Chapter 96 Smog and Laser Protection
In the live broadcast room of the military website, the host and several guests, including Zhang Zhong, were watching the exercise and chatting about the details.
Suddenly, the host, who was chatting idly, seemed to receive something and naturally ended the current topic, looking at the scene on the exercise screen and smiling.
"Teacher Zhang, both sides have now activated communication jamming in the exercise. The Blue team has also used electromagnetic interference to destroy the Red team's drones."
However, we observed that a number of Red Team drones remained unaffected and continued to advance towards the Blue Team's positions.
The command center reported that these drones all adopted electromagnetic interference protection design and real laser communication technology.
I understand electromagnetic interference protection design, but what's this about laser communication? I've only ever heard of laser guidance before.
Laser radar, and laser weapons —”
"Laser, huh? That's an old technology."
Zhang Zhong thought for a moment and explained: "Laser theory originated from Einstein's principle of 'stimulated emission' a hundred years ago, which was first discovered in the United States in the 60s."
Because of the unique stability and energy concentration of lasers, they can propagate over long distances with low loss, leading to applications in laser guidance, laser radar, laser communication, and laser weapons in just a few years.
In the 1980s, foreign countries began using laser weapons to blind enemy sensors and simultaneously completed experiments on satellite-to-ground laser communication links.
In the 21st century, the United States completed multi-link laser communication within the atmosphere a few years earlier, with the communication distance within the atmosphere exceeding 300 kilometers, and officially announced the practical application of laser communication. Laser weapons have also developed into the high-energy field, no longer limited to blinding, but capable of directly destroying objects with lasers. Our research in the field of lasers started relatively late. We only completed the first space-to-ground laser communication link test in 2011, which is 30 years later than other countries.
Earlier this year, due to a breakthrough in semiconductor laser devices.
We now have better devices, enabling stable communication over a 30-kilometer radius with six links within the atmosphere, which is the laser communication we see on the Red Team's UAVs.
Of course, this is still a long way from the 8x8 64 link achieved by the United States using optical phased array technology, which enables 300-kilometer laser communication within the atmosphere. However, our researchers are working hard to catch up.
"So this is laser communication."
The host suddenly realized what was going on and continued, "So, what do you think the Blue Team has to do to solve this communication problem?"
"Actually, it's quite simple. Laser communication sounds very high-tech, but it's just a beam of light connecting two communication terminals. As we all know, light travels in a straight line and cannot be blocked."
Zhang Zhong pointed to the signal points of the Red Team's drones on the big screen: "Look, all these Red Team drones have received laser signals."
Based on the principle of multi-point positioning, the location of the red team's laser communication base station can be easily locked, and then destroyed with artillery shells.
However, modern artillery is constantly mobile, without fixed positions or routes. Now that wireless communication between the two sides has been cut off, the Blue Force command will likely be unable to contact its artillery for some time.
"Does that mean the Blue team is helpless?"
The host's eyes widened slightly: "They've tied themselves in!"
"There's another way."
Zhang Zhong smiled and said, "I've looked at the Blue Team's defense map. They have an anti-aircraft artillery position. We can try using live ammunition to block them."
"live ammunition?"
The host exclaimed in surprise, "Teacher Zhang, this is a drill!"
"It's live ammunition, or more accurately, smoke bombs with live ammunition."
Zhang Zhong said seriously, "Smoke grenades can be carried in the exercise and can naturally be used in practice."
Lasers are essentially light, and they are most vulnerable to smoke, fog, and tiny particles, which can severely weaken their intensity.
This is similar to driving at night. When the weather is good, the headlights can illuminate a long distance, but when it's foggy, the headlights can only illuminate a small area in front of you.
In this way, the Blue Team only needs to adjust the angle of the anti-aircraft guns and fire a few basic smoke grenades into key areas of the battlefield, and the laser communication will be blocked.
After all, the Red Team's laser communication range is only 30 kilometers, and the technology is not very advanced; it would be cut off if there was even a little bit of smoke.
Actually, I've always thought that the severe smog in China is, in a way, an effective means of defending against laser weapons.
Blue Team Command Post.
Xu Zelin and a group of Blue Team staff officers stared wide-eyed as they saw the drone still flying in the sky through the fixed anti-shielding lines.
"Artillery! Artillery! Quickly notify the 3rd and 4th Artillery Battalions to locate their communication base stations at multiple points and shoot down their laser base stations!"
"Laser communication? Damn it, the Red Team is using us Blue Team as a whetstone for new technology, they don't want to give us any chance at all!"
After a three-second pause, Xu Zelin was the first to react and immediately roared out the order.
As a commander who has been on the front lines for a long time.
In order to ensure command acumen, Xu Zelin and others have long paid attention to and conducted targeted simulations of various technologies around the world that may affect the battlefield situation.
In addition, the absence of American representatives who projected their own views onto others and preconceived notions that the exercise was faked meant the exercise was not conducted.
Seeing that over a thousand drones hadn't landed, without needing laser spyglasses, the reason was quickly guessed.
This involved more than half a month of training and numerous simulations.
They believed that the Red side had measures to prevent communication interference.
It's nothing more than fiber optic drones, or special anti-electromagnetic interference drones, paired with artificial laser point guidance.
In this way, no matter what the situation, they can track down the Red Army soldiers and then launch a counterattack using the artillery battalion that was saved at the cost of the entire front line.
Instead of constantly playing man-machine battles like we do now, where all we see are drones and no humans, and we're the only ones getting beaten up.
But I didn't expect it.
This is the first time in China that laser communication technology has been directly deployed.
This made Xu Zelin suspect that the headquarters was planning to stop operating and let the Red Army use all the good stuff.
"The 3rd and 4th Artillery Battalions are 10 kilometers away from our command post. Wireless communication is currently blocked, so we can't contact them for a while."
The chief of staff hurriedly responded: "Use anti-aircraft guns! Firing smoke grenades will disrupt laser communications!"
"However, in modern warfare, anti-aircraft artillery is the last line of defense for protecting command posts and important communication nodes, and it cannot be used lightly —"
At this moment, a staff officer chimed in, looking somewhat worried, "Once this anti-aircraft artillery position is exposed, the Red Army can quickly pinpoint the area around our command post and various core communication hubs, and then locate our command post."
"this----"
Upon hearing this, Xu Zelin looked at the defensive line situation displayed by the fixed-line camera and a hint of hesitation flashed in his eyes.
Now the Red team only has about a thousand drones left, which has significantly reduced their offensive capabilities. Their defensive line is no longer under as much pressure, and they can fully support the messengers to reach the artillery battalion to relay orders.
Modern warfare is all about information.
At this point, due to the disruption of wireless communication, the command center was already 90% blind and at great risk of being attacked. If they were to deploy anti-aircraft artillery now, exposing their core area, the consequences would be unpredictable.
"Reporting, sir! Urgent report from the position: the Red Army has deployed another swarm of drones, approximately 800 in number, requesting support—"
At this time.
Before Xu Zelin could make a decision, the operator rushed over and hurriedly handed him an urgent intelligence report.
"beat!"
Upon seeing this intelligence, Xu Zelin immediately stopped hesitating and resolutely ordered, "Immediately contact the anti-aircraft artillery positions and fire smoke grenades intermittently to seal off the entire border between the Red and Blue teams and disrupt the Red team's laser communications!"
Exposing risks, even if they are indeed exposed, is something for the future.
However, if the Red Team's laser communication is not blocked, a complete collapse is imminent, with no possibility of a future crisis.
"yes!"
Upon seeing Xu Zelin give the order, the staff officers and commanders around him hurriedly made arrangements.
One part of the task involves using the sand table to simulate the blocking nodes of the smoke bombs, another part involves contacting the anti-aircraft artillery positions to prepare smoke bombs and adjust their angles, and yet another part involves simulating which anti-aircraft artillery units to use, all of which can minimize the risk of the command post being exposed.
Bang! Bang bang bang!
In less than three minutes, anti-aircraft smoke grenades were launched from the rear of the Blue team, whistling through the air and flying in arcs toward the Red team's position.
boom!
Boom!
The delayed fuse was triggered, and the smoke grenade exploded in the sky, spreading out dense, persistent smoke.
The Red Team's drone swarm, which was still attacking, paused in the sky for a moment, and then began to land in large numbers due to communication interruption.
Red Team Position.
Having just used drones to wipe out the Blue Team's artillery battalion, Lin Dong and the others, who had gathered together, couldn't help but raise their heads upon hearing these completely different sounds.
"Anti-aircraft guns! Live ammunition firing from anti-aircraft guns!"
Zhang Yihao turned on his low-light night vision goggles and watched the plumes of smoke exploding in the sky.
Based on the identification knowledge he had learned in the past two weeks of training, he couldn't help but excitedly shout: "This is a live-fire anti-aircraft gun! The Blue Team has fired live smoke rounds from their anti-aircraft guns!"
"That sound and that shooting angle—Forest No. 46."
Lin Dong looked up and then turned to Xu Hua not far away: "Based on the anti-aircraft artillery deployment rules, the area protected by this anti-aircraft artillery array happens to match one of the command post locations you analyzed."
"That's right. I've always said that I understand my grandfather better than he understands himself when it comes to setting up defensive positions."
Xu Hua took a deep breath, excitedly wiped the dew off his helmet with both hands, and gazed at the distant, dark mountains and forests.
"Commander Xu of the Blue Team finally couldn't hold back and gave himself away!"
