The first siege of the city, the Zerg adopted the strategy of encircling on all sides, this strategy was very useful in the past when the power of the human electromagnetic gun was insufficient, but now the power of the human electromagnetic gun has increased greatly, and the battle line on all sides is too long, which provides a full stage for the long-range firepower of the human race, and in a short period of time, it has caused terrible casualties to the Zerg.

The retreating Zerg quickly shrank, and their second attack adopted a strategy of focusing on breakthroughs, concentrating a large number of tank worms in an area twenty or thirty meters wide, and launching a wave of attacks on the steel walls of the Miners' City.

Because the battle line is too narrow, the human firepower cannot be spread, first of all, the high-speed electromagnetic machine guns distributed on the city wall, only a dozen or so can play a role, and the mecha warriors who can stand on the city wall are also very limited, and the formed firepower network cannot stop the death commando team composed of all tank worms.

When the Tank Worm Spearhead broke through to the bottom of the city wall, the sharp knife worm hidden behind the Tank Worm immediately surged out. At this time, the Zerg's all-terrain passing ability reflected its terrifying, and countless sharp knife insects rushed to the city wall at the speed of a flat charge like ants.

Once the sharp knife insect rushes up to the city wall, the defenders on the combat platform within the city wall will be cleared in a short time, and the Zerg who have lost their blocking will soon occupy this section of the city wall, once a large number of Zerg attack the city and start a street fight, human beings are definitely not the opponent of the Zerg.

At this moment of crisis, I don't know if it was the mecha warrior who took the lead, activated the flight function on the armor, flew into the air, and provided fire support to the defenders on the city wall from the air.

Alerted by this warrior, a large number of mecha warriors and even armored vehicles that came to the aid nearby rose into the air. A dense network of fire was formed over the city walls.

As more and more mecha warriors and armored vehicles took to the air, the sharp knife insects that climbed the city wall were quickly defeated. Next, the tank worms that were destroying the city walls under the city were also torn apart one by one. The Zerg's tidal attack was finally contained and repulsed.

The ensuing battle completely upended humanity's understanding of the Zerg.

Attacking the east and attacking the west, multi-way offensive key breakthroughs, digging tunnels...... Wait, a siege battle was played by the Zerg, and the wisdom embodied in it makes people shudder.

Fortunately, at the beginning of the construction of the Miners' City, in order to stabilize the foundation, the builders at that time carried out a lot of blasting and landfilling on the city foundation, eliminating the holes under the city foundation, otherwise with the Zerg's ability to dig holes. It has long been blooming all over the city.

Due to the blasting, the foundation structure under the city became loose, and the crypts dug by the Zerg were very easy to collapse.

The human beings who have been in peace for thousands of years have also grown up rapidly in the on-site teaching of the Zerg, and gradually adapted to the cruelty of war, not only were they not defeated by the dazzling tactics of the Zerg, but they became more and more impressive, and fought back the attacks of the Zerg again and again, and the most dangerous of them were even attacked by the Zerg into the city. But they still managed to fight back and drove them out.

Although the humans repelled the attacks of the Zerg again and again, they fought very fiercely and suffered very heavy casualties.

When Bai Qi led the team to the vicinity of the Miners' City. The Zerg were divided into eight routes, attacking from eight directions at the same time. Thousands of stealth mosquitoes in the sky are concentrated in one place, staring at the battlefield below. It's not hard to guess once humans in one direction of attack show inadequacy. These thousands of stealth mosquitoes will swoop down and launch a focused attack in this direction.

Bai Qi left the Federation mecha warriors behind, and led three armored vehicles and all the space soldiers under him into the detection range of the Zerg, but to his disappointment, the Zerg ignored his appearance at all, no matter how he teased him, not a single bug looked back at him.

For two days in a row, Bai Qi returned in vain, until he heard that the system had released a new mission, "Defending the Miner City".

The release of this new mission made Bai Qi overjoyed, these people under his command were alone in front of the Zerg army, and many ideas could not be implemented, if they could gather all the space warriors and the mecha warriors they recruited, it would be very useful.

After receiving a new mission, Bai Qi withdrew from the Red Plateau in one breath and returned to Fort 13.

The space soldiers who remained in the fortress had already mobilized their mecha warriors and armored vehicles for transporting troops according to their ranks, and were ready to go to battle.

After returning to the fortress, Bai Qi didn't care about these space soldiers resisting his orders before, and immediately accepted them.

He organized all the mecha warriors recruited by all the soldiers, and then determined the command sequence of these mecha warriors, so that each mecha warrior knew who he was commanding on the battlefield and who should obey his orders.

Due to the previous completion of the task of transforming the electromagnetic gun technology, each space soldier in Fort 13 has received fifty points of federal merit, so most of the soldiers have obtained the federal rank of sergeant, and they can mobilize a federal squadron, thirty mecha warriors, and a few space warriors with relatively high merit, such as Amos and Manstein, originally had the rank of sergeant, and after adding fifty federal merits, they obtained the rank of warrant officer, and they can mobilize a federal brigade and one hundred mecha warriors.

As a result, the total number of mecha warriors recruited by all the space soldiers of Fort 13 was more than 3,000 people.

Bai Qi divided the three thousand men into three divisions, one under the command of Amos, one under the command of Manstein, and one under the command of Barrian.

Bai Qi also used Brigadier General Huo Enze, the commander of the fortress, to transfer a group of officers from the fortress to serve as the grassroots commanders among the mecha warriors under him.

After the reorganization was completed, Bai Qi also gave a little training to these 3,000 soldiers.

The auxiliary skill of "command" is a skill that every space soldier with a slight status must learn, this skill is very complex, from the command of small-scale battles with cold weapons, to the combat command at the battalion and company level in the interstellar era, it is all-encompassing, and it is very helpful for space soldiers to command small teams to perform tasks, or integrate large temporary teams to perform tasks.

Amos and Manstein, as the leaders of the veteran team, both have a command skill level of up to LV20, and Barrian, as the commander of the backbone team, has also strengthened his command skills to LV20.

Therefore, after half a day of integration training, the three detachment leaders are basically familiar with the grassroots officers under their command, and also let the grassroots officers basically get familiar with their superiors, at least in terms of communication, there is no problem.

In fact, the more modern the army, the easier it is to command, although the development of the federal army is somewhat unbalanced due to the lack of war, but the communication and command system of the interstellar era is still countless times more advanced than the era in which Bai Qi lives, and the advanced communication and intelligent command system makes it very easy and meticulous for the superiors to grasp their subordinates.
