The working principle of infrared thermal sensing detectors is mainly to detect differences from the temperature in the background. Among them, where the temperature is low, the blue light map appears; where the temperature is high, the light map appears in the red light map.
The five people in the mercenary team, wearing full-coverage helmets and integrated camouflage combat uniforms, were actually to prevent the body temperature and heat from dissipating into the air, which was different from the surrounding environment, and were discovered by infrared thermal sensing detectors.
The fifth main combat team of the Devil Mercenary Group behind the Punishment Mercenary Team is tracked. They all have anti-infrared thermal sensing detection combat uniforms, which can also avoid being discovered by armed helicopters in the sky.
However, whether it is the guys from the Devil Mercenary Group or the members of the Punishment Mercenary Team, the iron guys riding under them do not have anti-infrared thermal sensing detection devices.
In order to obtain powerful off-road performance, mountain motocross must have a powerful engine. To put it bluntly, every powerful chemical energy engine is engine that uses fuel, and they will definitely emit a lot of heat, especially the engine itself and the exhaust pipe.
The engine itself must cool down to maintain normal operation; the exhaust pipe discharges the high-temperature exhaust gas released by combustion inside the engine, which also causes the exhaust pipe to have amazing heat.
These heats become the target of tracking by armed helicopters in the sky!
Shi Lei's voice came from the Bluetooth headsets of all members of the Punishment Mercenary Team, "Give up the mountain off-road motorcycle immediately. More than a kilometer away from you, an armed helicopter is flying over, probably because it detected the heat emitted by the mountain off-road motorcycle. You only have fifteen seconds to escape!"
All members of the Punishment Mercenary Team received a message from Shi Lei, and stopped the mountain off-road motorcycle without hesitation, and then abandoned the car and ran. It would be completely unrealistic to ride a mountain off-road motorcycle with an armed helicopter in the dense forests of the mountains. If they did not abandon the car, they would not have any chance to escape. Instead, they abandoned the car and ran away, and there was still a little chance.
Five seconds later, the members of the Devil Mercenary Group heard the sound of propellers of armed helicopters in the sky. They made the same judgment as Shi Lei. They directly abandoned the mountain motocross and did not continue to chase Ye Feng, but retreated backwards.
Dick, the fifth main combat team of the Devil Mercenary Group, is quite judging. He knows clearly that the armed helicopters in the sky have discovered mountain motocross on the ground. Once the people tracked by them in front also hear the sound of propellers of the armed helicopters, the people in front will definitely come back to cause trouble for them. So they do not go ahead, but choose to run back.
Unfortunately, no matter how judged Dick was, he could not have imagined that Ye Feng they were following was not from the South Vietnamese, but also from the South Vietnamese enemy.
Dick led five members of the fifth main combat team of the Devil Mercenary Group to retreat to the rear, trying to avoid the search of armed helicopters in the sky.
Ye Feng led the four members of the Punishment Mercenary Team to run quickly in the mountains. They could no longer care whether the ground would leave footprints, and the enemy would follow these footprints to follow them.
Now is not the time to worry about these problems. Their most important goal is to stay far enough away from mountain motocross to avoid being affected by them.
"Boom boom boom boom~"
Behind the Punishment Mercenary Team, three loud explosions came. They were armed helicopters in the sky, directly attacking the mountain off-road motorcycles of the Devil Mercenary Group. It happened that the aviation machine guns exploded three of them.
"Conceal, keep the action prohibited!" Ye Feng notified other members on the Bluetooth headset network to minimize activities and reduce heat generation, thereby preventing heat dissipation.
However, a strange thing happened. The armed helicopter hovering in the sky did not directly attack the mountain motocross riding by Ye Feng and others. Instead, they took the initiative to contact the command center. This was because the mountain motocross riding by Ye Feng and the five men came from a secret military warehouse on the border, belonging to the real Nanyue side's equipment, and an enemy-to-me-identification code transmitter was installed inside.
"The call command center and the call command center found five mountain off-road motorcycles. According to the enemy-we-identification code system, these five mountain off-road motorcycles originated from the secret military warehouse of the S035 border. About one kilometer behind the five mountain off-road motorcycles, there are several other mountain off-road motorcycles, but these mountain off-road motorcycles are not owned by us. Now, please request the latest command of the command center." The pilot of the ach-47 armed helicopter asked the control center for the processing order.
"Ha004 Please wait. The command center is checking the usage records of the five motorcycles." The command center's military network quickly found the ownership of these five military mountain off-road motorcycles, and also had the latest dispatcher's signature list.
According to the records, the command center immediately contacted Captain Tao of the s035 border secret military warehouse, "Tao Dekai, the rank of major, and the patrol captain of the s035 border secret military warehouse. Hello, this is the command center of the Northern Operations Command. Major Tao, before you were attacked today, you personally approved and mobilized five military mountain off-road motorcycles containing our enemy and us identification code chips. So where are the five military mountain off-road motorcycles now and who are using them?"
Tao Dekai said with a little complacent tone: "The five military mountain motorcycles were handed over to your Captain Ye of the Northern Operations Command! He and his team members have left the secret military warehouse on the s035 border."
"Major Tao, which Captain Ye is it?" The personnel in the command center always maintained a consistent and calm tone, as if there would never be any emotional expression.
"It's Captain Ye who brought rice to us s035 today. He came here just after six o'clock this morning, with five trucks of rice full of." Tao Dekai explained in detail.
The tone of the personnel in the command center of the Northern Operations Command finally changed, "Major Tao, our Northern Operations Command has not sent any personnel to the secret military warehouse on the s035 border today. Are you sure you asked Captain Ye's code words?"
The garrisoners and cargo transporters of the secret military warehouse on the border cannot have any identification documents, but in order to ensure the smooth handover between the two parties, they will always get a code word after receiving the task. As long as they meet the code word, they will be their own.
The cold sweat on Tok Dekai's face was frightened in an instant. He did not sign with Ye Feng at all, and he did not get the corresponding code word prompt in the query system of the Northern Operations Command.
This means that Ye Feng is not a member of the Northern Operations Command at all. The detailed information he inquired was not reported by the Northern Operations Command at all. After all, shortly after Ye Feng arrived at the base, the S035 base was attacked, which was a bit too strange.
"Major Tao, that Captain Ye is a member of the Northern Operations Command, right?" asked the Northern Operations Command and the command center personnel.
Tao Dekai responded helplessly: "That's right! He is a fake person! I have neglected my duties and I am willing to accept punishment!" Tao Dekai knew that he was finished. The secret military warehouse on the s035 border was attacked, so he couldn't leave any connection.
The command center got the accurate answer and immediately fed back to the ach-47 armed helicopter numbered ha004.
"Ha004 Please note that this is the command center, tracking people using five mountain motocross in our country. The five people pretended to be personnel from the Northern Operations Command and have been defined as enemies. The command center authorized the free fire!" The personnel of the command center ordered the armed helicopter.
The armed helicopter numbered ha004 immediately responded: "ha004 understands that the order has been received!"
...
Xia Kingdom, Shuangqing City, Jingyayuan.
Shi Lei had just cracked the monitoring authority of the Northern Operations Command. He monitored various intelligence information from the command center in the internal network of the Northern Operations Command.
All the information will be judged by Yi Zuer once, and Yi Zuer will screen and determine the information that meets the keywords set by Shi Lei. For example, Yi Zuer specially screened out the information of the fake personnel just now.
Shi Lei checked the information selected by Yi Zuer. He had originally looked a little pale because he stayed up late and had a little pale face. He contacted the five members of the Punishment Mercenary Team through Bluetooth headphones, "Please note that you have been marked as impersonators by the South Vietnamese Kingdom and have become the absolute enemies of the South Vietnamese Kingdom."
"Boss, what direction should we go now to get out of danger?" Ye Feng asked Shi Lei, hoping to get Shi Lei's remote support.
Unfortunately, Shi Lei cannot provide remote support for the time being!
"Afeng, you cannot provide map information for the time being. You use the compass to guide the way. Your final destination is Meishan Island. Once you arrive at Meishan Island, you will be safe!" Shi Lei said with regret.
Ye Feng did not express his dissatisfaction or other attitudes. He just responded: "I understand, boss."
Over the dense forest, the armed helicopter numbered ha004 was calling for support from other armed helicopters. If the five men from the mercenary team were punished, they were unable to leave the dangerous area of the secret military warehouse on the border for the time being, I am afraid they would be really in danger!
The Punishment Mercenary Team is the sharpest sharp knife in Shi Lei's hand. Shi Lei does not want to lose the Punishment Mercenary Team at all, but the damn Devil Mercenary Team suddenly arrived, and Shi Lei had no choice but to fight.
Two minutes later, three armed helicopters had gathered over the dense forest where the Punishment Mercenary Team was located. Ye Feng looked at the fault of the forest not far away. He contacted Shi Lei and said, "Boss, we are in a desperate situation. There are faults in the dense forest ahead, and we cannot continue to isolate the threatening eyes from the sky. There are also followers behind. The paratroopers from the South Vietnamese Kingdom participated in the war. They can arrive in the latest fifteen minutes. Boss, what should we do now?"
