The German Führer began to prepare and successfully build various military academies for the German war as early as 1923. If one analyzes this period of the black history of the Wehrmacht according to the experience of a normal person, one will certainly be deeply impressed by the foresight of Führer Accardo Rudolph.

The German Panzer Corps Command Academy is the highest non-commissioned officer training academy offered by the Army. Numerous commanding elites of the German armored forces graduated there. And there was once ordered to train demons who kill people without blinking, although the training program called Wolf Knight was eventually terminated for various reasons, it cannot be denied that the German armored forces still became the most combat-ready unit in the world through these training and exploration.

The Air Force learned to fly outside the frigid outskirts of Moscow, where they practiced strange tactics in droves using outdated aircraft, each time being ridiculed by their Soviet counterparts. They insisted on using all kinds of shoddy tactics, stubbornly using old planes to climb and dive to attack their targets, and they were completely wiped out by Soviet pilots at every test.

Still, the pilots persevered in their training and brought back to Germany the methods of air combat that were certain to die. They train more trainees at the glider school, who also clumsily fly gliders to learn to dive and pull up.

This Qiē was no longer the same after the Me-109 and FW-190D fighters entered service, and the German pilots finally understood why they were being asked to learn the method of air combat that was sure to die, because this dance of death could indeed make their opponents certain death.

The academy formed by the Navy is a hodgepodge of training all kinds of new gadgets. Carrier-based pilots practice taking off and landing on a runway of fixed length and width all day long, and are familiar with that runway to an incredible distance. Some pilots even closed their eyes and landed on the ground to prove that they were fully capable of any take-off and landing difficulty.

The training classes that were secretly assembled were so strange that it was impossible to distinguish the real from the fake. The Navy's radar unit is even testing a new radar small enough to be mounted on a destroyer and capable of detecting enemy targets up to 35 kilometers away.

However, after entering the Navy's submarine non-commissioned officer training school, everyone will say that it is nothing more than the various schools above. All the students who can come to this school are the elite after completing the basic training of the Navy with excellent results. This is where they undergo more rigorous special training.

Here they learn joint operations, special skills, and how to survive in the face of strong enemies. These are all essential to save yourself in the future against the enemy. The instructor looks for and discovers these qualities in the students, and then carefully cultivates and reinforces them - those who do not meet the standards, about 90% of the trainees, are eliminated, are dismissed, and return to the navy to continue their service.

In the first phase of the school's training, all recruits spend 12 hours a day focusing on physical training and general knowledge of the internal operation of submarines.

These students had to look intently at the multimeter as they took a basic course on using the electric motors on their submarines at the submarine school. They connect one end of the wire to the battery and the other end to the multimeter, and when the wire is closed and closed, the current flows from the battery to the meter, and the pointer shows how strong or weak the current is. When the battery in the submarine is depleted, the current decreases, and the indicator pointer approaches the 0 position. By interpreting this change, these submarine operators can determine when their vital batteries must be recharged.

For submarine commanders, how to judge the distance and bow angle of an enemy ship on a submarine with poor visibility, and how to quickly determine whether the ship is moving forward or backward are very important skills, and there are special equipment in this school to train them.

In the dedicated classroom, the course practice is very close to the actual combat. The officers were ordered to stand on a raised platform arranged as a submarine conning tower and observe the target with the telescopes above. These telescopes are specially made of high-performance binoculars, exactly like the telescopes they used in actual combat.

The target is a model of a ship that can change any driving parameters with someone in the background. Backstage operators wear intercoms and headsets, and examiners randomly set the parameters of the model boat, and the submarine commanders are asked to use binoculars to estimate angles and judge the distance of enemy ships based on how much hull can be seen on the horizon

In fact, these are far from the most annoying projects for these students. The computing course here also has boring math jù summaries, which are the most boring subjects. The teacher talks about it and then notes it down on the blackboard with chalk. This knowledge is related to oil pressure calculations, nozzle pressure, the flow rate of the liquid in the pipe, and related numbers such as fuel injection and temperature. At sea, the officers and men of the submarine had to record these numbers every day on the relevant texts. It's boring and boring, but it's one of the most important jobs.

In a one-to-one, full-scale simulation environment, the trainees were asked to connect the operation of the control panel and the control of more than 210 valve switches on the submarine. It also simulates the noisy working environment inside the submarine and the sweltering temperature inside the submarine.

Accardo personally visited the classroom and asked Dönitz, who had accompanied him, with great curiosity: "General, how can we be sure that the trainees have mastered these complex operations after the training?"

"It's simple. My Führer. Dönitz walked to the end of the narrow hallway, then reached out and turned off the light switch on the wall, and the whole room was dark: "If you can find and operate all the switches and panels, you will graduate." ”

"If I come to learn this, I'll be eliminated on the third day. This was the Führer's comment to Dönitz before he left the school. Dönitz's answer pleased the Führer: "These cadets are willing to die for you, my Führer! ”

Another novel training course is the diving training, in which the trainees have to practice and learn to breathe underwater with an artificial lung, in a special tank. This device is far less advanced than today's oxygen cylinders or artificial lungs, but a vest device. In order to obtain oxygen from the oxygen cylinder stored in the zài vest, the trainee must quickly open and close the side valves, the outlet on the brass drum mask for inhalation and exhalation. There is also an emergency valve on the vest that emits carbon dioxide, which is located in a more comfortable position on the chest.

Before the diving course, the instructor repeatedly demonstrates to the students how to use the underwater equipment and how to properly wear the breathing mask. The students will then be accompanied by their teachers to put on artificial lung vests and wear heavy lead shoes and sink to the bottom of a 21-foot-deep glass box.

Here they will practice how to open and close the conning tower hatches, the sealed doors in the cabins, and repair various valves and housings underwater – more complex than astronauts like the astronauts do today to repair their shuttles.

Of course, while learning these things, they are exposed to many other things. For example, they will learn shooting and aiming techniques, navigational knowledge, how to distinguish charts and routes, torpedo ignition and weapon principles, and learn how to operate radios, diesel engines, electric motors, and air compressors. Of course, one of the most important training is how to quickly open and close the hatch in an emergency.

In the second phase, these soldiers undergo specialized training, which is generally not completed in school, but in the submarine force. They are assigned to submarine units as observers on duty and as trainee non-commissioned officers, boarding submarines on patrol missions or participating in exercises.

Then they will go back to school again to make final preparations for boarding their own submarine. At this time, they had to challenge themselves in every position, as torpedo mechanics, engineers, and radio operators, until they were able to perform almost every job on the submarine.

The new commander and his crew will be given a short vacation after graduation, which is not free, of course, and they will be sent to the submarine factory in Kiel, where they will watch their warships being built. Nurture their feelings for their own submarine equipment.

When the submarine is completed, it will become their exclusive weapon. Over the next two months, they will complete various tactical studies on this warship, which will be explained by the supreme commander of the submarine, Dönitz, to deepen their understanding of the performance of the submarine and the tactics of the wolf pack.

The submarine will then go to sea and join the wolves to begin its combat career, simulating various combat situations in the calm waters of the Baltic Sea, dealing with various faults, including stuck steering wheels, compressed air leaks, ruptured pump valves, water leaks, and damage to the hull.

"For a moment, you feel like you might be the most perfect fighter in the world, you can do almost anything, you feel like you can accomplish any task, and you are not afraid of all enemies...... "One submarine commander wrote in his diary.

However, he corrected his opinion a few days later, and when his submarine was ordered to carry out a mission in the rough North Atlantic, he realized that he had been wrong. He wrote in his diary: "The other day I felt like I could do almost anything, but these days I have been completely dazzled by the real combat environment - the wind and waves here are five times greater than the Baltic Sea, we have to fight with loneliness and boredom, there is oil everywhere and the smell of sweat, and I have to work naked inside minus ten degrees outside, this place is no different from hell." ”
