The building was an ordinary three-story building, and like all military buildings in the former Soviet Union, it was structurally sturdy and stiff-styled. Glancing upward, Lin Ruitong whispered to Ah Hu, a member of the team who was watching from the periphery, "Ah Hu, help me see the situation on the three-story building opposite the main gate of the fortress." ”

"Three people, all with weapons. There was also an anti-aircraft anti-aircraft gun, which was too far away to see the model clearly. Ah Hu whispered back, "Their locations are in the southeast corner, due south and west. In terms of the height of the building, the roof can be clearly seen except for the sniper tower on the west side. ”

"Roger. Lin Rui nodded, cut off the communication, and turned to Chen Nanqingdao, "It's similar to what I thought." Because of the orientation of the house, their main defensive range is the side facing the gate. That is, there is emptiness behind them. ”

Chen Nanqing smiled and said, "Then, let's teach them to keep an eye on their backs." ”

Lin Rui nodded to Chen Nanqing, put the weapon behind his back, ran a few steps, jumped up, and used the stacks and pipes of the house to climb up with his bare hands.

Lin Rui silently climbed to the top of the building, revealing half of his head and taking a quick look at the situation on the roof. Upstairs, there are a total of three mercenaries, guarded on three sides. The point is to monitor the position of the fortress gates and sides.

Lin Rui turned over and squatted on one side carefully, and then Chen Nanqing also came up. Both men were very careful to hold their breath and not make a single sound. And the attention of the three mercenaries was all in front of them, and they didn't notice that two people had climbed up behind them. While looking at the three mercenaries, Lin Rui couldn't help frowning. If the positions of these three mercenaries were brought closer, he and Chen Nanqing would be sure to deal with them without any sound.

However, now, even if Lin Rui and Chen Nanqing do it separately and subdue a mercenary each, then the rest of them will definitely be aware of it. However, because of the distance, they can't reach the whip of this remaining mercenary. It was too difficult to kill three people silently, and they had to do it. The first rule of infiltration is to do everything possible and not expose yourself.

Lin Rui turned his head and glanced at Chen Nanqing, pointed to his eyes, and made a direction gesture again. Meaning that he was responsible for taking out the mercenary in the southeast corner. Chen Nanqing nodded silently and slowly touched to the side. And Lin Rui also pulled out the military dagger with his backhand and walked to the other side.

The sun at noon is a little warm, especially in this spring season, and the sun shines on people's bodies, making people lazy and unable to lift up. Those mercenaries too, compared to other posts, they are idle here. Sit upstairs basking in the sun, blowing the wind, and leisurely smoking a few cigarettes. But it's the sun that makes people a little sleepy.

One of the mercenaries stretched lazily and was about to get up and take two steps to move. A hand had reached behind him and covered his mouth, and almost at the same time, the cold blade had sliced open his throat. A powerful hand, a fast, accurate, and ruthless knife.

A large amount of blood spread down the airway, completely blocking his trachea, he couldn't make a sound, he didn't even feel much pain, he just felt a little suffocated. The suffocation made him kick his legs and whip his feet weakly. The movement alarmed the other mercenary, who had already turned around alertly.

Lin Rui felt helpless in his heart, and pushed away the mercenary who was still struggling after his throat was cut. A fish leaped to the side, and almost at the same time, the startled mercenary had already raised his gun and opened fire. The dust and sparks kicked off by the bullets on the concrete made Lin Rui feel a little disappointed. Despite all the caution, it was exposed.

He rolled over and rolled into the mercenary's shooting corner, and was about to raise his gun to return fire. Suddenly, a dull gunshot was heard in the distance, and the mercenary was hit by the huge impact of the bullet, and a cloud of blood mist burst out of his chest, and he spun around like a spinning top before falling. His body presented horrific wounds, and one of his arms had been completely torn apart.

Lin Rui knew that this was caused by the anti-materiel sniper rifle, and he sighed and gave a thumbs up to the sniper tower in the distance. On the sniper tower, Peng Lefeng was still holding the heavy and cold long-range weapon.

Chen Nanqing has also dealt with another mercenary. But it's too late, they're completely exposed. The mournful sirens of the military fortress resounded in the sky. The entire fortress has been fully brought into combat condition, and all personnel have already entered combat positions. There were footsteps everywhere, and Gross's men were emerging from various positions in the fortress.

Chen Nanqing said helplessly, "What now?"

"It's fine. The goal of infiltration is to strike, and sooner or later it will be exposed. Lin Rui shook his head and said, "It's just a little ahead now, but we have to step up." Help me guard the entrance to the hallway, and give me at least five minutes. ”

Chen Nanqing nodded, pushed down the eyepiece on his helmet, and raised his gun to guard the corridor.

Lin Rui walked in front of the ZPU23 anti-aircraft gun, looked at the ammunition, and then sat down.

After all, the local mercenary team of Gross was well-trained, and after the alarm sounded, it only went through a short period of panic and adjustment, and immediately entered the state. The guards at the main gate of the fortress had already entered the combat position, but what made them a little puzzled was that the gunfire just now seemed to be coming from behind them. Soon their doubts were answered, and the anti-aircraft gun on the roof behind them began to fire flatly.

23 mm caliber ammunition, like a metal rainstorm, poured down from the opposite building. The ZPU23 double-barreled anti-aircraft gun was equipped with a flame suppression device, but even this spewed out flames that were a meter long. Under the development of modern aircraft technology, this ZPU23 anti-aircraft gun for low-altitude defense has long lost its air superiority, and is more used in combat against the enemy.

In the Libyan civil war in 2011, many of these anti-aircraft guns were mounted on Nissan, Toyota, ZTE, and Great Wall pickups. During the war, the Libyan opposition also "invented" a unique "tactic" -- two pickup trucks were equipped with ZPU-23 antiaircraft guns or antiaircraft machine guns in their bodies, and the rear of the trucks fired alternately at the enemy while reversing.

The rumbling sound of ZPU-23 anti-aircraft gun fire officially pushed a stealth operation to the height of a head-on firefight. The defense of the main entrance of the fortress was riddled with holes by this twin anti-aircraft cannon. Under the intensive blow of artillery fire, the thick concrete building kicked up clouds of dust, and large pieces of concrete fell off, revealing the internal steel skeleton, not to mention the flesh and blood. Under the attack of this 23 mm caliber high-explosive ammunition, the human body is as weak as tender tofu.

Many of the mercenaries guarding the main gate didn't even have time to raise their heads before they were shot into pulp by the rain of metal bullets. Lin Rui's feet "ping pong" sprinkled a bunch of bullet casings, and the defense of the main gate also completely collapsed under the destruction of this heavy firepower.

"Da ......" Chen Nanqing was guarding the entrance of the corridor, and he had already exchanged fire with the mercenaries. "Xiao Lin, is it over?" he shouted back.

"It's almost over. Lin Rui jumped down from the operation position of the anti-aircraft gun, walked quickly to the door, and connected the wireless communication in an orderly manner, "The operation code is thunder, and the identification code is 452284406." I am Lin Rui of the fifth squad, and the defense of the main gate has been destroyed. I repeat, the main gate defense has been destroyed, and the second objective has been achieved. Request instructions for what to do next. ”

"Got it, we're already organizing a assault. Lin Rui did a nice job, but be careful, try to survive before we arrive. Tang Kun's voice replied.

"Roger, done. Lin Rui didn't stop while talking, and a long shot knocked down a mercenary who was trying to rush up.

Chen Nanqing said nervously, "Okay, it's almost time for us to withdraw." It's not the way to do it. He threw a grenade at the mercenary downstairs, and the grenade rolled down the stairs of the stairs, exploding a mist of blood in the crowd.

Lin Rui nodded and said, "It's time to go, but there is one more thing to do." We have to have a beginning and an end. He took out one of the remaining C4 bombs and placed it in the doorway to the roof, quickly setting the time-delay fuse. Then with a look at Chen Nanqing, the two quickly walked to the edge of the building, hung the rope lock around their waists on the guardrail of the building, and began to land from the roof.

Just as they stepped on the ground, a shocking explosion sounded from the roof behind them. The impact of the explosion caused the two of them to nearly lose their balance and fall to the ground. Chen Nanqing raised his head and said with a wry smile, "This is really exciting." ”

"If you don't run away, there will be more excitement. Lin Rui pulled him up from the ground and ran as hard as he could. The gunfire was heavy behind him, and the remaining mercenaries caught up again. Lin Rui connected to Qin Fen and Peng Lefeng's communication channel while running, "How is it? Are they all alive?"

"Alive, and alive and well. Qin Fen replied.

"I'm still alive, and after saying that, I don't know. I'm going to evacuate the sniper tower, and my location was exposed. Peng Lefeng said in a low voice.

Lin Rui nodded, "Okay, if possible, try to evacuate." If you can't get out, try your best to survive. Our mission here is accomplished. Now it's up to everyone else. ”

In the command room of the fortress, Gross was furious, "What the hell is going on?

"It's not clear how many people there are, but it doesn't look like they're a lot, it's probably just a squad, maybe two. They took control of an anti-aircraft gun behind the main entrance, which had already completely destroyed most of our defenses in the front. On the west side, we were also sniped by unknown persons, the number of whom is not yet known. The preliminary judgment is that these people should be just an infiltration team. The mercenary on the radio responded.

"Damn, how the hell did they get in?!" Gross said angrily, "Find these rats for me!" ”
