In other words, in the middle and late stages of the Second World War, that is, after 1943. Nazi Germany's strategic delusions of wanting to conquer the whole world, with one failure after another, eventually made their beautiful fantasies come to naught.
The Nazi Fuehrer, who once believed that Lao Tzu was invincible, had to reconsider how to rebuild the defensive facilities in the face of increasingly difficult ambitions to achieve and the relentless blows of reality, in order to consolidate the gains won in the early stages of World War II.
However, in 1942, the Germans had already invested a lot of manpower, material and financial resources to build the "Atlantic Wall", a project that consumed a lot of strategic resources, and Germany was already stretched to the limit, and could no longer afford to build more large-scale defensive projects.
It was in this environment that an organization in Nazi Germany called "Tot" (an organization contracting various projects) made a proposal to the top: by dismantling the old tank turrets and then building bunkers on the foundation, the tank turrets and the bunkers were combined to form a defensive front. This is the so-called protective structure bunker construction concept.
In this way, not only can the previous "waste" be reused to build a solid defense, but also a lot of manpower, material and financial resources can be saved.
As soon as this idea was proposed, it aroused great interest from the Top Nazis, and the order was soon carried out immediately. This "project" is listed as a key project, and the progress of its implementation must be reported to the high level on a regular basis. Under the great attention of the Nazi high command, the project was carried out very efficiently.
The project was named " Order No. 3 on Construction Work " , which included the construction requirements for the conversion of various old tank turrets into bunker guns , as well as various detailed design drawings.
The Germans are very strict in their work, and the construction orders are issued from above, and the people below will spare no effort to do a good job. In order to improve the efficiency of engineering and construction, the Germans began to decide to use standard German construction methods, and at the same time, they also uniformly numbered bunkers of the same category.
Moreover, on these numbers, they gave the bunkers a uniform name: Regelbau, which translates to Chinese: "standard design.".
For example, the Regelbau-238, which means a defensive turret-type bunker constructed from the turret of the Panzer II, while the Regalbau-638 represents a small turret-type bunker that can be used to defend field hospitals.
Among these standard designs, the most famous is the turret bunker built from the turret of the "Leopard" tank, which the Germans gave him the nickname "Leopard Tower". Its number is: Regelbau-687.
The reason why this "leopard tower" is so famous is because in April 1944, the Germans built a defensive line in the northern Gothic region of Italy, and they built many "leopard towers" on various traffic passes by virtue of the steep terrain.
Relying on these bunkers alone caused great trouble for Britain and the United States, becoming a huge "stumbling block" in their way forward, which really caused headaches for the Allies.
The great success of the "leopard tower" built by the Germans in Italy led to their continuous promotion at the end of World War II, but even if the Germans designed the fortresses well, it would not save them.
Until the end of World War II, many "leopard towers" were only half built, and they were conquered by the armies of the Allied camp, leaving only many semi-finished products and some war wreckage.
