The bombardment lasted nearly an hour, and the dozens of Silicon Battleships flew away after dropping all the bombs.

I have to admit that this time it is the main army of the silicon charm army. Not to mention, in just one hour, the Silicon Charm Legion outside the barracks not only completed the deployment adjustment before the attack, but also built a simple defense line, and put the ironclad frenzy that is most suitable for defensive operations at the forefront. Behind this line of defense, the Silicon Legion set up a large number of defensive weapons, ready to deal with the shelling.

Apparently, the enemy has learned his lesson and knows that the human legions have a threatening heavy artillery.

However, the commander of the Silicon Charm army did not notice that after the Silicon Charm battleship was withdrawn, several small detectors flew out of the barracks. These small probes are the best of the Weaver family, and not only are they extremely small, but they also emit a weak signal that is difficult for enemies to detect.

In other words, every move of the Silicon Charm army is under Yang Yi's control.

After figuring out the situation of the Silicon Charm army, Yang Yi immediately adjusted the battle plan and did not let the heavy artillery fire. The enemy has already completed the deployment of defenses, and there are so many defensive weapons, even if a hundred heavy guns are fired at full speed, it is impossible to inflict heavy damage on the enemy with artillery strikes. In addition, heavy artillery is exposed after firing. Although the enemy's warships have been withdrawn, the enemy's legions must have heavy weapons in them.

As a result, after the withdrawal of the enemy's battleships, the battlefield was quiet.

It's just a moment of silence.

As the Silicon Legion began to advance towards the barracks, the battle began again, and the Silicon Legion army was the first to shell the Legion's advance.

Under enemy shelling, the human officers and soldiers on the positions could only continue to stay in the bunkers.

Of course, it's not just the Silicon Charm army that has heavy artillery.

The shelling lasted fifteen minutes. Twenty Silicon Legions also advanced outside the barracks at this time.

Rushing ahead were five legions of ironclad frenzy, which stopped at a distance of about a kilometer from the barracks. Almost in the blink of an eye, the 50,000 ironclad battles of the five legions formed a battle line outside the barracks by changing their forms.

Seeing this scene, Yang Yi was shocked.

Although Yang Yi had long known that the ironclad frenzy was the strongest protected class in the Silicon Charm Alliance. It not only has great value in defensive operations, but also plays an important role in offensive battles. To put it simply, Ironclad is the equivalent of a heavy tank, with few drawbacks except for being bulkier. But Yang Yi had never heard of the ironclad madness that could transform his body form, let alone the scene of 50,000 ironclad battles being connected in a line.

Not only has Yang Yi never seen it, but no one else has seen it either.

When the 50,000 ironclad frenzy stopped together and gained a foothold, it was a strong one. A front that is almost impossible to break through with conventional means.

To put it bluntly, it's a line of defense made of rocks.

Behind these five legions of ironclad frenzy are fifteen legions of humanoid rock demons, and in the Silicon Alliance, humanoid rock demons are the most common and most suitable class for attack. Although the body of the Humanoid Rock Demon is not as strong as that of the Iron Armor Furious Battle, and the attack power is not as strong as the Iron Armor Battle, the Humanoid Rock Demon is more flexible and numerous. In large-scale ground warfare. The hordes of humanoid rock demons are an absolute nightmare for human officers and soldiers.

Fifteen legions are 150,000 humanoid rock demons.

If you let 150,000 humanoid rock demons attack at the same time. Even if you don't break through the defense line of the human legion, as long as you fight with the human legion, it will be a disaster.

You must know that it was the twenty legions brought by Yang Yi who guarded the defensive line.

In previous wars, even the regular army of the Human Federation, or even the main army, had a hard time taking advantage of thousands of humanoid rock demons. To put it simply. Whenever possible, the Human Legion will try to avoid hand-to-hand combat with humanoid rock demons. The best way to deal with the Humanoid Rock Demon is to carry out a massive artillery bombardment, killing and injuring the Humanoid Rock Demon as much as possible before it reaches the engagement distance of the infantry, or at least destroying the Humanoid Rock Demon attack line. If you let the humanoid rock demon rush closer, engage in a face-to-face fight. Not only will it be difficult for human officers and soldiers to take advantage, but they will inevitably suffer heavy casualties. In fact, in the past Greenwich Wars, the Silicon Charm Alliance has always used humanoid rock demons as cannon fodder, and its main value is to impact the enemy's defense line and fight with the enemy.

The four human legions were definitely no match for the fifteen humanoid rock demon legions.

In addition, a distance of a thousand meters is definitely not far.

With the speed of the humanoid rock demon, it only takes a few minutes to rush out of a thousand meters, and the effective range of the light weapons used by human officers and soldiers is only about a thousand meters. In these few minutes, even if the 40,000 officers and men of the four legions were fully armed, they could only take out a few enemies.

It's just that the enemy has already been killed, and there is nothing to hesitate about.

Just as the ironclad battle of the five legions changed form and formed a defensive line, the human legions guarding the defensive line also began to act.

Four hundred heavy tanks of four corps drove out of bunkers almost simultaneously.

Without an order from the command, four hundred heavy tanks were thrown into battle.

The Silicon Alliance has Iron Armor, while the Human Legion has heavy tanks.

In fact, in the entire Galactic Alliance, only the human legion has heavy tanks, and other civilizations, especially top civilizations and advanced civilizations, have long eliminated this heavy weapon that can only fight on the ground and is extremely bulky, and there is no need to rely on heavy tanks to fight the enemy.

The reason is that the Human Federation is only a sixth-class civilization and does not have many soldiers.

These heavy tanks are all from the Jade family's arsenal. Although it is made by the technology of the Human Federation, its combat effectiveness should definitely not be underestimated.

Four hundred heavy tanks are four hundred moving heavy guns.

While the main cannon of a heavy tank is not as powerful as the heavy cannon from the Thunderling, it is just as powerful, especially when dealing with enemies at close range.

A distance of a thousand meters is not a distance at all for the main gun on a heavy tank.

In the blink of an eye, artillery fire covered the defensive line formed by the ironclad frenzy.

Because the object of the bombardment is the ironclad frenzy, which is known for its protection, it is not high-explosive shells, but armor-piercing shells, that is, shells specially designed to deal with the ironclad frenzy.

It must be admitted that after five baptisms of GMT, the Human Legion has the most extensive combat experience in the entire Galactic Alliance, knows the enemy on the other side of the Greenwich Meteorite Belt best, knows how to fight the enemy, and knows how to defeat the enemy.

It can be said that in the past Greenwich Wars, the heavy tanks of the Human Legion and the ironclad frenzy of the Silicon Alliance were mortal enemies. In almost all ground battles in which the Human Legion participates, heavy tanks are the nemesis of ironclad mania, and only heavy tanks have the strength to fight against ironclad maniacs. The point is, among the weapons and equipment possessed by the Human Legion, only the main gun of a heavy tank can penetrate the hard skin of ironclad frenzy when firing directly at it. Even the strongest ironclad frenzy can be hit by an armor-piercing bullet from a heavy tank. Even if you don't hit the vital point, you can still make the Iron Armor Fierce Fight seriously injured and unable to continue the fight.

In one-on-one combat, the superiority of heavy tanks is extremely obvious.

If there is any disadvantage of heavy tanks, it is that there are too few of them.

Under normal circumstances, a corps has only a hundred heavy tanks, and even the main corps, or the corps performing defensive tasks, will not exceed two hundred. It's not that the production of heavy tanks can't go up, it's not that the production cost is too high, it's that it's difficult to transport. A heavy tank weighs tens of tons, more than 100 tons including additional weapons and armor, which is equivalent to 1,000 heavily armed soldiers. In other words, it takes a 10,000-ton ship to deliver a hundred heavy tanks. In addition, several ships are needed to deliver the ammunition and maintenance equipment, and these ships can transport almost a legion of soldiers, or to arm all the light weapons needed by a legion, or to sustain a legion for three months. Relatively speaking, the combat effectiveness of a hundred heavy tanks is certainly not comparable to that of a hundred thousand soldiers of a legion. If you take into account the combat attrition, the combat efficiency of heavy tanks is even lower.

In fact, this is also the key to the elimination of heavy tanks by the legions of other civilizations.

If there were better weapons, the Human Legion would also obscure heavy tanks.

Of course, until there is no better option, heavy tanks are still the most powerful and irreplaceable heavy weapons in the human legion.

Within 10 minutes, 400 heavy tanks fired 40,000 armor-piercing shells at a rate of 10 rounds per minute.

Although it was not a hundred shots, and not every shot hit the key point of the ironclad battle, such a fierce artillery bombardment still had an immediate effect.

By the time the enemy launched a counterattack, that is, a fire strike, and the 400 heavy tanks retreated to their bunkers, the defensive line formed by the ironclad frenzy was already full of holes. In addition, the humanoid rock demons who had gathered behind the line of defense and were preparing for the attack also suffered heavy casualties.

The power of armor-piercing shells should obviously not be underestimated.

Although these tanks are all made by the technology of the Human Federation, the armor-piercing projectiles they are equipped with are from the Jade family, and their performance is far superior to the standard armor-piercing bullets of the Human Legion. In the case of a vertical hit, it can definitely penetrate the skin of the Iron Armor Battle, and even penetrate the body of the Iron Armor Battle, posing a threat to the enemy behind the Iron Armor Battle. The humanoid rock demon is not physically strong, far less than the Iron Armor Battle.

Of course, it is certainly unrealistic to rely on the ten-minute firepower of 400 heavy tanks to destroy 200,000 Silicon Charm soldiers.

The tactics of the Silicon Charm army were also very old-fashioned, and after being attacked, they immediately began to counterattack, and the fifteen humanoid rock demon legions did not give up the attack.

As soon as the shelling began, fifteen legions of humanoid rock demons rushed out from behind the ironclad defenses.

Suppressed by artillery fire, heavy tanks could not get out of cover for a counterattack. It's just that the Silicon Charm army is only targeting the heavy tanks on the defensive line.

Obviously, the human legion has more heavy firepower than just heavy tanks. (To be continued.) )
