A few days later, the Iron Wall 17 base, in the secret telecommunications room. The mobile phone has no ads, and it saves the most data.

Zhang Lin sat there in front of several monitors, busy categorizing and sorting out the collected signals, Li Mu stood behind him and watched, and on the other side was An Ruoyi who was constantly searching and tracking unfamiliar signals.

"Boss, in general, detection is the first and most basic step. It is necessary to find out the radio waves, understand the situation of the radio waves, and then analyze their characteristics. Radar signals, satellite base station signals, radio signals, wireless broadcast signals, and even signals emitted by mobile phones, there are a lot of radio waves in the air that we can't see. The source of these radio waves is very complex. Therefore, we usually refer to the existing database for preliminary screening to reduce the workload for subsequent analysis. That's what I'm doing right now. ”

Zhang Lin knew that Li Mu didn't know anything about telecommunications, so he was busy teaching Li Mu a lesson, and there was a little smug in his tone - you Li Motou also had today, so you were so ruthless to us before.

"You can be a little more purposeful. Li Mu said, "All the frequency information that appears at 180 degrees on the front is collected and divided into two categories, military and civilian. What I need you to do is to analyze the military frequency information used, and finally come up with the primary communication frequency and the backup communication frequency used by the other side in the event of a war. ”

Zhang Lin slowly turned around and looked at Li Mu in surprise.

She was surprised, first because Li Mu was by no means ignorant of telecommunications, and secondly, according to what Li Mu said, this was going to war?

"Boss, are you going to war?" Zhang Lin swallowed with difficulty.

Li Mu asked rhetorically, "Isn't the existence of the army just for war?"

The answer is ambiguous, but it also expresses a strong meaning - don't ask what you shouldn't ask.

Zhang Lin tried her best to stabilize her mind, gathered her spirit and continued to work, and her spirit was even better.

"This period is a rare window, and the frequency of communication that does not usually occur will appear, and the amount of communication will be much larger than usual. Therefore, you have to work hard, don't let go of any unfamiliar frequency, and finally come up with a reliable analysis conclusion. Li Mu said in a deep voice.

An Ruoyi, who was also surprised on the other side, nodded heavily.

Zhang Lin and An Ruoyi had already felt it.

Through all kinds of advanced detection equipment installed in the Tiebi 17 base, they can track the specific location of those signals, decipher some simple communication signals, listen to voice signals, and even analyze what kind of communication equipment the other party is using through the characteristics of frequency and band!

These things are obviously in front of them, completely undefended, Zhang Lin and An Ruoyi are not stupid, how can they not guess. But they will not be naïve enough to think that this is a preparation for war, and if such preparations are made before the war begins, it will be too late!

Therefore, there is only one possibility - to take advantage of this rare opportunity to collect a large number of materials, and then analyze them to obtain analysis results that are not usually available.

That's one of the ways intelligence is obtained, and how it works.

The signal light at the door lit up, Li Mu glanced at it, and said to Zhang Lin and An Ruoyi, "Turn off all the equipment and go back to rest." ”

Zhang Lin and An Ruoyi are used to this, as long as the red signal light at the door flashes, they have to turn off all the equipment and enter the standby state, and there is an order to come over, and then continue to work.

Outside the door, Wang Guoqing waited there.

He was responsible for transmitting the information, and the base duty room notified that Wang Guoqing would arrive here within the specified time, press the trigger button outside the door, and the red signal light inside would flash.

Walking towards the control center with Li Mu, Wang Guoqing reported in a low voice, "The latest news is coming over there, we don't have much time." ”

"How much?"

"Ten days at most. ”

Li Mu calculated the progress and nodded slightly, "It's almost." ”

When he arrived at the lounge next to the control center, Wang Guoqing stopped and motioned for Li Mu to go in. The two walked into the lounge, and Wang Guoqing took out a telegram and handed it to Li Mu.

Li Mu took a look at it, his brows couldn't help jumping a few times, and then he smiled, "Military observer, interesting." ”

Wang Guoqing was in a very excited mood, but he was very old-fashioned and would not show his emotions easily, and it was precisely because he was calm enough that Li Mu kept him by his side as a confidential staff officer, even though he was a non-commissioned officer.

"Boss, I'm your confidential counselor, and I'm sure I'm going to follow you. Wang Guoqing said.

What a rare opportunity to go abroad.

"You know, before I joined the 701 Frontier Regiment, I served in the army field unit, and at that time I had just become a non-commissioned officer and participated in the peacekeeping operation in Congo. I have experience. Wang Guoqing said.

Li Mu smiled, "What are you nervous about, I will take you there." ”

Xiao Song also wants to go. Wang Guoqing said, "He was looking for you and was stopped by me." ”

The level of secrecy of the message did not exceed Wang Guoqing's authority, but in fact it was just an ordinary command message, so there was no situation in this regard in which Wang Guoqing privately leaked the contents of the message.

After thinking about it for a while, Li Mu nodded, "Take it with you, it's good to have a long experience." ”

After thinking about it, Li Mu said in a deep voice, "Lao Wang, you have thought about it, I don't think this mission is simple. ”

"Military observer ......" Wang Guoqing suddenly thought of the current situation in Syria, suddenly understood, raised his chin, and said, "Boss, then I have to go." ”

"Well done. ”

Li Mu patted Wang Guoqing's shoulder with satisfaction.

What we want is a soldier who rises to the occasion.

Is it obviously impossible for the headquarters to name Li Mulai as this military observer?

"In the next time, you take Xiao Song to do training, the terrain and landform here are very training, find the guard troops, and do training with them. That part of Syria is full of dangers, so you must be fully prepared. Li Mu said.

Wang Guoqing resolutely said, "Don't worry, boss, I will pull Xiao Song out tomorrow to survive in the wild for a few days." ”

"Be safe. ”

"Yes!"

Before the task of the Tiebi 17th base was completed, the order from the headquarters went directly to Li Mu here, and it was basically certain that the situation on the Syrian side must have undergone some unsatisfactory changes. The United Nations affirms the directive given to a number of countries to send military observers.

The latest news shows that the DIS forces have been beaten to the border by the Iraqi government forces, and it is only a matter of time before they regain all the lost territory.

The decision of the United Nations to send military observers at this time is obviously a last-ditch effort to wipe out the DIS forces in one fell swoop.

In this battle, Li Mu had to participate.
