Intensive artillery fire re-covered the Japanese Imperial Palace, which had been reduced to ruins, and many Japanese who were in the process of relieving the disaster fell under the fire.

The soldiers of the Japanese Guards Division, who had stopped the defense around the palace, were also subjected to intensive artillery fire, and the artillery fire and fire continued to destroy the already crippled palace, and several sections of the palace wall that were still intact finally collapsed completely.

The dense artillery fire engulfed the defensive line established by the Japanese, and Xu Xinyu immediately ordered the troops to advance.

Under the cover of artillery fire, the sharp knife platoon did not encounter any resistance, and advanced directly to a place less than a hundred meters from the palace, and only eighty meters from the place covered by artillery fire.

The distance here is already quite dangerous, even if it is a coordinated infantry artillery, once it is about two hundred meters away from the edge of the artillery fire.

But after all, it is not the artillery fire of large-caliber heavy artillery, and Xu Xinyu is not worried about being affected by artillery fire.

Directing artillery to hit targets is originally the task of the knife platoon, and in the absence of a commanding height, let alone a hundred meters from the edge of the artillery coverage, even if it is fifty meters, it is not strange at all.

In the era when there were no tanks and tanks, infantry and artillery coordination sometimes fought for courage.

Especially in positional warfare, the coordination of infantry and artillery at a distance of 200 meters is often not obvious, and when the artillery fire is extended, when the infantry wants to get close to the enemy, the enemy has already reacted.

Therefore, based on the accuracy of artillery strikes, the distance of infantry and artillery coordination is within 100 meters, and if it is a flat charge, the distance of 100 meters is covered by machine guns and accurate marksmen, and the soldiers who attack can rush to the enemy within 12 seconds.

If necessary, it will be even more frenzied, and the infantry will move to eighty meters, or even fifty meters, from the edge of the artillery fire.

A heavy machine gun carried by the Knife Platoon was placed on a piece of wreckage eighty meters from the palace, and two men from the machine gun team were reinforcing the machine gun position, and the three precision shooters were also in the best firing position.

After five minutes of continuous shelling, the artillery fire began to extend, which was a signal to the infantry on the front line that the shelling was about to stop and that they should attack immediately.

As soon as the artillery fire was extended, Xu Xinyu immediately took all the infantry, braving the waves of cannonballs, and approached the palace.

After they had advanced for fifty meters, the remaining Japanese soldiers on the periphery of the palace without artillery fire also raised their heads, but in front of them, three accurate marksmen, and the infantry who alternately covered the advance.

A few surviving soldiers of the Japanese Guards Division had just poked their heads out of the rubble, and a few bullets immediately flew over, and their heads exploded like watermelons.

Other Japanese soldiers hiding in the rubble also immediately counterattacked, two heavy machine guns, one of which had been destroyed under artillery fire, and one heavy machine gun was lucky to avoid artillery fire.

However, when the two Japanese machine gunners were about to operate the heavy machine gun, the heavy machine guns of the Sharp Knife Platoon had already issued the fire button.

The dull sound of machine guns, dense bullets dismembered the two Japanese machine gunners in an instant, blood and body stumps, splashed on the heavy machine gun, and the ammunition box opened on the side, to the point of falling a bloody palm.

The 12.7 mm heavy machine gun was a brutal slaughter for the infantry, and even the Japanese soldiers hiding behind the wall could not avoid the heavy machine gun bullets that could easily penetrate the wall.

In modern warfare, whether it is a large-caliber machine gun or a large-caliber sniper rifle, in urban combat, there is no doubt about slaughter.

Because neither the walls of buildings nor the walls of buildings can stop such powerful large-caliber bullets.

The bullets that easily pierced the wall tore apart the Japanese soldiers who were hiding behind them, along with the wall, and even compared to the effect of being directly hit by a heavy machine gun, the soldiers who were hiding behind the wall died even more tragically.

Ordinary heavy machine gun bullets, due to the limited structural strength of the bullet body, when penetrating the wall, the movement trajectory becomes irregular, in a state of rolling and fragmentation, after penetrating the wall and then entering the human body, most of the huge bullets will explode in the human body, often a bullet hole, but after penetrating the body, it brings out a large piece of flesh and blood.

There was a Japanese soldier, a bullet pierced his stomach through the wall, and as a result, the bullet that penetrated from behind him brought out a large section of his spine and a blur of flesh and blood.

At high speed, the bullet has a limited ability to withstand after penetrating the wall, and the resistance of the human body to nature is like the last straw that breaks the camel's back, and the result will naturally be very tragic.

As a result, under the blow of heavy machine guns, behind the walls of the palace, patches of blood mist were filled, and the charred ground was stained red by patches of sprayed blood mist.

The soldiers of the Japanese Guards Division, who had never seen such a terrible weapon, were in a state of collapse at this moment.

Although the heavy machine guns of this era were not small in power and could smash walls at close range, each bullet like this directly penetrated the wall and killed those hiding behind, which was completely beyond their knowledge.

For this reason, these Japanese soldiers who did not die under the fire of the artillery fell under the terrible fire of the heavy machine guns, and when Xu Xinyu led the soldiers to rush in front of them, these Japanese soldiers who were dominated by the heavy machine guns did not even have time to react in time and were easily killed.

Breaking through the outer line of the palace, many Japanese soldiers still survived the artillery.

After entering the palace, Xu Xinyu directly killed several Japanese who were wailing on the edge of the crater.

The artillery fire just now killed many people in the palace, and many people were injured in the shelling, and it is very common to break hands and feet.

And in this era, there are very few people who can survive such wounded, after all, there is no anti-inflammatory medicine, once it is inflamed and ulcerated, it is a death, and the survival rate of amputation is not much better.

And the Red Guard Corps did not lack all kinds of medicines, but even if they were thrown into the sea, there was no need to save these Japanese.

In the face of wounded soldiers, the most simple way is to understand with one shot, so as not to have dry tongues in the ears.

In fact, during this period of warfare, the best way to deal with seriously injured soldiers was to completely relieve the pain.

Therefore, in the data of war casualties in this era, there are often two sets of data: direct casualties and indirect casualties.

And the seriously wounded, almost equivalent to the dead, and the medical technology that coexisted with the war, until penicillin was discovered, this kind of thing was almost irreversible.

So it's not that the Red Police Corps is cruel, but to let these people get rid of their pain as soon as possible.
