In the command room of NORAD, Commander Herbert was already personally seated. For this exercise, he had ordered all units to defend to the death, and he did not believe that this mercenary team would break through the outer defenses of the underground base of Cheyenne Mountain head-on. But that's what the other party did, which made Herbert very uncomfortable, and he didn't like it.

As a commander, he has a very strong desire to control, he likes things to go his way, and he doesn't like things that are unexpected. When things go wrong, there must be demons. The opponent's use of a frontal attack in the face of a huge disparity in strength does not conform to normal logic. Unless the commander on the opposite side is a madman. Only then will a dozen people be used to storm a large underground anti-nuclear base with several thousand people working at the same time.

So Herbert sat with some restlessness, and a hint of doubt flashed in his eyes. While looking at the base's defense deployment drawings, he kept asking for a timely report on the battle situation. "Second Lieutenant Parker, I need information on the engagement at the entrance to the frontal tunnel. The number of opponents, the situation of fire. Troop casualties. ”

"Report to the general, at the moment there are not many casualties on our side, the other side seems to be very fierce, but they don't know for what reason, they have been setting off smoke bombs. Perhaps because of this, visibility is too low. Reduced their offensive efficiency.

However, we suspect that this was premeditated, and perhaps the smoke grenades contained biochemical agents. I've put the soldiers in gas masks, and I've activated the ventilation and exhaust facilities to protect against biological and chemical attacks, and they can't get in for the time being. The lieutenant replied.

"Well, be on guard, guard the entrance, and don't let them break in. Herbert shook his head. "Other departments must also be on guard to prevent infiltration and surprise attacks by armed men from the other side. ”

"I've given the order, sir. "The door to the command opened, and a colonel walked in. He was the commander of the guard unit here, Colonel Max. In fact, he is responsible for all the actual security around him.

Herbert breathed a sigh of relief when he came, "It's good to have you here, Colonel Max." How's it going?"

"It looks like everything is under control. The gang was barricaded at the door. It won't be long before our reinforcements arrive, and they will be blocked at the entrance and annihilated in one fell swoop. Unless they can open the gate within ten points. In fact, I have ordered that most of the guards have been withdrawn and the base gates have been closed, except for a small number of guards to hold them back. Those attackers could get in if they wanted to, unless they could blow open a twenty-five ton nuclear-proof metal door. Colonel Max smiled.

General Herbert smiled and said, "Great, well done." ”

Colonel Max shook his head and said, "If only it were that simple, I actually found a little anomaly just now. The monitoring equipment in the upper infirmary was ineffective for about two to three minutes. It may seem like a common distraction, but it's a bit too much of a coincidence. Especially when I found out that after two or three minutes the elevator there was suddenly activated. ”

"Oh?" General Herbert's eyes froze. "What's going on?"

"The system shows that the authorized user is one of our paramedics. But according to the arrangement, he should be on duty at the top and should not have come down from the medical elevator without notice. If these are just coincidences, then there is one more coincidence. The surveillance inside the elevator is broken. Colonel Max said slowly.

Herbert's face became very ugly, and he said in a deep voice, "What do you think?"

"They've had someone infiltrate the base, and smartly, but boldly, through the tunnel, into the upper infirmary. Then from the infirmary, you will be taken to the medical center below via a medical elevator. Very thoughtful. Max was an understatement.

"Looks like you've got the arrangement. Herbert's face softened slightly.

"I had two platoons of troops at the elevator entrance of the medical center. As soon as the elevator opens, as soon as they step out, there will be a relentless rain of bullets waiting for them. Colonel Max nodded, "I'm just here to ask if you should stay alive?"

"Damn it, Max, you're a genius. Herbert laughed.

"It's just a bunch of mercenaries, I think I can handle it. Colonel Max smiled.

"There shouldn't be many of them, fix them well. Herb nodded. "Let this guy know what it costs to offend us. ”

"Don't worry, sir, I'll bring them to you. Max turned and strode out.

At the elevator entrance of the medical center, a group of American soldiers had formed a formation in layers, squatting or standing, staring nervously at the elevator door. In order to enhance protection, the American soldiers on both wings even introduced heavy bulletproof shields. This is not a light shield for anti-pistols, but a real level 6 protective shield that can effectively block 7.62mm automatic rifles.

Because of the high level of protection, it is also extremely heavy. So it could not be hand-held, but wheels were installed under the shield and pushed out like a movable screen. Because the elevator exit is facing the passage, in order to increase protection, the U.S. military deliberately set up this bulletproof shield on both sides to enhance protection. Avoid fighting when you fall, without even a little cover.

Colonel Max looked at him coldly. "How much longer?"

"Arrive in twenty seconds, and the door will open two seconds after arriving. A U.S. soldier replied.

"Ready!" Colonel Max looked at his watch and raised his hand.

The elevator doors slowly opened, and the American soldiers raised their guns sharply, but none of them fired. Because there was no one in the elevator. Colonel Max's face changed dramatically, and he rushed up to take a look, and found that a maintenance opening at the top of the elevator had been opened.

Colonel Max exclaimed, "Damn, they ran ahead of time. We need to cordon off the entire health care building. They could be anywhere, so search carefully and don't give up on every corner. ”

In an instant, the underground-built medical building was in chaos, and the U.S. troops were divided into squads, each inspecting the area they were responsible for. The sound of noisy footsteps mingled with the sound of their gear colliding. Everyone's faces were heavy, for they had never seen the Colonel make such a big fire.

There was only one US military team, they were Lin Rui and others wearing the uniforms of the US military, and they also pretended to be in a hurry and trotted by.

"Boss, how did you guess that they would set up an ambush at the elevator entrance?" Sergey couldn't help but whisper.

"Because if it's me, I'll do the same. And they would never have imagined that we would change our whereabouts and climb out of the elevator on the upper floor. And when they find out that we are not there, they will definitely suspect that we are in the upper echelons, so they will definitely send someone to check. We can easily fool them by pretending to be searching and checking. They waited for the rabbit, so we gave him a cunning rabbit hole, and let them pounce on the air, and they had to run after us. Lin Rui said in a low voice. "Don't talk, they're coming. ”
