Chapter 373: Accident

The operational background of the brood raid battle plan is modeled after the environment of the sub-brood where the brain worm is located, and there are several prerequisites for such a battle plan:

First, the mother nest is huge, has no atmosphere on the surface, and is composed of silicate rocks and mixed metals such as iron and nickel.

Second, the inside of the brood extends in all directions, and most of the Zerg combatants are all deployed in the underground passages that extend in all directions, and there are no or very few large numbers of Zerg combatants on the surface of the brood;

Thirdly, the guardian strength of the brood is not very strong, and the vast majority of the zerg are not very prepared, and when the assault fleet attacks, the pg on the periphery of the brood lack reaction time. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

However, the actual situation is very different from what was expected in the battle plan, first of all, the thick atmosphere that surrounds the outer layer of the brood. The presence of the atmosphere definitely caught the soldiers of the landing operation by surprise. Not to mention that the existence of the atmosphere greatly reduces the power of energy weapons, but the masking effect of the dense atmosphere alone greatly reduces the monitoring and fire support effect of the frigates used for ground support in high-altitude orbits.

In the battle plan formulated, the Vanguard Regiment did not need to worry about the Zerg's firepower from the surface and air of the planet. Because according to the original plan, all these tasks were completed by small porcupine-class frigates in orbit. Not only can they fend off the onslaught of the enemy's individual fighter groups on the fleet, but in terms of ground support, the 50mm electromagnetic cannon and the 30 caliber energy cannon under the belly of the ship can deliver devastating blows to the enemy's marines.

But the existence of the planet's atmosphere puts a big question mark on all this! The dense atmosphere makes it more difficult for frigates to monitor the planet's surface. This is relatively easy to solve, as long as there are a few points of contact between the ground and the fleet. But the dense clouds obscured the overwhelming flying Zerg, which was very bad.

The unmanned individual fighters equipped with the fleet are mainly adapted to combat in the space environment, and their aerodynamic layout is not suitable for operations in the atmosphere. Moreover, there are so many flying zergs that they can't cope with it with individual unmanned fighters alone.

Just the flying Zerg within the field of vision, roughly estimated, their number exceeds 20 million, and there are countless such Zerg combat soldiers in the distance. In this regard, how many unmanned fighters can the fleet send? Even if you use an octopus missile, you won't be able to distinguish so many people on the enemy mark.

In a word, the plan did not change quickly, and the command was a big miscalculation this time. However, now that the combat operation has already begun, it must still be carried out, even if the conditions are very different from the original plan. More than 150,000 soldiers were thrown to the planet like seeds, but they could not be gathered in a short time, and it was too late to retreat at this time, no matter what, they had to fight first.

The huge alloy soles of the "Dong ......" stomped heavily on the earthy yellow ground, splashing up bursts of dust, making the already dirty air even hazy. Cheng Aiguo hurriedly stood up, opened his identification code, and began to gallop towards the passage two kilometers away.

The identification code identifies the authority of the commander, and in the chaotic battlefield, the soldiers' semi-intelligent assistant programs will select the nearest commander with a higher authority when they cannot find a direct officer, and all the nearby soldiers are moving closer to the commander with senior authority, forming a combat team with combat effectiveness as quickly as possible.

As the supreme commander of the First Pioneer Regiment, Cheng Aiguo is the existence with the highest authority on the battlefield. As Cheng Aiguo began to rush towards the passage, on the battlefield, all the soldiers of the vanguard regiment approached the passage in unison. Near the entrance of the passage, Li Jiaxin, commander of the 2nd Combat Battalion of the 1st Pioneer Regiment, had already commanded the soldiers of the 2nd Battalion to establish a sniper defense line 500 meters away from the entrance of the passage.

Perpendicular to the 2nd Combat Battalion, the 6th Combat Battalion, under the command of its commander Shiro Ohno, held back the oncoming Zerg combatants. However, less than one-third of the Sixth Combat Battalion was built, and the defensive line was too open, and in many places the east wall was completely demolished to make up for the west wall, and there were loopholes everywhere. Fortunately, soldiers continued to join the sniper ranks, and by the time Cheng Aiguo arrived at the edge of the passage, the defense line around the entire passage had gradually stabilized.

"Number 2, number 6! Report back on the situation! "The 10 combat battalions of the Pioneer Regiment are distributed in the five directions of the brood, and the second and sixth combat battalions are responsible for this passage where Cheng Aiguo is located.

"It's not very good, when I landed, I was caught off guard by the Zerg flying class, many people were all trapped in it, and there are still a small number of people who haven't rushed out. Some people rushed in the wrong direction, and it was very likely that they ran away from the entrance of the passage, "The situation of the second combat battalion is better, more than three-quarters of the soldiers have completed the reconstruction, and the number of people gathered here has reached 12,000.

"We're pretty much the same, but the situation is even worse, not only are there flying zergs in the air where we landed, but there are also a large number of marines on the ground, and all the people who can reach here in the sixth combat battalion are killed from the sea of worms. Many people were separated during the impact and are now in emergency contact. Fifteen minutes later, three battle groups are expected to rush in from the direction of two o'clock, and we are preparing to respond," Shiro Ohno gave a brief account of the situation in the 6th Battle Battalion.

While the two were talking, the overwhelming Zerg army had arrived, and on the horizon in the distance, the black-pressed Zerg marines rushed over like a mountain of people. These marines are very peculiar, although their body composition is bioorganic, but the various organs on their bodies are completely close to the direction of the fighting machine. To use a technical word, it is "biological weapons".

At the forefront were six stout tiger-like Zerg marines. Unlike the Zerg marines they had encountered in the sub-brood before, these tiger-like marines were not very large, the largest was about three meters long, covered with metallic scale armor, with horns on their heads, and gray-brown fangs more than half a meter long on both sides of their mouths. There is no doubt that these sharp ramming angles and sharp teeth are absolutely capable of piercing general armor defenses.

On the back of the tiger, there is a biological turret that can rotate freely, and the barrels of the two energy slurry cannons emit green flashes, and from time to time from the inside of the barrels throw out spherical energy cannonballs with a diameter of more than ten centimeters, roaring and rushing towards the defense line of the second and sixth combat battalions, smashing on the charged armor of the defense of the Xingtian mecha and sending out violent explosions and dazzling flashes.

The hateful thing is that these tiger-like marines are very agile, and they are not large enough to dodge and dodge. The fifteen-meter-tall Xingtian Mecha was simply a behemoth compared to it. Many of the attacks were fired from a high altitude on the ground, and the shock wave from the violent explosion could only knock the marines over, and it was difficult to inflict substantial damage on them.

Another point is that the surface of the planet has a curve, and the attack of energy weapons is a straight line. Therefore, beyond the horizon in the distance, the Zerg marines were not attacked in the first place, and they were still pouring in.

In addition to the original tiger-like beast form, these new Zerg marines also appeared as a tentacle monster with spider legs and tentacles on their upper bodies. Each of these tentacles can fire energy cannons outward, and unless they hit their body, if one of the tentacles survives, their attacks will not stop.

What's worse is that the regeneration ability of these tentacle monsters is very terrifying. Cheng Aiguo had seen with his own eyes a shattered tentacle monster that had been bombarded get back up from the slurry everywhere in just two minutes and continue to attack the defensive line. This phenomenon is very common, and many soldiers have suffered a lot in this regard.

Before the threat of the Zerg marines on the ground was lifted, the attacks of the flying Zerg in the sky followed. The overwhelming dark clouds obscured the sky above the defense line into an airtight air, and although the mecha team in charge of air defense had been doing their best to destroy the enemy, the intensive bombardment still fell on everyone's heads, and the clouds were gloomy for a while, and morale plummeted.
