Chapter 1388

Under the wall is the place where zombies are diverted. On the artificially reconstructed ground, various traps emerge in endlessly. A one meter high wall needs to dig a three meter deep ditch to collect soil. A 100 meter long and three meter high wall needs a 200 meter long and a five meter deep ditch. With the help of dozens of excavators and hundreds of construction machinery, there are more than 1000 10 kilometer long walls, The work of tens of thousands of people makes it a more complicated maze than the hot spring base. If it is not for the arrows of various colors on the wall, even the soldiers with wide vision on the wall will get lost.

All kinds of huge trenches are tombs for burying zombies, and the large and small half human high earth walls are landmarks for diverting zombies. Each maze will divert zombies into a huge earth pit from the passageways on both sides of the position. The earth in the earth pit has been taken away for a long time, and the deepest depth is up to five meters, surrounded by earth walls, The steep wall can only climb out above the S3 zombie.

These two earth pits prepared a feast for the separated zombies. Zhang Xiaoqiang asked people to make thousands of burning bottles with a ton of gasoline, just for the zombies in these two big pits.

Of course, all the zombies will not go around the pit. Zombies also have a sense of direction. Once the zombies of type Z2 in the sea of corpses feel wrong, they will turn their attention away and say that they can't make other tangles.

Behind the front position, there is a huge square of 34 square kilometers in the center of the wall. Thousands of one person high gravel pyramids have been piled up in the open space of the square. Under each pyramid, there are cables buried in the ground. Thousands of cables are continuously collected, and finally one cable is collected to connect with a group of electronic starters.

With so much energy and material resources, these gravel pyramids are not used for decoration. In the gathering place, Zhang Xiaoqiang finally found a guy who can make explosives. Among the soldiers of the Yinchuan army and the Frontier Corps, there are a lot of such people, especially Han Yue who came from the special forces and the ghost who came from the mercenaries, Even washing powder can be made into explosives.

Nearly 100 tons of explosives were produced by the explosive factory secretly set up in the rear without anyone's knowledge. Now, nearly half of the explosives are in these gravel piles, and each pile of gravel is buried with various kinds of soil or cutting-edge explosives, TNT, RDX, picric acid, There are even urea explosives and nitroglycerin, the most unsafe.

Thousands of pyramids are 200000 Jin of explosives. Under 10 tons of explosives, Zhang Xiaoqiang can't think of anything that can survive with such power. Besides explosives, Zhang Xiaoqiang concentrates all long-range heavy firepower on the rear of the position.

85 Mm howitzer, 130 mm cannon, 122 mm old howitzer, and 122 mm 40 barrel rocket gun. These guns are one of Zhang Xiaoqiang's family, and a large part of them can't keep up with the transportation force, so they can't guarantee ammunition supply, so they can only be stored in the warehouse.

In the last position, Zhang Xiaoqiang also decided to make a plan of "no family" just in case. There are countless scrap metals buried in the rear wall, and there are countless explosives hidden in these scrap metals. Once the front really fails, Zhang Xiaoqiang will detonate the second half of the position, which is more than ten tons of explosives. Of course, for safety, Until the last step, he will not use it, because if he is not careful, the forces of the four regiments will go to heaven in an instant.

The troops on both sides started one after another. Under the leadership of their respective company commanders, the soldiers of the garrison regiment went to the front position along the half empty bamboo bridge board to fight with the zombies. They didn't have to worry about the zombies' long-range strike, so the soldiers didn't build fortifications on the wall position. At most, they covered the front of the wall with some large nets to prevent S2 zombies from jumping from below.

In front of the corpse sea is still slowly moving forward, Zhang Xiaoqiang is also standing in the front line, rarely accompanied by meow, he holds a telescope to the front of the corpse sea in his eyes.

Zombie sea Zhang Xiaoqiang didn't see it once or twice. Even the soldiers around him had seen a lot. Except for the new recruits, most of the soldiers were calm. If they killed zombies more, they would get used to it.

The soldiers wipe their rifles one after another, insert bullets into the clips, or arrange them on the clip bags around their waists. The front line is filled with the strange atmosphere before the first World War. No one speaks. The soldiers purr their mouths and do their own work. The sound of gun fasteners becomes the main melody in the battlefield.

Zhang Xiaoqiang is also holding a rifle in his hand. All his work has been explained clearly. Any changes on the front are all the affairs of the general staff. He only needs to deal with possible crises in the front, such as zombies of higher evolution.

Like Zhang Xiaoqiang in the gathering place, he used heavy machine guns to clean up D2 zombies. Right beside him, a powerful type 75 14.5mm single barrel heavy machine gun is his killer today. The length of the type 75 anti-aircraft machine gun is about 4 meters, the bottom is supported by a tripod, and the machine gunner sits on the tripod to adjust the shooting direction with the muzzle of the gun.

The 1000 meter range of flat fire is the theoretical distance affected by the horizon. If Zhang Xiaoqiang, who has super long range of sight, can at least guarantee the arc hit rate of 1500 meters, the 80 round drum is a defect. Under the operation of trained professional soldiers, the replacement time can be shortened to the replacement time of the chain of ordinary heavy machine gun.This kind of antiaircraft machine gun was finalized in 81 and equipped in the army in 83. Although it is now replaced by a large number of air defense missile systems, it still occupies a large proportion in the army. In the retired weapons depot of Yinchuan army, Zhang Xiaoqiang found at least 200 type 75 antiaircraft machine guns. If it wasn't for the small number of 14.5mm bullets, there would be no supplement, Zhang Xiaoqiang would like to equip the army with this relatively light antiaircraft machine gun.

So far, only half of these anti-aircraft machine guns have been equipped in the army. The main 1st and 2nd regiments are each equipped with 20 guns, the three garrison regiments are each equipped with 10 guns, the blood wolf brigade is equipped with 15 guns, the blood battle regiment is equipped with 5 guns, and the remaining 10 guns are equipped to the two mountains of Helan gorge.

For the use of such antiaircraft machine guns, almost all troops use the same method to refit pickup trucks into vehicle mounted antiaircraft machine guns. There are four people in a machine gun group, one driver, one co pilot, one machine gunner and one co machine gunner. They are extremely flexible in using antiaircraft machine guns with vehicles. In addition, the vehicles can carry a lot of heavy bullets, So the type 75 14.5mm heavy machine gun is very popular in the army, and it is the most trusted support firepower besides armored vehicles.

Zhang Xiaoqiang felt the new antirust paint on his ice cold gun and turned to look at the front of the wall behind him. There were hundreds of sections of walls around him, which crisscrossed the line several kilometers wide. There was a platoon of soldiers guarding each section of the wall, which was 50 or 60 meters long. There were at least hundreds of walls on the front line, although there were not 36 soldiers on each wall, The two old teams of the garrison division, with a total of 3000 people, were all walking on the walls of the front line.

The soldiers of the garrison regiment are preparing at the first line, while the logistics regiment is waiting at the ammunition supply point of the second line. They will be responsible for transporting ammunition to the front line, collecting cartridge cases, and... Transporting corpses.

As for the long-range firepower, it is all on the third line, at an absolute safe distance of three kilometers away from the front line, and the shells can hit any point several kilometers away at any time according to the needs of the front line.

The soldiers on the wall are ready one after another. Those who can smoke and those who can't smoke all light the special cigarettes for wartime. There are not many. Each person has only three cigarettes, which is their daily supply. The pressure brought by the boundless corpse sea doesn't reflect on their faces, but directly reflects on their inner heart. So they urgently need something to relax themselves.

The two flanking forces have disappeared in the distance. They are going to detour for tens of kilometers and attack on both sides of the zombie sea. Of course, all this will happen after the main position is launched
