The machine gun sent the cavalry to a dead end, and in order to resist the machine gun, the tank was invented, the tank can become the protector of the infantry, it is by virtue of its own armor, the tank in order to block the artillery more fierce than the machine gun, it can only thicken its own armor, and the artillery, in order to block the opponent's steel torrent forward, and constantly improve their ability to strike armor, the conflict between the spear and the shield, has always been in the history of the development of the world's armored forces. Pen % fun % Pavilion www.biquge.info≦≧

However, in this process, the spear has always had an advantage, that is, the armor lags behind the ammunition. For example, an armor-piercing projectile can penetrate homogeneous steel armor about 5 to 7 times the diameter of its warhead. That is, a 100-mm armor-piercing projectile can penetrate steel armor 500 to 700 mm thick.

In the West from the 50s to the 70s, it was basically still at the level of using traditional single cast steel, such as the German Leopard 1, the frontal armor was only less than 100 mm thick, and the American M60 was only about 150 mm thick, and at that time, the way to deal with the opponent's shells was to maneuver. Before the 70s, the West believed that mobility was higher than protection among the three major elements of the tank, because the fire control system at that time was still very primitive and had limited ability to capture and track targets at high speeds. ≦≧, the engine and transmission system of the West are already very mature, but after the development of electronic technology and optical technology, the fire control system of the tank began to develop greatly, and it began to have a high hit rate against mobile targets in motion.

Countries all over the world have begun to study composite armor, the so-called composite armor, which is a sandwich biscuit, in the middle of the steel plate, with a layer of special material. The USSR was the first to use composite armor on the T-64. However, the most successful of these is the United Kingdom, an old capitalist country.

In 76, Britain successfully developed the "Chobham" armor, which is a composite armor with a multi-layer structure. The outer and inner layers are hard and tough high-quality alloy steel armor, and the middle layer is thick, blocky ceramic armor, which plays the main role of bullet resistance. According to British sources, the ability of the "Chobham" armor to deal with armor-piercing shells is three times that of the original rolled homogeneous steel armor.

In later generations, Britain's armor technology has always been a leader. Even the German Leopard 2 tank. After a lot of twists and turns, the British Chobham was finally chosen on the Leopard 2A4, but. Later, it was found that it was shrunk by the British.

The composite armor of various countries is an absolute secret. ≦≧ this is about their basic national defense, therefore, how thick are the layers of "Chobham" armor? What is the composition of each layer of armor? What are the know-how in the structure and processing of the armor? These British would never reveal it, as this would give the hostile country an opportunity to dismantle their own armor.

In later generations, in addition to the depleted uranium armor of the United States, I am afraid that Chobham armor is famous.

However, in the present, Chobham armor has only passed through the first generation. It is defective, the main reason is that the ceramic material in the middle will produce cracks under high-speed impact, and the crack propagation speed is about several hundred meters per second, while the propagation speed of the metal jet of armor-piercing projectile is as high as 7000 meters per second, and the generation of cracks will not affect its strength. Moreover, due to the constraints of the inner and outer layers of steel plates. As well as the curing effect of the intermediate binder, so that the ceramic powder formed by impact has no "escape channel", and the metal jet "against the dry" plays a role in counteracting the metal jet. As a result of the combined effect of the two aspects, ceramic materials have become masters in dealing with armor-piercing projectiles and missiles, but against low-speed kinetic projectiles such as tail shell-off stabilized armor-piercing projectiles. The effect is very poor.

So, when the first generation of Chobham armor began to be produced on the British Challenger 1. ≦≧ British Armored Forces Research Institute, a new research and development was started, considering how to deal with the armor-piercing projectiles that have become the new mainstream, and finally, this year, a breakthrough was made.

The British, having already found a way to deal with armor-piercing shells, that is, cut it off!

The new Chobham armor consists of 6 layers with two outer layers of steel plates, two middle layers of advanced ceramic plates, and two inner layers of steel plates. The ceramic plates in the middle are divided into pieces and placed in a slightly larger outer sandwich envelope with rubber strips on the sides. When the tank is hit by an armor-piercing projectile, the outer two layers of steel plates first slow down the speed of the bullet core, and when the core touches the two layers of ceramic plates in the middle, the two layers of ceramic plates slide back and forth left and right at the same time after the collision, so that the direction of movement of the bullet core changes, and even the core can be cut into several sections, the kinetic energy of the damaged bullet core is sharply reduced, and the residual energy is quickly absorbed by the inner two layers of steel armor plates.

This is just a principle, but also needs a complex theoretical model, a large amount of experimental data, and the crystallization of their entire research institute's hard work is in those thick reports.

Because those have not yet been reported, they have not yet become the focus of the military's protection, such as the initial Chobham armor, the Soviets tried their best to get it, but the luck of the Messiah Bureau was too good. ≦≧

This is related to the prototype of the composite armor of the Challenger 2, the main force of the British armored forces for the next twenty years, and the new theory of the Chobham 2 armor that can withstand the attack of armor-piercing shells, all the secrets, on this dull night, fell into the hands of two foreigners.

After getting the information, the two of them were very excited, and immediately left here in the way they had just come.

Thomson, who was outside, had already looked at his watch several times, and finally saw the two of them get out of the dormitory building again, and immediately started the vehicle, carried the two of them, and left here.

"Where are we going now?" Thomson asked.

"To the South Cross Street of the Town." Hidali said.

"And what about my pay?" Thomson asked.

"The reward will be given to you when it's on Crossstreet. ≦≧," Hidali said. One after another, Thomson has been given nearly 50,000 pounds, and this time, such a big thing has been done, Thomson asked for a million pounds, and Hildaly also agreed.

Another Messih Bureau vehicle was already waiting at Crossstreet, and got out of the car first, and from the car he picked up a heavy suitcase, which was the reward for Thomson.

"These are for you." Hidali said.

Thomson was so pleased to see the full pounds of the suitcase that he took the suitcase, put it on the co-pilot, and watched the two leave, get into the car, and he also began to return.

The car didn't go, and Hitali kept looking into the mirror while counting the numbers in his mouth.

When I counted from ten to zero, I saw that the car that had disappeared to the end of the street suddenly exploded, and the fire lit up the street entrance.

Underneath those counterfeit coins was a bomb that was enough to say goodbye to drugs once and for all.

"We have to leave the UK as soon as possible, the embassy has made you new passports, and tonight, we will fly to France and then back to Iraq."

…………

Sultan took Qusay's hand affectionately and said, "President Qusay, you are our big hero in the Middle East, but no one has taken care of your daily life yet, it must be inconvenient, right?" ”

"I've always had Gasal take care of you." "It's very convenient," Qusay said. ”

Don't know what you mean? Or pretending to be confused? Prince Sultan continued: "President Qusay, I am dozens of years older than you, and I can be regarded as your senior. ”

Wait, and Kusai finally understood: "But I'm just turning twenty now." He really wanted to go on to say that early marriage is illegal.

"What's wrong with twenty? When I was 20 years old, I already had two children, wasn't Bandar born when I was 20 years old? Now as an ambassador in the United States. Qusay, your marriage should not be delayed any longer, but unfortunately this time, President Saddam left too early, but those of us who are elders will not look at you until now that you are still alone, you matter, the two of us will help you, choose a beautiful and virtuous one in our Saudi royal family as your wife, what do you think? Prince Sultan said.

Qusay complained a little in his heart, these two old guys, each with more than a dozen wives, still want to take care of themselves, because until now, he really hasn't considered the issue of marriage, it seems that it is still far away, what he thinks about in his heart is how to develop Iraq, how to make the Middle East unified and strong, before the collapse of the Soviet Union, Iraq needs to have the capital to confront the United States, every day, he is racing against time.

"yes, Cusay, what do you think of us Faisal?" King Fahd asked.

Hearing this, Sarah, who had already changed her clothes and was walking towards the palace, just walked to the door, heard the king's question inside, and immediately stopped her steps, she really thought right, this time she called herself back, is it to discuss the marriage with Qusay? Thinking of his infatuation with Cusay, remembering that he has done so much, from a princess who doesn't have to worry about anything, to the manager of a business empire who is now busy every day, he needs to make so much money at all, how the world's science and technology develops, and it has nothing to do with him, let alone trying to hold the stocks of those military-backed companies, all of this is for Cusay, since she first saw Cusay, she knew that she could never forget this man, at that time in France, this man pressed himself underneath, Help herself block the danger, her heart belongs to this man.

Looking at her body, she took a shower for an hour, soaked in hot water, completely washed away the fatigue on her body, and then, wore a gorgeous Arab robe, all green, embroidered with some gold thread flowers, wearing a red scarf on her head, and quietly painted her toenails red with "Hana", although she preferred Western-style clothes, however, she felt that it was more in line with her identity to wear this traditional dress.
