Zhang Yuan sat on the co-pilot of the cheetah car with the edge of the window on his right hand and looked at the place where the desert and the sky met in the distance on the right, and then his eyes slowly moved up to observe the clouds in the sky.

The communication place is gray, and the good morning sun can't shine through there, and the closer you go, the lighter the clouds become, and when you get to the top of your head, it's a rare sunny day, which can be regarded as having some summer looks.

However, Zhang Yuan's expression was very solemn.

The Cheetah 2030A runs on Highway 4, followed by a mobile weather radar vehicle, a weather monitoring vehicle, a communication vehicle, a cooking vehicle, a fuel vehicle, a supply vehicle, and two nine-seater troop transport-type off-road Iveco. This is the full strength of the field detachment of the Beikuradar Station, and Zhang Yuan personally leads the team.

The two technical officers in the back row of the Cheetah wrinkled their brows to check the latest weather data from the National Meteorological Observatory and their analysis and forecasts.

The road is in very good condition, military control has been imposed in both directions, and now all military vehicles are running on Route 4. Two rest ports in the no-man's land were temporarily requisitioned, one of which was used as a field command center.

Zhang Yuan is leading the team to the field command center codenamed "Eagle's Nest". In front of them was a convoy of a company of an artillery battalion in a certain place, and they dispatched three Shuangsan7 antiaircraft guns and three Hongqi-7 short-range anti-aircraft missiles to provide short-range anti-aircraft defense for the field command center.

If these close defenses were needed, the Falcon Brigade would be close to defeat.

The weather radar detachment is the last detachment, and the logistics support detachment and the aircraft maintenance detachment have been in place for several days, and they will be able to complete all the preparations before dark today, and they will be able to support the fighters landing on Route 4 at any time and allow them to take off again.

Since ancient times, the primary condition for fighting a war has been that logistical support is in place, and only then can combat operations be carried out only if the grain and grass are not moved.

One of the technical officers in the back row of the cheetah car raised his head and took a deep breath, glanced at his comrades, confirmed his eyes, and then reported to Zhang Yuan, "Director, the probability of a sandstorm is sixty percent, and the direction should be due east." ”

That's what worries Zhang Yuan.

Don't look at the blue sky overhead now, the weather in Beiku can change, especially in the no-man's land. The reason why it is called no man's land is because the environment is harsh and inhabited. Harsh environments include weather.

When the sandstorm comes, the fighter plane can fly, but it is only the power of nature.

"Pay close attention, the next move of the troops depends on the conclusions of our side, it must be 100 percent accurate, I want 100 percent accurate data." Zhang Yuan said in a deep voice.

The two technical officers said in unison, "Yes!" ”

The meteorological detachment was under great pressure.

The convoy entered the Eagle's Nest field command center, which had changed greatly, and the field camp composed of more than a dozen large tents was impressively there, and the tent camouflage they used was desert camouflage, which was different from the woodland camouflage used by most troops.

The entire field command center was unmistakably from the rest of the desert surface from the air, and the original bungalows in the rest port were all requisitioned, and the exterior was covered with desert camouflage camouflage nets. It can be seen that the work of the base guard battalion is very good.

After the North Reservoir Station was upgraded to a combat training base, the guard company was also upgraded to a guard battalion. When all the organs of the air defense base are stationed, the guard battalions that have not yet been fully staffed will also be completely replenished.

Zhang Yuan jumped out of the car, gathered the troops to distribute the work, and with a wave of his hand, the troops were busy unfolding.

At this moment, in the Beiku combat training base, Li Zhan and all the pilots of the Eagle Falcon Brigade were repeatedly familiarizing themselves with the combat plan. There is more than one plan, but multiple plans, and how to deal with any unexpected situations, and so on, all of which everyone must be familiar with.

In addition to the preparation of the air service detachment, Li Zhan undoubtedly paid the most attention to the preparation of the ground service detachment, and the most important thing was the situation of the meteorological detachment. Whether God gives face or not, and how to give it, these are only known to the meteorological detachment.

After the combat meeting, Li Zhan immediately called the Eagle's Nest Field Command Center.

He used wired communications, and used optical fiber cable lines for national defense communications. Highway 4 was laid in parallel with national defense communication lines and buried underground according to the prescribed standards. In order to ensure the smooth communication and confidentiality between the base and the field command center, the higher authorities have activated the wartime communication plan.

That is, it is directly connected to the underground optical cable line and transmitted the signal through the communication station, so as to achieve the purpose of direct contact between the field command center and the base.

If it's an old land, let's honestly let the wired soldiers lay the line in the field.

How about hundreds of kilometers, it still has to be paved.

The army basically has two sets of field communication systems, the wireless communication network and the wired communication system, which have basically been dominated by the wireless communication system to this day, but the construction of the wired communication system has never been abandoned. Anyone who has ever been a communications soldier knows that there are two kinds of communication soldiers, wired soldiers and wireless soldiers, the former is a bitter force, and the latter sits there crackling and playing keyboards.

What is a wired soldier is a soldier who carries a coil on his back from point A to point B to lay it. In the era when there were no wireless troops, the wired soldiers carried coils on their backs and walked in a straight line in the barren mountains and mountains, and tried to take a straight line from point A to point B.

That antagonism scared even the scouts, at least the scouts could choose their own path.

Although science and technology are now developed, but the wired soldiers still exist, the old land is very dirty, their senior generals have always believed that wired communication is more reliable, therefore, the wired communication system as the last means of mobile combat communication in the field has been retained, and has been more developed.

The voice was very clear, and Li Zhan heard Zhang Yuan say, "Old Li, I have not very good news, the probability of a sandstorm tomorrow is sixty percent, and the direction is to the Eagle's Nest." However, the exact timing needs to be further analyzed. ”

"Old comrade-in-arms, you have to hurry up and make sure, if you don't give me time, I don't know when the next step will be. Tomorrow at 0:05 the confrontation drill begins, all information is blocked, I don't know where the Red Army troops have been, whether they have arrived at the bomber division's station or are still on the Gyeonggi stronghold, in any case I must carry out an emergency evacuation as soon as the confrontation drill begins. Li Zhan said eagerly, "It's up to you how this play starts." ”

Zhang Yuan was helpless, and said bitterly, "I said Lao Li, you can't put all the pressure on me, I'm a meteorological engineer, I do forecasting work, and I can't influence the weather!" ”

"I don't want you to affect the weather, I just want to determine the data, if there is a sandstorm, what level, when it starts, the path and speed of the movement, etc., I want to be sure of the data." Li Zhan said in a deep voice.

Zhang Yuan reluctantly explained, "I just received a report from the National Meteorological Observatory today, this weather is coming from the north of the Beiku Mountains, our radar can't see it, only the national meteorological satellite can see its full picture." Anyway, I can't give you the exact data right now, but I'll do it as soon as possible. ”

"Lao Zhang, it's not me who puts pressure on you, it's the Red Army troops who put pressure on us. The energy of this Royal Cat Flying Group is beyond imagination, and too many unexpected situations have happened. The killer feature of the Steering and Dispatch Department has been warned by the Air Division! Li Zhan also has bitterness and can't say it.

In his imagination, no matter how powerful the Red Army unit was, it was not enough to see it, because he had such a strategic weapon of mass destruction as the Command and Dispatch Department in his hands, and he could completely use one command to turn the entire battle around, or two.

However, now the air division has actually issued three documents to the Beiku director in a row, requiring that the confrontation drill be carried out in accordance with the principle of fairness and justice.

There is no doubt that the Royal Cat Flying Regiment has done its job on the side of the air division.
