The four people who entered the truck looked at the unknown object in front of them, some of them staring in amazement.
After a long while, Ma Guoliang was the first to ask, "Jianguo, is this the new thing you've researched?"
Xu Jianguo nodded and said, "That's right!"
"What is this thing used for?" Su Dingshan asked.
"Grandpa Su, I named these two devices 'drones'."
"Drone? What do you mean?"
"Simply put, it's an aircraft, but it's operated by a remote control."
The four of them still didn't understand what this thing was used for, so Wu Tianlong asked, "Then what is this thing used for?"
"This time, I'm designing a reconnaissance drone. When I operate it later, you'll know what it's used for. It's safe to say that with it, our troops will be invincible on the battlefield!"
The four people were still willing to believe what Xu Jianguo said, so when they heard Xu Jianguo say this, they immediately understood that what he took out this time was definitely not simple.
"Then do it quickly, let us take a good look!"
"good!"
After Xu Jianguo agreed, he did not immediately operate the drone to take off. Instead, he walked to the rear of the car, lifted the canvas curtain and looked outside. When he found that the nearest guard was also on guard a few hundred meters away, he felt relieved and directly pulled open the curtain.
Turning around and walking back to the few people, Xu Jianguo first turned on the power of the TV. When snow appeared on the screen, he picked up the drone remote control next to him and connected the video cable to the remote control.
Next, Xu Jianguo took the large drone and placed it at the rear of the truck, then pressed the start button.
With a low "buzzing" sound, the six rotors on the drone began to rotate rapidly, and then it left the truck cargo floor and hovered steadily at a height of nearly one meter, waiting for Xu Jianguo's next move.
The sudden scene made the other four people in the car open their eyes wide. They really didn't understand how this thing could suddenly fly up.
As four people who have been in the army for many years, they have seen many planes, but they have never seen such a small one, and they can't even imagine it.
But the more shocking news was yet to come. Xu Jianguo said, "The two drones I designed this time will have some differences in flight time, payload, and flight speed. You can choose one based on different battlefield situations."
The four of them listened very carefully, especially Su Dingshan and Wu Tianlong. The former listened because he had absolute trust in Xu Jianguo, and the latter listened because it was his first time testing Xu Jianguo's new equipment.
Ma Guoliang and Dong Jixiang had already come to the side of the drone. Their four big eyes were as big as copper bells, staring at the strange guy in front of them without blinking. At the same time, their big faces appeared on the TV screen, but everyone's attention was now on the drone, and they were not paying attention to the TV at all.
"Don't just look at the drone, the key thing is on the TV!" Xu Jianguo said with a smile as he looked at the four people.
After his reminder, the four of them finally reacted and quickly turned to look at the TV behind them.
"Huh? Why does the picture on TV look so familiar?" Dong Jixiang walked over and asked.
The other three also nodded, then looked at Xu Jianguo, waiting for his answer.
"The images we are seeing now are captured by the drone's camera. I have also integrated some of the night vision and infrared thermal imaging functions into the camera, and these two functions are the greatest uses of this reconnaissance drone."
After hearing Xu Jianguo's words, the four of them looked at each other, seemingly confused. Finally, Su Dingshan took the lead and asked, "Jianguo, what is this camera you're talking about?"
"Grandpa Su, you can think of this camera as a human eye, except it's an electronic device, so it can also be called an electronic eye. The ultimate mission of the reconnaissance drone is to fly high into the sky and transmit what the electronic eye sees to the television. That way, even if the enemy deploys a large number of military equipment, we'll be able to detect it immediately."
"Hiss~"
For the four veterans, they knew very well the meaning of what Xu Jianguo had just said, and they also knew its importance.
What's most important in war? Weapons and equipment are a given, but are weapons and equipment enough? The answer is no. Intelligence is always the most important thing.
The so-called anticipating the enemy's advance means that if you can grasp the enemy's entire troop deployment without anyone noticing, you will have absolute initiative in the war. It can even be said that, barring any unexpected events, you have basically won the war. What remains is a matter of how and how many enemies to kill.
While the four people were still in shock, Xu Jianguo operated the remote control in his hand and pointed the drone's camera at the five people in the car.
Soon, the figures of five people appeared on the screen, which shocked Su Dingshan and the other four again. After all, they had heard about it, but when they saw it in front of them, they still found it a little unbelievable.
Ma Guoliang even waved in the direction of the drone, and he saw himself waving his arms on the TV screen.
"Wow, I never thought that one day I would be able to see myself on TV. This feeling is simply amazing." Ma Guoliang said.
At this time, Su Dingshan was the one who noticed something was wrong. He looked at Xu Jianguo and asked, "Jianguo, it's so dark in this carriage, but the light from your camera looks just like daytime. Is this the function of the night vision device you mentioned?"
"That's right, Grandpa Su. The principle is similar to the low-light-level night vision device I researched before, except that it's been integrated a bit."
"You just said there was a red or something, what is that?" Wu Tianlong also asked at this time.
"Infrared thermal imaging is also a function of the camera."
"What do you mean? Tell me more specifically!"
"The average human body temperature is around 36 degrees Celsius, which is a biological heat source. Therefore, if we can detect an object with a temperature above 30 degrees Celsius using infrared light waves and sensors, it can be considered a living object. Imagine if the enemy sets an ambush at night. It would be difficult to detect them with the naked eye. However, if we have a drone equipped with infrared thermal imaging capabilities, we can detect the enemy from several kilometers away, lock on to the target through thermal imaging, and then strike and annihilate them."
