The operation of the temporary camp was a far-reaching battle for Zhang Shixin.

Not only did the summoners desperately protect him, but more importantly, Zhang Shixin had a new feeling about tactics.

That is, a single type of tank is counted on as the main force to fight, and many times, if there is a target that cannot be directly opposed, then ...... There is no way to play the same way to end up.

It's just that Zhang Shixin now feels powerless, because he knows that even if there are more tanks, without proper fire support, then this situation will only be repeated again and again.

Although the rewards received in this battle were much more than the losses, especially the two zombie rhinoceros, which almost supplemented the wear and tear that Zhang Shixin encountered in this battle.

He even found out that he had gained the experience of not only being able to directly rush the King Tiger tank to the whole body, but also to upgrade the BT-7 to the T-34-85, or point out a branch of the King Tiger tank - Assault King Tiger.

The Assault Tiger King is a self-propelled gun similar to the Assault Tiger, similar in appearance to the Tiger Hunter tank destroyer, but with a 300mm-STUK46(N)-L25 short-barreled howitzer, weighing about 87.5 tons, and the chassis is an electric transmission model of the later King Tiger model.

One gun plus experience in hull modification equals the T-34-85 missing a semi-complete body of a 100mm gun......

Is it worth it?

Zhang Shixin didn't know very well, but he was severely hurt by the indiscriminate shelling of self-propelled rocket artillery, and after thinking about it again, he still lit up the assault tiger king.

"Is it really good to do that? Maybe it's not as good as you think, and it's not as powerful as the Assault Tiger. Hinia wondered what she knew.

Zhang Shixin shook his head lightly and shook his head: "The Assault Tiger suffers very much in terms of range, can you imagine that the range of a self-propelled mortar gun is only a few hundred meters?" Well, if the other side has the ability to break through my first defensive line, then the Assault Tiger is the first target to be hit. Moreover, the loading speed of the Assault Tiger actually takes two minutes, and with this time to shoot a few shells, it is estimated that the self-propelled rocket launcher can plow the ground twice without panting. The most important problem is that the barrel of the Assault Tiger's 380mm gun is too short, and the paper accuracy of 100 meters is actually 1.7...... It is estimated that it is time for several No. 4 'Leopard G' equipment types to go to hell en masse. ”

Zhang Shi thought for a moment, and then said: "The power of the assault Tiger King is not as great as the Tiger King, but the range of about 2500 meters is enough in many battles, and the rate of fire of 1.3 minutes is still a very serious problem for the time being." However, technology can be used to make up for this shortcoming in the future. The accuracy is OK, 100 meters accuracy is 1.14, as long as it is not too bad luck, it is a bit difficult to smash your own people. On top of that, his combat ammunition base is 12 rounds (three rounds in the hull and nine rounds in the heavy artillery loading crane), which is much better than the pitiful five rounds of the Assault Tiger's 380mm shells. ”

"Even if it's really a flaw in terms of power, it's better to just pursue power than to be average." Zhang Shixin made his own summary.

Sinia didn't say anything, because she felt that Zhang Shixin might be right. After all, he can still feel some of the other party's psychological fluctuations.

As a result, Zhang Shixin's convoy added three King Tiger tanks equipped with 105mm tank guns and three assault King Tiger self-propelled guns.

For the Tiger style and Tiger P, Zhang Shi thought about it again and again, and still supplemented the Tiger P, after all, it can be modified accordingly. For the Tiger tank, Zhang Shixin still gave up the idea of supplementing, although the long 88mm tank gun can still meet the operational needs. However, the combat needs of the Tiger itself are too bad, although the mobile surname is not bad, but the disadvantages in terms of protection have become more and more obvious.

In addition, the Tiger P can be converted into a self-propelled gun, a tank destroyer (Ferdinand/Elephant), and the Tiger tank can be converted into a self-propelled rocket launcher and an Assault Tiger.

Although Zhang Shixin wants to know how much the difference between the power of 150mm rockets and 132mm rockets is, if it really needs to be verified in actual combat, Zhang Shixin cannot guarantee how much Tiger Tank he has to reimburse before he can draw relevant conclusions.

The strongest self-propelled gun in Germany is the P-1500R, which was modified by two sisters, equipped with a 600mm-SFH48(N)-L50, the chassis is a thing that lengthens the body length and lowers the body, and there are 15 pairs of load-bearing wheels alone.

Its weight is not as heavy as the Rat Ge, only 163.7 tons, which is much heavier than the Karl self-propelled mortar gun, but most of the increase is the modified chassis reinforcement weight, and the weight of the gun itself is a little lighter than that of the gun carried by the Karl self-propelled mortar gun.

Zhang Shixin knew that the biggest problem with Doramm's 800mm gun was not the weight, but the recoil, but Zhang Shixin didn't take this thing too seriously, because when the modified P-1500R came out, Zhang Shixin probably used that electromagnetic booster gun technology to arm himself.

For example, if the shell fired by the 600mm-SFH48(N)-L50 cannot be pierced by electromagnetic pressurization in the case of direct fire, it is estimated that the shell of the 800mm gun will not have much effect.

Of course, if you shoot warp, it will be difficult for Shang Yanjing to hold an 800mm shell, and if this thing is a concrete armor-piercing projectile, it is estimated that the Yamato ship will be smashed in pairs......

As for power...... For example, if you use a special high-explosive shell, the 800mm shell is estimated to be able to survive even if it is 100 meters away, what 99g, what m1, few of the crew can survive.

If it's a 10-meter range...... No one knows how many more parts will be found on site.

The problem is, this thing is a railroad gun, if the chassis of an armored tank is ...... Brother Rat had to fall apart with a single shot.

Unless it's really the chassis of the P-1000, it's still fine, but can the P-1000 move on its own?

The problem of suspension is not a problem, the problem is that tens of thousands of tons of weight are pressed on the ground, and you can find a moving road surface?

So, the P-1500R is the limit of the self-propelled artillery system...... Caliber, of course.

Brother Rat can also be converted into a tank destroyer and self-propelled gun, and because of the weight reduction (Brother Mouse's turret also has dozens of tons), the VK-10001/250PE "Assault Mouse" is similar to Brother Rat in terms of armor protection, but it is equipped with a 210mm-PAK48(N)-L55 anti-tank gun, which is the strongest tank destroyer in Germany.

And the speed has also increased to a certain extent.

But Zhang Shixin was very curious about whether this thing, with its estimated size of 13 to 14 meters, would be useful in street fighting.

As for the self-propelled guns, the long-barreled howitzer of the gwww.xstxt.orgm-SFH48(N)-L42, as for the armor, a small reduction was made due to the reinforcement of the chassis, and at the same time, due to the placement of the gun in the rear of the hull, the engine was moved to the middle, and a large movable shovel was added behind the hull to reduce recoil.

But the above things, Zhang Shixin probably didn't expect to be able to use them for a long time, first, the experience required is massive, and second, these higher-level weapons also require higher military ranks to be unlocked.

For example, GW "Rat" requires the rank of Lieutenant General to unlock. The P-1500R requires the rank of general to unlock.

As for what the rank of marshal unlocks?

Zhang Shixin wanted to know, but Sinia didn't answer Zhang Shixin, but said that you will know the prevarication when the time comes.

So now, compared with weapons that are still far away, Zhang Shixin is more concerned about the situation of this catastrophe.

These zombie beasts are not local products, they should be the products of this space brought by the destruction of the other world. Because in the western part of the continent, there is no such thing as a rhinoceros.

It is clear that these things are not present around here......

Or rather, they were in this place.

Two diametrically opposed conclusions...... Isn't that a contradiction?

It doesn't have to be contradictory, but it depends on one point.

That is, it depends on what kind of building is the source.

Moreover, with the movement of the zombie rhinoceros, it is impossible for the Hilton Army not to react at all, at least on the surface of the land, which is not easy to hide from the past.

But if there is a passage underneath the town, then everything is well explained.

The big pit is stuck diagonally into the ground, if there is no accident......

"Oops!" Zhang Shixin suddenly remembered a terrible possible surname - a large subway network.

Compared with a one-way or two-way source, the subway network with several exits is more troublesome.

Even if the former can't be defeated, it can be blocked, but this kind of ghost place can't be blocked.

He hurriedly sent two M20 universal armored vehicles with glow-in-the-dark devices to reconnoiter the situation.

And he was communicating with Schumak.

……………………………………………… Dividing Line................................................

A few hours later, Zhang Shixin persuaded the commander of the Hilton Army to enter the nearby passage overnight to investigate.

Zhang Shixin found that he really said a little bit, there was really a subway network underground, but even after the investigators of several troops penetrated into a certain range, they still didn't find anything abnormal, except for ......

Numerous abandoned debris and some bones that had turned dark brown.

Zhang Shixin naturally knew where those bones came from, they were the bodies of the refugees.

Obviously, that space was destroyed by a biochemical disaster.

And because of the staggering of this space, these things will appear in this world.

However, unlike the Earth, this subway network can also be used as a road.

Because the track is not a convex track, but a concave track. And the space is much larger than the tunnels on Earth.

Zhang Shixin sat in his new car, and then watched as the teams of infantry protected by the two wings of the armored car slowly entered the tunnel.

And he sat inside the King Tiger tank, as the first batch of heavy armored troops, entered inside.

For self-propelled guns, Zhang Shixin only brought all the wild bee self-propelled guns as flare projectors into the inside, and the others stayed outside to guard the entrance of the cave.

He wasn't worried about the Hilton Empire's people being bad, because he found that the opponent's self-propelled guns were no less than the ones he had now, except for their speed and the power of their shells.

So he was still more comfortable leaving the self-propelled guns on the ground.

No matter how bad it is, Zhang Shixin's weapons and equipment all use self-detonation systems, and he is not worried that his weapons will be snatched away.

In order to make up for the lack of heavy firepower, Zhang Shixin re-issued a 100mm caliber tank killer as a firepower supplement, as for the effect, to be honest, Zhang Shixin did not have much accuracy.

However, it is much better than not having a coping weapon.

……

The troops operating at the same time as Zhang Shixin's Elven Dragon Security Company also had several Hilton troops that had discovered similar passages, and if Zhang Shixin's conjecture was correct, they would meet face-to-face after a period of time.

As for how big this subway network is, Zhang Shixin didn't find any map drawings, everything in the subway was seriously damaged, and even some abandoned subway cars were knocked to the side, Zhang Shixin estimated that it should be the good deeds done by the two zombie rhinoceros.

After entering the underground railway tracks, Zhang Shixin estimated that this place was about twenty-five meters away from the ground, no wonder the entire camp would suddenly be wiped out, and at this distance, the ground could not hear much movement. It's true.

Moreover, he was curious that the entrance to the passage was in the town square, which had not collapsed for decades, and it was really a miracle.

Forget it, it's not something to focus on.

According to the original plan, Zhang Shixin and the Hilton armored troops who rushed to support were divided into two routes, and each side set off in one direction. If they came across a fork in the road, they called in other troops to come to their aid.

Zhang Shixin chose a road to the north, and the convoy slowly moved forward under the cover of the infantry, relying on the illumination of the flares.

At the front of the convoy were three M20 general-purpose armored vehicles, which were responsible for directing the Wild Bee self-propelled guns to fire flares and alerting them to possible contingencies ahead.

As for Zhang Shixin's King Tiger tank, it was slowly moving forward in the front row of the convoy.

Zhang Shixin felt the occasional slight jump of the King Tiger Tank while driving, and he knew that this was the situation when the tracks of the King Tiger Tank crushed some bones. But he didn't pay much attention, because the passage was really quiet and quiet, and he didn't hear anything other than the roar of the engines of armored vehicles and the slight sound of bones shattering.

"It was so quiet. And...... According to the agreement, the other party should also send someone to search for it. Zhang Shixin observed this situation in the periscope, and was very uneasy.

Because according to his understanding, there should be light ahead.

But now it's still pitch black.

"Let the two M20s turn on their headlights, quickly reconnoiter the situation ahead, don't fall in love when you encounter danger, and return immediately!" Zhang Shixin made this decision.

Two M20 general-purpose armored vehicles immediately rushed out, and the team continued to move slowly.

What Zhang Shixin didn't know was that except for a few teams, many teams were in trouble......

……

"Fire !!" The commander of the Hilton Army had to command his troops to put up desperate resistance.

"Sir!! There are too many of them, and we can't resist them!! The adjutant had to shout loudly, and then he raised his pistol and shot at the other side.

"Ask for help! Fast!!! The commander shouted loudly, then raised his submachine gun and fired.

The distress signal was issued, but a few minutes later, the last soldier to retreat into an armored vehicle watched helplessly as the zombie with a dark blue glow in his eyes easily tore open the locked rear armored door, and had to raise his weapon against his chin......

"Pong!"

The gunshots were quickly drowned out by the roar of zombies......

And the Hilton Imperial officers and soldiers who were bitten to death slowly got back on their feet soon after......

And where this team is, use a passage to lead to the area below......

This is where the dense hordes of zombies flock in......

……

"......" After receiving the distress signal from the Hilton Army, Zhang Shixin took a deep breath, and then after comparing it on the map for a while, he found that a few kilometers ahead was exactly where one of the troops was located.

"The subway intersection ......" Zhang Shixin reluctantly confirmed this fact. The zombies on this level ran to the ground to play, but the ghosts below also ran up.

Isn't that bullying?

Zhang Shixin had to order the troops to separate the two sides and guard the front and back, and then wait for the two M20 general-purpose armored vehicles to return.

At the same time, he thought of a terrible thing, and that was a subway network with subway intersections, something that only large cities have.

What is more in a large city?

Most people......

All right......

Zhang Shixin found a very serious problem, that is, it is not possible to make the zombie group below more than the above combined......

Weapons and ammunition, special equipment......

Zhang Shi worked hard with all his heart.

Zhang Shixin purchased all the machine guns and machine guns, and on average, each person could get a machine gun that could be loaded with a large chain box.

As for other weapons, Zhang Shixin still didn't plan to purchase them, because in this case, he also used flame weapons on a large scale, and in the case of blocking at both ends, it is estimated that within a few minutes, everyone will die of lack of oxygen.

If you play with fire too much in this kind of space, it is easy to suffocate everyone inside.

So Zhang Shixin confiscated all weapons such as Molotov cocktails, and then distributed machine gun bullets as much as possible.

Even if it was used as a cover, everyone was surrounded by large chain boxes full of them.

Of course, just in case, Zhang Shixin still arranged for a considerable number of flamethrowers and hemorrhage to buy several large exhaust fans.

……

All commanders were armed with machine guns, ready to fire at any time on the turret.

And two M20 universal armored vehicles returned, and the machine-gun shooters were still firing in the back with their assault rifles.

Zhang Shixin knew that there was something behind him chasing after him, so that the machine gun shooter was shooting in this situation.

He heard the barking of dogs in the depths of the dark passage......

"Your sister! Zombie dogs?! Zhang Shixin naturally knew what the hell this was, but he was surprised that there were not a few of these zombie dogs, and they were very fast, otherwise, these two M20 general-purpose armored vehicles would not have fled like this.

"Shooting !!" Zhang Shixin waited until the members of the M20 general armored vehicle jumped out of the car and ran towards the defensive position, and then quickly issued a design order.

Once again, the battle began with the sound of heavy machine-gun fire and the mournful screams of many of the zombie dogs that had been hit......
