Another violent explosion came, right near Liu Mang's four people!

"Smack!"

"Smack!"

……

In just an instant, it blew up the sand and mud all over the sky, and then fell overwhelmingly on the heads of the four people, and several people were disgraced.

"Damn, this Africa is really in turmoil!"

Wiping the dust and mud off his face, Liu Mang scolded in a low voice.

"Isn't there a bullet with explosives in the warhead?" Tang Xinyi said curiously, although he is the director of the Game Office of the Southeast Military Region, he has really not studied this aspect.

Now listening to Liu Mang's popular science, a wave of interest suddenly rose in his heart.

"In the early design of gun shells, there was indeed a class of varieties with explosives in the warhead, called explosive shells. The structure of this kind of bullet designed by various countries is roughly the same, and it is generally used in aviation machine guns, usually with the dual effect of explosion / incendiary, and is used to indicate the impact point or shoot at thin-skinned flammable targets such as airships, balloons, and airplanes.

Among them, the more typical one is a kind of 303 caliber explosive bomb produced in the early stage of the United Kingdom, which is equipped with a copper tube inside the warhead, which contains a small amount of passivated nitroglycerin explosive, and the bottom of the tube is filled with yellow phosphorus or yellow phosphorus-based substances as an accelerant.

However, nitroglycerin is very unstable, so it is dangerous to store and use, and it is quickly phased out. Liu Mang briefly recalled the relevant information he had learned before he crossed over, and then after sorting it out in his mind, he also observed the surrounding situation before speaking again.

I was really frightened by the explosion of this bomb just now, if I was too involved, a mine exploded directly next to the four people, and I was afraid that the whole army would be wiped out directly.

Maybe he has the special ability that can be resurrected on the verge of death provided by the weed gene, but what about Tan Xiaolin, An Ran, and Tang Xinyi?

"By the time of World War II, explosive warheads were still widely used only on large-caliber machine gun shells, which generally had a separate fuse in the head and were similar in structure to a scaled artillery shell.

However, only explosive incendiary bombs are retained as auxiliary special ammunition in ordinary gun shells, typical of which are Germany's 7.92 mm B type B explosive incendiary bomb and Russia's 7.62 mm 3D incendiary bomb.

The structure of the two warheads is basically the same, the front part of the warhead is equipped with an incendiary agent, the middle part is equipped with a firing pin and a needle cap to ignite the incendiary agent, and the tail part is sealed with a lead pad.

When this kind of warhead collides with a soft target such as the human body, it also has the possibility of exploding and burning, and the lethal effect at this time is not lower than that of a dummy bomb. ”

"Awesome, I really can't tell you're a rookie!" Tang Xinyi was amazed by Liu Mang's words, she had never heard such a detailed explanation.

Including, Tan Xiaolin, and Enron are the same.

Never heard such a detailed explanation!

"If you are a special soldier of other troops, instead of the devil training under our Fire Phoenix for nearly half a month, if anyone says that you are a new soldier, I, Tan Xiaolin, will be the first to be anxious with him!"

At this moment, Tan Xiaolin also sighed thoughtfully.

"But now it seems that even if you are a rookie egg who has just entered the special forces this month, you can't be said to be a rookie egg now, but an old fritter!"

"That's a lot of work!" An Ran suddenly pinched Liu Mang's ears and rotated them 180 degrees directly.

"I used to pretend to be in front of me, pretending not to know anything, but now when I come out with a beautiful young lady to perform a mission, I know everything?"

"It hurts!"

"It hurts!"

?……

In just an instant, Liu Mang shouted one after another: "I didn't pretend, you yourself didn't ask me about this, could I take the initiative to tell you, I know this, I know that, I know everything, there is nothing I don't know, isn't this treating myself as a fool?" ”

Enron: "......"

"Isn't it, sister??" Seeing that An Ran was silent, Liu Mang hurriedly spoke again.

"Or do you want me to treat you like a fool?"

Enron: "......"

Tan Xiaolin: "......"

Tang Xinyi: "......"

"What's that mercury bullet you just talked about?"

After a few seconds of silence, An Ran's face suddenly turned a little red, and he asked hotly, now desperately wanting to divert the current embarrassing problem.

The source of this statement comes from "The End of the Jackal" translated and published by the People's Publishing House in February 1981. The book was written by the British political thriller F. Forsyth, whose work is known for its intellectual depth and clever detailing. Liu Mang said while opening several major visions and genetic skills to guard the port that is now under fire.

The book tells the fictional story of a professional assassin codenamed "The Jackal" who was hired to assassinate French President Charles de Gaulle. To accomplish the task, the "Jackal" himself designed a small sniper rifle that could be disassembled and hidden in a crutch, and equipped it with a "blaster" filled with mercury in the warhead.

The detailed description of the process of making the weapon and the bullets made a deep impression on all readers who read the book. The book had a great influence in the West, and was made into a movie of the same name in 1973, and it has been reprinted many times in China, so the "mercury bullet" is said. ”

"Is that real, or is it fake?" An Ran became curious, for this aspect of things, like Tang Xinyi, he has not studied much, and he is not very clear.

Now when I heard Liu Mang mention it, my curiosity was immediately aroused!

"Do you think it's true or not?"

Liu Mang asked rhetorically.

Suddenly, An Ran fell silent.

When the words reached Tan Xiaolin's mouth, Tang Xinyi also swallowed it back.

"Whew, mercury is poisonous, and at the same time has greater density and fluidity than lead, which can theoretically increase the power of dummy bullets. However, this design may seem feasible, but in fact it has little application value. After taking a deep breath, Liu Mang grabbed the gun and said while guarding.

The "mercury bullet" mentioned in the book was modified from a nickel-copper alloy armored, 22 Magnum rifle cartridge, and due to the limited size of the bullet, the mercury was placed by drilling holes in the longitudinal part of the bullet and then sealing it with molten lead.

Mercury is liquid at room temperature, and when heated, it will produce highly toxic mercury vapor, which can be poisoned by inhalation or skin contact.

Even at room temperature, mercury will slowly evaporate if not properly sealed, so the manufacture and use of such warheads poses a significant risk to the user itself. Another characteristic of mercury is that it can miscible with copper and other metals to form corresponding amalgam, which has high requirements for sealing conditions.

As far as the structure of the warhead itself is concerned, the "shell" consisting of a shell and a lead core must be thick enough to ensure that the mercury inside can withstand the high temperatures of the launch, and that it will not rupture prematurely due to strong centrifugal force to release mercury, which is difficult to meet in practice. ”

Speaking of this, Liu Mang's words paused, and then he said with a deeper voice: "The most critical point is that because the "shell" cannot be tightly combined with the liquid mercury inside, the "shell" rotates under the action of rifling......
