Speaking of the king of land warfare in later generations, tanks are always the most powerful. Thick armor, fierce firepower, and flexible mobility, the trenches and cannon military theory of the First World War were trampled on.

Let us look back on history and look at the day on September 15, 1916, when tanks ruled the battlefield in the world. On that day, British and German troops were fighting on a large scale on the Somme River, both sides held their positions, and neither of them broke through the other's positions. The Somme River was full of swamps, and shells exploded around the river bank from time to time, and waves of mud were thrown into the sky, and thick smoke enveloped the river bank.

Suddenly, a huge rumbling sound came from the British position. A group of monsters like steel bunkers rushed out of the position and crushed the German army. When the German soldiers saw these monsters, they shot at them desperately and bombarded them with cannons, but the monster was invulnerable to swords and guns, and they also used small-caliber machine artillery on both sides to shoot the German army. While fighting back, they still rumbled forward. These steel monsters easily entered the depth of the German position, posing a great threat to the German army.

This huge mobile steel fortress is the "land cruiser" that Britain first invented and put into the battlefield - a tank! It weighs 28 tons and requires 8 crew members. It has a prism-shaped side. It has two cannons with a diameter of 75mm and several machine guns on both sides. It uses overhead heavy metal tracks and is suspended rigidly, with a maximum speed of 6 kilometers per hour. At that time, there were no communication equipment, and several carrier pigeons were carried with the vehicle. If necessary, they would rely on carrier pigeons to contact us.

The first appearance of the tank was overwhelmed by its unparalleled powerful performance. The war model built on trenches, machine guns, artillery and barbed wire mesh was overwhelmed by human wars on land. The 59 tanks used to participate in the war that day were transported to the front line under extremely secret circumstances. Among them, 10 tanks remained in the rear as a "reserve team" due to mechanical failures. 32 of the remaining tanks drove to the starting point of the battle. During the offensive battle, 5 were trapped in the mud and unable to extricate themselves. More than 10 tanks also failed to reach the predetermined area due to various reasons. In the end, only 9 tanks rushed into the German position and advanced 13 kilometers in depth, with a success rate of only 15%.

However, the spectacular and majestic scenes of tank attack left a deep impression on the German army, causing chaos in the German positions that could not be attacked in the past. Tanks allowed the British army to easily break through the German defense line and greatly encouraged the morale of the British army. From then on, the value of tanks on the battlefield was recognized by military strategists, and countries studied it one after another, and soon the tanks became the main weapon of land warfare.

Strictly speaking, tanks were not invented, but modified with tractors. The inventor of the tank was a British military reporter named Swinton. During the interview on the front line, he saw with his own eyes that the British and French coalition forces were repelled by the closely defended Germans. Many soldiers fell in pools of blood, with heavy casualties. So he began to think about how good it would be if the tractor was put on a thick steel armor coat so that it would not be afraid of guns and bullets, but could attack the enemy's positions. So he suggested putting the "Holter" tractor on iron armor and becoming a new type of combat chariot to the battlefield.

This suggestion was quickly adopted by the military. Soon, the world's first tank was produced by a British water cabinet factory. At that time, in order to keep it confidential, when transporting the tanks to the front line, all tank packaging boxes were marked as "water cabinet". The English name of "water cabinet" is tank, which is pronounced as tanks. Therefore, the name of the tank was called "open" and was widely used by various countries.

Less than two months after the tank appeared on the Somme battlefield, the German side also began to try to produce this powerful weapon as the equipment of the army. In November 1916, the German General Staff proposed the technical requirements for German tanks and commissioned the 7th Transportation Office to formulate a tank design plan, which was named the a7v combat tank. In January 1917, engineer Joseph Wolmer designed and designed and completed in January 1917.

Due to the war needs and the use of ready-made "Holt" tractor chassis, the design work progressed quite quickly. In the summer of 1917, a prototype car was made and a prototype car was started. Subsequently, the German side could not wait to demand the production of a7V tank. In this way, although there were still many problems with the prototype car, the first A7V tank was still rushing to produce in October 1917. It was originally planned to build 100 vehicles, but due to the shortage of steel and the priority of the overall industrial of the empire, Germany only produced 22 vehicles. A7V produced a total of 22 models, including prototype cars, test cars, and improved models, 17 were put into the battlefield, and the rest were made into a7V-r battlefield conveyor vehicles.

For China, the current tank technology is not a technical problem that is difficult to overcome. Zhong Yang has a small agricultural machinery production plant under his command. With a slight modification, he can produce old-fashioned tanks with the "Holt" tractor turret as the core. Compared with the great powers, the only fatal flaw is insufficient production capacity. The production capacity of 30 aircraft per quarter is really unavailable.

The main reason is that Zhong Yang is really not satisfied with the current tanks. Whether it is armor, vitality, or the frighteningly high failure rate, it is difficult for Zhong Yang to accept. In carrying out technical cooperation with Germany in this regard, Zhong Yang naturally showed a certain sincerity, including hollow armor-breaking bombs, a single weapon known as the "tank killer".

Armor-breaking bombs, also known as hollow charge armor-breaking bombs, are shells that penetrate armor with metal jets formed by the explosion of energy-concentrating charges. They are also called energy-concentrating charge armor-breaking bombs, which are one of the main types of anti-tanks. They are mainly used for tank guns, anti-tank guns, resilient guns, etc. They are used to damage armor targets and concrete fortifications such as tanks. After the jets penetrate the armor, they use remaining jets, armor shatters and detonation products to damage personnel and equipment.

The main purpose of the use of armor-breaking bombs is to target the threats brought by tanks. Its main feature is that the armor is pierced by the energy of the charger itself, so it is not limited by the initial velocity and firing distance. It is a type of bomb with great development potential. However, its charge is very knowledgeable, because hollow charge armor-breaking bombs mainly rely on making the charge into hollow cylindrical columns with conical holes, and adding a metal cover to the surface of the conical holes. In this way, when the explosion occurs, it will form a metal energy jet with great speed, temperature and pressure, that is, the "energy-gathering effect", destroying the armor. On the contrary, if the charge is solid, the purpose of armor-breaking cannot be achieved.

In fact, in the 19th century, some people discovered the energy-generating effect with the concave columns. However, Zhong Yang also successfully lining the concave pot with a thin metal cover when the concave pot was lined with a thin metal cover, which greatly enhanced the armor-breaking power generated by the charge, resulting in the energy-generating effect being more widely used.

And as the research continues to deepen and the increasingly high requirements put forward by Zhong Yang, the Mechanical Service II type has summarized better armor-breaking bomb technology through a lot of experiments: by continuously improving the explosion height of armor-breaking bombs, we study ways to improve the penetration ability of armor-breaking bombs under large explosions. We use double-cone medicine covers and precision charges to increase the ability of the mother-in-law, increase the hit probability of long-distance armor-breaking bombs, and also develop armor-breaking bombs that attack long-distance tank groups.

Of course, the armor-piercing bomb i-type exchanged with the Germans for tank technology and heavy machine gun technology is just a relatively superficial type of armor-piercing bomb technology in Zhong Yang. Although the two sides are working together, who doesn’t have their own ulterior motives and keep one hand? This is the Military Technology Research Institute, not the Red Cross Society that is generous, and Zhong Yang is not the Tian Khan who likes to send his technology to the public. Naturally, he keeps his own hand in everything.

With the development of a smart factory, this kind of individual weaponization of energy-concentrating armor-piercing bombs was finally realized. This weapon has an unparalleled advantage in targeting tanks and most fortifications. This is also the only military technology that Zhong Yang can now trade with Kasa and others.

Under the cover of the agricultural machinery production plant, Zhong Yang secretly built a tractor production plant. It was on the surface to provide power for the mechanized agricultural production, but in fact it was with the German military research department to secretly develop new tanks. The two sides had both cooperation and differences. Zhong Yang had allocated one of the secret bases specifically to these German researchers for use, and he only sent some young apprentices.

However, Zhong Yang's own research department is in an underground base in another mountainous area. Although the two places are not far apart, it would be difficult for people who are not interested to discover it. The technology brought by the Germans has been read by Zhong Yang and recorded it in the computer system inside the smart factory. The mechanical servant II type also began to analyze these technical knowledge, and I believe that the results will come soon.
