The Mulan team led the special forces team to report good luck to their superiors with a huge victory of two battles and no sacrifices. The news quickly spread to the island. It was a pity that the Japanese suffered too much to bear it. They actually withdrew early, causing the main force that was originally surrounded to wipe out their troops and returned in vain!

However, this is not a bad thing for the headquarters. After all, a lean camel is bigger than a horse. The Japanese really want to be trapped beasts. If they fight, a large number of anti-Japanese patriots will inevitably sacrifice, because the training gap between the two sides is there, and the Japanese army also has the support of armored trains and planes. If they really want to surround them, it will definitely be a bloody battle to kill one thousand enemies and hurt eight hundred themselves. You must know that this area is a plain. Once both sides encounter it, there will be no ambush and other tactics.

The Japanese army retreated in a hurry, one was because of huge losses in personnel, and the other was that the logistics base was attacked and could not continue to fight. Therefore, many things could not be taken away before they left, which made the Eighth Route Army soldiers on the island in vain.

Tents, wooden boats, various cold-resistant military blankets, etc., are usually treasures that they are unlucky. With them, they are not afraid of snow in the middle of winter. Of course, the Japanese set fire before leaving, but the autumn dew is too thick and there is very little gasoline. They scattered as soon as the smoke rose, leaving so many spoils.

Zhao Hu didn't have time to count these things. He was dragged and pulled by Professor Dai to the steel factory. Here, he saw an extremely flat steel plate.

"I said to Professor Dai, you pulled me here early in the morning to show me a piece of steel? I have seen a lot of this thing!"

"This is not ordinary steel plate!"

Professor Dai reached out and picked up and knocked. Zhao Hu found that there was nothing surprising except for the clear sound. He saw Old Dai's eyes shining and said, "Do you know what this is? Steel plate, high-strength stampable steel plate!"

"What? So, copper clad steel was created?"

"It's still one step away, but only by making the steel plate out first can you cover copper on it!"

Perhaps afraid that Zhao Hu would not understand the advantages of this steel, Lao Dai said proudly: "This is a treasure we have obtained after hundreds or thousands of experiments. The tensile strength is greater than 300, and the elongation is greater than 25 in both longitudinal and horizontal directions. It can definitely be used as a bullet!"

Although I don’t know if it was really used thousands of experiments or if it was a flash of inspiration, Zhao Hu knew that this kind of deep-drain high-quality carbon steel was definitely not easy to produce. Its plasticity and brittle impurities must not be higher than level 3. The addition of the two must not be higher than five. There must be no inclusions on the surface, shrinkage hole residues, internal cracks and skins, etc. Once there is one exceeding the standard, the bullets and shells produced may have hidden injuries. When used on weapons, they either explode or get stuck. It will kill people at critical moments. No wonder the Germans made this copper-clad steel early, but no country has spent so much energy to make it. It is because it is actually too troublesome and too troublesome!

When making ammunition shells, the best thing is naturally copper. This thing not only has a good self-lubricating effect, but also has good ductility, so it can easily break out of the desired shape. The key is that it can be reinstalled after use, and the end is the best choice for shell material.

But now the base is poor and even if there is some steel, it has to be used. Then the arsenal will let go of copper and pull all the people in the logistics department to buy copper coins. Besides, this copper has been lacking since ancient times, let alone used to make consumables. No wonder people say that when a cannon fires, it is not unreasonable.

Then, he thought of the reloaded bullets in the base area. This thing can solve the urgent problem in normal times. But on the battlefield, there is no time to pick up bullet shells. Sometimes the troops switch to fight, and there is no time or energy to clean the battlefield. This is only possible when every battle is won. What if it is a night battle? Once the bullet is stepped on and deformed, it has to be rebuilt, and it takes effort. Therefore, when the war has formed a scale, it is still realistic to rely on the continuous production of its own arsenal!

With steel shells, can we directly build paint bullets? That's even more impossible. Now he doesn't have the ability to create such high-strength pull-shell hooks. Moreover, when the bullet is fired in the gun chamber, it is exploded and expanded by gunpowder gas, and it will be tightly attached to the gun chamber. The copper shell is better, but due to self-lubricating, it can be easily pulled out, and the steel shell is miserable. Once it is pulled off, the round steel skin is left in the chamber, and the gun will be temporarily scrapped!

Since you want to make copper-clad steel eggshells, you have to consider bullets. After all, this is just a layer of copper skin on the outside of the steel shell. One is used to successfully remove the shell, and the other is to save a lot of copper materials. But after all, there is a layer of steel skin inside this thing, and if the bullet is not in good shape, it will not be pulled out either.

There is only one answer, that is, to make the bullet cone, with a large back and a small front, so that no matter how deformed the eggshell is, it can be easily pulled out. As for this kind of egg, it is even more familiar, that is m43 egg!

The total weight is 16.4 grams, the head weight is 7.91 grams, and the Bodan base fire is not made too much by himself. He knows any size clearly. But he is still a little hesitant. If he really wants to create it, the caliber of the enemy will be different from the enemy in the future. The method of fighting to support the war is no longer feasible.

But when I thought about it, I thought it would be better to make it. If a country does not have its own standard egg medicine, it will be controlled everywhere in the future. I haven’t seen that after decades, A San Ge has an aircraft carrier and can’t even build a small bullet?

Of course, with the production capacity of the island's arsenal, the new gun eggs currently produced may only be able to supply one regiment or one battalion with all their strength.

But Zhao Hu made up his mind that even if the output is small, he would build an eagle on the battlefield. This army would make the enemy frightened, and would be invincible. At the critical point of the war, sometimes a force of ten thousand people might not be as sharp and powerful as a battalion!

Not long after the report was launched, he received instructions from his superiors, agreeing to Comrade Zhao Hu to make every effort to build an elite battalion. The arsenal should fully support the establishment of this battalion in the best of its ability. At the same time, he also ordered Zhao Hu to do everything possible to build the most suitable weapon for this elite battalion and serve as a pilot for the entire army!

Well, Zhao Hu was demoted again and became a glorious battalion commander, and his subordinates could only lead four companies, but he did not regret it at all, because this battalion would be the starting point for our army's mechanization and the enemy's nightmare. So, what's the name of this battalion?

Eagles, wolves, fox hunting, no, they are called all of them. If you can’t think of it, it’s better not to think of it, just call it Jibuying. Anyway, after the enemy is afraid of being beaten, they will name it, and this name will always be in history!

The Mechanical Bus Battalion, Battalion Commander Zhao Hu, the First Company Commander Zhou Bing, the Second Company Commander Ruan Xiaoer, and the Third Company Commander Ruan Xiaowu, there is only half of the reconnaissance company, and it is still a burr. As for the Machine Cannon Company, Miss Yu snatched it away. In her words, Zhao Hu was born to build good cannons for his wife. If he couldn't make it, he would have to suffer in the future!
