When the ICBM is launched, the liquid fuel of the Minuteman III will be ignited by the rocket engine, and then a huge thrust will be generated, and the heavy projectile body will be shot out of the silos, which means that at the bottom of the silos, not only do you need a strong, high-temperature resistant bracket and ground, but also build an additional circle of vent valves, so as not to cause the flames to go nowhere, forming a recoil phenomenon in the well, and damaging the body of the Militia III.

The three of them came here specially to pass through these vent valves, which were only more than half a meter high, and go directly from the top floor of 1024 to the bottom of the base, and then flank the operation center of the base from below.

"How's it going? there's nothing wrong with our drawings, right?" Listening to the sound of gunfire faintly echoing in the missile shaft, the wooden handle could imagine how fierce the frontal battle on the undead's side was, so he asked eagerly.

"Later, there were probably some renovations, but the main structure has not changed, and our plan can still be implemented. The Demoman is holding the sonic device to the iron door at this time, so that it can be used to detect the space and structure behind the door, and to confirm whether the drawings in the hands of the undead team are real and valid.

"Great, so what are you waiting for? Hurry up and blow open this damn door, so we can go to their aids. The eager wooden handle hurriedly said.

"Don't be in a hurry, I need to look for weak spots on the door and blast them with a minimum amount of explosives. ”

"Is it necessary to make such trouble?"

“…… Have you forgotten what's behind us?"

Immediately afterwards, when he subconsciously looked back at the wooden handle, he happened to see the huge rocket engine exhaust hole of Militia 3 at the level of his line of sight, and the result was naturally immediately speechless, but the demoman who refused to give up easily still squatted there and said: "You may not believe it, but the shell of Militia 3's projectile body is very thin, and any exploding spark flies up, and we may fly into the sky together." ”

"Really...... Is it so dangerous?" asked the wooden handle, a little unconvinced, and couldn't help but reach out and touch the cold shell of Militia Three.

"Hmph, even if the blasting does not affect the missile body, but if it damages the control system of the vent valve and causes it to not open normally for a while, then we don't want to launch this intercontinental missile, because before the thrust sends the missile body, the launch flame that has nowhere to excrete will swallow the missile and form the most dangerous cavity explosion. ”

Seeing that the Demoman was talking so badly, he finally stopped arguing, and in his impatience, he simply took two steps back and began to carry his AR15 far away so that the Demoman could concentrate on his work.

After about 2-3 minutes, the Demoman, with the assistance of the civil expert, slowly extended the crumpled plastic explosive into the small hole that had just been drilled by the electric drill, and probed deep into the inner vent of the valve, and finally waited for the Demoman to carefully connect the detonation device, and then he breathed a sigh of relief, and waved his hand to the wooden handle and the civil engineer to quickly find a place to hide.

Later, when the Demoman dragged the detonator line behind them, he pressed the button suddenly, and in an instant he saw a flash of fire and smoke in the small holes drilled out of the deflating door, and there was a tooth-inducing cracking sound of metal.

Before the smoke in front of the deflator had cleared, the Demoman hurried over, thrust the drill of an electric drill into the blackened hole, and then flicked it so hard to the side that the deflector made a "creaking" grinding sound, and then little by little it was pushed open by the Demoman and the civil engineer.

He is really an expert in playing with explosives, although he can also perform small operations such as M24 charging and modification, but he still admires the ability of the demoman very much, and he really used the least amount of explosives, destroying the internal structure of the vent valve, making the locking mechanism ineffective, and not causing any damage to the surrounding area.

Next, following the vent door, which was not much bigger than the dog hole, the three of them left the first missile shaft, and after entering the area on the bottom floor of 1024, the demoman and the civil engineer were back to work, and now they only had to take down a sealed door, and they could reach Captain Frank directly below their operations center.

But just as the three of them approached step by step, in the corridor outside the door of the combat center, the big iron gate of the undead team finally moved to within 15 meters.

At this moment, not only the garrison soldiers under Lieutenant Niu Wen, but even those civilian soldiers also clenched their weapons one after another, ready to fight to the death with the enemy, but in the suffocating atmosphere, before the shootout broke out, Lieutenant Niu Wen, who was guarding the front position, took the first action.

I saw Lieutenant Niu Wen suddenly jumped up, and then threw out a large handful of M67 in his hand, and when those grenades were bouncing and rolling towards the big iron door in the corridor, Lieutenant Niu Wen suddenly pulled the grenade ring that had been strung together with a thin rope in advance, and deftly ripped it off in one fell swoop.

"There is an explosion!" After finishing the throw, Lieutenant Niu Wen immediately yelled, and then he quickly turned around and squatted down, and at the same time pressed his helmet tightly with one hand, and at this time, the garrison soldiers who were closer to the corridor also followed Lieutenant Niu Wen's example one by one, desperately tightening their bodies into the bunker to avoid the shock wave of the explosion.

"......Boom! Under the loud sound of "Thorn Lala ......", it seemed that the entire corridor trembled, and the power of 6 M67 grenades superimposed together, it was not a simple one plus one greater than two, at least ten times stronger!

And under the crushing of such a fierce force, the iron rod used by the undead team to support the iron gate was bent hard, and then it was far away from the explosion point, and Captain Frank, who had been staring at the iron gate, saw that the solid iron gate was bent up by the shock wave instantly, and then slid out far away, leaving a friction spark on the concrete floor.

"Fire!" Captain Frank shouted excitedly when he saw that the big iron gate was finally gone, and then the guns in the hands of the garrison began to fire frantically, because everyone had similar thoughts and wanted to take advantage of the chaos to inflict a good wound on the enemy.

"Tutu...... However......, when the smoke and dust of the explosion cleared, the American GIs who fired were surprised to see that there were only two twisted iron rods in the corridor, and they could not even see a corpse or a wounded.

Could it be that the other party could have predicted the actions of his side and evacuated all the personnel to the room in the corridor before the grenade exploded, this is impossible!

As soon as Lieutenant Niu Wen, who was full of doubts, thought of this, a dangerous premonition suddenly flashed, and when Lieutenant Niu Wen shouted frantically: "Retreat, retreat, get out of the way immediately." At the time of these words, the fierce counterattack of the undead team had already come, and at the same time, 3-4 pearl grenades were thrown over.

In a hurry, Lieutenant Niu Wen only had time to pounce on the back, and when Captain Frank pulled a system operator and fell behind the console together, countless small steel balls in the pearl grenade began to wreak havoc on the side of the garrison.

"Bang bang, whoosh...... , flutter ...... and when ......"

In an instant, in a continuous crisp sound like a crumbling bean, the dense steel balls fell indiscriminately on the walls, debris, ceilings and the bodies of American soldiers.

Hands, feet, neck, in short, body armor, bulletproof steel helmets and parts that the bunker did not take into account, but the cruel little steel balls all found the door, and as a result, screams and cries immediately sounded at the scene.

When Lieutenant Niu Wen's subordinates suffered heavy casualties in the blink of an eye, the four people, led by the undead himself, took the opportunity to line up and rushed out of the room in the corridor quickly, and they began to fire quickly and accurately while approaching the combat center.

Although this is a group of grandfather soldiers who are more than 60 years old, their tactics are very advanced; the four people in the front row, they all put the AR15 on their shoulders steadily, and then take a single burst of fire, firing at a frequency of one shot per second, in order to effectively avoid the waste caused by overlapping firepower, these four guys simply divided the battlefield in front of them into four areas, each responsible for a small piece, so that they only need to adjust the muzzle slightly to block all the enemy.

In addition, while constantly pulling the trigger, the undead also moved forward with a uniform pace, adopting a similar method of pushing flat, and quickly forced to the end of the corridor, leaving no respite for the opponent.

After arriving at the door of the combat center, the four of them did not directly disperse and split up to face the enemy, but continued to gather together and ruthlessly and quickly suppressed any soldiers who dared to resist and open fire in any position in front of them!

Seeing the undead, they rushed up, whether it was the garrison soldiers in front or the civilian soldiers in the back, they had just experienced the baptism of small steel balls, and the cooperation and close formation between each other were all sent away, and everyone fell into the unfavorable situation of fighting on their own.

However, seeing the desperate critical moment, as long as the scene can still move, they naturally all shoot and resist, wanting to use the remaining numerical advantage to drown the enemy, but unfortunately the courage of the American soldiers, they are struggling to fight back, but under the continuous accurate shooting of the undead squad, it ironically becomes a roll call of active death!
