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

​​

Wooden handle!

​​

Sure enough, it was a grenade.

​​

He solemnly and gently cut the wire to ensure that this grenade, which is still ineffective, would not detonate.

​​

Then use a small shovel to lift the surrounding soil a little bit.

​​

It was the delicate work of threading the needle.

​​

Zhuang Yan is like digging for a valuable treasure, being careful not to touch the body of a grenade.

​​

In addition to the fear of collision, the damaged projectile must also be considered.

​​

That is, the explosives or flash caps that have been buried in the ground for many years have been exposed for a long time. Will they undergo rapid chemical changes when exposed to fresh air?

​​

This situation has been taught in theory classes.

​​

I dug it out, and within a few seconds, the projectile smoked, or expanded, and then exploded violently.

​​

This is not something without precedent.

​​

Without digging, Zhuang Yan was thinking in his heart, don't blow up Shiri's grenade! don't fry...

​​

He has already thought about it.

​​

If you find smoke coming out of digging, turn around and run immediately, then jump to the ground and hold your head for protection.

​​

As for whether it will be hurt or not, it is up to God.

​​

Shrapnel doesn't have long eyes, and no one knows how it will fly. All he can do is follow the basic tactics he has learned to protect himself.

​​

When the rust-stained projectile slowly revealed, the solemn eyes rounded up a little.

​​

This is no ordinary grenade.

​​

Zhuang Yan only had to look at the oval iron head to know that this thing was not an ordinary Type 67 wooden handle grenade.

​​

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

​​

How is it different from ordinary bullets?

​​

The simplest, the biggest difference is not only the appearance, but also the internal upgrade. Ordinary Type 67 wooden handle grenade is 38 grams of TNT charge, this thing is 60 grams of TNT charge.

​​

In other words, with nearly half of the charge, the power will naturally rise.

​​

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

​​

"Report! Found a heavy grenade!"

​​

Solemnly obeyed the rules and called for a report.

​​

Then continue to clear mines.

​​

Weighted grenade?

​​

With this solemn report, everyone's hearts were suspended again.

​​

Not to mention anything else, just say that in case of an explosion, even if you are solemnly wearing protective clothing, protective helmets, face masks, etc., your two hands will definitely be gone, and whether a person can survive or not depends on luck.

​​

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

​​

The explosion shock vibration has the remarkable characteristics of high peak value, short duration and wide frequency band. It is mainly characterized by the rapid attenuation and oscillation of the first peak wave, and a super positive pressure wave first appears, followed by a negative pressure wave.

​​

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

​​

Solemnly kneeled on the ground, the weighted grenade with most of it exposed was less than 50 centimeters away from his handsome face.

​​

At such a close distance, staring at such a grenade that can easily tear oneself into pieces is really unpleasant.

​​

Because you don't know if the rusty old object in front of you will suddenly explode and blow you into pieces in the next moment.

​​

Solemn knows the power of this grenade.

​​

As an interesting example, when the main gun of the tank is loaded with a propellant that weighs several kilograms, the initial velocity of the shell can reach 1700 meters per second, and the maximum chamber pressure can reach 700Mpa. But when the shell is fired, the barrel doesn't blow up.

​​

However, in many cases, if a soldier has captured the enemy's artillery position and has to withdraw immediately, and wants to destroy the gun barrel before leaving, he can choose to throw a heavier grenade into the gun barrel, so that the explosion can destroy the gun barrel.

​​

why?

​​

Why can a grenade field of dozens of grams of explosives make the main gun scrapped or even destroy the tank directly?

​​

In fact, this involves the difference between gunpowder and explosives. Many people think that gunpowder explodes in the barrel, but actually burns, but unlike the kind of burning in life, military propellant burns very fast, and it will increase with the increase of the surrounding gas pressure, so that in the When burning in the chamber, the gas is produced very fast, and it looks 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?

​​

Some data show that without any protection, the human body will be fatally injured by shock wave overpressure greater than 0.1Mpa.

​​

5GPA...

​​

Thinking of this parameter solemnly, there is a buzzing feeling in my head.

​​

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

​​

no smoke...

​​

no chi chi sound...

​​

There was no liquid seeping out either...

​​

Very good, great omen!

​​

Only then did he feel relieved and lay down slowly.

​​

He wants to see more carefully, more clearly, and not to lose.

​​

Now, he was going to take this Death God's gift out of the soil and see if he could take off its flash cap.

​​

"Why so long?"

​​

Even Han Zizuo, who had been staring at the minefield from a distance, had a flash of impetuousness in his heart.

​​

"He stood up!" Zhang Zhiang suddenly pointed at the minefield and said loudly, "It's done!"

​​

Sure enough, in the eyes of everyone, Zhuang Yan slowly got up from the ground, first squatted, came over for a while, then slowly stood up, then picked up the mine detector and slowly probed around.

​​

After a few minutes, Majestic raised his hand and shouted, "Report! All the booby traps have been cleared!"

​​

As soon as he finished speaking, there was a tidal wave of applause from all around.

​​

"Good job! Solemn!"

​​

"Solemn! Good job!"

​​

This is the most moving voice I have ever heard after living solemnly for twenty years.

​​

Zhuang Yan took off his helmet, and the sweat that fell instantly fell down like a bottle of water being drenched on his head.

​​

The sweat all over his body had already soaked his camouflage clothes.

​​

There are two rows of mines on the ground, and the bottom one is a heavy-duty 67-type wooden handle grenade~lightnovelpub.net~ One-third of the wooden handle has rotted.

​​

"Substitution!"

​​

When Lian Yue waved his hand, he couldn't waste time.

​​

The second group of minesweepers immediately buckled their helmets and stepped into the minefield without hesitation.

​​

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

​​

Su Huikai handed over the water bottle, grabbed it solemnly, took two sips, and then leaned against the tree trunk to pant.

​​

"Aren't the thorns irritating?" Su Hui asked.

​​

Zhuang Yan raised the corners of his mouth and smiled: "Exciting."

​​

"Does it hurt?" Su Huikai asked again.

​​

Nodding solemnly: "Happy!"

​​

Han Zizheng emerged from the side, clasped his hands, looked at the solemn figure on the ground, and asked, "Is it fun to be a special forces soldier?"

​​

Zhuang Yan suddenly burst out laughing: "It's fun! It's so fun! It's life-threatening!"

​​

The Type 67 weighted grenade, it is estimated that the veterans who participated in the round battle have played it, and many soldiers who have not participated have probably never seen it, and the deminers who have left the minefield.

​​

The author, Jun, saw some such ballasted goods in a corner when he was still going to the military warehouse to carry ammunition. At that time, he asked the volunteers in charge of the warehouse and said that it was a weighted grenade that could be used to blow up tank tracks.

​​

This kind of thing is very powerful. There has been news about this kind of grenade recently. As for the situation, it's hard to talk about it here. Let's talk about it in the group.
