In the camp, there are not even many off-road vehicles, and the total number of troop carriers, material vehicles, and medical vehicles is less than 20.

All of this equipment added up did not even exceed 50 amounts, which is really a bit stretched for a regiment's material reserves.

So much so that they didn't even bother to build roads.

At this time, after the tank was crushed back and forth uphill, the original sturdy mountain road became loose, and the buildings and roads that were not very dilapidated before were now in tatters.

"Squadron Leader! Level 5 Zombies! \"

At this time, all of a sudden, a team member shouted at Zhang Kaiyuan, and then the team member pointed in the direction of the distance, and with the person's finger, Zhang Kaiyuan also looked over,

I saw that the fifth-level zombies had been freed from that position at this time, and the place that had besieged them like a swamp had been completely broken away by the fifth-level zombies at this moment.

With the expansion of the ravine, the zombies behind him were also taken off by the invincible zombies, and the third-level zombies who were holding the ankles of the invincible zombies on the ground were actually taken off by the fifth-level zombies like a horse bag.

More than a dozen or even more third-level zombies were dragged up by the fifth-level zombies, you can imagine how powerful the power of the fifth-level zombies is, you must know the weight of a third-level zombie, which is equivalent to the weight of 300 catties.

Ten third-level zombies are almost more than 3,000 catties, and the weight of more than 3,000 catties is equivalent to the weight of a car, and the volume of a fifth-level zombie and its strength make it easy to drag a car.

Seeing that those fifth-level zombies had already rushed to their previous defensive position, the simple chest cavity stacked in front of the defensive position was kicked by the fifth-level zombies in the blink of an eye.

After those third-level zombies were dragged out of the swamp by the fifth-level zombies, they also barely stood up, but on the mountain peak on the right, some agile bear zombies finally rushed over, and the zombies on the left also rolled down the hillside.

The zombie army finally formed a torrent, and with this torrent, the scale of the zombies suddenly occupied the entire valley, and they finally returned to the state of attack before,

Well, Zhang Kaiyuan took his own team, and the foundation they laid down was reoccupied by the zombies, but this time the zombies' offensive was obviously more fierce than before.

In the previous zombie group, there were not so many evolved zombies, and now there are countless zombies stacked at the mouth of the entire valley, including fourth- and fifth-level zombies, as well as second- and third-level zombies, these zombies are from the middle of the valley and the slopes on both sides.

The zombies divided into several offensive lines and rushed towards them, like a tide of magma, engulfing everyone in front of them, but if anyone was caught by them, then the end would be extremely miserable.

So that everyone understands that the environment they are currently in is not the safest, and they may be overwhelmed and torn apart by zombies at any time, and no one doubts that the zombies in front of them are a torrent that they cannot shake at present.

A group of people ran leisurely to the back, except for the people sitting on tanks and armored fighting vehicles, infantry fighting vehicles, and off-road vehicles, all of whom were members of the Special Operations Corps.

The first reason is that they take care of their vehicles, and the other reason is that Zhang Kaiyuan did not order them to give up their equipment, if the order is given, then even if Zhang Kaiyuan does not urge, this group of people will rush into the defensive position.

This is the execution of their team, and Zhang Kaiyuan doesn't need to worry about the execution of the special operations legion at all, so the members of the special operations legion stay as cover for the retreating personnel.

Under Zhang Kaiyuan's urging, the second temporary defensive formation had been re-established in the crowded position on the hillside, and the defensive shaping established here was a last resort, because the tanks behind had collapsed the road. Swap

The barrel of the tank, including the smoothbore gun in the rear, the heavy machine gun infantry fighting vehicle, and all the weapons were aimed at the level 5 zombies rushing towards them.

\"All artillery fire is prepared, and all heavy armor is aimed at the zombie hordes except tanks,\"

Then with the sound of the clockwork, all the equipment turned to the direction of the mouth of the valley, and the zombies also swarmed in from that direction, and at the same time as the zombies poured in, the infantry fighting vehicle took the lead in firing, because it was a heavy machine gun, so the infantry fighting vehicle would not cause the vibration of the mountain to be too huge.

\"Dada! \"

The anti-aircraft machine gun installed above the infantry fighting vehicle, this anti-aircraft machine gun, basically all of which are 15.6 mm bullets, this high-strength armor-piercing projectile, can penetrate the thick armor of the armored vehicle, and even some light tanks can easily penetrate.

There are also some air-flying units, such as helicopters, which can also rely on this equipment to shoot down helicopters, and his main purpose is actually air defense, to guard against some drones in the air and air combat units.

In addition to the height of the fighter, there are some other raptor-like attack helicopters, and the other helicopters are basically able to shoot down with the high-value equipment of this infantry fighting vehicle.

So it is more than enough to deal with these zombies in front of them, before these anti-aircraft machine guns, when they shot the third-level zombies, the third-level zombies were basically irresistible, upgrading the thick muscles of the zombies, and the ordinary rifle bullets could also resist it, but under the intensive shooting, the third-level zombies would also be killed by the rifle bullets.

What's more, this kind of anti-aircraft machine gun, and the anti-aircraft machine gun on the infantry fighting vehicle, has been transformed, and the power of the anti-aircraft machine gun has been increased by more than two times, which is still not integrated into the situation of Hextech.

\"Knock knock! \"

The bullets of the anti-aircraft machine gun swept over the body of the third-level zombie, making a dull explosion sound, the sound of this explosion, as if it had broken a small drum, and with the explosion of the sound, the zombie's body also continued to burst out of black blood mist.

At the same time as the blood mist was dissipated, everyone saw that the zombie in front of them had turned into a broken sack, and the body was full of blood holes, but the anti-aircraft machine gun did not stop, and the zombie fell at the same time, regardless of whether it was dead or alive, as long as it fell, it would not be ignored, and then the muzzle of the anti-aircraft gun would be raised, aiming at the next moving zombie.

When aiming at the zombie, the flames of the anti-aircraft machine gun will spit out again, and the second third-level zombie will fall under the muzzle of the gun.
