The Japanese occupied the surface near him, which Shang Xi knew clearly, but the Japanese did not dare to easily approach these pits that were squatting to replenish mines, and he also knew it clearly.

And this is the time when the mine-replenishers are most dangerous, and the main defense is for the Japanese to throw grenades into the pit where they are.

So all they can do is throw grenades outside.

Because the porcelain grenades were too cheap, when the paratrooper school took over this position, the porcelain grenades dropped by the 264th Brigade actually reached several hundred baskets.

Yes, that's right, these things are in baskets just like potatoes. In a rattan basket, a layer of clay porcelain grenades and a layer of straw can be stacked at will.

As a result, in the pits of the front-line mine-replenishers, there were a stock of 100 or 10 at random.

According to Shang Hee's instructions, when the devils appeared near the pit of their mine-replenishers, their task was to throw grenades outside the pit, and the requirement was to pull the fire and count "one, two, three" before throwing it, and not too far.

Then in the pit where all the mine replenishers still existed, grenades continued to rise. Just a slight deviation from the crater they are in, and then it will explode in the air.

No one wanted to die under the bullets or grenades of the Japanese, and all the surviving mine-replenishers were very diligent in throwing grenades outside.

As a result, a large group of Japanese soldiers who opened several skirmish lines could not advance, and the machine guns of the other side did not agree to retreat. Just huddled in craters stupidly, desperately wondering what to do.

Zhang Sixing, who has a bad taste, calls this tactic formed by relying on almost infinite earthen porcelain grenades "geyser". After all, every few moments, a grenade rises from a hole in the ground or an air explosion.

It's a bit like a geyser.

The way to deal with this tactic is to hide for a few tens of meters and throw a grenade into it.

It's a pity that the ordinary infantry of the Japanese, grenades are not mandatory equipment. Second, if they wanted to throw grenades, they had to ask the almost countless snipers and sharpshooters if they agreed.

At this time, it was only three hundred meters away from the main position, which was the best distance for rifle engagement.

Especially as the Japanese attacking brigade was stopped by the "geyser" because of the forward, and several layers of straggler lines gradually coincided, suddenly a military horn sounded.

"Bugle, is the person going to charge back?"

Of course not, if the paratrooper school has already been established and the number of troops is sufficient...... If it is not necessary, Zhang Sixing will not charge back. He would rather organize the people who will definitely be killed and injured in the counter-charge, and play interspersed and raided.

"No, it's not the tune of the Charge, I've heard people mention it to me, and it doesn't seem to be like that."

As the Japanese soldiers huddled in the craters, crouched in the ground and shooting, hiding behind corpses, muttered to each other, they saw a strange scene on the battlefield.

The holes of the hateful "geysers" that sprayed grenades were all the same as they got back the cover of their pits and put them on top of the pits.

If you can see the inside of the hole, you will find that people like Shang Xi can only reluctantly burrow into the waist-deep horizontal hole at the bottom of the cave at this moment.

It's cold, it's really cold, the hateful little devil was driven into the water in front of you because of you, and I have to give you a few more grenades when I get out of it.

With the sound of "Peng Peng" being launched from the main position, round plates flew in the air. Under the horrified gaze of the Japanese, the gasoline cannons seemed to fall from the sky, constantly dropping patches of porcelain grenades.

The terrible gray-yellow smoke of the offensive tear gas eggs immediately filled the battlefield with the wind when those grenades exploded.

And then......

A moment later, a bugle sounded to a different tune. For Shang Xi, who was lying in the cold water, it was really not as if he had heard the Buddha name of the Bodhisattva who saved the suffering and saved the world.

The little devil of the dog grass, let Lao Tzu soak in cold water for so long, isn't this really making Lao Tzu fall into old illness.

While scolding in his heart, Shang Xi tried his best to dry the water on his clothes. As he twisted the water on his pants, he heard screams mixed with Japanese outside.

Danger suddenly caused him to throw the cold aside, and then gently pushed the cover open with the periscope, and he was amazed by what he saw outside.

As he opened a crack on his head, a spicy smell that became lighter but for Jiangnan people was almost tearful came to his nose.

Offensive ...... Offensive ...... By the way, what do those soldiers call this thing offensive tear gas?

But this egg is also so spicy that any southerner can eat it.

In fact, the gray-yellow dust on the battlefield had long been blown away by the wind at this moment, and Shang Xi only smelled a little "aftertaste".

But a brigade of devils outside is not so comfortable, who would have thought that the weapons that frequently appear in the night raids, in broad daylight, to these hateful fellows to throw them away, and throw hundreds of them at once, are their grenades so worthless.

It's really not worth much, except for the explosives and the flare, which are worth the money, and the rest is just two copper plates. Even offensive tear gas eggs are used much less explosives than other grenades.

The purpose of this weapon is to temporarily incapacitate people. According to the test, a normal person who has been subjected to offensive tear gas is unable to recover his basic mobility for at least ten minutes.

Shang Xi was not the only one who observed the embarrassing situation of the Japanese army outside from the periscope, and they lifted the cover of their pits one after another.

Go out and fight hard, these people who are wet don't dare. They were also not armed, not even a bayonet.

However, there are many grenades in the potholes, so they are placed in the most convenient places.

One by one, grenades flew out of the crater and landed among the nearby Japanese who were blinded by the chili pepper dust.

At this time, Gao Zhisong, who was far away from the main position, because his position had not yet been attacked, he still had a short time. However, he guessed in his heart that the Japanese, who had suffered such a big loss, should not attack the position of the paratrooper school again.

At this moment, he had two exclamations, one was that the defensive tactics of the paratrooper school were very simple and effective.

The people in the pits in front of them looked dangerous, but they were in fact fully protected by their own firepower. In this range, the opposing infantry is not only subject to the power of fire from weapons from the rear, but also the almost infinite threat of grenades.

And that "geyser"-style, constantly throwing out air-blown grenades, is really not an easy means to crack.

After all, there is more than one row of those potholes, and if you want to blow up the people in those potholes, you have to worry about the steel helmet mines behind. If that thing explodes, all the people standing within thirty meters will be extremely dangerous.

As for how to attack such a position, it is needless to say that the Guo army will have to be broken up under the attack the night before. Even if the Japanese army did not have tanks and armored vehicles, it would be very difficult to deal with light rifles, artillery, and aircraft. Then the devil must come at him.

Put down the binoculars and instruct his deputy brigade commander,

"Brigade Commander Liao, I think the devils are going to take care of us soon, get close to the soldiers, put the devils close and beat them with grenades."
