Although the German army did not prepare for permanent fortifications, the positions were still carefully constructed. Compared with 20 years ago, their trenching skills have not dropped at all. There are countless retired men in the national defense force who are good at trenching. They learn and use the trenches they have seen all their lives, and they look down on the blitzkrieg of the national defense force. Almost every time these people hold a meeting, they will attack the tactics of Blitzkrieg that the head of state is the most precious. They have assumed countless times how they would arrange their own defense lines if they were given enough time to make a mess of the Blitzkrieg. When the head of state threw out the theory of defense in depth in the east line, these people firmly stood by the side of the head of state akado, and did not mean to hold the head of state to the altar of tactical masters. Therefore, the position where the German army is hiding now can be said to be "the strongest defense system in the non permanent fortifications", which is the original words of an infantry general in his report. Since it can be praised by the most authoritative antiques of trench warfare, these lines of defense are not as simple as some shallow pits. All defensive positions are required to be M-shaped rather than a simple straight line. On both sides of these M-shaped trenches, there are shallow pits and traffic trenches for transferring troops. Behind these trenches, there are T-shaped anti explosion relief pits. As long as the cannonball does not hit the multi-point joint of these tunnels, a little deviation will reduce the power of these cannonballs by more than 70%. If it deviates a few meters, then even the large caliber heavy artillery cannonball will not cause fatal damage to these simple trenches. After the key parts were reinforced with wood and cement, several defensive points of this defense line had the ability to resist the artillery coverage. If we take into account the 20 km elastic defense area preset in the front of the whole main defense line by the defense in depth theory, this defense line is enough to deal with any attack means of the Soviet Union. Of course, akado is not a God, but he stands on the shoulders of giants at least. The military experts of the former Soviet Union dug a big hole for the German armored forces in Kursk for half a century. Now he took it and used it on the Red Army of the Soviet Union. It seems that he suddenly felt the pleasure of doing something for another. The German veteran fell down in a fork of the T-shaped anti explosion tunnel. At about the same time, a shell also landed in another corner of the tunnel. The explosion suddenly raised countless soil and buried the soldiers who were hiding in other corners. After a long time of explosion, the German veteran got out of the soft soil and shook off the gravel and black mud hanging on his helmet. His ears were buzzing because of the huge noise. Although he covered his ears in time, it would take him at least a few minutes to recover. This is his experience after being shelled by the French. He shook his head for a while, then picked up his gun from the floating soil, then turned back to his trench and saw several comrades who had just come back. These soldiers have long been told to listen to the advice of the veterans as much as possible. Although they are afraid, they have been training for three months in the eastern line with the trench they dug. It is their instinct to listen to the Veterans' reminders and avoid the shells that may hit them. So just now, they all fell to the ground without hesitation, Avoiding the huge shock wave and countless shrapnel of Soviet shells. If the Soviet artillery saw this result, it might be crazy, because a German shell on the attacking Soviet position could basically take more than a dozen or even dozens of lives. However, although the shells they fired were more powerful, they could only occasionally add a few wounded soldiers to the German army.
