After the three patrol soldiers left, Lin Rui and Sergei quickly climbed up.

"You're finally back, you're done?" said Shogan in a low voice.

"It's done, what about those U.S. troops?" said Lin Rui as he came up and looked around vigilantly.

Jiang Yan whispered, "I coped with it, it seems that they are just ordinary patrol squads, and there is no suspicion." However, it is not advisable to stay here for long, we must evacuate immediately, and return the maintenance car before the maintenance workers find out. Otherwise, it will cause alarm. ”

Lin Rui nodded, turned around and made a gesture to Sergei, "Go." Sergei nodded, and the two quickly got into the car and left here with Jiangan. When they returned, they secretly returned the vehicle. Returned to the meeting point again.

"What if Cobain is in the situation?" said Shogishi to open the tactical computer channel.

"Everything is working fine, we are starting to crack. We'll let you know when we have news. Cobain replied.

Lin Rui nodded, turned around and said, "Okay, we'll leave the password part to Cobain to deal with." We'll have to think about designing our fake identities. As promised, Yelena, Crystal, you pretend to be a female cadet from the Air Force Academy. Crazy Horse and Sergey, you, along with them, are posing as faculty members of the Academy. You are here for your academic research projects. Sandro, you and I are logistics maintenance personnel of Unit 721. Jiang'an, you are a civilian official of the Ministry of Defense to the Cheyenne Hill base on business.

Snake Eyes, Rose, you lead these three newcomers into the second group, and they are in charge of answering outside. If there is no problem, we need to make a batch of fake identification documents and related documents. Sergey, what do you have to introduce?"

"I do know a group of forgers, but most of them are in Europe. Shogishi frowned.

"I have a way. Sandro raised his hand and said, "I know a few good players, and the documents they make are almost invisible. ”

"Is it reliable?" Lin Rui frowned.

"It's very reliable, these people have been making fake passports for illegal immigrants from South America for many years. As long as there is a model, they can imitate everything. Sandro smiled and said, "Of course, the fake documents made can only be said to be realistic, not real, because there is no chip in it, as long as it is scanned, it will be exposed." ”

"Scanning this part of the Corben will solve it, then the documents will be left to you to solve. Remember, leave no traces. Lin Rui said to him.

"Understand, I know someone who is very reliable. Sandro nodded. "But slow work takes a few days. ”

"No problem, Cobain can't come up with an answer right away. Jiangan, contact Cobain to find a way to invade the above-mentioned units, and send an appointment request, the time is temporarily set five days later. Lin Rui turned around and said, "Don't be idle, continue to read the information, I don't need you all to understand that place thoroughly." But I want you to be familiar with the terrain and know their course of action. ”

"I can almost recite it. Sergei frowned.

"Then memorize it a few more times. I must make it clear that we will not be able to enter the base in advance for this operation, so all the information inside the base can only be obtained from the information available. That's the real reason I'm getting you acquainted with the material. In any operation, unfamiliarity with the terrain is the biggest taboo. Especially now that we are dealing with a difficult bone to gnaw. Lin Rui said in a deep voice, "Do you have any questions?"

"Okay, okay. I'm just talking about it casually, to be honest, boss, so much information will make people's heads look big. Sergei said with a sigh.

"As long as it is useful for the task, what should be mastered must be mastered. Lin Rui shook his head and said, "Since you said it, you are already familiar with it." Then I'll ask you. How many guards are there on the perimeter?"

"There were more than a hundred people in total, of which the guards at the tunnel gate were the most, more than fifty-two, and the rest were in charge of other positions. Sergey replied. Lin Rui shook his head and said, "The answer is not complete. A total of one hundred and thirty-eight guards were guarded, fifty-two at the tunnel gate, and the rest were scattered in twenty-six positions. The rest of the people take turns resting, and they are no more than two kilometers apart at the farthest. In other words, they can support each other if something happens. You should have seen their course of action and know how they acted?"

"I know, the internal security personnel, when alerted, will quickly assemble. Then support the periphery. Sergey replied.

"What was the time from the time they received the alert to the time when they launched the support?" Lin Rui then asked.

Sergei frowned, "This doesn't seem to be available in the information." ”

"There is a document, but you didn't look at it carefully. Let's start with the map, this is their rest area, and this is the weapons room of the garrison. The distance is marked on the drawing. In the event of an alarm, they must run to the weapons room and equip themselves all up. Then assemble and rush to the alarm point. This distance is also marked on the electronic map. In the case of generally well-trained troops, it takes at least three and a half minutes for them to run the whole journey from the assembly to the main gate for support. Lin Rui smiled.

"Well, I didn't think about it that much. Sergei said helplessly.

"So how much do you know about their armament?" Lin Rui said as he looked at Sergei.

"M4 type 5.56 mm carbine, and M9 pistol, and of course some tactical grenades. The others are body armor and helmets and things like that. Sergei frowned.

Lin Rui shook his head and said, "Again, it's only partially right, they also have the M60E3 7.62mm general-purpose machine gun in their arsenal. In addition, their equipment is very advanced.

They are equipped with the LA-8 / P finger-type laser friend or foe recognizer for identification of friend or foe in the night special operation. There are also enhanced night vision goggles, a helmet-mounted night vision goggle for individual soldiers that combines image enhancement technology with infrared thermal imaging technology. It serves as a secondary equipment for them to fight in dark environments such as tunnels.

In their tank there are three "Stryker" wheeled armored vehicles, capable of quickly reaching anywhere, and with clever maneuvers they can complete the encirclement and destruction of targets. All can be done in a tunnel without lights, entirely through the use of night vision gear. ”

Sergei was stunned and said, "So what?"

"So we have to avoid fighting in the dark, and we have to have a strategy to play to our strengths and avoid our weaknesses. If you read all the materials. Lin Rui shook his head and said, "I'm trying to gnaw on these English materials that I am not good at in order to let you survive in the mission." I only hope that you will take this mission seriously for the same reasons. ”

"But, after all, this is just a drill. Crazy Horse frowned.

"I know, it's a drill for the Yankees, but it's a mission for us, and we're all about any mission. Or do you think we can lose to those self-righteous American GIs?" said Lin Rui with a shrug.

Sergei didn't say a word, squatted down and carefully studied the information.
