Chapter 611: Challenge
Gently picking open the dirt, the mysterious bomb buried in the soil finally revealed a little clue.
Wooden handle!
Sure enough, it was a grenade.
Solemnly gently cut the wire, making sure that the grenade, which I don't know if it was still effective, would not detonate.
Then use a small shovel to lift off the surrounding dirt little by little.
It was the delicate work of threading the embroidery needle.
Solemnity is like digging up a priceless treasure, careful not to touch the body of a grenade.
In addition to the fear of collision, there is another point that must be considered.
That is, the explosives or fire caps that have been buried in the ground for many years have long been exposed due to the age, and will not undergo rapid chemical changes when exposed to fresh air.
This situation has been taught in theory classes.
Dig it out, and within a few seconds the projectile will snort, or expand, and then explode violently.
This is not something without precedent.
I didn't dig it, and I was thinking in my heart, don't blow up the grenade on the dog's day! Don't you blow up......
He's already figured it out.
If you dig up and find smoke, immediately turn around and run, and then pounce on the ground and hold your head for protection.
As for whether it will hurt or not, it's up to God.
Shrapnel doesn't have long eyes, no one knows how it can fly, all you can do is follow the basic tactical movements you have learned to complete self-protection.
When the rust-stained bullet body was slowly revealed, the solemn eyes were round little by little.
This is no ordinary grenade.
Solemnity only needed to glance at the oval iron head to know that this thing was not an ordinary Type 67 wooden-handled grenade.
This is a perverted thing with the full name of the Type 67 weighted grenade.
How is it different from regular bullets?
The simplest, the biggest difference is not only the appearance, but also the interior. The normal Type 67 grenade with a wooden handle is a 38-gram TNT charge, and this thing is a 60-gram TNT charge.
In other words, with nearly half of the charge, the power will naturally rise.
Fortunately, there was no one nearby, otherwise according to the rules, if you find something abnormal, you must report it immediately, especially this heavy grenade.
"Report! Discover a heavy grenade! ”
Solemnly in accordance with the rules, shouted the report.
Then proceed with demining.
Weighted grenades?
With this solemn report, everyone's hearts hung again.
Not to mention anything else, just saying that in case of an explosion, even if you solemnly wear protective clothing, protective helmets, masks, etc., your two hands will definitely be gone, and whether you can survive depends on luck.
Even if the suit can stop the shrapnel, it can't stop the shock wave.
The explosion impact vibration has the remarkable characteristics of high peak, short holding time, and wide frequency band. The first peak wave is characterized by rapid attenuation oscillation, with a super positive pressure wave appearing first, 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.
Solemnly half-kneeling on the ground, the heavy grenade that had been exposed for the most part was less than 50 centimeters from his handsome face.
At such a close distance, it was really unpleasant to stare at such a grenade that could easily tear itself to pieces.
Because you don't know if the rusty old object in front of you will suddenly blow you to pieces in the next moment.
Solemnity knows the power of this grenade.
To give an interesting example, the main gun of a tank has a muzzle velocity of 1,700 meters per second and a maximum chamber pressure of 700 Mpa under a charge charge weighing several kilograms. But when a shell is fired, the barrel does not blow off.
However, in many cases, if a soldier captures an enemy artillery position and wants to withdraw immediately, and wants to destroy the barrel before leaving, he can choose to throw a heavy grenade into the barrel, so that the explosion can destroy the barrel.
Why?
Why can a mine, with a few tens of grams of explosives, make the main gun scrapped or even directly destroy the tank?
In fact, the question of the difference between gunpowder and explosives is involved here. Many people think that gunpowder explodes in the chamber of the gun, but it is actually burning, but unlike the kind of combustion in life, the burning speed of military propellant is very fast, and it will increase with the increase of the pressure of the surrounding gas, so that when it burns in the chamber, the speed of gas production will be very fast, and it will look like an explosion. And the explosives of the grenade are real explosions, 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 the human body can be fatally injured by a shock wave overpressure greater than 0.1Mpa without any protection.
5GPA……
When I think of this parameter, I feel a buzzing feeling in my head.
He looked at it for a while and saw that the weighted grenade, which had been exposed to the air, had not changed.
There was no smoke......
There was no snort......
There was no liquid oozing or anything like that......
Very good, a great omen!
Only then did he relax and slowly lie down.
He should see more carefully, more clearly, and not allow for mistakes.
Now, he's going to take the Grim Reaper's gift out of the dirt and see if he can remove its fire cap.
"Why did it take so long?"
Even Han Zixuan, who had been staring intently at the minefield from a distance, had a hint of impetuousness flashing in his heart.
"He's on his feet!" Zhang Zhiang suddenly pointed to the minefield and said loudly: "It's done!" ”
Sure enough, in the eyes of everyone, solemnly slowly got up from the ground, first squatting, coming over for a while, then slowly standing up, and then picking up the mine detector and slowly probing around.
After a few minutes, he solemnly raised his hand and shouted: "Report! All the deceitful mines have been cleared! ”
As soon as the words fell, a tidal wave of applause rang out all around.
"Well done! Stately! ”
"Solemn! Attaboy! ”
This is the most moving voice that has been solemnly lived for twenty years and has ever heard.
solemnly took off the helmet, and the sweat that fell in an instant was like a bottle of water poured on someone's head, falling down with a bang.
The sweat all over his body has already soaked the camouflage uniform.
There were two rows of mines on the ground, and at the bottom was a heavily weighted Type 67 grenade with a wooden handle, a third of which had rotted.
"Substitution!"
Lian Yue waved his hand, he couldn't afford to delay time.
The second group of minesweepers immediately buckled their helmets and stepped into the minefield without hesitation.
Back in the shade of the tree, he sat down on the ground and threw his helmet aside.
Su Huikai handed over the kettle, solemnly grabbed it, took two sips, and then leaned against the trunk of the tree and gasped.
"Isn't the thorn irritating?" Su Hui asked.
solemnly lifted the corners of his mouth and smiled: "Stimulus." ”
"Is it painful?" Su Huikai asked again.
Nodding solemnly: "Happy!" ”
Han Zixuan came out from the side, looked at the solemnity on the ground with his hands twisted, and asked, "Is it fun to be a special soldier?" ”
Zhuang Zhuang suddenly laughed: "It's fun! It's so much fun! Hard! ”
————————————————————————
The Type 67 weighted grenade, it is estimated that the veterans who have participated in the round battle have played, and many soldiers who have not participated in it are estimated that they have not seen it, and the deminers who have gone out of the minefield.
When the author went to the munitions warehouse to move ammunition, he saw some of these ballast goods in a corner, and asked the volunteers in charge of the warehouse at that time, saying that it was a weighted grenade that could be used to blow up tank tracks.
This kind of thing is very powerful, about this kind of grenade, it has been on the news recently, as for what the situation is, it's not good to say it here, let's talk about it in the group.
