Dreaming back to 1949, the great powers were there to deceive us

Baratu just stuck his head out of the tank when he heard Hao Dapao roaring on the intercom.

"These bastards, I've already come right up to them, and they're setting fire to our joint venture. Isn't this stealing our business?"

Once napalm gets on your body, you can't get it off because it contains a sticky substance.

Baratu had already seen the burning soldiers in the distance. He wailed for a moment and then fell to the ground motionless.

Although Hao Dapao complained, his tactical skills were really good. When he found that the front was engulfed in a sea of ​​fire, he immediately ordered the elimination of the remaining enemies. This task was undertaken by the infantry following from behind.

The armored battalion is a technical branch of the army and is difficult to train, so they are never allowed to charge with rifles.

The enemy's position is mainly inside the mountain, and we are not interested in engaging in hand-to-hand combat. If you find a cave entrance, throw a few grenades first. If that doesn't work, use high explosives to blow it up.

The infantry also carried flamethrowers, and when the fire-breathing kids found the entrance to the cave, they sprayed fire into it.

This scene reminded Baratu of Iwo Jima, except that the intensity of today's battle was far less than that of Iwo Jima. The enemy, dispersed by the armor, was completely unable to organize an effective resistance.

Although the vanguard commander Hao Dapao is reckless, he has mastered the essence of armored assault.

The battle of Paohengang is no longer a foregone conclusion. What remains is whether we can destroy or capture the enemy artillery, which is the main task tonight.

Beneath the sea of ​​fire is a nameless mountain range, but from today on, this mountain range has a name: Fire Ridge.

Hidden within the dozen or so mountains of Huoling is an artillery regiment led by Qu Zhongqiu.

The name "Quzhongqiu" comes from the story of Jiang Taigong fishing in the classic novel "Investiture of the Gods". At that time, Xibohou Jichang asked Jiang Taigong why he used a straight hook to fish, and the latter replied:

Rather, take the straight path.

Don’t seek in the song.

Not for Jinlin,

Only fishing for kings and dukes.

The song asks for this name purely as a warning to oneself: one must take the broad road and not attempt shortcuts.

Qu Zhongqiu stood in front of the map and said seriously,

"Comrades, you can see that the opposition's firepower is formidable. They have planes in the sky and heavy artillery on the ground, and these are just proxies supported by the US. If one day we were to face the US directly, they would have air superiority, naval superiority, and terrifyingly strong army firepower. Comrades, how would we defeat such an enemy?"

"Fight them!"

"Yes, fight with them!"

Qu Zhongqiu held his hands in the air, his mood not affected at all by the sea of ​​fire outside, and said with a smile,

"To deal with such an enemy, bravery alone is not enough; wisdom is also required. Now, we need to discuss how to ensure the survival and mobility of artillery without air superiority!"

The commanders and fighters discussed the matter enthusiastically, saying that the experience gained in actual combat would play an important role in the future.

……

At the Panlongshan Underground Research Center, researcher Zhang Tao jumped up and said excitedly,

"I understand!"

Everyone looked at him quickly with eager eyes.

Zhang Tao saw that he was being stared at, his face turned red, and he said,

"If we know the trajectory of the shell, we can capture it accurately!"

"Lao Zhang, are you half asleep? If we knew the trajectory of the shell in advance, would we still need to detect it?"

Zhang Tao grabbed two radar scans and explained,

"Look at these two pictures. When we don't know the trajectory of the artillery shell, the signal we capture is very weak. But if we know the trajectory, the signal is very strong and can be captured multiple times. What does this mean?"

"What does that mean? Do we need to learn the I Ching and calculate the direction of the incoming artillery shells?"

"Hahahaha!"

Zhang Tao looked at a thin old man and asked expectantly,

"Professor Wan, have you thought of anything?"

The old man stared at the blueprint in Zhang Tao's hand, and suddenly realized and shouted,

"That's right! We can do it in two steps. The first step is to roughly detect the direction of the shell. The second step is to concentrate on the radar signal scanning!"

Immediately, a researcher raised a question.

"Wouldn't that require two radars? That would be a huge burden on the soldiers."

Professor Wan smiled and said,

"Any technology develops from immaturity to maturity. Let's first develop it and then improve it. Oh, and we should also test the needle beam suggestion given by foreign experts as soon as possible."

The so-called foreign expert is Hu Zhenhua.

Lao Hu only understands the basic principles of artillery reconnaissance and positioning radar: using phased array antennas.

Phased array antenna is an array antenna composed of many antenna elements.

These antenna elements are arranged in a regular pattern, both electrically and physically. By controlling the phase and amplitude of the signal transmitted by each antenna element, the direction of the resulting beam can be altered. This is like a group of people shouting together. If the timing (phase) and volume (amplitude) of each person's voice can be precisely controlled, the sound can be propagated in different directions.

In radar, this method can be used to quickly change the shape and direction of the beam, achieving simultaneous tracking and scanning of multiple targets, greatly improving the radar's flexibility and detection efficiency, which is very critical for detecting fast-moving targets such as artillery shell trajectories.

Phased array radar can design the beam into a fan-shaped beam for wide-area search, covering a larger airspace range to detect artillery shells coming from different directions; it can also form a needle-shaped beam for precise tracking of specific targets and obtain more accurate artillery shell trajectory information.

As for how these things are achieved specifically, Hu Zhenhua is not clear.

Zhang Tao said excitedly,

"I'll study needle beams!"

There has never been overtaking on a curve in the industry. If there is, it is just plagiarism and it is impossible to surpass.

……

At Huoling, Qu Zhongqiu glanced at his watch. He felt it was time, so he glanced at the guard next to him. The latter understood and left quietly.

The guard turned and walked into a secret room, which was the ventilation hub of the tunnel. He dragged a gas cylinder from the corner, unscrewed the valve, and quickly evacuated.

After about a few minutes, all the warriors in Huoling Mountain fell into a coma.

Qu Zhongqiu leaned on the table with a slight curve at the corner of his mouth. In order to prevent the high concentration of ether from harming the soldiers, Qu Zhongqiu started the exhaust equipment before he fell into a coma.

……

Outside Fire Ridge, the flames from the napalm bombs gradually died down, and Hao Dapao yelled at the top of his lungs,

"Everyone, pay attention! Search the entrance immediately. We must find the artillery position!"

As soon as he finished speaking, a soldier shouted,

"There's an entrance here!"

Hao Dapao quickly shouted,

"Quick! Get the gas tanks ready!"

Observer Balatu did not think that the ether prepared by Hao Dapao was of any use. Ventilation was the primary condition for any tunnel or air-raid shelter, and there were many ventilation ducts. It was unrealistic to expect the enemy to fall into coma with just a small entrance!

As soon as the cave entrance was opened, something unexpected happened. Surprisingly, there were still soldiers awake inside. Seeing the enemy, they fired a volley of bullets at the entrance! Three soldiers digging the entrance were hit and fell in a pool of blood! Without hesitation, the following soldiers pulled the pins of their grenades and threw them in!

With a loud bang, the soldiers in the tunnel were blown into a bloody mess!

Hao Dapao was so exhausted that he almost wanted to die. No matter how well-planned he was, there were still loopholes! The passages inside the mountain were complicated, and there were always places where ether could not flow.

Hao Dapao roared hysterically,

"Gas tank!"
