In fact, the Japanese army's large-scale transformation from brigades to divisions only began around 1942.

This is historical.

Including the current Japanese 58th Division, it was only in 1942 that other brigades began to expand.

In February 1942, Shimono Kazuhiro served as the first division commander of the Japanese 58th Division after its reconstruction.

Including other divisions, they are all the same. After 1942, each brigade was expanded, and 1 to 2 infantry regiments or other regiments were added to expand it into a division. A division generally controls 3 ~4 infantry regiments, plus artillery battalions, cavalry, engineers, and other troops such as baggage troops.

However, most of the expansion at that time was from the brigade to the division level. The reason for abandoning the brigade level was to go south to Southeast Asia.

But now this is the world of Liangjian. If there is no Chen Shanhe in this world, and the original plot is followed, this area is the territory where the Japanese army merged into the 4th Brigade and merged into the 9th Brigade and the 29th Brigade.

But now.

Because of the existence of Chen Shanhe's independent second regiment, the brigade commander who became the fourth brigade was removed and replaced with other positions. Then, after adding an engineer regiment to the fourth brigade, it became a division. .

And this Japanese division specially added an engineer regiment to deal with Chen Shanhe. A mere regiment could actually fight against a brigade, one against eight, and the ruthless man was unscathed.

really.

Now, as soon as the engineers took action, they immediately dug up several modified mines on the ground that could not be detected with mine detectors.

And after the engineers carefully removed the detonating device of the mine, and then moved out the large and heavy earthenware mine.

The captain of the Engineer Regiment of the 58th Division of the Japanese Army couldn't help but sigh when he saw this urn containing almost a hundred kilograms of explosives.

"An ingenious mine.

Use a thickened earthenware urn as the shell of the mine, and fill it with more than 80 kilograms of black powder, and use 40 kilograms of gravel at the mouth of the urn to supplement the splash damage.

It is a very ingenious design. No wonder our army suffered heavy casualties when encountering this kind of landmine.

Even if he is not killed by the explosive power of more than 80 kilograms of gunpowder, he will be killed by the gravel caused by the explosion.

No wonder...our mine detectors cannot detect landmines. It turns out that there is no metal on the landmines, so there is no metal reaction at all!"

The Chief of Staff of the Engineer Regiment said proudly: "Although the enemy's ingenious mine detectors are really indiscernible.

However, the mine detection rods we rushed to make are still very useful. If the mine detector cannot detect, use the mine detection rods to detect.

If the mine detector and the mine detection rod are used and there are still missing items, the chance will be one in a thousand or even ten thousand!

This is the value of engineers!"

The mine detection stick is a long pole with an iron stick in front, which allows little devils to poke the mines underground, just like how some people would use this stick to poke the tortoises in the water decades later.

It doesn't have any high-tech technology, it's just a long stick with a sharp iron pick on the front, which can be inserted into the ground to find whether there are any big obstacles.

But this seemingly simple and crude thing can actually solve the current dilemma of the Japanese army attacking the base area of ​​the Second Independent Regiment of the Eighth Route Army.

No one likes to walk on a land full of mines, whether it is a hillside or cliff, or in the fields on both sides of the road.

As for the road, that goes without saying.

Wherever the Japanese troops passed through, they encountered landmines.

Therefore, after a series of encounters, the Japanese army could only continue to move forward along the road to clear mines.

This is called a steady and steady approach. Compared with fields, slopes and rivers, roads are the best environment for demining.

"Captain, our landmines have been dug up by the little devils. What should we do?"

Chen Shanhe sent people to lay mine formations in any direction where the Japanese army advanced. The formations they worked so hard to set up were actually broken by a Japanese engineering unit with a steady attack.

Looking at the several large landmines dug up by the Japanese army, Chen Shanhe groaned: "It's a pity that I have several large landmines. Each of these landmines contains almost a hundred kilograms of gunpowder!"

It’s a bit of a waste to just dig it out like this!”

In fact, the first method of mine warfare is to deploy a permanent minefield on the border or in a certain place for a long time.

There is another way, which is to have a complete intelligence system, wait for the Japanese army to come, start laying minefields in the area where the Japanese army must pass, and wait for the Japanese army to leave, and then dig out all these mines.

The first method saves time and effort, but it is not very friendly to the people and can easily injure them accidentally.

The second method is what Chen Shanhe is doing now. Using a complete intelligence system, he can clearly know the movements of the Japanese army, and lay minefields in the direction of the Japanese army's advance. After the Japanese army retreats or passes by, he can then find a way to raise mines or

What can be done to eliminate the risk of common people hitting mines?

Therefore, behind Chen Shanhe, Wang Jiudao, Chen Kai and Ye Liumu, there are more than 200 people from the minelaying engineering brigade directly under the regiment. These more than 200 people are the most skilled in minelaying in the entire regiment, the fastest, most secure, and most powerful in minelaying.

The person who appeared in front of Chen Shanhe now was Zhang Fulin, the captain of the mine-laying engineer brigade. He was the captain who fought hard for the whole group's mine-laying competition.

"Zhang Fulin, the landmines we planted have been dug up by the Japanese engineering team.

Now, I ask you to use all the mine-laying methods you can think of to compete with the Japanese engineers!"

Zhang Fulin responded: "Yes, let's go out and challenge the Japanese with their technical skills!"

Zhang Fulin is the kind of person who is ruthless and doesn't talk much. Now all the minelaying methods of the mine-laying engineering brigade, in addition to the mother-and-son mines taught by Chen Shanhe, true and false mines, rolling stone mines, and even the bullet mine concept, they have also developed their own

There are many strange methods of laying mines.

Under the transformation of the data panel that has been upgraded to the rank of second lieutenant by the system, Chen Shanhe's physical fitness, strength and senses are already extraordinary. He dare not boast that he can crack all the mines laid by the mine-laying engineer brigade.

Therefore, Chen Shanhe did not think there would be any difficulties in this duel between the minelaying engineer brigade directly under the regiment and the Japanese engineer unit?

After all, one is the one who proposes the question, and the other is the one who solves the question.

One is a guard against thieves for a thousand days, and the other is a thief for a thousand days.

The initiative always lies with the person making the move.

"Contact the political commissar and ask if the people in the nearby villages have been resettled and transferred.

This time the Japanese army was a division, unlike last time when there was only one brigade.

Moreover, the Fourth Brigade did not request the air force to accompany them last time. Now the Japanese 58th Division has already had three reconnaissance planes fly over.

So what follows is no longer a petty fight like last time, but a life-and-death fight with a clear picture.

All the people in the village must move to the rear, and then we can use and expand those tunnels.

We must be prepared to fight the Japanese 58th Division for a long time!"

"Yes, let's go and notify you now!"

Chen Kai, watching the Japanese engineers carefully clearing mines through the telescope, felt a little itchy in his heart.

"Captain, how can you watch them clearing mines like this?

How about letting the artillery battalion shoot him?"

Chen Shanhe glanced at him: "Chen Kai, you don't look like a scholar at all. Hold on, you can fight the battle, but not now!"

Think about it, if we bomb one Japanese soldier now, how many people can we hit?

Look at the Japanese troops, there is a person every 10 meters, and there is a person every 10 meters, they are all lined up so that they can no longer be seen.

Even if a landmine with a 100-pound charge explodes, it can kill at most two Japanese soldiers!

Do you know that this business is a loss?

Li Yunlong, the old leader of the new regiment, was now taken to the headquarters to feed horses. He said something that I think is very reasonable.

You can't fight a war and get poorer, you can't throw your belongings into the house without hearing any sound.

As soon as the gunfire rings out, something must be brought back!

But your shot can get the most out of you. If you are accurate, you can kill a little devil with one shot!

Can a little devil's life be exchanged for a cannonball? How much does a cannonball cost, and how much does a little devil cost?

You are still a scholar, can you settle accounts?

That’s not how wars are fought!”

When Chen Shanhe said this, Chen Kai felt it made sense. Looking at the position of the Japanese troops and the gaps between them, one shot could really kill at most one or two Japanese troops.

So if you think about it this way, one cannonball exchanges for two little devils, and sometimes you can't hit both of them. Isn't that a loss?

There is really no reason to do a losing business.

After all, the Second Independent Regiment can produce and sell on its own so far, except for landmines.

“But the Japanese army came in so arrogantly, we can’t just lay mines and let them clear them, right?

The mines will always be used up, and the depth will always be bulldozed.

Without depth, even if we have tunnels, we cannot face a Japanese division face to face!"

Wang Jiudao smiled and told him: "Battle Commander Chen, your artillery battalion and brother Liu Mu's hunting team will be able to show their full potential in the future.

Who is our group leader!

Chen Shanhe, Chen Shanhe who never suffers in a war!

The Japanese army directly used one division to prepare to overwhelm others. Have you ever seen the Japanese army use such a posture to deal with the Jinsui Army and any unit of the Central Army?

They usually use less to fight more!

No one looks down on it.

But today, a division was used against our regiment.
