Jiayuguan City, the front-line command center of the Lanzhou Military Region.

Although in recent years, due to the advance of the main force of bet A to the Soviet Union, Europe, the Middle East and other places. But the Chinese region is still under no less than 30% of the beta and continues to launch wave after wave of attacks.

Therefore, including Jiayuguan, residents of many cities near the Great Wall have been evacuated. Including Jiayuguan City, the lofty mountains inside and outside the Great Wall have been fortified and militarized.

At present, the total number of troops stationed on the entire Great Wall defense line has exceeded the number of troops recorded in human military history -- 800 divisions and more than 10 million troops.

Jiayuguan City alone has stationed three divisions of troops.

Jiayuguan, as a hot spot of the Great Wall defense line, almost every half a month or so, there will be a wave of beta attacks.

A week ago, the fighters had just eliminated a group of more than 10,000 betas with the help of dense mine positions, as well as tanks, rocket artillery and other weapons!

The casualties are not large, but weapons, including mines, rockets, and artillery shells, are seriously consumed, and they urgently need to be replenished before they can carry out the next defensive battle!

"What, the central government sent people to inspect and inspect the front line, isn't this adding to the chaos? What is there to inspect, if you really have the heart, it is better to send a little more ammunition and medicine! Of the phoenix nest base? I don't know what the phoenix nest base, the phoenix nest project! Qin Laohu, the commander of the military region, was slapping the table, "Political task? The decision of the Central Committee still meets all the needs of the inspection team? Day! ”

"Guard, go to the train station, pick up people! Wait a minute...... I'll go for myself! ”

"Yes!" The guards saluted solemnly, and then began to make preparations.

Although, very emotional!

However, Qin Laohu, commander of the military region, was still busy and personally went to the railway station to pick up the inspection deputies. was already dissatisfied, but when he saw Li Feng and the others less than twenty, he was even more angry.

Inspection, inspection?

A large group of young men and girls who have not yet grown their hair are inspecting the Lanzhou Military Region, which is at the forefront of resistance to the beta, on behalf of the central government, isn't this adding to the chaos?

Due to the tight transportation capacity, only 12 million tons of materials are transported to the Lanzhou Military Region by rail every year. Don't look at the number of 8 million tons, in fact, since this is the front line of beta operations, the size of the army is more than a million.

With such a large army, even if you don't consider the ammunition consumption to fight the beta, just food, clothing, fuel, medicine, vehicles, and other materials are astronomical.

Sending a group of young masters and young ladies who have never been on the battlefield and have not grown up to the front line can not be seen to have any other effect than wasting the already tight railway capacity.

Even, in order to protect these dignitaries, there was actually a squadron of tactical aircraft on the train. I thought that these J-8 tactical aircraft squadrons were allocated to the front line to supplement combat power, but they turned out to be bodyguards.

Qin Laohu almost had a stroke.

And this tactical aircraft unit, once a dangerous situation is discovered, the first task is not to participate in the decapitation combat mission of eliminating the light class, but to ...... Escape with this group of inspectors!

Major Qin Liuli, the commander of the tactical aircraft squadron leading the team, is the granddaughter of Qin Laohu.

Seeing this granddaughter, Qin Laohu became even more angry.

The original promising ace tactical aircraft guard, since he was a child, has shown that he is more suitable for flying tactical aircraft than others, and in his old words, he was born to fly tactical aircraft.

When the Republic received the first batch of F-4 tactical aircraft assisted by the United Nations, Qin Liuli was already the first batch of academies, and then, for the first time on the battlefield, it was an amazing performance, no less than the ace tactical aircraft guards of the United States and the Soviet Union.

And then what? The state has set up a Fengchao military base, and even the level of the commander of a military region like Qin Laohu is not enough to keep it secret, and he is not qualified to know the details of the Fengchao base.

As for trying to inquire about her granddaughter, even if Qin Liuli goes home, she will refuse to disclose secrets to her grandfather, who is the commander of the military region, with organizational discipline.

Thinking of this, Qin Laohu's nose was crooked, and the dignified commander of the military region couldn't know how high the level of secrecy was? Besides, there are probably tens of thousands of people in a military base, and it can be guaranteed that no one will go wrong and no secrets will be leaked?

"Commander-in-Chief Qin, we are a team sent by the central government to the front line to experiment with new weapons." Li Feng stepped forward with a smile and said, "If the new weapons can be perfected and mass-produced and adopted, the soldiers will be able to shed less blood!" In the future, the mode of fighting will also change! ”

"What new weapon?" Qin Laohu couldn't help but prick up his ears to listen, and his glasses kept looking.

Li Feng said: "I'll know soon! ”

Commander Qin's face was pale, the young man now, it's really! Engage in these routines with an old man like him all day long.

……

Next, within a few days.

The UAV squadron and communication engineers trained in the Fengchao base have begun to continuously set up communication base stations.

These base stations are not civilian 1G base stations, but military versions of 2G base stations. Because, the 1G base station can basically only make calls and send telecommunications, and the network cannot transmit too much information.

The 2G base station has added network functions on the basis of communication, which can meet the purpose of using the wireless network of the base station to command the drone.

Of course, 2G network base stations are also excessive, and it is expected that they will soon be upgraded to 3G, 4G or even 5G networks in the future.

According to the signal coverage of the base station, the coverage of the general small mobile communication base station is about 350 meters, in order to ensure network coverage, two base stations are erected within one kilometer.

Medium-sized base stations, covering a radius of about five or six kilometers.

Large base stations, the signal coverage is more than 15 kilometers.

As for the coverage of marine base stations, it is up to 100 km.

Of course, satellite communication can be used in places that cannot be covered by ground base stations. However, for the time being, the Republic does not have communication satellites, but it will not be long before communication satellites will be launched, not only communication satellites, but also positioning satellites, meteorological satellites, and so on......

The program developed by Long Xiaoguang can be used as a drone to shoot a battlefield map, and then send it to the server to get a timely update of the battlefield map.

Once the drone has been attacked, the location of the attack will be prompted very quickly. The screen can then be brought up from the perspective of other drone footage to see what is really happening on the battlefield.

Currently, the number of drones brought to the front line by the crowd is 5,000. The factory price of each drone is about 5,000 yuan, and if you include ammunition, the cost of the drone will exceed 10,000 yuan.

The drone weighs about 100 kilograms, runs on gasoline as fuel, and can fly for three hours. At the moment, it is possible to load 50 kg of ammunition for weapons, for the time being, the bombing of the main means of attack, after all, this is the simplest. In the future, with the update of technology, future drones will have a larger payload, and they will also be loaded with machine guns, cannons, rockets and other weapons......

That is to say, the total value of drones currently transported to the front line is 50 million yuan.

Coupled with the cost of laying these base stations, the cost of large base stations is 5 million, medium-sized base stations are 2 million, and small base stations are also more than 100,000 yuan.

Large-scale base stations and medium-sized base stations need to build special computer rooms to ensure stable and uninterrupted power supply. In addition, it is necessary to engage in air conditioning to dissipate heat.

The cost of small base stations is slightly lower, and it is enough to build a shed outdoors to shelter from the wind and rain, but at least to ensure the stability of power supply, and the base stations are connected by network cable optical cables.

If the world, all parts of the country have paved high-speed broadband optical cable lines, then the construction of base stations will also be trouble-free.

At present, the total cost of Jiayuguan's experimental base station has reached 50 million yuan.
