Chapter 4619: Vintage weapon

No wonder Lin Rui felt dissatisfied. Although this weapon is an anti-tank weapon, it is actually outdated. There are many anti-tank weapons today, but there are very few anti-tank grenades. Except for countries like Russia, few people are obsessed with producing such things.
Because the short board of the anti-tank grenade is too obvious, the first is the distance. Its range is limited by the throwing distance of the user. It is only 15-30 meters. It requires soldiers with strong arms to throw it far, which is obviously shorter than that of modern anti-tank rocket launchers. .
An infantryman carried an anti-tank grenade and had to rush to a position more than 20 meters away from the tank to use it. In the fierce battle, it is estimated that he was shot in the middle. And this thing is not as good as a rocket launcher.
But this thing is not without value. First of all, the price of anti-tank grenade is cheap, much cheaper than the rocket launcher. The production can also be simple, nothing more than a large charge, relying on the form of a metal jet to penetrate the armor. The production process is simple, and the cost is naturally cheap.
The second is that it is much smaller than a rocket launcher, and it will not emit sound, smoke or fire when thrown, so as long as it is used properly, the infantry can evacuate in time with this, and it is difficult to detect.
Therefore, many such anti-tank weapons can still be found in many hot spots in the world today. China has also imitated it, but the Chinese version is called the anti-3 anti-tank grenade.
Lin Rui wanted to scold someone with this thing, but he looked at the sausage again and endured it. Lin Rui also knew that he was afraid that Anmore's army would not be able to defend him before, so he ordered some anti-tank weapons to be allocated to them. Otherwise, the sausage would not carry this old antique with him.
"Do you know how to use it?" Lin Rui asked Sausage.
"Probably know a little." Sausage nodded.
"Forget it, let me tell you again. This thing is a bit complicated, there are three insurances." Lin Rui shook his head, "Remember, when you use it, hold the handle with your hand and use the other one. The hand pulled out the external safety pin to release the first insurance, and then dropped the bomb towards the target.
After the grenade is ejected from the hand, the bottom cover spring at the bottom of the handle pushes the bottom cover and the safety plate backwards, and at the same time the stable umbrella cord tied to the bottom cover pulls the safety rod out. After the grenade pops out of the hand for a certain distance, the bumper releases the long-distance insurance ball, which is equivalent to a missed insurance, preventing accidental misses from causing the grenade to explode in advance. At this time, the second insurance is also released.
When the safety lever is separated from the handle, the push spring inside the handle pushes out the stabilizer umbrella, while the fuse and the bottom cover pull the stabilizer umbrella apart to form a stable tail, which ensures the stability of the grenade flight and the correct hit attitude. When the grenade finally hits the target, because the bumper has been separated from the projectile, the firing pin seat safety steel ball is no longer restricted by the bumper, so that the limitation on the firing pin seat is released and the third insurance is released.
At this time, the heavy hammer behind the firing needle seat slams the firing needle seat, forcing the firing needle to strike the acupuncture detonator forward, detonating the charged charge, and generating a high-speed metal jet. The armor penetration depth can reach 170 mm and the penetration thickness can reach 500. Mm concrete fortifications. "
"Okay, I see." Sausage nodded.
"We each take one. Remember that when we count to three, we throw it out at the same time, don't throw it straight. Use the parabola to hit the top of the tank with a high parabola. If not, use a low parabola to hit the side armor of the tank. After this thing is thrown out, a stable umbrella will be opened. The high-throwing of the top of the armor is the most effective, but it is also the most difficult. Do you know?" Lin Rui whispered, tapping the sausage.
"Damn, to be honest, I have played with explosives for so long, and this is the first time I have used this." Sausage shook his head nervously.
Lin Rui gestured to him, and then the two leaned out at the same time and threw the RKG-3 anti-tank grenade in their hands.
"Boom, boom..." The mountain shook for a while, the explosion sounded deafening, and the body of the BMP-1 infantry fighting vehicle was shining brightly and scattered sparks. Lin Rui's grenade hit the side armor of the infantry fighting vehicle, but Sausage was lucky, hitting a high throw, and the grenade exploded directly on the top of the BMP-1 infantry fighting vehicle.
The BMP-1 infantry fighting vehicle is itself a famous little crispy. Weak armor that can penetrate even large-caliber machine guns. Naturally, the anti-tank grenade could not be defended, and the armor was blown through on the spot.
This kind of anti-tank grenade, in fact, uses a similar principle to other armor-piercing ammunition, using shaped charges. The shell of the armor-breaking attack part is wrapped in a cylindrically shaped high-explosive material. A tapered pit was dug at the top of the column, and a lining made of copper and other metals was pressed on the pit wall.
The blast came from behind the cone, and the shock wave hit the metal lining at a speed of 8000 m/s, concentrated on the apex of the cone. The entire liner is then compressed toward the bottom of the cone, and the pressure is concentrated on the center line of the cone. The compressed metal linings are stacked together and then pushed out from the center of the cone bottom.
Due to the huge pressure generated by the blasting shock wave, the metal is sprayed out in a straight line at a speed of 8000 m/s to 9000 m/s. Although it is still a solid metal, its powerful kinetic energy makes it move like a liquid. When the lining is piled up under pressure, the mass that needs to be pushed by the shock wave gradually increases, and the kinetic energy obtained per unit mass also gradually decreases.
The direct result is that the metal speed of the initial injection is above 8000 m/s, while the subsequent injection gradually decreases to around 2000 m/s. The difference in speed causes the ejected metal to form a column, which is called a metal jet. When the metal jet hits the armor, its powerful kinetic energy forces the materials that make up the armor plate to flow around in a liquid state, giving way to a tunnel.
But at the same time, the head of the jet continues to spread around, and the jet continues to be consumed. If the jet cannot penetrate the armor when it is completely consumed, the armor wins. However, if the jet penetrates the armor before it is completely consumed, it will carry debris formed during the impact and penetration into the vehicle at high speed, killing people and destroying equipment.
The armor of the BMP-1 infantry fighting vehicle was weak and was instantly penetrated by two anti-tank grenades. The metal jet penetrated the car body, and even shot a cross at some locations. Not only did it blow through a number of driving and crew members, but it also destroyed the internal equipment. The body of the car was full of smoke and fire.
"Cover!" Lin Rui shouted, leaping out. He squatted forward while shooting along the way.
"Tutu, tutu..." Sausage also withstood the of the rifle, followed Lin Rui, and fired at the enemy. The cover shooting of the mercenaries immediately followed, and several general-purpose machine guns used for fire cover fired in clusters, and their shells were thrown away.
Lin Rui leaped forward and rolled, falling sharply to the ground. With his superb marksmanship and excellent response, he quickly approached the destroyed BMP-1 infantry fighting vehicle. Using this chariot as a huge shelter, Lin Rui squatted and fired quickly at the remaining enemies.
Under his cover, other mercenaries also began to rush forward, killing the remaining ten enemies on the road where the chariot was burning.
