Others show their swords, I show my missiles!

As various villages and towns were liberated one after another, these villages and towns were connected together.

The area reaching the headquarters in the north, Xiangyuan in the south, Taihang Mountain in the east, and Xiadian in the west formed the safest liberated area.

Then it developed northward and reached Yushe and Liaoxian counties.

However, Yushe and Wuxiang have not yet been recovered.

At the same time, Brigadier Chen was not idle either. All the surrounding strongholds from Xiyang to Liao County have been eradicated.

People's organizations were gradually established in various villages and towns.

The Independent Brigade and the 386th Brigade were connected together, guarding the headquarters in the middle.

There are no Japs or yellow-shoe troops in the liberated areas, and even the ruffians and bullies have been purged.

Refugees from other areas have also moved to this area.

The next plan is to continue to develop westward on the basis of continuing to strengthen public security management and focusing on resuming production.

Strive to be integrated with the Yanzhou headquarters. Block the enemy's passage south from Jin Province.

After discussion, the Yanzhou headquarters believes that our army has now passed the stage of strategic stalemate and entered the stage of strategic counterattack.

While the soldiers were cleaning up the remaining enemies in the villages and towns, Li Yunlong and Zhao Gang were working together on programming to solve the problem of coordinated operations among the air defense battalions.

After more than ten days of unremitting efforts and joint research. Finally, a beggar’s version of the air defense joint combat command system was created.

Of course, this thing will be scorned by programmers in future generations.

The entire system doesn't even have a firewall. Any little hacker can hack the system.

But at this time, the devils obviously did not have the talent in this area.

Historically, this method of storing compiled programs in computer memory and executing them sequentially was proposed by John von Neumann, a native of Russia.

Before this, in order to complete a certain task, computers usually completed the program by operating a series of switches or changing the wiring system. That is, only data was stored in the memory, not the program.

After he proposed the stored program principle in 1946, he not only established the basic structure of computers, but also created a new era of programming.

Because this is not history. Although personal computers only appeared recently, computers in various high-tech equipment have already been used.

After the joint air defense combat system was compiled, a network system was established.

If the air defense battalion wants to change locations, the optical fiber must be unplugged first.

After the maneuver is in place, the optical fiber can be connected to the command system.

After this system was put into operation, coordinated operations were formed among the air defense battalions.

If eight enemy planes come at the same time, you can command this battalion to attack these four enemy planes; that battalion can attack the other four enemy planes.

Of course, the software system created by two knives cannot be described as "powerful". It's passable at best.

If Sysenterm had not provided some source code, the two independent brigade executives would still be immersed in studying the introduction to programming!

After testing, dozens of drones were used as target drones. Each battalion attacks 4 aircraft at the same time, and 5 battalions can eventually attack about 15 aircraft.

In any case, it cannot achieve the effect of multiplying 4 and 5 to equal 20.

There will always be repetition.

But this is much better than each battalion fighting on its own!

Zhang Dabiao was burying his head in reading the map at this time, summarizing the information reported from all sides.

"Brigadier Commander, the villages on the western edge of the liberated area are too difficult to defend.

Take Hanbei Village as an example. Every time our people leave, the Japanese come.

The devils are here to kill people, set fires, and steal things. If we don't compete with our main force, the village militiamen are far from being a match for the Japanese.

We can only see the Japanese coming, so we organize the villagers to go into the mountains.

As for the Japanese, they will run away as soon as they finish the destruction. Never hesitate.

Especially like our previous guerrilla tactics.

By the time our main force comes back, the Japanese have already disappeared! I can only help put out the fire and deliver some food to the villagers. "

Zhang Dabiao said.

Zhao Gang said: "It's such a coincidence every time. Someone must have tipped off the information. It shows that the cleanup of the remnants of traitors is not thorough enough."

Li Yunlong waved his hand and said: "Old Zhao, the remnants of the traitors will not be cleared away in a while.

Our troops must be reasonable and not be like the Japanese who would rather kill a thousand by mistake than let one go. "

Zhang Dabiao continued: "It is true that as the brigade commander said, sometimes we suspected that he was a traitor. But the villagers did not identify him and we had no evidence. Then we could only let him go. At most, he would not be allowed to hold any position. .

If he secretly reports to the Japanese, as long as we can't find any evidence, there won't be much we can do. "

Li Yunlong poured a cup of hot water and said while warming his hands:

"I said, why do you two always worry about this traitor? The point is how to defend the liberated areas!

The traitor thing is slowly being figured out.

I often walk by the river, how can I not wet my shoes?

He has done a lot of tipping off, and there are always clues left behind.

He did many bad things, so the people and militia organizations tried to find ways to get rid of him.

There is no need for us to take action.

As regular troops, we must do what regular troops should do.

Let me tell you, we can't always think about defense. I always want to prevent the Japanese from causing trouble.

In my dictionary, there is no such word as defense!

When the devil comes, kill him; when he escapes, he will take over his lair. Does it still dare to come? "

Zhang Dabiao felt a little enlightened: "Yes! This is called 'offensive defense'!

Just like what the brigade commander often said before: We don’t know anything but attack!

Only offense can turn passivity into initiative. Annihilate the enemy's vitality to the maximum extent.

Kill a few batches of them and they won't dare to come out.

There is no need for us to put so many people on the border of the liberated area to defend. "

Li Yunlong nodded in approval.

"That's right!"

In the early morning of the next day, a small group of Japanese soldiers attacked a village south of Hanbei Village called Donggou Village.

Compared with Hanbei Village, Donggou Village is much smaller. There are only a few households.

A few days ago, Hanbei Village had been completely destroyed by the Japanese. This time they arrived at Donggou Village.

When they heard someone beating the gong, the villagers did not hesitate, took some food and fled into the mountains.

After the Japanese came, they moved whatever they had as usual, but in fact there was nothing left to move.

Just set a fire and prepare to retreat.

Not far to the west is a river. The water is very shallow. At this time, it is mainly a frozen mud.

Although the river is shallow, it is very wide, and this is an open area.

As long as you cross this river, there is a highway in front of you. You can reach Yushe in the north and Wuxiang in the south.

Just as the Japanese entered the river beach and wanted to cross the river as soon as possible, several "boom, boom, boom" sounds came from nowhere.

Then a sound of "chirp, chirp" came from the sky.

It's like a band playing, working together very well.

Experienced Japanese soldiers heard it right away: it was the sound of falling mortar shells, and it was also a kind of urging sound.

This melody is always beautiful.
