The chariots were too far apart for either side to take advantage of, so they both drove at full speed and rushed forward. The distance between the two tank units gradually approached, and the Grizzly 3 vehicle on the march fired first. During the march, the first Grizzly Bear 3 tank accurately hit its opponent, only to see that the mouse tank that was hit at a distance of 600 meters actually shook for a moment and then continued to move forward. The hard tungsten alloy armor-piercing bullet pierced the armor but failed to penetrate it.

"Damn, this old turtle's shell is really thick enough." In the Grizzly Bear 3 chariot, the commander Shangguan scolded a sentence.

"Commander, this tungsten alloy armor-piercing bullet can't penetrate the other party, what should we do?" Gunner Gao Shiping asked.

Shangguan Feng's eyes turned to his heart: "Take out the armor shattering bullet at the bottom of our box, I haven't used it anyway, let's give it a try." ”

"That's right." Gao Shiping said: "I'll get it immediately." "The door of the ammunition box was opened, the head of one shot was yellow, the entire warhead was packed into a cylinder, and the rather thick and long shell was carried out by Gao Shiping, which was equipped with a small number of armor fragmentation shells.

Pushing the armor fragmentation shell into the gun chamber, the gunner quickly operated the gun, aimed at the still moving mouse chariot, and with a bang, the armor fragmentation shell flew quickly towards the opponent.

Armor fragmentation shells are different from solid armor-piercing bullets, it is full of plastic explosives, as long as the projectile hits the tank, the thin shell will deform or shatter under the action of huge impact force, and the plastic explosives inside are tightly attached to the surface of the armor like plaster.

The explosives neither shattered nor flew apart. Under the action of the time-delay fuse, the explosives stuck to the outside of the armor quickly detonate, and the resulting shock wave acts on the armor with a pressure of tens of billions of pascals, and huge stresses are transmitted to the inside of the armor.

This attack effect is like hitting a wall with a hammer, although the wall is not penetrated, but the skin on the back of the wall is peeling off piece by piece, and the powerful shock wave will penetrate the armor, turning the surface of the inner steel armor into butterfly-shaped fragments weighing several kilograms, or dozens of small fragments. These fragments, under the action of huge kinetic energy, will fly around the tank, destroying the crew killing equipment, and the intact tank will be incapacitated.

The cannonball fired by Gao Shiping was firmly stuck to one of the opponent's rat chariots, but with a deafening explosion, the rat chariot was unscathed. Startled by the explosion, the Boston charioteers burst out laughing when they saw that their tank was unscathed, and they laughed at the uselessness of the Chinese tank's cannon, but no one noticed that the chariot never moved again after being shot.

"It worked, it didn't move." Shangguan Feng shouted excitedly.

Gao Shiping nodded excitedly: "The effect is really good, let's go ahead and beat these old turtles of the Bostonians hard." ”

Armor Fragments are particularly effective against the Boston Vehicle's homogeneous armor composed entirely of steel, but the individual vehicles are not equipped with many Armor Fragmentation Shells, and they are quickly depleted. The approaching Rat tank fired continuously with the 128 mm caliber tank gun, and finally the Grizzly 3 tank was pierced through the armor.

Several Chinese tanks that had once been considered indestructible were destroyed, which shocked the Boston crowd, and they rushed over and engaged the Chinese army in a scuffle. Although the gun of the Grizzly 3 tank can also penetrate the opponent's armor, the caliber of the gun is more than 20 millimeters worse, and the opponent is a model that completely abandons mobility to improve armor protection, so except for the good effect of the armor fragmentation shell, the effect of other bullets is not good.

Looking at the casualties on the front line, Su Zhizhen frowned. At present, the weapons of the Chinese army need to be transported from the country thousands of miles away, and they cannot be compared with the Bostonians who are fighting on the inside line in terms of supply, so with the same number of losses, the Chinese army is not cost-effective.

By this time, the Vulture 1 attack aircraft had arrived, but the vehicles of both sides were scuffled, and they had no chance to bomb at all. "Order the tank units to withdraw from the battle." Su Zhizhen quickly gave the order that he wanted to leave room for the air force to attack.

Even when the Grizzly Bear 3 tank was reversing, it had a speed of nearly 40 kilometers per hour, so after the Chinese army received the order to retreat, they did not turn around and drove directly to the rear. This avoided facing the enemy with weak rear armor, and the Rat tank, which had a top speed of only twenty-seven kilometers per hour, could not catch up with them even if it moved forward.

While retreating under the cover of artillery fire, the Chinese army quickly disengaged from the other side. The distance between the two sides quickly widened, and the attack planes that had been hovering in the air saw the opportunity coming, and immediately pressed the nose of the opposing tank force into a dive.

The first attack aircraft flew low over the Mouse and dropped a 50-kilogram bomb on top of the vehicle. The Rat tank, although well armoured, was limited to frontal armor. The armor of the combat vehicle was divided into frontal, side, rear, bottom, and top armor, and its thickness was weakened sequentially. As the thinnest top armor of a combat vehicle, how can it withstand the explosion of a 50-kilogram aerial bomb.

After being hit by a bomb, the top of the turret was broken by the power of the explosives, and the huge force directly killed all the crew inside, and the tank emitted a puff of smoke and soon stopped moving.

Seeing the achievements of their companions, the other attack planes also lowered their noses and rushed towards those huge rat chariots. Seeing the opposing attack aircraft rushing towards them, the commanders who had just been hiding in the turret because of the chariot battle lifted the lid of the chariot one after another, leaned out and operated the anti-aircraft machine gun on the top of the chariot, and fired desperately at the attack plane.

Seeing that the opposing side was using anti-aircraft machine guns to resist, those attack planes strafed with large-caliber aviation machine guns. Attack aircraft were protected by armor, and the fire of anti-aircraft machine guns from combat vehicles did little damage to them, while large-caliber aviation machine guns were able to easily shred apart unprotected commanders.

In this battle between ground and air, the Vulture 1 attack aircraft won a complete victory, destroying more than 300 combat vehicles, most of them rats, while losing only a dozen aircraft of their own before the opposing anti-aircraft artillery units rushed up to cover them.

Seeing that something was wrong, Marshal Pershing quickly recalled his troops, but another group of albatross dive bombers flew over the battlefield and bombarded the retreating Boston army indiscriminately. The bombers, all infantry, and more than 20 of them loaded with special ammunition, dropped ceramic bombs on the crowds, while the other bombers deliberately avoided the dropping area of the biological bombs to prevent the bombs from destroying the small insects that carried the virus.

The retreating Boston soldiers had fled from the continuous bombardment, and all they wanted was to flee back to their own city as quickly as possible, and how to pay attention to the shattered aerial bombs that did not explode. The Bostonian people didn't pay attention, but it didn't mean that Su Zhizhen didn't pay attention, he quickly discovered these anomalies with a telescope: "Old Xiao, you are crazy, what should we do if you throw biological bombs on the battlefield and our people are infected?" ”

Xiao Jun said disapprerovingly: "It's not a big deal, as long as we don't pursue, and our fighters have already been vaccinated, so nothing will happen." Now the enemy has begun to suspect that the plague in those dozen cities has something to do with us, and if I drop these bombs on other cities, it will certainly arouse suspicion. If I rely on the other side to send the virus into the city like this, no one will suspect us, and you just wait to receive the city. ”

Su Zhizhen said: "What virus did you use this time?" ”

Xiao Jun smiled slightly and said, "It's nothing too good, it's just the plague that spreads the fastest, which is often referred to as the Black Death." ”

"What? This thing can easily cause a large-scale epidemic, and may even break out across the country. Su Zhizhen was startled when he heard it, and he heard the name of the Black Death.

It is said that hundreds of years ago, there was an epidemic of the Black Death in the Western Continent for a period of time, and the plague broke out intermittently for hundreds of years, resulting in the death of one-third of the population of the Western Continent and the almost extinction of the entire white world. Until now, people in the Western Continent still talk about the Black Death and call it the Grim Reaper, and in the film industry that has emerged in the past ten years, most of the thriller or tragedy movies shot by those countries in the Western Continent have the figure of the Black Death, which shows the depth of its harm to the people of the Western Continent.

Seeing Su Zhizhen's nervous appearance, Xiao Jun smiled and said: "It doesn't matter, we have countermeasures, and each virus has a corresponding vaccine, otherwise scientists will not let these viruses flow out of the laboratory." Su Zhizhen nodded: "I hope so, but you must do a good job of protection, and all the people in the public court and the troops in the south must also take precautions, and they can't be allowed to die because of this." Although Su Zhizhen said so, in fact, he was still very uneasy.

Instead of pursuing the Boston army, the Chinese army retreated to the city and continued to hold on to the dozen or so cities it had occupied, while reporting to the country and requesting the dispatch of some workers and engineers to restore production in the cities as soon as possible and replenish the army with weapons and ammunition.

Field Marshal Pershing fled back to Davenport with his troops, who had lost a large number of rat chariots, and although the loss of troops was not large, the chariots had lost most of them, and this was due to the fact that his own chariots had a certain advantage. Marshal Pershing lamented that the war could not be fought without air supremacy, and he had no idea what a terrible demon he had brought back, and without the knowledge of the Bostonians, a plague that had almost wiped out the Bostonians was quietly spreading, and it would soon be able to demonstrate its powerful destructive power as a god of death.
