If the hollow-charged grenades and grenades were not very eye-catching, then the anti-tank rocket launcher he conceived was definitely a good thing that was ahead of its time.

Due to contextual and definitional issues, later generations often confuse "rocket-propelled grenades" and "recoilless guns", which is not rigorous.

To put it simply, the launcher does not need to bear the pressure of the bore is a rocket-propelled grenade, which is commonly known as a bazooka; What needs to be subjected to bore pressure is a recoilless gun.

For example, the famous "Iron Fist" series in the late stage of the Great War, although people call it the Iron Fist bazooka, it is actually a recoilless gun in principle.

And the "tank killer" and "bazooka", because the ammunition has its own rocket engine and the launcher does not withstand the pressure of the chamber, so this is a real bazooka.

Considering the background of the times, and at the same time uncertain whether Da Ming could solve the technical problems of the bazooka rapid-ignition propellant, the weapon sketch drawn by Zhou Changfeng was essentially a recoilless gun.

But it doesn't matter what it's called, it doesn't hurt, anyway, calling it "Da Ming God Machine Beast Hunting Cannon" and "Bazooka" won't change its effectiveness.

In history, after the birth of the prototype of the "Iron Fist", Klein Iron Fist, there were successively improved versions such as Iron Fist 30, Iron Fist 60, Iron Fist 100, and even the last Iron Fist 250.

Unlike other disposable, throw-and-throw models, the Tekken 250 does not have a pre-loaded propellant inside the canister, but instead fits the propellant into the tail of the warhead and redesigns the launcher so that it can be reloaded.

After the war, the RPG-2 was born with simple modifications based on it, and the Chinese imitation was the Type 56 bazooka.

【Iron Fist Series】

Considering that the threat of tanks is not big enough to require infantry to have a bazooka, Zhou Changfeng chose a design idea that can be reloaded and used in a more economical way.

Based on the Iron Fist 60, he reduced the size of the warhead, and the charge was reduced to only 400g of TNT;

Changing the mask from a conical shape to a hemispherical shape that is easier to process but reduces the depth of armor piercing; The propellant is 80g of black powder;

There are two grips under the canister, and the sight above is a simple ruler, and the four holes correspond to four distances.

In this way, even if the medicine shield is made of cheap mild steel, the armor penetration depth can be about 100mm, and most armored targets can still be easily destroyed.

As for the range, he couldn't say for sure, after hesitating, he didn't design an expansion cavity for it, so the utilization efficiency of the black powder propellant was very low, and it was estimated that the maximum range was about 90m.

"Okay, if you really fight, at least you can enjoy the Sherman lighter!"

Zhou Changfeng was very satisfied with his work, and even confidently thought that the military industry of the Ming Dynasty could be put into production directly without making major changes, completely forgetting that he was actually just half a bucket of water.

Just when he was struggling to submit the work directly to the Ordnance Bureau or send it to the Yingtian Arsenal, a phone call came directly.

Zhou Changfeng didn't care at first, but he didn't expect that this call was actually from the Ministry of War.

The Ming Dynasty's Huitong Pavilion was special, not only responsible for receiving the tributary envoys of the vassal states, but also undertaking the task of delivering the Beijing Division.

Today's Daming Guild has been transformed into an organization similar to the Information Bureau of the Ministry of National Defense, responsible for receiving and organizing news work at home and abroad.

Now the embassy is calling to inform him that there will be a press conference tomorrow, and he must be there.

At this point, Zhou Changfeng suddenly remembered what the colonel said to him before leaving, who was in the garrison command at that time.

He actually doesn't want to deal with this kind of scene, although it seems that he can be in the limelight, but the pressure he needs to bear is not small, and the words, conversations, and behaviors on this occasion represent the image of the country.

The next day, in the morning.

If the spring and summer training uniforms of the square collar look a little rustic, then the summer clothes of the stand-up collar look much more energetic.

The main color is slightly lighter dark green, with arrow sleeves, collar, knee-length robe, leather belt around the waist, and short leather boots on the feet.

In order to prevent clothes from crumpling and pilling, in recent years, the Ming army has gradually switched to a blended fabric - composed of 70% cotton and 30% acetate, the latter is a new type of man-made fiber, and the Ming Dynasty was the first country to put it into mass production.

In addition to the circumference of the collar that made the circumference wind that was accustomed to Western-style open collars feel a little awkward before the crossing, the overall look is concise and generous, and the dark green color scheme is similar to the pine branch green he is familiar with.

As for the hat, he feels that in fact, the large-brimmed hat with this body should not be abrupt, and the hat he is wearing now seems to have a bit of a high center of gravity?

This is an improved military hat based on the cloud scarf of Zhongjing's crown uniform, which was historically designed by the Jiajing Emperor, and is now shorter and tougher at the corners, as a military hat to match the regular clothes.

After getting dressed neatly, Zhou Changfeng suddenly thought that he still had a knife?

As an honor that only ten people in each subject of Yingtian Martial Arts Academy can obtain, in addition to the silver-white pistol, there is also a delicate Yanling knife.

Ebony scabbard, sheath and sheath are decorated with shiny copper patterns. Different from the traditional Yanling knife, this knife is mostly straight, only the first fifth has a small arc bend, and it looks very tough.

Isn't this much stronger than what katana?

He walked out with a knife, and then drove straight to the military headquarters hall.

After arriving, I saw that the neighborhood was already full of cars, and all kinds of people were constantly entering the venue, at least half of them were foreign journalists.

Soon, he was led by two officials to a large room.

There were several officers and officials talking about something, and when they saw Zhou Changfeng coming, they stopped talking.

The leader was an old man who looked about sixty years old, and the whole person was very energetic and not angry.

Zhou Changfeng recognized him - Nan'an Hou Pang Lingqi, the commander of the First Division of the Praetorian Guard, and the commander of the garrison, this is a person who is not talented in military but works hard, and is talented in politics but does not work hard.

"Career circumference wind reports."

Pang Lingqi nodded with satisfaction and said, "Huang Tize used to brag about you from time to time, but now it seems that it is indeed real kung fu, and the fake trick will be revealed as soon as it goes into battle." ”

"It's just doing your job."

"Yes, not to be proud...... Okay, now you've seen this meeting, right? The press conference started at ten o'clock sharp, and the rain of bullets and bullets has been drilled, can you handle the scene later? ”

"Should... Yes. "Zhou Changfeng is indeed a little unconfident.

"Huh? Is there such a thing as 'should'? A line is a line. ”

"Report, you can handle it!"

Pang Lingqi bowed slightly, and reminded:

"But I have to give a few words, the factory said that some guys want to embarrass the court at today's press conference, and this aspect is a whirlpool, and the political matter cannot be explained in a few words."

"We've tried to find excuses to disqualify a few of them, but there are bound to be some that slip through the net, so you have to be careful that someone will try to make things difficult for you, you know?

"If you encounter it, you must respond to it on the spot, and if you feel that you can't resist it, ignore it and directly change the topic for others to ask. It is better to offend a gentleman than a villain! ”
