Dai Peng circled around the trailer for a few times. In his opinion, this must be a guy who was much larger than a jackal light tank, especially the long gun barrel. It was clearly a tank, and the random battlefield repair cars and ammunition trucks also explained the problem.

The convoy was a young chef. After asking Dai Peng that the chef was named Lu Yu, who was directly under the special armored force of the war zone. They were a passing test force. Because of the blizzard, they were delayed in Chaoyang and placed on what mission they performed. Lu Yu, who had a smile on his face, did not reveal a word, so he left Dai Peng with an impression of a bad guy without telling the truth: []

In fact, Lu Yu's test team is responsible for transporting a high-intensity mountain marching and combat, inspecting the new load-bearing wheel test escort team, six jackal light tanks in the entire company, plus a command vehicle, three accompanying ammunition trucks and two full-function terrain vehicles. The so-called full-function terrain vehicles are one and a large armored vehicle, which can be used for eight people to live in. However, the two large full-function terrain vehicles escorted by Lu Yu, "one car has three male engineers" and two female heavy-load design researchers. Living in the car is much warmer than living in a house in the military camp, and the bathroom is complete. Lu Yu is naturally envious of the treatment of scientific researchers. However, technology is the first combat power, as long as the cavalry completes various improvements and tests as soon as possible, that is Lu Yu's happiest thing. Although the jackal light tank has outstanding performance, it is still a light tank.

In the minds of truly armored soldiers, the steel torrent refers to medium and heavy tanks. The rolling steel torrent quietly crushes all enemies who dare to provoke?

However, the heavy snow and difficult roads hindered Lu Yu's retreat plan. The First Guard Division was the only one among the garrison troops, which strengthened a well-prepared brigade, and the rest of the divisions were established in the second brigade and the fourth regiment. Even so, the second heavy fortress artillery group of Chaoyang garrisons and the defenders were all over 19,000, which was a small force. Now all personnel have participated in the snow removal operation in Chaoyang City.

In the eyes of poets, the snow may be Lanli, but in the eyes of the common people, heavy snow means disaster. Livestock are frozen to death. "Houses are crushed by heavy snow." Residents in more than 20 residential areas near Chaoyang are gathering in Chaoyang City at this moment. Dai Peng, as the commander of Taobei, also prepared a large amount of food and resettlement locations.

Chaoyang is a famous historical and geographical city. It has been established since the Western Han Dynasty. Chaoyang was called the western part of Liaoning in ancient times. Because it is located in an ancient transportation link from the Central Plains to the Northeast, historical ethnic activities are in the link between the Han people in the Central Plains and the ethnic minorities in the Northeast. Therefore, all dynasties in the Central Plains have set up important border towns here. When the Northeast ethnic groups entered the Central Plains, they should also regard it as a place to compete for, making Chaoyang a strategic place outside the Frontier in all dynasties.

The surface of Chaoyang is covered with mountains, hills, canyons, and ravines. Only small pieces of plain land between the mountains and rivers hit the plains. The structure is a typical area of ​​seven mountains, one water and two fields.

However, Chaoyang has rich mineral resources, especially mineral resources with wide distribution, many types and great development potential. At present, more than 50 beneficial minerals have been found in the country, with more than 50 production areas. It has proven reserves of manganese rank first in the northeast, and copper production ranks second in the country. It is one of the eight largest gold production areas in the country.

Therefore, when Zhang Xuewu had a counterattack in Chengde, he first ignored the actual situation at that time and resolutely drove the remnants to forcibly fight Chaoyang. Then he immediately began to build Chaoyang Fortress. Now, the city of Chaoyang is basically dominated by miners, family members and construction machinery and miners.

In addition, since the end of the Battle of Lengnian Rehe, the national defense fortifications personally led by Zhang Xuewu of Chaoyang has never stopped. It has been built on a large amount of manpower and material resources. Including the Japanese siege, Chaoyang's fortifications did not relax at all.

The overall layout of Chaoyang Fortress city is to use the original city walls to pile up earth and stone in the city area along the Daling River to create a five-kilometer-long and thirty-meter-wide defensive isolation belt. The bluestone accumulation and concrete casting method are used to dig underground bunkers and passages below, with the main position of Langshan as the core, and more than 100 permanent firepower points. Each support point has a telephone as a means of communication and communication.

Two hundred and twenty light and heavy artillery are deployed in twenty large permanent artillery shooting fortifications. These large underground fortifications are completely new to this era, and their designs can be called the highest. The main fortifications of Langshan are built at a depth of twenty meters below the mountain top or ridge. They are surrounded by long main tunnels made of stone and reinforced concrete. One end of the main tunnel is connected to a simple living area. The other end is a combat area. These areas can be reached through smaller tunnels, steps and lifts. The largest large underground fortification support point is equipped with a battalion troops to guard them. Through these tunnels, people are transported by rail vehicles.

Equipment and ammunition.

Independent large underground fortifications rely entirely on electricity to provide energy and are equipped with all the facilities required for life. Each large underground fortification is a self-sufficient underground town with its own wells, food supply and power generation equipment and oil reserves. It can be isolated from the world and survive independently for up to two months. It is very likely to threaten the Japanese army's toxic gas attack, and ventilation and filtration equipment with slightly higher pressures are generated in the fortifications.

The howitzer group does not directly observe the target during combat. Ground observers use telephone to notify the underground fire control command post to command and correct the artillery fire. The core command post of Zhonglong in Langshan will convey orders to each bunker, which is equipped with cannons, dibasins and machine guns.

The core fortification bunker Zhonglai prepared dozens of heavy machine guns, and carried out shooting without dead angles. The 100-mm cannon is hidden in a steel-made turret, and the turret is fixed on a circular rotary table made of steel and cement. Since only one steel dome is exposed on the ground, it is impossible to find it from a distance. Therefore, the cannon appears very safe in the war room, in order to consider

If Japanese soldiers infiltrate and pass through the machine gun fire to the exterior wall of the fortification, hand-controlled grenade launchers like chute oil cylinders can send batches of grenades out of the wall to destroy the enemy. If an enemy attacks the gate and enters the underground fortification passage, they will be shot dead by a bunker machine gun inside this large underground fortification.

The main fortification Zhang Xuewu's requirement is to be able to withstand the direct hit of a 240 mm heavy artillery. Behind one meter of concrete is a neatly arranged boulder, steel plate and half a meter of concrete poured.

Zhang Xuewu mainly considered the powerful fortification killer of the Japanese Army's Type 38 150 mm cannon, especially after the Japanese failed to siege four fortress cities last time, the Japanese developed a new Type 97 150 mm cannon. It can be said that war is a catalyst for military industry. The reason why the Japanese did not manufacture Type 97 150 mm cannon in history was that it was of no use to the Chinese army, which even the 75 mm caliber was called heavy artillery. The reason why they did not create a large number of tanks was because of the limited resources, and the other was that it was used on the Chinese battlefield, which required development.

Now the Japanese discovered the importance of tanks, but it is definitely too late to design and produce them now, so the Japanese used their ultimate imagination and invented various ways to fight tanks with Japanese Yamato ethnic characteristics.

It can be said that the overall construction of Chaoyang Loushe City is more than the total investment in Chengde, Chifeng and Zhangjiakou, because the yellow houses mined from Chaoyang are continuously transformed into various equipment, equipment and industrial products that Zhang Xuewu urgently needs through Zhou Ying.

The Japanese attack came very suddenly, and even unexpectedly. The 13th settlement was interrupted for a day, and the rescue convoy sent was not heard from. Although Dai Peng was the commander of the security commander, due to Chaoyang's special nature, he was basically a chore of placing horses to control the army and dismounting horses to control the people. If there were large-scale casualties, he would be blamed. Dai Peng had never thought about the tank company of Lu Yu, stationed near the East Gate. It was the weakness of Chaoyang Fortress. It was like a powerful master who had a life gate. The seemingly the life gate of the powerful Chaoyang Fortress was at the East Gate. It was not the only way to contact the outside world during the Chaoyang war... However, in front of the Daling River with sufficient water, all forced ferry could only become a cloud.

But now the Daling River is frozen! This is also the most important reason why Dai Peng is upset. One of his garrison divisions is scattered at various support points in the fortress. His only mobile force is only one battalion and his division-owned guard company. Not to mention counterattacking, this force is insufficient even if the patrol and alert Chengdu is insufficient. However, Dai Peng also believes that the Japanese will not take the risk of launching an attack in such a cold world, and the Japanese's equipment does not seem to be enough to cope with the sudden cold.

However, soon bad news came. The convoy he sent was sent with only one car. Two wounded soldiers fled back. They claimed to have encountered a large Japanese army, but they could not explain the size and number of the Japanese army. Obviously, their troops were caused by an organized ambush by the Japanese army. What made Dai Peng confused was what he should do? Is it just a Kwantung army unit that took risks? Or was the Japanese army intending to launch an attack on the entire Chaoyang Fortress? At this time, launching an attack on Chaoyang?
