Under the wall is the place where the zombies are diverted. On the artificially modified ground, various traps emerge in an endless stream. The one-meter-high earth wall needs to excavate the three-meter-deep ditch to take the soil. The 100-meter-long, three-meter-high wall needs Two hundred meters long and five meters deep ditches, with the effect of dozens of excavators and hundreds of construction machinery, the ten-kilometer-long wall is more than a thousand. The work of tens of thousands of people makes this more complicated than the hot spring base. The maze, if not the arrows of various colors on the fence, even the soldiers with wide vision on the fence will get lost.

All kinds of huge trenches are graves for landfilling zombies, and the earthen walls of large and small and half-high are the road signs for diverting zombies. The fans will divert the zombies that flow into the positions and enter the channel from the sides of the positions. The huge earthen pit, the earthen pit is about a thousand meters, the soil inside has long been taken away, the deepest depth is five meters, the earth wall is surrounded by all sides, and the steep earth wall can only climb out if it is more than S3 zombies.

The two pits prepared a feast for the diverted zombies. Zhang Xiaoqiang made thousands of burning bottles with one ton of gasoline, which was prepared for the zombies in the two pits.

Of course, all the zombies will not be wrapped around the crater. The zombies will also have a sense of direction. Once the Z2 zombies in the corpse feel wrong, they will turn their attention and say that they will not make any other tangles.

After the front position, there is a giant square of three or four square kilometers in the center of the wall. Thousands of high-rise gravel pyramids are piled up in the open space of the square. Cables are buried underground under each pyramid. The root cables are continually assembled and eventually assembled by a single cable that is connected to a set of electronic starters.

It takes so much energy and material resources that these gravel pyramids are not used for decoration. Zhang Xiaoqiang is in the gathering place, and finally finds a guy who can do explosives. Among the soldiers of the Yinchuan Army and the border guards, such talents are caught. A large number, especially the special squad of Han Yue and the mercenary-born ghosts, even the washing powder can be made into explosives.

Nearly one hundred tons of explosives were produced by a secretly established explosives factory without anyone knowing it. It has become one of the guarantees for supporting forward operations. Now, nearly half of the explosives are in these gravel piles, each pile. The gravel is buried with various earthy or new explosives, TNT, black gold, picric acid, and even urea explosives and the most unsafe nitroglycerin.

Thousands of pyramids are 200,000 kilograms of explosives. Under ten tons of explosives, Zhang Xiaoqiang can’t think of anything. There is still something that can survive under such power. In addition to explosives, Zhang Xiaoqiang concentrates all the long-range heavy firepower. Behind the position.

85mm howitzer, 130mm cannon, 122mm old-fashioned howitzer, and 122mm 40-barrel rocket. These cannons are one of Zhang Xiaoqiang's homes. There are still a large number of cannons that cannot be used because of the transportation power. The grievances are stored in the warehouse.

In the final position, Zhang Xiaoqiang also set a homeless account in case of accidents. The rear walls are all buried with countless scrap metal. There are countless explosives in the scrap metal. Once the front line is really lost, Zhang Xiaoqiang will The half-cutting position was all detonated, which is more than ten tons of explosives. Of course, for safety, he will not use it until the last step, because if you are not careful, the strength of the four regiments will go to heaven in an instant.

The troops on both sides began to unfold. The soldiers of the garrison, under the leadership of their respective company commanders, took the front position along the bamboo bridge in the air and battled the zombies. There is no need to worry that the zombies will use long-range strikes, so the soldiers are not on the wall. Construct fortifications, cover up the front of the wall with some large nets to prevent S2 zombies from jumping from below.

The corpse sea in front is still moving forward slowly. Zhang Xiaoqiang is also on the front line. He is not surrounded by him. He holds the telescope and puts the zombie's forward in his eyes.

The zombie sea Zhang Xiaoqiang did not see it twice, even the soldiers around him had seen a lot. In addition to the new recruits, most of the soldiers performed very calmly, and the zombies killed so much. Naturally, I am used to it.

The soldiers wiped the rifles, stuffed a bullet into the magazine, or put it on the waist of the magazine. The front line was filled with a strange atmosphere before the war. No one spoke, the soldiers pouted. Each of them is doing their own work, and the sound of the gun fasteners becomes the main theme in the battlefield.

Zhang Xiaoqiang also holds a rifle in his hand. All his work is clearly explained. Any changes in the front line are all matters of the staff. He only needs to deal with possible crises in the forefront, for example, the evolution of zombies.

For example, Zhang Xiaoqiang used a heavy machine gun to clean up the D2 zombie group at the gathering place. Just beside him, a mighty 75-type 14.5 mm single-barrel heavy machine gun is his killer today. The 75-type high-altitude machine gun has a gun length of about 4 meters. The bottom is supported by a tripod, and the machine gunner sits on a tripod to adjust the firing direction with the muzzle.

The horizontal distance of one kilometer is the theoretical distance affected by the horizon. If it is replaced by Zhang Xiaoqiang with super-far distance, at least the arc hit rate of 1,500 meters can be guaranteed. Eighty rounds of drums are a defect, after training. Under professional soldiers' operation, the replacement time can be shortened to the replacement time of the ordinary heavy machine gun chain.

This high-altitude machine gun was finalized in 81 years and equipped with troops for 83 years. Although it has been replaced by a large number of air defense missile systems, it still occupies a large proportion in the military. In the retired arsenal of Yinchuan Army, Zhang Xiaoqiang has found at least two hundred and 75. High-altitude machine guns, if not because the number of 14.5 mm bullets is really small, no need to add empty, Zhang Xiaoqiang can not afford to equip this relatively light high-altitude machine guns to the troops.

So far, only half of this high-altitude machine gun has been equipped to the army, the main force one or two groups each equipped with 20, the three garrison groups are equipped with ten, the blood wolf brigade equipment is fifteen, the blood battle group equipment five, the rest Ten of them are equipped to the two hills of Helan Canyon~lightnovelpub.net~ For the use of such high-altitude machine guns, almost all units use the same method, using pickups to convert into high-altitude machine guns, a machine gun group of four people. , a driver, a co-pilot, a machine gunner, and a sub-machine gunner. The use of high-altitude machine guns is extremely flexible, and the vehicle itself can carry a lot of heavy bullets, so the 75-type 14.5-mm machine gun is very much in the army. Popular, it is the most trusted support firepower except armored vehicles.

Zhang Xiaoqiang touched the new anti-rust paint on the cold gun, turned his head to look at the wall behind him, and there were hundreds of walls around it, criss-crossing the lines along the width of several kilometers, each of which was fifty or sixty meters long. There are a row of soldiers guarding the fence, and there are at least a hundred walls on the front line. Although not every 36 fences are there, the two old teams of the guards have a total of 3,000 people walking in the same line. On the various walls.

The soldiers of the garrison are preparing in the first line, and the squad is waiting for the second-line ammunition replenishment point. They will be responsible for transporting ammunition to the front line, collecting the shells, and transporting the bodies.

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

The soldiers on the fence are ready to go. The ones who will smoke and not smoke will ignite the special cigarettes for wartime. There are not many cigarettes. There are only three of them. It is their daily supply. The pressure from the boundless sea is not reflected. Their faces directly reflect their innermost feelings, so they urgently need something to relax.

The two side-strike troops have disappeared into the distance. They will have to take back dozens of kilometers and start attacking on both sides of the zombie sea. Of course, all this will happen after the main position is started.
