"What, all attacking troops suspend their attack operations? The headquarters will send unmanned reconnaissance aircraft troops to all frontline troops for cooperation and will arrive within today?"

"Unmanned reconnaissance aircraft, what does this mean?"

"Is it another new weapon we invented?"

"Can the plane fight a war without manned?"

"Wow. It's amazing! It would be so cool if you could fly an unmanned plane to fight the Japanese!"

"Yes, then we don't have to die so many people!"

"Hey, what are you thinking? The plane can fight without flying. How is this possible!"

"Who knows, what's strange about our chief officer using his ability to create unmanned combat aircraft!"

"Well, that's true, but I still think it's unlikely!"

After reading the message, Yang Chengliang and others' heads were buzzing, and a group of people stared at each other, completely unable to understand what the UAV was.

Everyone discussed it for a long time, but they didn't know what was going on. They just agreed that their research institutions had invented some powerful new weapons.

"Okay, don't you know when our drone reconnaissance unit arrives? I'll send me an order and let the frontline troops stand on standby and wait for the next order."

Yang Chengliang was full of curiosity and expectations at this moment. He hoped that the drone reconnaissance troops sent by Yang Fan could solve the current problems and enable them to launch an offensive with ease and pleasure.

"Here you! The drone reconnaissance unit is finally here!"

After waiting for a long time, two large sea knight transport helicopters appeared over Huaiji County with a flapping edge.

"Let's go and have a look!"

Yang Chengliang, who was full of curiosity, could not hold back and hurried out of the command center and led a group of officers to a square in the county town.

Soon, four Sea Knight transport helicopters stopped steadily in the square under the gaze of everyone.

Immediately afterwards, 125 technical soldiers of the Hu Ben Army wearing military uniforms and backpacks walked off the helicopter and began to line up to report the number.

After completing the entire team, a leading officer ran quickly to Yang Chengliang and others standing not far away.

When he ran to the front, the officer saluted in awe: "Report to Commander Yang, I am Lu Dongqi, the captain of the 6th battalion of the drone, and was ordered by the headquarters to come to the 5th Army to report.

After the 6th brigade gathered, 85 people should arrive, 85 people should arrive, please give instructors!”

"Very good! Captain Lu, on behalf of all the officers and soldiers of the 5th Army, I welcome all the brothers to the arrival of you!"

Yang Chengliang replied with a good mood. After a few polite words, he asked anxiously, "Captain Lu, can you introduce me to what you are doing first?"

"OK!"

Lu Dongqi nodded with a smile, and then began to explain in detail.

It turned out that as early as a month ago, when the system mall unlocked the drone, Yang Fan began to secretly form a drone reconnaissance force.

After one month, Yang Fan finally initially trained eight brigades of drone reconnaissance troops.

Each drone brigade has a full capacity of 85 people, a brigade headquarters is 4 people, and another 3 27 squadrons are under its jurisdiction.

The new technology has high confidentiality and priority levels, and all people come into contact with high-tech products. Not only do people need considerable culture and professional skills, but they also have to be loyal and reliable. Therefore, it is really easy to cultivate.

Thanks to Yang Fan's reserve of enough talents, he was able to train six or seven hundred drone technical soldiers in a short period of time.

Even so, there are only a few people at present. The first-level combat units of the group army can only be equipped with one drone brigade, which is divided into each army, which is a drone squadron with 27 people.

Like the modern drone industry, drones in Taobao malls are currently divided into three levels: consumer, industrial and military drones.

Among them, consumer-grade drones, which are entertainment-type drones used by ordinary people, rely mainly on radio, so the communication distance is usually relatively short.

Many image transmission or digital transmission suppliers indicate communication distances between 5km and 10km (of which 5km is the most common).

However, during actual use, it is affected by environmental factors, such as undulating terrain, urban buildings, high-voltage wires, etc., and the effective distance is generally 1km.

The communication links of industrial-grade drones mainly rely on radio communication between ground stations and aircraft fuselages.

Some ground stations use directional antennas, the most common one is the eight-eye antenna, which is used to enhance the communication frequency intensity.

In this way, the usual distance is between 20km and 30km. No matter how far the distance is, it will be affected by the earth's curve and the quality of communication will drop significantly.

Military-grade drones are at the highest level. If you look at them from the communication link, they can be divided into three types:

The first type is that both military-grade drones and ground stations are equipped with directional antennas, which keeps illuminating each other during flight, thus having good communication quality. The communication distance of this method is generally 100-150km.

The second type is to configure multiple drones to form a communication system. Each drone is equipped with a directional antenna. There is often a "ball" on the nose of the drone, which is a directional relay antenna.

Through directional antennas, drones form relay communication links between each other and finally establish a communication link with the ground control center. This way, the communication distance can achieve effective communication of 200km-500km.

The third type is to use satellite communication, that is, the drone is equipped with satellite antennas, so a big bulge will form on the head of the drone. Because the satellite antenna is large, it must be rotated omnidirectionally to ensure and always aim at the satellite.

After configuring the satellite antenna, the drone can directly establish communication links with satellites in space, and then establish a real-time transmission link between the satellite and the ground control station.

This method is very far away, and can control one end of the earth and the other end, such as the US RQ-4 "Global Hawk".

The rq-4 Global Hawk UAV is a large UAV with a wingspan of nearly 40 meters and aerial weight of nearly 7 tons. It can fly at an altitude of more than 30 hours at 18,000 meters, and its maximum range reaches more than 22,000 kilometers. It can be said to be flying around the world.

It can provide the rear commander with the ability to observe the battlefield or monitor local targets, and the daytime surveillance area exceeds 100,000 square kilometers.

It also has the potential ability to perform spectrum analysis intelligence work, discover crises and conflicts around the world in advance, and can also help guide the Air Force's missile bombing to reduce the situation of misses.

It can be said that Global Hawk is the most advanced drone in the US Air Force and even the world.

However, there is no satellite in the current time and space. Otherwise, no matter how expensive the system mall is, Mr. Yang will definitely create a "Global Hawk" and monitor the enemy's every move without blind spots.

Yang Fan can only settle for the second best. The reconnaissance aircraft used in the army are the most advanced military drones, and multiple drones can also be equipped with a long-distance communication system.

As for the more advanced integrated detection and attack armed drones, the system mall has not been unlocked yet. I am afraid that no special situation will occur, so it will be difficult to unlock.

Because in that case, it is undoubtedly a dimensional reduction attack, and there is no balance at all.
Chapter completed!
