Maybe it is because the environment on the human-worm battlefield in Area C is too noisy, the sound of explosions and rifle strafing sounds interfered with, and the tank troops did not hear the call for support? Or maybe it is because they did not receive the order from the base commander? Or, it is more likely because the Marine Corps' first line of defense is only more than 100 meters away from the insect swarm, which is really too close?

Therefore, the tank troops that had been deployed in the base command center did not rashly respond to the request for artillery support from the Marine Captains Garen and Dryus.

Bastard! Where is the tank unit?

Da da da da da!!!

Garen was still shooting hard, and from the beginning of the battle to the present, the flames at the muzzle of his rifle have not stopped.

"ah!!"

Suddenly, in the first line of defense of the Marines, there was a scream of humanity tonight for the first time.

It turned out that a bug slipped into the defense line of several Marines not far from Garen's left. Then, it took the opportunity to suddenly rise up, pounced on the back of an unlucky guy, and began to wield its two huge sickle-like arthropods frantically. Every attack of it could actually penetrate deeply into the armored power combat uniform made of high-strength metal?

Da da da da da!!!

Then, when the other Marines heard the screams and turned their guns to help him break the hideous insect that broke into the front into pieces, the unlucky Marine was already lying on the ground and still moving.

There was only bright red human blood mixed with the corrosive liquid of the insects, flowing all over the ground...

Damn it!

"All columns on the second line of defense will continue to maintain firepower output, suppress the swarm, and others will retreat to the second line of defense immediately to defend, hurry up! Don't fight!"

After secretly cursing those unreliable tank troops, Galen immediately issued an order to retreat.

A continuous swarm of insects was continuously rushing out of the huge crypt, and the first line of defense was too close to the entrance of the hole. Without sufficient buffering distance, it was no longer necessary to defend against those insects with speed and quantity.

Now, the number of bugs is much larger than they expected. In addition, their first defense line is too close to the collapsed hole, so the bodies of the monster bugs that have accumulated more and more have seriously hindered their shooting sight.

Just now, he even saw two more bugs. After a few times under the cover of their companions' bodies, they flew into a shooting position on the Marines' defense line. Although they were quickly smashed into pieces by dense bullets on the spot, the two bugs also caused serious casualties to the Marines at that position in that short period of time.

In close combat, those recruits who do not have much practical experience and are prone to panic, have the panic shooting of rifles in their hands, or have only a bayonet less than 30 cm long on the muzzle, which obviously does not have much advantage for insects who are particularly good at melee combat.

"Sizi... Marines will answer when they hear it! This is the tank unit. We are ready for artillery. The first round of coverage shooting is about to be launched. Please be prepared to avoid it!"

Finally, when the Marines on the first line of defense were about to successfully retreat into the second line of siege, the tank troops' response rang out in the channel of two Marine Commanders Garen and Dryus.

"You damn it, no wonder you're talking nonsense, hurry up and fire!!"

The battle situation was so bad that the tank soldiers were still silly, and Dryus sweared on the spot.

"The shelling is coming! Everyone, hurry up! Retreat to the second line of defense at full speed!!"

"Hurry up! Everyone retreat!"

After finally hearing the response from the tank troops, the two Marine Commanders, Dryus and Garen, continued to rush to the swarm of stinging nail bullets, shouted loudly in the channel and slowly retreated.

It was not until they saw most of the Marines in the First Column began to obey orders and turned around and retreat at high speed that they both stopped shooting, each carrying the electromagnetic rifle that had been beaten with a red barrel, turned around and ran quickly towards the second line of defense.

Hiss...

At this time, the swarms that had lost the close firepower of the Marines were finally able to cross the high hills made up of the bodies of their companions, and chased the Marines who were retreating at full speed like a tide.

"Run quickly! Bastard! Don't shoot back! People on the second defense line should be careful and fire to cover us!"

When Dryus, who was retreating, saw a running Marine in the distance. He didn't know whether it was due to panic or courage, but he stopped while running, turned around and opened fire. Then, he was soon flooded by the swarm of sea-like insects, and his eyes were bursting and shouting loudly in the combat channel.

That bastard, he was deliberately trying to seek death just now, right? Then, he got his wish! There must be another place on the Marines' list of deaths!

Dada da... Dada da!!!

It was pitiful that after the Marines of the First Column had just run to the second encirclement line, the Marines of the Second Column, who had been waiting for the battle, finally opened fire one after another. The metal storm like rain shot towards the swarm of insects that were rushing towards the tide, and almost stopped their rushing towards the storm of 50 meters away.

After the Marines in the First Column adjusted their state, started changing magazines or simply changed weapons on the spot and joined the shooting, they once again pushed the swarm back to the open area a hundred meters away from the second encirclement line.

"All Marines, please note that after three seconds, a saturated cover shelling will be carried out, and the shelling will last for one minute. Please do not approach the shelling area at will!"

At this time, the slow voice of the tank troops commander came from the public channel of all Marines, and then the opponent's three-second countdown.

"Three, two, one, the shelling begins!!"

At this time, in the open space in front of the base command center far away from Area C, less than twenty Marines were holding rifles and guarding the command center, making the defense seem a little weak.

However, not far from their guard circle, there were nine huge heavy siege tanks with siege mode that had already been launched.

Long before the battle began, the tanks were ordered to convert from assault mode to siege mode early, set all the parameters, and waited for it.

The two huge track wheels on their side have been folded up and turned into two pairs of huge gun mounts and have been firmly rooted in the earth. The two pairs of track wheels in front and back are spread out into pairs of figure-eight shapes, and use the front end to ground to tightly fix the entire huge tank body of the tank. Even their 80mm-caliber double-barrel cannon has long been switched to a 120mm-caliber arc shock gun.

The cannon tracks with green light that were unique to electromagnetic cannons were aimed at Area C where the sound of fighting was heard. The collapsed area where the insects emerged and the first line of defense that the Marines were forced to give up were all included in the bombardment range by them.

"Please note of each unit: one minute of rapid fire, fire!!!"

Boom! Boom! Boom! Boom!

With the command of the tank commander, the muzzles of nine huge tanks that had been lined up suddenly burst out from the huge flames caused by the friction between cannon shells and air. Then, nine 120 mm-caliber electromagnetic shells roared at an extremely high speed and smashed straight towards the entrance of the collapsed area!

Boom! Boom! Boom! Boom!

Soon, in the distant collapse area, nine clouds of small mushrooms formed by huge explosions and thick smoke soon rose near the collapse area.

Then, among the thick smoke flames and the exploded metal projectiles and gravel barrage, countless alien monsters and insects gathered on the ground and near the entrance of the cave were instantly cleared by fierce artillery fire. Countless insects or insect remnants were overturned by the shock waves generated by the explosion and exploded into the sky.

Red, green, or the remains of insects, as well as various strange liquids, splashed and fell into the entire C area like raining, with the violent explosions...

Soon, when the first round of volley shelling ended, the Marines were surprised to find that the density of the insects on the ground was more than half less? And most of the remaining ones were temporarily trapped in a brief concealed state caused by the explosion and shock of the shells.

And this was just the first round of artillery bombardment. In the distance, the nine tanks lined up near the base command center. At this time, in less than three seconds, their gun barrels lit up again.

Boom! Boom! Boom! Boom!

Another nine 120 mm arc shock cannon shells hit the scattered insects in a row.

Nine loud explosions sounded again, and after destroying countless crowds of insects, they were awakened in time.

Then, they screamed and began to charge towards the second line of defense of the landing team members.

Of course, this shelling is not over yet!

If the bugs think that human terrifying shells have ended, they will be wrong!

Just three seconds later, the third round of artillery bombardment came again. When the insects were shooting at the landing team's rifle and trying to rush through the encirclement blockade line, nine shells in the third round roared and smashed down. The nine flame mushrooms that exploded again instantly shattered them in the running. Countless insects roared and fell into the flames of the shells and the exploded steel ball barrage...

Then, three seconds later, before the third round of artillery flames had enough time to completely dissipate, the fourth round of artillery bombardment appeared again.

Boom! Boom! Boom! Boom!

Then,

Another fifth round of artillery attacks...

Before the flames of the shells exploded in front had dissipated, the sixth round came again...

These small-scale artillery units of the Hope humans used their artillery to let the insects on this planet know for the first time that their flesh and blood were so fragile in front of human heavy technological weapons!

When the 20th round of shelling was over, the one-minute rapid shelling of shelling was finally over... On the battlefield in Area C, there was a mess, no matter how alive or dead, there were almost not many insects intact.

A mere nine heavy tanks lasted for one minute of saturated shells. They actually poured out a total of 180 shells of 120mm caliber electromagnetic arc shock guns near the small collapse area and the first line of defense!

The entire battlefield and near the tilted hole in the collapsed area were all shot by their tank troops, and they were terrible! In countless large and small artillery pits, there were various broken corpses of insects, as well as their disgusting liquids that were interspersed with red and green...

At this time, the tank troops who had completed the support mission stopped firing. Their gun barrels, after each tank fired twenty shells in one minute, now had to enter a short cooling period. The electromagnetic gun rails of their tanks were slightly red and bursts of white smoke were emitted.

Da da...

The Marines were still shooting sporadically, but now, on the battlefield where they could see, no insects dared to rush out of the sloping hole, only some scattered insects were still staying on a messy battlefield. They were wailing, struggling, and looking around in panic, trying to find their companions, or, trying to escape from this hellish place?

Da da da da da!

Then, their fate was only caused by the Marines' ruthless shooting, and they were killed by name and place one by one.

Killing enemies on the battlefield is nothing to do with right or wrong, and there is no kindness!

"My mother! Galen, no wonder the tank troops didn't dare to respond to our call for support just now. If they really called over here without hesitation just now, I'm afraid no one in our first line of defense would survive?"

Dryus looked at the battlefields in front of him in a daze, saying with lingering fear.

This is just a minute of rapid shooting of nine tanks, which caused a hellish doomsday scene? Looking at the hideous and broken corpses of insects, everyone couldn't help swallowing.

Only a little tank can have such power. If they were a large group of tank groups and hundreds of tanks? What kind of power would it be?

They all know that now, in the heavy factory in the base, the workers and smart devices are working overtime to produce heavy arc siege tanks!

After all, this kind of heavy equipment that is used for attacking and siege has always been one of the core ground forces of human colonial armed forces! If, in another month or two, their ground base will at least have an army of hundreds of tanks, right?

By then, just with this terrifying artillery fire, these insects can’t emerge?

Sure, right?

"Are we... victorious?"

"Maybe..."

“…”

Countless Marines began to whisper and started talking on the channel.

Some even walked out of their defense line and took a few steps forward, as if they wanted to clean the battlefield and finish the fight against those bugs who were not dead yet?

"Everyone returns to the defense line! Don't be careless, look! Everyone should be careful, it seems that there is movement under the ground again!"

Sure enough, as Garen's voice fell, the hoarse and harsh sounds of insects roaring from the huge sloping hole came from the mouth of the huge sloping hole.
To be continued...
