Others show their swords, I show my missiles!

"Awesome! Lao Xiao!" Wang Qingrui, leader of the Sixth Regiment, praised.

"From now on, don't call your regiment an air defense regiment, just call it a missile regiment! We can fight both in the sky and on the ground!"

"Hahahaha, that's exactly what I meant!

Some time ago, when you were all training, I had nothing to do, and there weren't that many target drones to practice flying, so I kept wondering whether I could use anti-aircraft missiles to hit ground targets.

Unexpectedly, the first time I actually tried it, the effect was really good! "Xiao Zhanwu said without any humility.

Brigadier Li said:

"Humility will not make people progress. If you are humble on the outside but proud in your heart, you will find a way out for future failures and will only stop you from moving forward;

Only by showing off can you make progress! When you show off, others will praise you. If you want others to praise you in the future, you will continue to make progress. "

It seems that this statement is true!

Without Xiao Zhanwu's expressive character, he would not have proposed using surface-to-air missiles to attack tanks, and his talents would have been buried.

Later, Xiao Zhanwu summarized the experience of using anti-aircraft missiles against tanks and handed it over to Li Yunlong.

After Li Yunlong looked at it, he felt as if he had discovered a new world.

"Hit tanks with anti-aircraft missiles? You are really a fucking talent!"

It's not that Xiao Zhanwu's method is so clever. After all, the anti-aircraft missile is just a cameo to hit ground targets, and it is not professional.

The key is the talent of Xiao Zhanwu.

You know, the independent brigade's drones can originally carry professional cruise missiles.

In fact, it is a stealth sub-drone, divided into low-speed version and high-speed version.

The high-speed version functions close to a missile and is used in suicide attacks;

The low-speed version has many functions, such as reconnaissance. After all, it flies too high and the reconnaissance is not careful; but if it flies low, it is vulnerable to attack. So the mother aircraft was at high altitude and a low-speed daughter aircraft was released to conduct reconnaissance at an altitude of 1000 meters.

In addition to reconnaissance, suicide attacks can also be launched. If it can be used to its effectiveness, you will not be afraid of the Japanese 33rd Division's underground tactics.

At that time, this small plane can plunge into the hole and detonate a thermobaric bomb.

And the backslope can be completely ignored, it can attack from behind the Japs.

In addition to reconnaissance and suicide attacks, it can also perform many tasks, such as spraying pesticides, increasing rainfall, extinguishing fires, etc.

In addition to drones that can carry missiles, heavy infantry fighting vehicles can also carry missiles.

But this missile is an anti-tank missile, not a cruise missile with a range of hundreds to thousands of kilometers.

It uses fiber optic guidance, so even if the Japanese tank hides behind a hillside, it will be useless. It can fly upward first, cross the obstacle, and then attack the tank from the top.

Realize the attack effect of hitting a cow across a mountain.

Although it does not use armor-piercing projectiles, but armor-piercing projectiles.

Here we will first popularize the knowledge about armor-piercing, armor-breaking and armor-breaking bullets.

When armor first appeared, it was ordinary homogeneous armor, which was a layer of steel plates.

The thickness is not very thick, about 5 to 20 mm.

Even large-caliber rifles can penetrate such armor.

So there have been anti-tank guns.

As the thickness of the armor became thicker and thicker, by the end of World War II, it was basically unable to penetrate any tank, and it withdrew from the stage of history.

Armor-piercing bullets are the oldest anti-armor bullets. They have been developing since the birth of armor. They are the most effective and traditional anti-armor bullets.

Early armor-piercing bullets had ordinary solid warheads, and at most they had improved warhead shapes and added hoods.

As the armor becomes thicker and thicker, the kinetic energy required by armor-piercing projectiles becomes larger and larger. In order to increase the kinetic energy, the caliber needs to be increased.

Kinetic energy is positively related to speed and mass. In layman's terms, this "quality" is "weight".

In order to increase speed, the artillery barrel is also lengthened.

Anti-tank guns are generally high-pressure, long-barreled, direct-aiming cannons.

As the caliber increases, the diameter of the armor-piercing projectile increases.

But there is another concept in physics: "pressure".

Pressure is used to express the effect of pressure. The greater the pressure, the more obvious the effect of pressure.

Increasing the pressure while keeping the stress area constant, or decreasing the stress area while keeping the pressure constant, can increase the pressure.

As for large-diameter armor-piercing projectiles, the force-bearing area is larger. Although the kinetic energy increases and the pressure increases, the pressure is smaller, which affects the armor-piercing effect.

So the armor-piercing bullets evolved into sub-caliber armor-piercing bullets: a smaller high-density armor-piercing warhead is installed in the warhead to reduce the armor-piercing area, thus increasing the armor-piercing capability.

The further evolution of sub-caliber armor-piercing bullets is the discarding sabot bullet, and the ultimate form of the armor-piercing bullet: the fin-stabilized discarding sabot bullet.

Armor-piercing bullets have evolved into tail-stabilized discarding sabots, which have basically reached the limit of the kinetic energy of gunpowder-driven barrel weapons for armor-piercing.

The armor-piercing ability of an armor-piercing projectile depends on the kinetic energy of the armor-piercing projectile as well as the impact area and sustained ability. Its performance is that the speed is fast enough, the bullet core is heavy enough, and the bullet core is long enough.

In order to increase the weight of the bullet core, it is necessary to use high-density materials to make the bullet core.

Nowadays, tungsten alloy or uranium alloy is generally used.

Relatively speaking, uranium alloys are heavier and more effective, but there is a certain risk of radiation contamination.

The armor-piercing ability of armor-piercing projectiles has always been excellent. After penetrating the armor, metal fragments will be scattered everywhere in the vehicle body, similar to the shrapnel from an exploding artillery shell, killing people and devices in the vehicle.

With the upgrade of armor technology, even in the 21s of the [-]st century, armor-piercing bullets are still the most difficult type of bullet to defend against.

But armor-piercing bullets have some natural flaws:

It requires a launching device to give it sufficient kinetic energy. In order to achieve this purpose, the size and weight of the launching device cannot be easily reduced.

The material requirements for the launch device are also very high.

For example, it can be fired from a tank gun, but not from a shoulder-fired rocket launcher.

Armor-piercing bullets have different characteristics from armor-piercing bullets.

The principle of armor-piercing bullets does not rely on pure kinetic energy to penetrate armor, but uses the principle of shaped energy reaction.

The concentrated energy effect is often called the "Monroe effect".

The Monroe effect was discovered by an Russian named "Monroe" who conducted an explosive experiment in 1888:

If you dig a conical hole in a cylindrical explosive and then ignite the explosive, there will be a strong explosive airflow in the direction of the conical hole, which can concentrate the energy of the explosive explosion.

In this way, although the charge is reduced, the explosive effect in a specific direction is stronger.

Therefore, the exterior of the explosive is designed to be a concave hollow. When the explosive explodes, the main energy is concentrated in the direction of the hollow charge, and the metal part of this part will form a high-temperature and high-speed jet.

This kind of warhead is also called a hollow charge shaped warhead.

We generally call this kind of bullet an armor-piercing bullet.

The advantage of the armor-piercing projectile is that the source of its kinetic energy is the explosive power of the armor-breaking projectile's own explosives, rather than the kinetic energy given by the launcher. This puts very low requirements on the launcher.

As long as this bomb can be thrown near the target, the rest is the projectile's own business.

Including anti-tank grenades, rocket launchers, recoilless guns, and anti-tank missiles, all of which use armor-piercing projectiles.

But armor-piercing bullets are not good at everything, otherwise there would be no need to use armor-piercing bullets.

Its armor-piercing effect is not as good as armor-piercing bullets. In addition, its damage effect after penetrating armor is not as good as armor-piercing bullets. That is to say, the aftereffect is insufficient.

If it penetrates the armor but does not damage the important equipment and personnel in the car, then the car just has a hole for more ventilation. How to open it?

In addition, it has high requirements on the timing of the missile explosion. If the vehicle body is equipped with a metal grid, it may jam or detonate the missile in advance.

Thereby reducing its armor-piercing effect.

Explosive reactive armor is also effective against armor-piercing projectiles. This kind of armor will automatically explode, deflecting the metal jet and rendering it useless.

Furthermore, armor-piercing projectiles tend not to fly very fast and are relatively easy to prevent.

To deal with armor, there are basically these two devices.

There used to be armor-breaking rounds, but now they are only used against buildings.

Because of the emergence of composite armor, it is particularly effective against armor-breaking projectiles, and armor-breaking projectiles are immediately ineffective.

Armor-piercing and armor-breaking bullets existed until the 21s and [-]s.

So, with such a useful weapon, why not use it?

The reason is that no one knows how to use it!

At present, no one except Li Yunlong can play with the missiles on the drone.

Now we have finally found a talent who may be qualified for this job, and that is Xiao Zhanwu!
