Gently lifted the soil, the mysterious bomb buried in the soil finally revealed a little clue.

Wooden handle!

It's indeed a grenade.

Solemnly clamp the wire and break the wire to ensure that this grenade, which is unknown whether it is still effective, will not detonate.

Then use a small spatula to lift the surrounding soil bit by bit.

That is the meticulous work of threading an embroidery needle.

The solemnity is like digging a priceless treasure, and I am careful not to touch the grenade's bullet body without a single moment.

In addition to fearing collisions, a broken bullet body must also be considered.

That is, the explosives or fire hats buried underground for many years have been exposed because of the long time. Will there be rapid chemical changes when encountering fresh air?

This situation has been taught in theory classes.

Dig it out, the bullet body squirted out smoke or expanded within a few seconds, and then exploded violently.

This is not a precedent.

Without digging it up, Zhuang Yan was muttering in her heart, don’t blow up the grenade! Don’t blow up...

He had already thought about it.

If you dig it out and find smoke, you will turn around and run, then jump to the ground and hold your head to protect you.

As for whether you will be injured, it depends on God.

The shrapnel does not have eyes, and no one knows how it will fly. All they can do is to complete self-protection according to the basic tactics you have learned.

When the rusty bullet body slowly appeared, the solemn eyes became rounder little by little.

This is not an ordinary grenade.

Zhuangyan only needs to take a look at the oval iron head and know that this thing is not an ordinary 67-type wooden handle grenade.

This is a perverted thing with the full name of the Type 67 weighted grenade.

What's the difference between it and a normal bullet?

The simplest thing is, the biggest difference is not only the appearance, but also the interior has been upgraded. The ordinary 67-type wooden handle grenade is 38 grams of TNT charge, and this thing is 60 grams of TNT charge.

In other words, with nearly half of the charges, the power naturally increases.

Fortunately, there is no one nearby, otherwise, according to the rules, abnormal situations must be reported immediately, especially this kind of aggravated grenade.

"Report! A heavy grenade was found!"

Zhuangyan shouted a report according to the rules.

Then continue to clear the mines.

Heavier grenade?

With this solemn report, everyone's hearts hang up again.

Not to mention anything else, if you just say that it will explode, even if you are solemnly wearing protective clothing, protective helmets, masks, etc., your hands will definitely be gone. Whether a person can survive depends on luck.

Even if the protective suit can hold the shrapnel, it cannot stop the shock wave.

Explosion shock vibration has significant characteristics such as high peak value, short-term holding, and wide band. The main characteristics are that the first peak wave is rapidly attenuated and oscillated. First, a super strong positive pressure wave appears, and then followed by a negative pressure wave.

If the positive pressure wave exceeds the protective value of the protective suit, it will completely shatter. To put it bluntly, in the face of a powerful explosion, the protective suit is just a piece of paper.

Sorrow half-kneeled on the ground, the heavy grenade that had been exposed was less than 50 cm away from his handsome face.

At such a close distance, I felt really uncomfortable staring at such a grenade that could easily tear myself into pieces.

Because you don’t know if the rusty old object in front of you will suddenly exert its might and blow you into pieces in the next moment.

Zhuangyan knows the power of this grenade.

To give an interesting example, under the loading capacity of the main tank of the tank weighs a few kilograms, the initial velocity of the shell reaches 1,700 meters per second, and the maximum chamber pressure can reach 700mpa. However, when the shell is fired, the barrel will not explode.

But in many cases, if a soldier captures the enemy's artillery position, he has to withdraw immediately. Before leaving, he wants to destroy the artillery barrel, so that the explosion can destroy the artillery barrel.

Why?

Why can a grenade of only a few dozen grams of explosives be scrapped or even directly destroy the tank?

In fact, here comes the issue of the difference between gunpowder and explosives. Many people think that gunpowder explodes in the barrel, but it is actually burning, but unlike the kind of combustion in life, the combustion speed of military launchers is very fast and will increase with the increase of the pressure of surrounding gas. In this way, when burning in the chamber, the gas production speed will be very fast, looking like an explosion. The explosive of the grenade is a real explosion, and the maximum explosion pressure can reach 5gpa.

What is the concept of 5gpa?

1gpa=1000mpa…

And what kind of impact can the human body withstand?

Data show that without any protection, the human body will suffer from overpressure of shock waves greater than 0.1mpa, which will cause fatal injuries.

5gpa...

Zhuang Yan thought of this parameter and felt a buzzing feeling in her head.

He looked for a while and found that the aggravated grenade that had been exposed to the air had not changed.

No smoking...

No sound of hissing...

No liquid leaking out...

Very good, a great auspicious sign!

Only then did he feel relieved and slowly lie down.

He must look more carefully and clearly, and not be misunderstood.

Now, he will take this gift of death out of the soil and see if he can remove its fire hat.

"Why did it take so long?"

Even Han Zixiu, who had been staring at the minefield in the distance, had a hint of impetuousness flashed in his heart.

"He stood up!" Zhang Zhiang suddenly pointed at the minefield and shouted: "It's done!"

Sure enough, in everyone's eyes, he slowly got up from the ground solemnly, first squatted, came over for a while before slowly standing up, then picked up the mine detector and slowly detecting around him.

After a few minutes, solemnly raised his hand and shouted: "Report! All the thunders have been cleared!"

As soon as the words finished, there was a tide of applause around.

"Good! Solemn!"

"Soerful! Good!"

This is the most moving voice that Zhuangyan has lived for twenty years and has heard.

Zhuangyan took off her helmet, and the sweat that fell instantly seemed to be poured on a bottle of water by someone's head, falling down.

The sweat all over my body had already soaked my camouflage uniform.

There were two rows of mines on the ground, and at the bottom was a heavyweight 67-type wooden handle grenade, one-third of the wooden handle had rotted.

"Substitution!"

Lian Yue waved his hand and could not waste his time.

The second batch of minesweepers immediately put on their helmets and stepped into the minefield without hesitation.

Back under the shade of the tree, he sat solemnly on the ground and threw his helmet aside.

Su Huikai handed the kettle, grabbed it solemnly, took a few sips, and then leaned against the tree trunk to breathe.

"Is the thorn irritating?" Su Hui asked.

Solemn lifted the corners of his mouth and smiled: "Stimulating."

"Is it painful?" Su Huikai asked again.

Solemnly nodded: "Happy!"

Han Zixiu came out from the side, looked at the solemnity on the ground with his hands, and asked, "Is it fun to be a special forces soldier?"

Zhuang Yan suddenly laughed: "It's fun! It's so fun! It's life-threatening!"

—————————————————————

The Type 67 Heavy Grenade, I guess the veterans who participated in the rotation battle have played it, and many soldiers who have not participated in it have probably never seen them, and they have left the mine clearance field.

When the author Jun was going to the military warehouse to move ammunition, he saw some of these warehouse-pressing goods in a corner. At that time, he asked the volunteer soldiers in charge of the warehouse and said that it was a heavier grenade that could be used to blow up tank tracks.
