In Khamba's house, the remaining three people were on guard all night. They don't know what mission Yang is not hungry and the veterinarian is going to perform, but it is necessary to prepare for the worst.

When the sky lit up, there was finally a gentle knock on the door. As soon as Yao Bing opened the door, he saw Yang Bu coming in with a grin, only carrying a communication phone in his hand. The veterinarian followed behind and spread his hands in the face of everyone's inquiring eyes.

"Don't you say you came back with this thing after a night of tossing?"

After handing the two people a glass of water, the knife pointed to the communication phone on the table and couldn't help but complain.

The veterinarian didn't care about this, he just went to get soy sauce, and even he was waiting for Yang Buxing's explanation.

"Don't worry, I'll tell you after I've finished drinking this sip of water. ”

Yang Bu was hungry and filled his cup with water, and then drank it all in one go.

"First of all, we know that the communication signals used in this exercise area are not satellite signals.

In order to increase the difficulty, every time the director department except for the Beidou positioning navigator, any communication must be completed through the communication vehicle command vehicle or the construction of a base station antenna, which can also serve the purpose of training the communication troops.

However, when it comes to building a base station, or erecting an antenna, this involves a communication password. Of course, setting up these communication passwords is the work of the communication link.

For example, in the forward positions of the enemy troops that were captured just yesterday, of course, the communication telephones will also be captured, but as long as the communication company changes the communication passwords except for the captured communication phones, then our side cannot use those captured communication phones to reverse decryption and surveillance.

And if we want to cause some trouble for the enemy's communication company, I really can't think of any effective way to do it other than to use this communication phone.

5 people killed the communication company of more than 100 people, and they are still behind the enemy, and there are snow leopards staring at them all the time, anyway, I don't have the ability. ”

"Then you have a fart to get this, first of all, everyone has only learned a scratch about this code breaking, if you give me Lao Yao another year and a half, it may be possible.

Besides, as soon as people find out that their communication phone is lost, they change their passwords again, which is not in vain. ”

Fiddling with the phone in his hand, Yao Bing voiced his doubts.

"I know, is it going to replace the enemy's backup communication phone with this communication phone next!"

The veterinarian immediately reacted that these communication phones were all in a uniform style. Take this stolen from the border post and replace it with the enemy's, then you will be able to know it. But what can this be? It doesn't seem to be of much use, can you still pretend that the other party's leader gives orders to the troops?

"Yes, the next step is to swap the phone number. ”

After confirming the veterinarian's guess, Yang was not hungry and continued:

"As mentioned earlier, the enemy army is equipped with antennas or other equipment on top of the civilian transmission tower to carry out signal communication. What if we connected this phone number directly?"

"Damn, that's too bad. It's not like a phone line. In the case of the same password, as long as we are on the same channel, it is possible to receive messages from the other party, or send our voice through the communication phone, and the other party does not know that it is coming from the communication phone.

And it's useless to change the password, and we also change the communication phone in our hands......"

"From these words, I know that you don't listen well when the instructor is usually explaining, if it's so easy, then why do you need a communication company. There may be automatic frequency hopping set up here, and you want to listen to the enemy's deployment, don't even think about it. At most, it can only create a little noise of interference, and only when there is an overlap of more than 16 channels will there be a 3 to 4 second blank area to transmit the sound, but the odds of this are even lower than winning the lottery. How many numbers are there in this lottery?"

Xiao Fan was still thinking about it, but he was splashed with cold water by Yang Buying.

"After talking for a long time, it turns out that the fart is useless. It's better to go directly to the snow leopard to fight each other. ”

Yao Bing directly threw the communication phone in his hand and returned it to Yang Buxing, this exercise has been going on for so long, and he has not even made any achievements so far, and this face is really unbearable.

"Why is it useless, do you need to troubleshoot this signal problem, this range is so wide, so many signal towers have to be checked. There are only a few people in this communication company, and once a large-scale investigation is needed, how many people do you say are left in this camp? When the time comes, we will end the central control system, and what can the communication company do without equipment?"

Turning the tiger away from the mountain, it turns out that this is the ultimate goal of Yang Buxing. Wait for the end of the central control system, when the time comes, the signal tower will see a tender one, even if they repair it, they can't even debug it.

"Don't rejoice too soon, there are two problems here. The first is how to change the alternate communication phone in the opponent's hand without realizing it, which means that you have to break back into the enemy camp.

The second is to determine the location of the communication link first. The degree of protection of a special communications company directly under such a brigade headquarters is second only to that of the general headquarters. ”

"Will it be put directly with the brigade command?"

The question Xiao Fan asked was exactly what everyone was worried about. If this is the case, the difficulty coefficient will be directly multiplied several times.

"Probably not, with this kind of signal building, the attendance rate is too high, which will greatly increase the exposure of the headquarters, so it should be camped independently. ”

In fact, Yang Bu is not hungry and has no bottom in his heart, but at present, he can only carry out the plan like this......

Located near the southern foothills of the Himalayas, it has a subtropical montane semi-temperate climate. That's why there are large areas of primeval forest growing here. And in the gentle area at the edge of the forest, dozens of camouflage military tents have been artificially erected. Judging by the large red cross sign in the center of the tent, it is clear that this is the logistics field hospital of the "enemy army".

If you want to say that the most leisurely thing in each exercise is this field hospital. Some trivial injuries that occurred in the troops were handled by their own medical personnel, and as for major exercise accidents, they were all directly sent to the hospital. So the field hospital has almost nothing to do except for the necessary training every day.

During the exercise, almost no one would take the initiative to attack such a target of no military value, so that in wartime, it is necessary to have at least one reinforced company to protect the field hospital, and it would be good to have a platoon stationed during the exercise.

"Being stationed in this field hospital is indeed a beautiful errand, not to mention the beautiful nurses, and every day is very leisurely. But the most unbearable thing is not to smoke. ”

"Stop talking, you're going to criticize you by name again. ”

At this time, the two sentries in front of the camp gate were grumbling while patrolling. It's patrolling in the dark, and if you can smoke a cigarette, it's really a good thing to beat the cold and refresh your mind. Perhaps this kind of good thing can be seen everywhere else, but in this field hospital, the first rule is to smoke within 50 meters of the camp. Such a regulation has suffocated the tobacco worms in the stomachs of these old smokers.

The huge camp had more than twenty large tents, and a few smaller ones. In addition to four of them, where doctors and nurses lived, two were garrisons for the soldiers stationed there, while the rest were wounded areas. But now there are no wounded in this ward, it is empty, and the only figure is this patrol in pairs.

In the dark, the tents near the edge of the woods emitted a faint green smoke. And the smoke is not noticeable in the dark night. By the time the flames began to penetrate the tent, the fire could no longer be contained and began to spread.

"Oh no! There is an enemy attack, hurry up and raise the alarm!"

As soon as the light of the fire came out of the tent, the two soldiers on patrol had already blown their whistles to sound the alarm. At this time, everyone woke up from their sleep, and as soon as they came out of the tent, they saw a large fire behind them.

Of course, the first thing that came to mind for the platoon commander was an enemy attack. All the soldiers immediately scattered their positions in search of potential enemies.

But after a long investigation, there was not even a shadow of the enemy, let alone the sound of gunfire. After wasting these ten minutes, the fire has become out of control, and only then did the platoon commander react, this is impossible for the enemy to attack, because this is a field hospital and has no military value at all in the exercise, who will be idle and sore to sneak attack here, and use such a damage trick as arson, so he is not afraid to set this forest on fire. So there is a high probability that this is a fire caused by careless use of fire.

So under the order of this platoon commander, all the soldiers rushed over to extinguish the fire, and even the medical staff in the hospital went to help. Fortunately, there was no wind this night, otherwise the company would have to be burned down, and there was nothing in these tents, only a symbolic bed or two, and there was nothing to burn. But one of them is stacked with ventilators and oxygen cylinders, and it looks like it is about to spread, which can scare the platoon commander a lot and arrange all the personnel to go over.

While everyone was busy putting out the fire, several other black shadows sneaked into the camp, and then scattered into the lighted tent to look for it.

To say that this god unknowingly changed the enemy's communication phone is easier said than done. As long as there is the slightest bit of unusualness, when the communication signal cannot find out the cause of the interference by something, someone will definitely think of this unusual point.

So Yang Bu was hungry and thought about it for a long time, and finally set his goal on this field hospital. It is also the only place where the hinterland of the "enemy army" is most laxly defended. And here, as a complete combat unit at the battalion level, of course, there will also be a backup communication telephone, so there is also this fire.

There were only a few lit tents in total, and Yang Bu was hungry and chose a smaller tent on the left. To his surprise, this was actually a single room, which indirectly showed that the people living in this tent were not of a small level. Soon, this was confirmed by a specially shaped work card pressed against several books on the desk.

"Li Rushan, he looks very handsome, he is already a doctor at such a young age. ”

He was wondering why a doctor of biological genetics would appear in the field hospital for this exercise, when he suddenly noticed that someone had returned at the door.

Yang Bu was not hungry and immediately went under the military bed, and now there was only one place in this tent to hide.

I saw that the person who came was wearing a white coat and a mask, and after looking left and right for a while, he took out a pack of powder from his pocket and poured it into the thermos cup on the desk, shook it a few times and left quickly, the whole process took less than 10 seconds.

"Poison!"

Yang Bu was not hungry, and he would never have thought that he would see such an unbelievable thing in this army. It's a pity that I can't see the face of the person who came and I have a mission, otherwise I would have to find out this person.

Now is not a good time, Yang Buxing quickly got out from under the bed, tore off a page and wrote:

Someone harms you, the water is poisonous, and the wolf tooth Yang is not hungry and leaves a word.

After pressing the note under the thermos cup, he happened to hear Yao Bing's retreat signal outside, so Yang Bu was not hungry and did not hesitate any longer, and quickly replaced the spare communication phone behind the desk and quickly evacuated......
