Dai Peng circled around the trailer a few times, and by his feeling that this must be a guy much larger than the Jackal light tank, especially the long barrel, which clearly shows that it is a tank, and the casual battlefield repair vehicle and ammunition truck also explain the problem.

The person in charge of the convoy was a young captain, and after questioning Dai Peng, he learned that the captain's name was Lu Yu, who belonged to the special armored unit directly under the theater of operations, and they were a passing experimental unit.

In fact, Lu Yu's test team is responsible for transporting a high-intensity marching operation in the mountains and testing the new load-bearing wheel test escort detachment, six jackal-type light tanks in the company, plus a command vehicle, three accompanying ammunition vehicles and two full-featured terrain vehicles, the so-called full-featured terrain vehicle is a large armored vehicle, which can be used by eight people to live, but the two large full-featured terrain vehicles escorted by Lu Yu have three male engineers in one car and two female load design and scientific research personnel in one car. Living in the car is much warmer than living in the house in the barracks, and the bathroom is complete, Lu Yu is naturally envious of the treatment of scientific researchers, but science and technology is the first combat effectiveness, as long as the iron horse completes various improvements and tests as soon as possible, that is the happiest thing for Lu Yu, although the Jackal light tank can be outstanding, but to put it bluntly, it is still a light tank!

In the minds of true armorers, the torrent of steel refers to medium and heavy tanks, and the torrent of steel will crush any enemy who dares to provoke.

However, heavy snowstorms and difficult roads hindered Lu Yu's retreat plan, the first garrison division is the only one in the garrison that has strengthened a well-prepared brigade, and the rest of the divisions are all two brigades and four regiments, even so, the second heavy fortress artillery group of the Chaoyang garrison and the defenders are all added up to more than 19,000 people, which can be described as a weak force, and now all personnel have participated in the snow removal operation in Chaoyang City.

In the eyes of the poet, the snow may be beautiful, but in the eyes of the common people, the heavy snow means disaster, the livestock are frozen to death, the houses are crushed by the heavy snow, the residents in the more than 20 settlements near Chaoyang are now gathering in Chaoyang City, Dai Peng, as the commander of the garrison, also prepared a large amount of food and resettlement sites.

Chaoyang is a historical and geographical city, since the Western Han Dynasty has set up counties, Chaoyang was called the place of Liaoxi outside the ancient times, because the geographical location is in the Central Plains to the northeast of the ancient traffic points, the historical ethnic activities are in the Central Plains Han and the Northeast ethnic minorities exchange and integration of the link area, so the Central Plains dynasties have set up border towns here, and the Northeast ethnic groups into the Central Plains should also take this place as a place to fight, so that Chaoyang has become a strategic place outside the Central Plains.

The surface layer of Chaoyang is mountainous, the hills are undulating, the canyons are intertwined, the ravines are vertical and horizontal, there are only small pieces of flat land between the mountains and the impact plains along the river, and the structure is a typical area of seven mountains, one water and two fields.

However, Chaoyang is rich in mineral resources, especially mineral resources, which have the characteristics of wide distribution, many types and great development potential. At present, more than 50 kinds of beneficial mineral deposits have been found in the territory, more than 500 production areas, the proven reserves of manganese reserve rank first in Northeast China, the output of molybdenum ranks second in the country, and it is one of the eight major gold producing areas in the country.

Therefore, when Zhang Xuewu had a counteroffensive in Chengde, he first ignored the actual situation at the time, and resolutely drove the remnants to forcibly fight Chaoyang, and then immediately began to build Chaoyang Fortress.

In addition, since the end of the Rehe Battle in 1933, the national defense fortifications personally led by Zhang Xuewu of Chaoyang have not stopped, and have been built on the basis of a large number of manpower and material resources, including during the siege of the army, Chaoyang's fortifications have not relaxed at all.

The overall layout of the Chaoyang fortress city is along the Daling River in the urban area using the original city wall to pile up earth and stone, to create a five-kilometer-long, 30-meter-wide defensive isolation zone, the use of bluestone accumulation, concrete pouring method, digging underground bunkers and passages below, with the main position of Wolf Mountain as the core, more than 100 permanent firepower points, each support point has a telephone as a means of communication.

Two hundred and twenty light and heavy guns were deployed in twenty large permanent artillery firing fortifications, which were completely new for this era, and their design could be called revolutionary, the main fortifications of Wolf Mountain were built at a depth of twenty meters at the top of the mountain or ridge, and were surrounded by long main tunnels made of stone and reinforced concrete, one end of which was connected to the simple living quarters, and the other end was the combat area, which could be reached by smaller tunnels, stairs and elevators. One of the largest large underground fortifications was garrisoned by a battalion of troops, through which men, equipment, and ammunition were transported by railcars.

Each large underground fortification is a self-sufficient small underground town, with its own wells, food supply and power generation equipment, and oil reserves, which can be isolated from the world, and can survive for up to two months, and for the threat of poison gas attacks that are very likely to be carried out by the army, there is a slightly higher pressure ventilation and filtration equipment in the fortifications.

The howitzer group does not directly observe the target during the operation, the ground observer notifies the underground fire control command post by telephone to make command corrections to the artillery fire, and the central core command post in Wolf Mountain will convey orders to each bunker, and the large bunker is equipped with cannons, mortars and machine guns.

The bunker of the core fortification is equipped with up to dozens of heavy machine guns, which fire without dead angles, and the 100-millimeter cannon is hidden in a steel, liftable turret, and the turret is fixed on a circular turntable made of reinforced concrete, because only a steel dome is exposed on the ground, which cannot be detected from a distance, so the cannon appears very safe in the war room, in order to take into account that if there is a soldier infiltrating through the machine gun fire to reach the outer wall of the fortification, Hand-controlled grenade launchers, like chute cartridges, can send batches of grenades out of walls to destroy enemies, and if an enemy breaks through the gate and enters the underground fortification, they will be shot by a bunker machine gun inside the large underground fortification.

The requirements of Zhang Xuewu, the main fortification, were to be able to withstand the direct hit of the 240-millimeter heavy artillery, and behind the one-meter-thick concrete were two meter-thick neatly arranged boulders, steel plates and half-meter-thick concrete poured.

Zhang Xuewu mainly took into account the powerful fortification killer of the 38-type 150-millimeter cannon of the Yue Army, especially after the failure of the 38-type 150-mm cannon of the 38-type army, especially after the failure of the last comprehensive siege of the four fortress cities, he said that he developed a brand-new 97-type 150-mm cannon, it can be said that the war is the catalyst of the military industry, and the reason why he did not make the 97-type 150-mm cannon in history is that the [***] team, which is called heavy artillery with a caliber of 75 mm, is of no great use at all. One of the reasons for not manufacturing a large number of tanks is the limitation of resources, and the other is that it is a waste to use them on the Chinese battlefield, and the need to promote development.

Now I have discovered the important surname of the tank, but it is definitely too late to design and produce, so I have used my ultimate imagination to invent a variety of ways to fight tanks with the characteristics of the Yamato nation.

It can be said that the overall construction of the fortress city of Chaoyang is more than the total investment of Chengde, Chifeng, and Zhangjiakou, because the gold mined from Chaoyang is continuously turned into various equipment, equipment and industrial products urgently needed by Zhang Xuewu through Zhou Ying.

Although Dai Peng is the commander of the garrison, but due to Chaoyang's special surname, his garrison commander is basically on the horse to manage the army, and he is also to blame for the large-scale casualties, for the tank company of Lu Yu stationed near the east gate, Dai Peng did not think about anything, There is the weakness of the Chaoyang Fortress, just like the powerful masters have a life, the seemingly powerful Chaoyang Fortress's lifeline is at the east gate, where is the only way to communicate with the outside world during the Chaoyang War, but in front of the Daling River with sufficient water, all the forcible crossings can only become floating clouds.

But now the Daling River is frozen! This is also the most important reason why Dai Peng is upset, one of his garrison divisions are scattered in various support points of the fortress, and his only mobile force is only a battalion and his divisional guard company, not to mention counterattack, even the patrol cordon is insufficient, but Dai Peng also believes in the judgment of the theater staff, he will not risk launching an attack on such a cold day, and his equipment does not seem to be enough to cope with this sudden cold.

However, soon the bad news came, the convoy he sent only one car and two wounded soldiers escaped, they claimed to have encountered a large army of the army, but they did not know the size and number of the army, obviously their troops were caused by an organized ambush by the army, what confused Dai Peng was how to deal with it? Just a risky Kwantung Army unit? Or did the army intend to launch an attack on the entire Chaoyang Fortress? Attack the rising sun at this time?

Dai Peng felt that it was really a little unimaginable, but Dai Peng still organized the officers and soldiers to immediately stop the cold relief work, and began to clear the snow on the defense line, the frozen fortification firing ports, and the rotation mechanism of the rotating turret.
