One Thousand Five Hundred and Twelve No Matter the Cost (3)

Knowing where the insect swarm is, the artilleryman can hit the insect swarm with his eyes closed. The cannon fires one after another, and each shell falls on the road accurately.

When Beidu decided to place the orbital elevator here, the entire Kalidan was already deserted. Everything in the Equator Base was built bit by bit by the engineering troops, and this road was no exception.

Although it is the only connecting channel between the port and the base, the underground engineering is the top priority of the entire base. This road is just repaired casually. The roadbed is just rammed soil, and the road surface is just a layer of rammed soil. Not as good as domestic rural roads.

The strength of such a road surface can be imagined. Every time a shell falls, there is a large crater. After a while, this road is as bumpy as the moon, with craters of varying depths everywhere.

Everyone knows that this road is completely abandoned, but no one is worried about this, because there are still engineers in the base, and it is just a broken road that can be repaired and used.

Moreover, it is not certain whether it will be repaired or not in the end.

The shelling was very effective. The shells blocked the insect swarm three kilometers away, preventing them from advancing even an inch.

But the swarm of insects had no intention of retreating, and kept rushing forward with their necks bent.

Liu Huaidong felt that continuing the fight like this was not an option. He hesitated for a while and said: "Let the artillery stop first and try the laser cannon.

That's right, it's a laser cannon. There are only six sets in the entire base, placed in six directions on average. Only two can shoot at roads.

Zhang Chen wanted to say that he should have replaced the laser cannon a long time ago, but the words rolled around his mouth and swallowed back in his stomach.

Liu Huaidong is a relatively traditional soldier. Although his ability to accept new equipment is not weak at all, his tactical thinking is a bit behind the times. No matter what situation he encounters, the first thing that comes to mind is always those Traditional machine gun cannon.

Not only weapons and equipment, but also tactical ideas. If it were Zhang Chen's command, he would have ordered the artillery to stop shooting and move the insect swarm closer before attacking - the new equipment in the base is not only the laser cannon, but also two A set of infrasonic cannons and two sets of directional microwave cannons are powerful weapons for dealing with insects, but the range is relatively short, and the insect swarm must be brought close to be effective.

It is precisely because of this that these new weapons have not received much attention from Liu Huaidong, and have not been able to play their due role... Well, it cannot be said that, because since the base was built, there has been no precedent for large groups of giant insects to attack, sporadic The giant insect can't even get through the minefield, let alone get close to the base.

Liu Huaidong's order has been conveyed,

The sound of cannons that had been ringing suddenly stopped. Many uninformed soldiers thought that the battle was over, but they did not expect that the insect swarm was quickly approaching the base.

Liu Huaidong always believed that it was not a good thing for the insect swarm to approach the base, so he did not give the insect swarm a chance to continue approaching, but ordered the laser cannon to fire immediately.

At this time, the distance between the insect swarm and the base was still two kilometers, and two lasers as thick as a finger and invisible to the naked eye swept past the ground close to the left and right.

The running insect swarm seemed to have pressed a stop button. The giant insects rushing at the front were cut open from the front by the laser and fell to the ground one after another.

The giant bugs behind continued to move forward, and the cross lasers swept back again, and another batch of giant bugs fell to the ground.

After scanning several times in succession, the alien finally realized that something was wrong and ordered the insect swarm to stop advancing.

Liu Huaidong couldn't help but sneer, is this a place where you can come and leave whenever you want?

The laser continued to sweep across, and not a single giant insect that rushed into the range of the laser cannon survived.

This is not because the laser cannon is so powerful, but because the giant insects have no concept of escaping from orders. The aliens ordered the insect swarm to stop, but did not order the insect swarm to evacuate. So the insects suffered a tragedy. Rather than saying that the insect swarm was being defended, Annihilation by the military might as well be said to be trapping them to death by aliens.

At this time, the aliens had realized that it was impossible for the insect swarms to attack the base from the front, but they still had no intention of stopping the attack and continued to send insect swarms to attack.

This time it is no longer a frontal single-point breakthrough, but a comprehensive assault in all directions.

It wasn't until the aliens launched a full-scale attack that Liu Huaidong realized that the base was not as strong as he imagined, because the attack came not only from the ground, but also from the underground and the sky, a true all-round three-dimensional attack.

It's very busy now. There are swarms of insects on the ground, servants in the air, and various weapons in the base are firing wildly. The ammunition consumed every minute is calculated in tons.

As for the underground, haha, Liu Huaidong didn't care at all, and only arranged for a part of the troops to be on guard.

The aliens' tactics are indeed very three-dimensional, but they are also a bit too taken for granted. Their idea should be to use ground and sky attacks to attract the attention of the defenders, then open a gap underground, and finally attack the base.

But the aliens did not expect that when Beidu built the equatorial base, they thought of this. Not only did they build a reinforced concrete protective layer more than ten meters thick underground, but they also set up a buffer zone in the protected area. Even if the giant After the insects burrowed through the concrete and rushed into the base, they had to face layers of iron railings and a thirty-meter buffer zone.

You know, the Equator Base was not built casually. The first batch of underground cities were simply hollowed out underground, as long as people could be accommodated in them, and nothing else was considered at all.

However, as humans have gradually deepened their understanding of giant insects, the structure of underground cities has also been improved. The military has used all its more than ten years of experience in building underground cities on the equatorial base. It has various anti-insect measures. Want to break through the base? How can it be that easy?

However, the aliens are very determined. The insect swarm participating in the attack does not care about life and death, and it is clear that they want to accumulate victory with insect lives.

After this battle, all the officers and soldiers in the base had a new understanding of the madness of aliens.

Liu Huaidong later learned that it was not that the aliens were too crazy, but that all human bases in the tropical areas had been captured by aliens. Only the Equator base was still standing amid the onslaught of the insect swarms, almost becoming an alien Starman has a thorn in his side.

After so many human bases were taken down, the aliens couldn't believe it. In the end, this place couldn't be captured, so the aliens mobilized an army and launched one round after another of crazy attacks on the equatorial base.

The minefield was flattened, but the insect swarm did not stop; the laser cannon overheated, but the insect swarm did not stop; infrasonic cannons and directional microwave cannons crisscrossed the battlefield, killing and roasting all the giant insects close to the base, but the insect swarm still fought to the death Don’t retreat.

Liu Huaidong was well aware of the solidity of the base. He never believed that aliens could break through the base, but the attack of the insect swarms never stopped, and the sound of gunfire in the base never stopped. The mountains of ammunition were visible to the naked eye. Speed ​​of consumption, according to the current consumption rate, the base can only last for three days at most!
