from surrounding the rear route, such as two mountains, one in front and one behind. In the past, the enemy used artillery fire to suppress the front mountain so that you could not move, and even if you could not retreat, you would not be able to support the back mountain. If he concentrates his troops to occupy the back mountain, you will cut off your back road. The people in the front mountain are basically dead, and the positions cannot be defended, and the people are basically finished.

If you want to do this, first of all, your artillery fire or the plane can't suppress the people in front of the mountain. My main position is facing the back mountain. If you attack the back mountain, go, light your back under the gun of the front mountain. This is called reverse fire. Of course, the reverse inclined position is not impeccable. The key lies in the control of the edge line. Whoever occupys the edge line will have the initiative. If the enemy occupy the edge line, he can correct its mortar and knock off your fire point one by one, and you have no power to fight back. He can even adjust several straight-sighted cannons, and the large-caliber machine gun seals you in the cover to cover his blasting hand to kill you.

The edge line is the outline of the mountain top that can be seen on both sides of the fixed point. In fact, this is also the main position of mountain defense warfare.

Liu Lang asked Chi Dakui that it was the key to the reverse slope tunnel tactics.

"As soon as the enemy's artillery fire stopped, the brothers in the tunnel would definitely rush up and re-enter the position as soon as possible." Chi Dakui replied without hesitation.

I think he has considered the issue that Liu Lang mentioned.

"Did you ever think that the enemy's artillery fire suspension is just a bait? After ten minutes, when you enter the position, he will suddenly launch an artillery bombardment. How much will your loss be?" Liu Lang narrowed his eyes.

I don't know how many tactics have been used in the tactical offensive and defensive battles of the reverse slope tunnel. I have used this way, the White Eagle people have used this way, and the Black Eagle Empire people have used this way, and they have achieved miraculous results in the early stages of the war. Each defensive force has suffered hundreds of casualties before coming up with a countermeasure.

"This...sir..." Chi Dakui hesitated and wanted to speak.

"I know you want to say that you will leave a few observation posts on the main position when the enemy is bombarded, and wait until the enemy infantry starts attacking before notifying the brothers to come up. But you are worried that the enemy's artillery fire will be too fierce, and instead will kill the brothers' lives in vain." He has already stepped on the top of the mountain and stared silently at the trenches that have been blown into scorched earth, and his tone gradually turned sharp: "But have you ever thought that if this place is occupied by the enemy, what will be waiting for everyone will be a disaster? The enemy can block your tunnel entrance with a machine gun. Your entire brothers will die under the enemy's crazy bullets and grenade fragments. They will even have fire spitting soldiers, and your brothers will turn into a mass of coke."

Chi Dakui's face turned red with a swelling look.

Liu Lang seemed to have not seen it and continued, "The ancients said: "Ci is not in charge of soldiers, which means not taking the lives of soldiers seriously. But, where can we win without sacrifice? More than 2,000 officers and soldiers of our independent regiment have no choice but to die for the sake of the great fortune of our kingdom and not being broken by foreign enemies. You Chi Dakui, your soldiers under your Chi Dakui can also die for all your brothers. Do you understand this principle?"

"Of course, it does not mean that when an observation post is dead, the observation post can be placed in a blind spot. Fortifications reinforced with steel plate concrete are enough to withstand the attack of the 155MM howitzer air wave, as long as it is not directly hit." Liu Lang said slightly when he saw the soldiers' solemn expressions of the solemn expressions of the soldiers.

"Sir, what if you are hit directly?" a soldier asked boldly.

"Just hit it directly? Hehe, then you'll finish playing with a bang, and you don't even need to bury it." Liu Lang glanced at the soldier and grinned his teeth.

"Why don't you need to bury me?" The veteran touched his head and was a little confused by Liu Lang's smile.

"I'm stupid, I've become a scumbag, and I'm just burying a lot!" Another soldier replied slowly.

"Oh! If I want to be an observation post, I have to put the valuable things in advance. Lao Zhang remember to help me send the money back to my mother." The veteran nodded naturally.

"Hehe, we will bother each other, then you just don't embezzle mine."

"Get out, who can only like your silver coins? I have saved more than you."

"Haha, I said you didn't go to Yihonglou to play in the county town last time? I've been saving money to get married for a long time. I'll tell you, you're a loss. The butt, thighs, and breasts of a woman in Qiu Tongzhou are soft and slippery."

"Ha ha"

When the soldiers around him heard the conversation between the two soldiers, the soldiers around him burst into laughter.

Everyone was laughing, including the fat team leader who was a little stern just now, although the topic had gone awry.
