In the afternoon, the command room of the o2 squad of the Black Island Military Company, Saint Kaiser Island, Africa.

Lin Rui and others have received the intelligence from Kobain, almost everything about the Cheyenne Mountain Underground Monitoring Center and North American Air Defense Command. The data includes two parts and one part is a large number of picture materials such as building topography. The other part is personnel information and facility information.

"From these data, this base is quite solid. The monitoring center has more than 200 networks composed of super large, large, and medium computers and more than 600 dedicated communication lines. The center uses communication satellites, microwave relay lines and optical cables. Various communication tools exchange information with the outside world.

It can receive data from various detection and monitoring methods such as military satellite systems, civil satellite systems, air early warning networks and ground early warning networks; it also communicates with the Pentagon, the White House, and the U.S. Strategic Command through a backup and strong hotline. , The Canadian Armed Forces Command and major U.S. military bases scattered around the world maintain close contact.

The monitoring center has more than 1,200 military and civilian personnel. The building is lit up 24 hours a day and night throughout the year, with constant telephone calls, non-stop telex, and screens. The staff is on duty day and night, monitoring thousands of man-made objects orbiting the earth in space, and alerting to sudden attacks on North America and overseas bases in the United States from land, sea, air or space.

All monitoring and security tasks of the Cheyenne Mountain Underground Monitoring Center are shared by 7 departments. They are the aviation alert center, missile alert center, space control center, integrated intelligence monitoring center, system center, meteorological support center, and command center. This is a veritable command center for the US military.

In addition to these, they also have a 900-person logistics support team, code-named 721, consisting of 4 small teams.

The 721 civil engineering team is responsible for property management and maintenance, power system and environmental control system operation and maintenance, fire prevention and snow removal tasks;

The 721 communication unit is responsible for the operation, maintenance and repair of all computer systems and communication lines;

The 721 security team is responsible for physical, industrial and information security, access management, transportation, and visit control. "

"Then we have to deal with the 721 security team?" Sergey nodded.

"Yes. According to the information provided by Cobain, this security unit is very professional and capable and very reliable. Once we enter this base, they will be our main enemy. The head of the security department is Colonel Joseph, who used to be the Army Of the elite.

Served in the 101st Air Assault Division and participated in the Afghanistan War and the Iraq War. The year before, he was transferred to the Xia Yanshan Underground Monitoring Center as the head of security. The security forces under him are all experienced members of the security forces. "Jian An replied.

"It's not very useful." Sergey shook his head.

"You can't say that. Compared to the average U.S. military, they are still quite powerful. And they are much more familiar with the terrain inside the base than we are." Lin Rui shook his head and said, "You can't underestimate them."

"Is there a plan on how to sneak in?" Crazy Horse frowned, "This kind of test will not let us drive a tank to attack?"

"Even tanks can't open the gates of underground fortifications. People are protected against nuclear weapons. So the storm is a joke." Lin Rui shook his head, "I think we still have to rely on Cobain. If he can successfully invade the opponent's computer system , Then we can enter with forged identity information. At least a few passes before entering the base are not a problem."

"How many levels were before entering?" Sergey frowned.

"Yes, the personnel on duty will first verify the authenticity of the identity, then check whether there is an appointment, and may ask some questions. Then they will verify the password and the identity card. These identity cards can read the information, and the authenticity of the Ben controls the computer and can make fakes and consider the fakes to be real. We can get in smoothly." Jiang An replied.

"But what if Cobain fails?" Crazy Horse frowned.

"Then we can only think of other methods. But IMHO, the risk of other methods is much higher than this." Jiang Jian shook his head.

Lin Rui nodded, "It is true that it would be difficult for us to do it without Cobain's assistance, but Crazy Horse's worries are not unreasonable. We can't put all the bets on Ke itself. In case of accidents, we still have to. Other ways of coping."

"That's what I mean." Sergey nodded, "Perhaps we should think of other ways to enter. Generally speaking, this base will have other exits. For example, in the event of a fire or other disaster, their personnel Shouldn't there be other evacuation channels?"

"You think too much, at least according to the drawings, there are no other exits at all. What you said is that if there is a fire or something, they do have evacuation channels, but they do not evacuate to the ground, but evacuate to other areas underground.

This is a huge underground facility with complete facilities. It is completely different from those underground bases we encountered before. Below is almost an underground town, the passage can enter and exit large trucks. There is no need to consider the issue of diversion at all. "Jiang An shook his head.

"Ventilation facilities, such a huge facility must have ventilation facilities, maybe we can sneak in from there." Sergey frowned.

"This is also impossible. Taking into account the danger of nuclear bladder attack, their ventilation ducts are of special honeycomb design. There are dozens of fans operating in various underground areas to ensure air circulation. We cannot pass through. These passages. Unless you can turn into a mouse or a cockroach." Jiang Jian shook his head.

"What about electrical and communication pipes? Or water supply pipes." Sergey said unwillingly, "There is always a channel connecting the outside and the inside?"

"We can't pass the electrical and communication pipelines. They don't have water supply channels at all, because there is a large reservoir in the cave. A large amount of high-quality groundwater is enough to supply thousands of people in this base." Lin Rui only Can smile bitterly.

"Damn, is there really no other way to sneak in?" Sergey frowned, "How about digging a tunnel?"

"Well, maybe you can dig a tunnel in, but there are very hard rock formations. The Americans built a base under the 500-meter-thick rock formation to prevent nuclear bomb attacks. If you want to dig through this tunnel, you have to find one. A construction team will help you do this. And it will take several years." Jiang An shook his head.

"Damn it." Sergey shook his head.
