Below the top of the wall is the place where the zombies are diverted. On the artificially modified ground, various traps emerge in endlessly. A one-meter-high earth wall needs to dig a three-meter-deep trench to collect soil. A hundred-meter-long and three-meter-high wall requires The 200-meter-long and 5-meter-deep ditches, under the action of dozens of excavators and hundreds of construction machines, have more than a thousand walls of 10 kilometers long. The labor of tens of thousands of people has made this place more complicated than a hot spring base. If it weren't for the arrows of various colors on the wall, even the soldiers with a wide view on the wall would get lost.
All kinds of huge ditches are graves for filling zombies, and large and small half-person-high earth walls are beacons for diverting zombies. Mazes will divert the zombies pouring into the position, and enter a tunnel from the passages on both sides of the position. A huge earth pit with a radius of one kilometer. The soil inside has been removed long ago. The depth is as deep as five meters. There are earth walls on all sides. Only small zombies can climb out of the steep earth walls.
These two pits prepared a feast for the diverted zombies. Zhang Xiaoqiang had someone make thousands of Molotov cocktails with one ton of gasoline, just for the zombies in these two big pits.
Of course, all the zombies won't go around into the big pit. Zombies also have a sense of direction. Once the Z-shaped zombies in the corpse sea feel that something is wrong, they will divert their attention, and there may be other entanglements.
Behind the forward position, there is a huge square of three to four square kilometers in the center of the wall. In the open space of the square, thousands of crushed stone pyramids with a height of one person have been piled up. Under each pyramid, cables are buried underground. The root cables are continuously brought together, and finally a cable is gathered to connect with a group of electronic starters.
After spending so much energy and material resources, these gravel pyramids are naturally not for decoration. Zhang Xiaoqiang finally found a guy who can make explosives in the gathering place. Among the soldiers of the Yinchuan Army and the Border Guard Regiment, such a talent was caught A lot of them, especially Han Yue from special forces and Ghost from mercenary, can even make washing powder into explosives.
Nearly one hundred tons of explosives were produced by the explosives factory secretly set up in the rear without anyone knowing, and became one of the guarantees to support the frontline operations. Now, nearly half of the explosives are in these rubble piles. All kinds of soil or sharp explosives, black gold, picric acid, and even urea explosives and unsafe nitroglycerin are buried in the gravel.
Thousands of pyramids are 200,000 catties of explosives. Under ten tons of explosives, Zhang Xiaoqiang can't think of anything else that can survive under such power. Apart from explosives, Zhang Xiaoqiang concentrated all his long-range heavy firepower on rear of the position.
Millimeter howitzers, millimeter cannons, millimeter old-fashioned howitzers, and millimeter 4-barrel rocket launchers. These cannons are one of Zhang Xiaoqiang's assets. There are still a large number of cannons that cannot guarantee ammunition supplies because of the transportation force. stored in the warehouse.
In the rear position, just in case, Zhang Xiaoqiang made a desperate plan. Countless scrap metals were buried in the rear walls, and countless explosives were hidden among the scrap metals. Half of the position was detonated, which was more than ten tons of explosives. Of course, for the sake of safety, he would not use it until the last step, because if he was not careful, the strength of the four regiments would go to the sky in an instant.
The troops on both sides spread out one after another. Under the leadership of their respective company commanders, the soldiers of the garrison regiment set up the forward position along the bamboo bridge plank in mid-air to fight against the zombies. There was no need to worry that the zombies would use long-range attacks, so the soldiers did not stand on the top of the wall. To build fortifications, use more large nets to cover the front of the wall to prevent zombies from jumping up from below.
The sea of corpses in front was still slowly moving forward, Zhang Xiaoqiang was also standing on the front line, it was rare that there was no Meow Miao by his side, he held up the binoculars to keep the forward of the sea of zombies in his eyes.
Zombie Sea Zhang Xiaoqiang didn't arrive once or twice, even the soldiers around him had seen many of them. Except for the supplementary soldiers who came, most of the soldiers were very calm. Zombies killed a lot, so naturally Just get used to it.
The soldiers cleaned their rifles one after another, stuffed bullets into the clips, or packed the clips around their waists. The front line was filled with a strange atmosphere before the war. No one spoke, and the soldiers pursed their mouths. Everyone was doing their own work, and the sound of gun fasteners became the main theme on the battlefield.
Zhang Xiaoqiang also holds a rifle in his hand, and he has clearly explained all his work. Any changes on the front line are all the responsibility of the staff department. He only needs to deal with possible crises ahead, for example, advanced evolved zombies.
Just like Zhang Xiaoqiang used a heavy machine gun to clean up the group of d zombies in the gathering place, right beside him, a mighty Type 4.mm single-barreled heavy machine gun is his trump card today. Supported by a tripod, the machine gunner sits on the tripod and adjusts the shooting direction with the muzzle.
The flat shooting distance of 1,000 meters is a theoretical distance affected by the horizon. If Zhang Xiaoqiang, who has a super long-sighted range, can at least guarantee an arc hit rate of 1,500 meters, ten bullets is a defect. Under the operation of soldiers, the replacement time can be shortened to the replacement time of the bullet belt of ordinary heavy machine guns.
This anti-aircraft machine gun was finalized in 2010 and equipped with troops in 2011. Although it is now replaced by a large number of anti-aircraft missile systems, it still occupies a large proportion in the army. Zhang Xiaoqiang found at least two hundred anti-aircraft machine guns in the decommissioned arsenal of the Yinchuan Army. If it weren't for the fact that the number of 4.mm bullets was not much, and there was no replenishment after emptying them, Zhang Xiaoqiang could not wait to equip all the relatively light anti-aircraft machine guns to the troops.
So far, only half of these anti-aircraft machine guns have been equipped in the troops. The first and second regiments of the main force are equipped with 20 each, the three garrison regiments are equipped with 10 each, the blood wolf brigade is equipped with 15 guns, and the blood battle regiment is equipped with 5 guns. The ten stalwarts were equipped on the two hills of the Helan Canyon.
For the use of this anti-aircraft machine gun, almost all troops use the same method, using a pickup truck to convert it into a vehicle-mounted anti-aircraft machine gun. A machine gun team consists of four people, a driver, a co-pilot, a machine gunner, and a sub-machine gunner. The anti-aircraft machine gun used by the vehicle is extremely flexible, and the vehicle body can carry a lot of heavy bullets, so the Type 4.mm heavy machine gun is very popular in the army, and it is a trusted support firepower besides armored vehicles.
Zhang Xiaoqiang touched the anti-rust paint on the body of the ice-cold gun, and turned his head to the wall position behind him. There are hundreds of sections of walls around, criss-crossing and covering a few kilometers wide line, and each section is 50 to 60 meters long. There is a row of soldiers guarding the walls. There are at least hundreds of walls on the front line. Although not every wall has thirty-six soldiers, the two veteran regiments of the garrison have a total of 3,000 people, but they all walk on the front line. on each wall.
The soldiers of the garrison regiment are preparing on the front line, and the logistics regiment is waiting at the ammunition supply point on the second line. They will be responsible for delivering ammunition to the front line, collecting shell casings, and... transporting corpses.
As for the long-range firepower, they are all distributed on the third line, at an absolute safe distance of three kilometers away from the front line, and shells can be fired at any point several kilometers away at any time according to the needs of the front line.
The soldiers on the fence finished their preparations one after another. Those who could smoke and those who could not smoked lit the wartime special cigarettes. Not many, each person only had three, which was their daily supply. The pressure brought by the boundless sea of corpses did not respond. Their faces speak directly to their hearts, so they desperately need something to relax.
The two flanking troops had disappeared into the distance. They were about to detour tens of kilometers and start attacking on both sides of the zombie sea. Of course, all of this had to be done after the main position was launched.
