The fortress group of Kunshan Mountain, showing a diagonal rectangle, is a valley area sandwiched by two mountain ranges, with only two exits from east and west.

The east and west exits were covered by fourteen-meter-high metal walls, while above the valleys on either side were fortified artillery fire. This defense system was laid out by the chief of the Ordnance Alliance a thousand years ago.

Six hundred years ago, when the automatic defense turret was not as powerful as it is today, it was controlled by multiple cities in turn, and the cities of Taiyun took advantage of this terrain to command the fire on the mountain and guard the danger.

Historically, attempts to storm this fortress failed to storm the Great Wall and died, for eleven. The largest of these was forty years before the Battle of Weishui.

Sisi organized six Great Wall and their team to attack from four directions, three Great Wall were killed, two Great Wall were seriously injured, and one Great Wall did not know what happened. This defeat indirectly led to the decline of Sisi's national strength, and in the subsequent Battle of Weishui, he was consumed alive by the Taiyun Empire.

In the last years of the Warring States period, the Kushan Pass was known as the unbreakable wall.

And now, with the enhancement of automated weapons, close defense guns are stronger than they were back then. With the establishment of the intelligent domain tower, the coverage, duration, and intensity of the domain system are much stronger than those of the city professionals stationed in the past.

At the time of the arrival of the Apocalypse Calendar.

The Mt. Fortress has been called an uncollapsible zone, and the Mt. Mt. Fortress has been quickly copied to other passes, and has been used by the military as a brood station for mobile bases.

Within this impregnable defensive circle, a dense network of railways is derived from outside. Rows of railways divide the fortress into multiple areas, each of which is like a parking lot with tens of thousands of tons of mobile bases and supporting facilities.

……

Today's Qianchuan's strategic thinking is very simple, that is, relying on the shells of these first-class large fortresses, holding the strategic points, and then sending the little Wangba (mobile base) out of the hole to hold the secondary strategic points.

Qianchuan Tower Defense Party: As long as all the mines are divided, no, as long as all the levels are preempted, then it will be like a rope to hang any opponents that may appear in Qianchuan.

This is the military theory of "static braking" that was developed 500 years ago when mobile bases were emerging.

Criticize in blazing words: When Wang Ba is used to it, he is addicted, and he likes to carry a turtle shell, so he never wants to put it down. In order to make it reasonable for him to be a turtle, he specially self-hypnotized a set of correct theories.

……

6 p.m. on the 8th.

A large-scale mecha corps had been spotted approaching in the fortress, and the supreme commanders in the fortress received the news and immediately paid close attention.

And inside the fortress, all areas began to move, and all the radars on the mountain were very stupidly turned on, not knowing at all that these radars would become targets for anti-radiation missiles.

There has been no large-scale war for 400 years, and the Qianchuan military system has not even played to the highest level of the old era, but it seems to be busy.

Scene 1: A shallow passage in the mountain defense circle, in which red lights warn each personnel to enter combat positions, and soldiers wearing dynamic bones line up on each runway to enter the defense circle and stand by in various combat positions.

Scene 2: In the central area of the Kunshan Fortress, a large center has been dug underground in the center of the tunnel, which is the intermediate command hub, and the commanders at the rank of colonel sit in the sub-control center. The intelligent system is aggregating the stereoscopic projection of the entire fortress, and the artificial intelligence is judging the situation of the assault group of the Order Army in the distance based on the reconnaissance drone.

Scene 3: In the deepest underground of the fortress, in the highest-level center, in the operation of a group of medical staff, the hibernation chamber like a cabinet is flashing blue light and is ready to be activated.

The head of the medical priest is Aakiko Lu (female, 64, looks like twenty-eight, long hair, but now it is blocked by a full-coverage helmet and cannot be seen).

She looked at the electronic clock, walked down the hall with the etiquette in place, and used the electronic helmet to report to the top elders in the hibernation chamber.

In the hibernation chamber of the hall, those who had been alive since the electric calendar opened their eyes without the slightest human emotion, and silently watched the soldiers on the screen descend from the city.

Ten years ago, someone said that there was an armored unit roaming outside the Kushan Pass and that it was a soldier coming to the city, which was a very funny word.

But now, the big movement of the Seventh Army in Junyu City has made the command in the fortress very cautious.

……

Right now.

The blazing white troops did not launch a general attack immediately, but sent small groups of troops to repeatedly cut into the fortress to attack, and used the form of harassment to engage in low-intensity confrontation with the fortress.

From time to time, dozens of rockets were smashed, and these rockets triggered the close defense artillery system on the fortress.

The close defense cannon was fired from the cave fortifications of the fortress by the rail system, the turning of the fort was very fast, and the bullet density was connected in a line, and on the whole, it was like a sword thousands of meters long, standing on the mountain and waving at the sky.

With this wave of the blow, all the flying objects were blown up in the air. Tungsten core armor-piercing warhead, the destruction of missile shells is devastating. Now there are hundreds of such close-in defense artillery systems, forming a penetrating firepower network.

……

The first thirty minutes of the total offensive.

Six large transport planes flew to a low altitude of 10 meters and dropped the airdrop containers, which were tightly packed and slammed into the ground under the cushion of air cushions, setting off a ring of impact smoke waves.

A mechanic temporarily recruited from the Northern United Industry Alliance, wearing a tentacle suit with a fool's operating system, began to perform the final maintenance of the assault mecha system.

It's right on the simple repair shop.

Blazing White is also personally on the field to repair his own mech.

This mecha has evolved to the extreme for assault, the wings are already very narrow, and the cockpit in the rear is large, allowing the operator to operate internally in a top-of-the-line individual mechanical combat suit.

And the top individual combat uniform is also made by Blazing White.

The height of 1.8 meters at this time, with this set of individual combat uniforms with clear mechanical structure and full of precision, has a sonorous metal.

Blazing patted the head of the assault mech's cone, which was now covered with brick-like reactive armor.

At this time, there was the sound of metal footsteps behind Blazing White, and Blazing White couldn't help but look back.

The person who came was a female officer of Imperial Spirit, Nan Yuelong (the captain of the reserve regiment chosen by Blazing White), but now it is the queen's style, and she can't show it in front of Blazing White.

She stepped forward and saluted decently and said, "Commander, the rear has already sent special electromagnetic bombs over." The captain looked blazing white. - She didn't say the word tactical nuclear bomb directly.

Blazing nodded.

Nan Yuelong hesitated for a few seconds and asked again: "Sir, now that you are fighting, when will this nuclear weapon be?" ”

Blazing White waved his hand: "No, no, what are you doing with this?" The defense system on the other side is not suitable for nuclear weapons, and this thing is scary after winning the war. ”

Nan Yuelong barely squeezed out a smile and persuaded him: "Commander, this Xiongguan is worth using this weapon." ”

Blazing White sneered: "No, this Xiongguan is worth my rush!" ”

……

At 7 o'clock in the afternoon of March 8, 547 year of the Apocalypse calendar, as the sun set on the western mountain, the red glow disappeared on the horizon, and a large number of flares were projected over the fortress of Kunshan.

The offensive began. The Dragon Guards attacked in three parts. In the north and south directions, a large number of troops were concentrated, and the defense system of the Kunshan Fortress immediately discovered that the orderly army in the flat theater in front had entered the range of long-range fire strikes by the fortress group.

On the mountain, one by one, the large fortress guns were opened and the barrels were raised, but in the face of the wave charge on the frontal battlefield of dozens of kilometers, the counterattack of the fortress guns was slightly loose.

The queue interval of the shock cluster is quite large, and there is a radar system in the sky that detects the trajectory of the shells, and this data link is transmitted to the ground dragon guards, so most of the dragon guards even if they happen to encounter artillery hits, the wings are slightly raised, and they avoid the fortress artillery strikes.

However, when the wave of massive attacks approached ten kilometers from the fortress.

Just like the ancient knights charged and threw javelins, of course, the scale of throwing is now ten kilometers, and the "javelins" thrown are heavy rocket artillery.

In the cluster of assault mecha speeding on the ground, rockets dragged white smoke clouds, cutting through the sky, like thousands of white hairs, gently blowing Xiguan with the east wind.

As the rain of rockets suppressed, the roar of the long-range fortress cannon on the mountain was like a tiger that broke its spine.

Exploding sparks swayed the trees on the mountain.

Although the outermost defense of the Mt. Kuoshan Fortress has not been completely abolished, it is now unable to provide fire cover.

After the defense of the fortress cannon as the "coat" of the fortress failed, it could only let the "underwear" withstand the storm.

In the dark bunker on the mountain, small laser defense towers popped out from the ground.

If there is no "accident" and such a hard impact, the dragon guards will be severely damaged under this layer of counterattack firepower.

However, the stars in the sky are exceptionally bright at this time.

……

Get into the perspective of the defending side.

On the fortress group, in the control center connected by the tunnels, the artificial intelligence that leads the defense and counterattack is busy, and the numbers are jumping quickly on the screen.

On the model of the mountain projected in the base hall, a number of laser and close defense systems are operating from the track to a suitable position, poking their heads out to prepare for a fatal blow to the incoming charging group.

But there was no joy on the faces of the commanders sitting in the control compartment of the fortress, because in the radar alarm, the dense batch of ballistic missiles in the sky was falling, and at this time, the field tower was locking on to the ballistic missiles with all its might. There were a lot of ballistic missiles, sixty-three rounds in all, and they seemed to be ready to come down at the same time.

And when it fell, it was just when the army of order arrived at the mountain front.

Just as these commanders, sitting in the control compartment, adjusted the ratio of firepower, a new alarm arrived. A large number of cruise missiles, thousands of rounds, appear in the radar's view.

These cruise missiles are closer than ballistic missiles at this time because they fly close to the ground. It has approached thirty kilometers and has caught up with the assault corps at an alarming speed, and is about to sweep over the heads of the assault corps!

It is expected to arrive at the same time as the ballistic missile!

……

If the firepower of automation gives the defenders the upper hand.

Then timing technology and information and communication technology will give the attacker an unprecedented advantage.

No matter how strong the defense is, as long as enough firepower is mobilized in a very short time, it can be smashed through, and then it is rushed down by the legion that follows closely.

And in a few seconds, the trajectory of these thousands of cruise missiles began to divide into two teams and multiple groups, which were about to attack the mountain fortress area from all directions.

In other words, the amount of fire that the fortress had to withstand immediately and instantly was unprecedented!

Times have changed!
