With Liu Lang's narration, there are more and more lieutenants, ensigns, and even sergeants who are qualified to come over.

Seeing that the Japanese army on the opposite side was still busy deploying troops and arranging formations, and would not launch a new attack for at least half an hour, Wang Hechun, who had already heard a little bit of the way from it, simply suggested to Liu Lang that it was not good for the big guys to stay in the position and nest in a mess, so it was better to move to the cave, and let Liu Lang continue to tell everyone what anticline tactics and the construction of anticline fortifications were.

It has to be said that Wang Hechun is a very qualified commander, and he knows very well the truth that sharpening his knife is not a mistake for a woodcutter, and after this battle in the morning, he has a grasp of more than 70 percent of the Japanese army's attack in the coming day.

The only thing that worries him is that if the Japanese army really asks for help from the main force of the Eighth Division with heavy casualties as Liu Lang said, and then brings mountain artillery or heavy artillery, then the current level of trenches is basically to deliver food to the Japanese, and maybe the Japanese don't need to launch an attack to bury the 300 or so people under him.

And the anticline tactic that Liu Lang said, although it was only a general idea, but it made him have a flash of inspiration in his mind, it seemed that Liu Lang was very reasonable, but he couldn't grasp that point, and he just wanted him to analyze it clearly.

Of course, the most important thing is that not only he, the supreme commander of the No. 1 position, understands, but also understands the platoon leaders and squad leaders under him, who are the direct executors of this defensive battle.

After obtaining Liu Lang's consent, Battalion Commander Wang quickly ordered Duan Gang to command the officers and soldiers in the front-line trenches to count the captured and continue to dig trenches, and he took the three company commanders and all the platoon commanders and the squad leaders selected by the company commanders into the cave.

Shanzi, a private, as the only one left in the 3rd infantry squad, was directly promoted to the sergeant squad leader, and also followed Li Guobin into the cave, helping his young company commander carry the command knife captured from Changzhi Daxiong.

Li Guobin did not keep it for himself as Wang Hechun said, so that his children and grandchildren would brag about this in the future, he gave the knife to Shanzi and told him that in the future, this knife would be the saber of the squad leader of the 3rd squad, and it would be cool to chop the Japanese devil's head with the Japanese devil's adjutant command knife.

The young private's face was both pride and sadness. He was proud of the knife in his hand, which was the evidence of killing the Japanese invaders, and the greatest glory of the soldiers, but no one shared his pride.

Because, his infantry squad brothers, are gone.

One second to remember: /or

A private-class soldier was carrying the saber of the Japanese adjutant that the division commander and the commander wanted, and a group of lieutenants and old sergeants looked at Shanzi, the new squad leader, with envy, and their eyes were green, but they also knew that this kind of glory did not come for nothing, and there was only this one treasure left for 15 people in an infantry squad, which was the glory of exchanging their lives!

Liu Lang also noticed this scene, and his good impression of Li Guobin, the second lieutenant company commander, increased a lot, and before entering the cave, he patted Shanzi on the shoulder, took off the shell gun hanging from his waist, and gave it to him along with the holster, which was also his reward for the young squad leader.

He hoped that this young soldier would survive this war.

The courage and spirit of Chinese soldiers need to be led by example, just as the great man said: A spark can start a prairie fire!

In the face of such a group of Chinese soldiers who have a strong desire for knowledge and survival, Liu Lang of course knows everything and says everything, and directly takes advantage of the gap in this battlefield to open a martial arts hall in the cave.

In front of more than 20 officers and soldiers who were waiting for their lectures with wide eyes, Liu Lang directly took Master Feng's treasure knife and drew a simple map of the mountain on the stone: "Just now I talked about the importance of the ridge line for the anticline tunnel, originally, the position on the top of the mountain is the ridge line. The trench on the slope behind the mountain is the tunnel, and the purpose of leaving the observation post is to observe the movement of the Japanese infantry and enter the position as soon as the Japanese artillery bombardment, but on the No. 1 high ground, we have no time to re-build the position on the top of the mountain, nor do we have time to complete the tunnel on the slope behind the mountain, so we can completely use another way according to local conditions, to reverse the operation, in my words, called the positive slope fortification. ”

Seeing the stunned faces of the officers and soldiers of the 1st Battalion below Wang Hechun, Liu Lang had to continue to patiently explain: "The main purpose of the anti-slope fortifications is to use the dead angle of the artillery to avoid the enemy's shells, and to strictly guard the ridged positions that are vital to life and death. ”

Liu Lang's broadsword slid on the simple topographic map and continued: "And there is a cave on the No. 1 high ground that can hide thousands of soldiers, once the enemy shells or planes bombard, then most of the troops can be retracted back into the cave through the communication trench, as long as they are not able to blow up this mountain, then this natural tunnel will be fine."

And to be honest, this can also project troops to three positions faster, which is simply a wonderful natural fortification. ”

"Ouch! Wouldn't it be more convenient if we had set up our positions closer to the cave? "A platoon commander patted his thigh and regretted it.

Liu Lang smiled but did not speak.

This one was obviously promoted by a soldier, and he had actual combat experience, but this military theory was slightly worse.

"Pei Heizi, don't talk nonsense if you don't understand! If the distance is too close, there is no depth of the second-line trench, just a trench, Company Commander Li and the 1st Company will be finished in the morning, and they can still chat with you here! The lieutenant who spoke, who was supposed to be his company commander, glared at him, and still explained.

"Aha! That's it! After studying, I have learned, and the chiefs still have a lot of words! The dark-faced ensign shrunk his neck.

The officers and sergeants let out a good-natured laugh.

"Captain Liu, I know that the corners of the trenches you just said are dug to prevent the air waves of artillery shells, but why do you stipulate that the first-line trenches should be dug to a depth of 1.8 meters? There is also an earthen platform on each firing position facing the bottom of the mountain, what is the point of this? Li Guobin asked with some curiosity.

"Haha! That's a good question. Liu Lang smiled lightly. Let me ask you, are we tall or are we little devils? ”

"Nature is our high! Although the little devils are very stocky, their average height is a little shorter than that of our soldiers. Private interjected in reply.

"So! Think about it, our soldiers have to stand on that earthen platform to shoot down the hill, but what if the little devils go into the first line of trenches and want to shoot at our second line of defense, but there is no earthen platform for them to stay? Guess how they will react? Is there still time for them to move bricks? Liu Lang said with a smile.

Although they didn't understand Captain Lang's stalk of moving bricks, everyone burst into laughter: "Haha, then they can only jump and shoot out." ”

"So, if you dig this trench and the front-line position, sometimes you can't lose it!" Liu Lang reminded with a smile.

At this point, the backbone of the 1st Battalion of the army can't admire this person anymore, and they don't know what this brain has in it, even if he has tactical theory and tactical literacy, he is a staff officer of the division headquarters, but the brain melon seed is beyond the reach of everyone present.

He simply calculated all possible situations on the battlefield, not to mention the pride and grandeur that his own trenches would not be lost, and he lost his position in the first row of battles in the morning.

But after using this trick, as this person said, this line of positions can really be lost from time to time.

It was like a trap, and the Japanese troops who entered it were basically unable to attack the second line of defense thirty meters away, while the defenders who retreated to the second line of defense could rely on the advantage of height and throw grenades into the trenches as much as they wanted.

Is it the fat man's big belly, filled with bad water! Looking at Liu Lang with a smile on his face, everyone was happy, fortunately this is from their side! If there is such a fat man among the Japanese, it is very bad.

But now, apparently, the Japanese are going to be much worse!
