A courtyard house; Li Yunlong, a subordinate of the deputy director of Harbin Military Engineering I

Despite his thoughts, the legion commander still had to ask, "Can it work without a cannon barrel?"

In his mind, what kind of cannon is it if it doesn't have a barrel?

He stared at the bare shell, then looked at Zhang Renfeng, his expression clearly saying, "You kid, are you messing with me?"

Zhang Renfeng did not answer him, but instead explained, "The 107mm high-explosive fragmentation grenade uses a high-explosive fragmentation warhead combined with a rocket engine containing a fixed amount of propellant. It uses the principle of vortex to provide power to the shell, and increases the stability of the shell by spinning."

The destructive power of this shell is quite good. You might want to compare it to a 42-kilogram Katyusha shell.

"Stop comparing. This shell has the advantage later. We'll talk about that later. Let's just fire one more shot first."

After saying this, he squatted down, straightened the shell, and aimed at the distant tree with the simple markings on the cannon barrel.

what?

Before anyone could react, Zhang Renfeng had already connected the four batteries to the rocket's conductive cap and rear centering section.

He then retreated to Commander Chen's side.

He retreated decisively, but when he landed, he landed squarely on Commander Chen's foot.

Everyone was startled, especially Brigade Commander Chen, who had just looked at him with admiration. His expression suddenly turned ferocious. "Damn it, you stepped on my foot."

He grimaced, his cane thumped on the ground, and he gasped in pain.

Zhang Renfeng put his arm around his shoulder, "Bear with it!!"

His words were fierce, but the force in his arm carried a hint of reassurance, just like the fierce yet protective stance he had taken when covering his retreat in the Taihang Mountains.

Immediately afterwards, a few seconds later, an extremely powerful jet of air shot out from the tail of the cannonball on the rock, leaving a terrifying trail of flame.

The shells soared into the air with a piercing hum!

The legion commander stared wide-eyed at the flying shell. "No, is this right?"

He almost dropped the binoculars in his hand, quickly raising them to follow the trail of flames.

This was beyond his comprehension. Wasn't this far superior to the heartless cannon maker?

When Zhang the Explosives invented that thing during the Red Army period, he was still commanding battles on the front lines. Later, he heard that some troops had used it and caused chaos on the Japanese positions, but he didn't take it too seriously, thinking it was just a crude emergency method.

But this thing in front of him looked neat and orderly. When it was fired, the trajectory of the bullet was straight, leaving a white line. Its imposing presence was unlike any other cannon he had ever seen.

He remembered laughing at the kid back then, saying that the name "Atomic Cannon" was too grand.

"Hey, you guys should observe the trajectory of the shells with your binoculars before you speak," Zhang Renfeng reminded them, raising his own binoculars to look into the distance.

Only then did everyone snap out of their daze and pick up their binoculars.

The shell trailed a bright arc across the gray sky, its speed so great that it took only a few seconds from launch to impact.

boom!

The tree eight kilometers away was blown to smithereens!

The tree trunk broke in the middle, the upper half flew far away, the crown shattered into wood chips flying everywhere, and a clear crater was blasted into the ground, with dust rising and then slowly settling down.

Zhang Renfeng put down his binoculars, turned around, and smiled easily. "Commander, you'd better keep your promise."

He spoke lightly, but he was actually pondering the implications in his heart.

What makes this thing so amazing is its convenience. Even with the advent of various types of fuse-equipped missiles in later generations, the 107mm rocket launcher remains the most widely used artillery piece among many small countries.

In that era, especially given the lack of heavy firepower in the Chinese People's Volunteer Army, it was a timely help.

It could be pulled by manpower over mountains and valleys, and it could be disassembled so that each soldier could carry two rounds and run up the mountain. Once they reached the destination, they could set it up and fire, and then run away. No matter how many planes or cannons the American army had, they could not catch up with it.

Currently, the US military has changed commanders mid-battle, replacing Mike with Ridgway, and frontline logistics are strained, so he specifically returned to request reinforcements...

Unexpectedly, upon returning, I discovered my treasure boy.

The legion commander was surprised, but he tried his best not to show it.

He put down the binoculars, and his expression tightened.

He's always been straightforward; he says what he thinks. You can't expect him to pretend to be calm.

But today he managed to suppress his amazement, only grunted and picked up his binoculars to glance at the distant bomb crater.

But Director Nie was getting impatient.

"Renfeng, this thing...when did you guys start working on this? I haven't heard a thing about it!"

Director Nie was extremely annoyed. "If you had come up with this result earlier, I wouldn't have had to rack my brains to help you and Song secure the position of Minister of the Second Ministry of Machine Building. With this, who would be qualified to compete with you?"

I can't hold it in anymore! I absolutely have to brag about my family to those committee members later...

As the acting head of the General Staff, he was qualified to inquire about military equipment, but this was the first time he had ever seen such a thing. He was overwhelmed with mixed emotions, both surprised and delighted.

Before they could react, Brigade Commander Chen, Zhao Gang, Qin Jiwei, and others had already instructed Cao Huali to try out other artillery pieces.

Brigade Commander Chen leaned on his cane and approached, muttering to himself:

"Comrade Cao Huali, quick, fire another shot."

Zhao Gang, standing to the side, also became interested and rolled up his sleeves, ready to get started.

When Cao Huali explained things carefully, he exuded the composure characteristic of an engineer:

"The advantage of this cannon lies in its modular design. Each component can be quickly assembled and disassembled, and the weight of a single shell is controlled at 18.8 kilograms, which an ordinary soldier can carry while running uphill. Moreover, the firing method is flexible; it can be ignited with batteries, or it can be fired by pulling a wire, and it can also..."

He paused, glanced at Zhang Renfeng, and said, "We can also do it like Commander Zhang did, by using an open flame."

Zhang Renfeng positioned a cannonball, exposed the fuse, picked up a pine needle from the ground, and lit it...

The fuse hissed twice the moment it touched the flame, followed by a terrifying burst of flame. The shell flew out, trailing white smoke, its trajectory almost identical to the previous one, and it landed precisely near the same crater, exploding with a deafening roar.

This operation is astounding again. No, this high-tech shell can actually be ignited and fired?

Everyone present, except for the engineer division, was shocked.

"Commander, is this even possible?"

He glanced back at Director Nie, who was staring wide-eyed. "No launcher is one thing, but how can it launch with batteries? Now it can launch with fire too?"

The corps commander picked up another shell and examined it, looking at the fuse interface at the rear and the markings on the shell, muttering to himself.

"This thing...this thing is practically tailor-made for our Volunteer Army."

Director Nie sighed, "I can just imagine it. If a company of soldiers each carried two rounds and ran up the mountain, wouldn't that be...?"

He was a veteran and knew what the biggest fear in mountain warfare was: heavy firepower couldn't get up there, and even if it did, there wasn't enough time to deploy.

But this 107mm rocket launcher could be carried on one's back and driven around, set up on the mountaintop and fired, covering enemy positions eight kilometers away, and then picked up and ran away. This tactical flexibility and mobility was like adding wings to a tiger for the Chinese People's Volunteer Army fighting in the mountainous terrain of Korea.

Commander Chen remarked, "If we aimed at the enemy position from eight kilometers away and had an entire regiment unleash a barrage of a thousand artillery pieces, wouldn't that be much less effective than a Katyusha rocket?"

"The key is that this thing is lightweight. A whole regiment can be deployed, with each person carrying two. Once they reach the designated location, they can be spread out and a thousand cannons can fire at the same time. The scene... tsk, I can't even imagine it."

They didn't know the capabilities of other armies, but the iron-willed feet of the Chinese People's Volunteer Army, combined with these artillery shells, could extend their firepower eight kilometers south of the 38th parallel!

Just as everyone was in shock, the engineers hurriedly brought over a dozen gun mounts!

Zhao Gang's reaction was somewhat unusual. Besides his curiosity about the rocket, he was more moved by Commander Zhang Renfeng's simplicity and humility. He immediately mentioned the central front, then the special forces, and how they were all rushing to the Third Army Corps to carry out the most difficult and arduous tasks. He truly cared deeply for his brothers' promotions and advancement. With such a commander, Zhao Gang would have to die for him; otherwise, he would have no conscience at all. He silently shielded Qin Jiwei and Gu Jingsheng in front of him, secretly making a mental note of it…

[Under a clear blue sky, today, Commander Zhang and several others from the Third Army Corps, including Chief of Staff Zhang and Chief of Staff Chen, observed the military equipment of our corps. Commander Zhang tried his best to guide them, but Chen just watched the whole thing, his mind wandering a hundred and eight thousand miles away. This is truly a disgrace to our Third Army Corps! He has been offline for a long time, not caring about the military and political affairs of the corps. From now on, I, Old Zhao, will only recognize Zhang in the Third Army Corps, not Chen!!!]

"Tsk, Zhao Gang, what are you doing hiding in the back? Come here. You're the director of the political department of the corps. You should set an example first. How can you let the deputy commander and deputy political commissar run around like this? You don't have enough awareness."

Hearing Commander Chen suddenly call him, Zhao Gang was a little flustered. He hurriedly put away his notebook and, like a grandson, smiled and said, "Okay, Old Chen, I'm coming."

Then, obediently standing beside Brigade Commander Chen, she became at his beck and call, looking at Zhang Renfeng, "Commander Zhang, there is..."
