Either "your ass is pouting too high, deliberately remind the enemy that the machine gun will kill you, Lao Tzu will kill you first", "You are throwing grenades, not rotten eggs, do you want to kill everyone, Lao Tzu will kill you", and then they were violently beaten by the instructors.

The most cruel thing is the white-bladed training, although the wooden stick is wrapped in cotton, the returnees are still beaten by the instructor and are covered in injuries, all of them are blue and purple, crying dad and calling mother in pain when taking medicine, ghosts crying wolves, Qin Guodong is still talking cool next to him, this is for your good.

This guy also thought that the students were not honest, and said that the devil's bayonet was 1.7 meters long, and many old devil soldiers could take out their hearts completely after stabbing and pulling, and the stabbing was so bloody and cruel that the students were scared away, so they had to ask Instructor Wen Biqing for advice.

Instructor Wen didn't have a good way, so he suggested that everyone go to buy Remington in the United States, and as soon as the bullets go down, you can refresh a large piece, and you can also have an extra pistol to shoot left and right, plus his exclusive invention of a one-handed magazine, which can continue to fire so that the enemy can't get close.

Liu Yun and the returnees all understood, it was best not to fight with the devil in a white-knuckle battle, what could be solved with bullets, and resolutely solved with bullets, "bayonets are cowards, bullets are warriors", and later these returnees can be equipped with two pistols wherever they go, and they are definitely not worthy of one.

After the outward bound training, in order to open the eyes of the returnees, the principal Yang Gengguang led the team to teach the corps to visit the senior brothers of the regular class, and by the way, take a look at the machine guns and cannons in service, such as 150mm heavy artillery, 120mm field artillery, 105mm field artillery, 75mm mountain artillery and G34 general machine gun.

The truth is very cruel, in addition to the G34, it is a bit interesting, the other heavy artillery and field artillery are scum, most of them are the products of the Beiyang era, the youngest are older than Liu Yun, fortunately, the brain is not picky, and all the brains have been copied, but the situation of the armored forces is even more stunning.

Liu Yun stared wide-eyed and looked for a long time, but he didn't see a tank, the most common is the "Renault" FT-17, or the car with steel plates, the most bizarre is the American tank, directly on the agricultural tractor, welded a few steel plates, may be the weakest tank in the Republic of China.

Anyway, the returnees have little knowledge, a bunch of steel monsters, when they roar out, they feel terrible when they see it, and finally visit the aviation unit and the air defense force, which is the Nanjing National Government, the only high-tech force that can handle it, and the fighter plane is the main force of the American Hawker II.

There are also some old biplanes that have been used as transport planes and reconnaissance planes, but Liu Yun's optimistic Hawker III has only a pitiful three, and the remaining dozens of planes that have been ordered will not arrive in Nanjing until after the "Far East Arms Sales Quota Conference," and can only be used as training planes at present.

The anti-aircraft weapons are complete, 37mm, 47mm and 88mm anti-aircraft guns are available, but the Maxim machine gun and the G34 twin machine gun are the main force of anti-aircraft weapons, and there are only a few powerful 88mm anti-aircraft guns, and it is said that the unit price is comparable to the German 150mm heavy gun.

On the second day after returning from the visit, when he was preparing to learn military theory with the instructors, a major incident happened at Lu University, it is rumored that President Yang discovered corruption in the Air Force when he inspected the Air Force, and was about to go to Lushan to sue the Emperor Yunyun.

The theoretical study lasted for a total of 12 days, divided into tactics and command, the history of revolutionary warfare, the history of foreign military warfare, and politics and economics, four major subjects, and there were two classes in the morning and afternoon every day.

"Tactics and Command", by the German Spemmann, this person is a veteran of the First World War, who still can't speak Chinese dialect well in China for many years, so he has to be interpreted by a translator.

Liu Yun was furious, relying on the synchronous translation of the intelligent brain, Mao Sui recommended himself to serve as the translator himself, and after the verification of Instructor Spemmann, he agreed to try it out first.

Speemann's speech is very simple, based on the German version of "Army Command", summing up the lessons learned during the First World War, because the translation of Zhinao is more accurate, and the returnees are more relaxed to listen to, Liu Yun feels that what the Germans said is very useful, so he wants to get first-hand information.

Starting with the battle formations at the group, squad, and platoon levels, Speman focused on how to make use of different terrains, how to arrange light and heavy firepower, how to attack and defend, how to make roundabouts and counter-detours, how to pay attention to subtle changes in the situation between the enemy and us, and how to master fleeting fighters, and so on.

After that, it gradually transitioned to battalion, regiment, and brigade level tactics, all the way to the division, army, group army level, and even the large-scale tactics of the front army and cluster army.

The German instructor repeatedly stressed that in war, it is necessary to pay attention to the change of strategic and tactical situation, to the influence of the terrain, and to the relationship with changes in time and space, such as the "far, near, dangerous, easy, wide, and narrow" of the enemy and the enemy.

This concentration is not a simple concentration, but a combined concentration of multiple technical arms, such as the three-dimensional attack and defense of the sea, land, and air arms; once a war breaks out, it is necessary to quickly seize air supremacy, use the technical arms as the vanguard, and quickly break through the enemy's defense line, so as to achieve a quick victory.

"History of Revolutionary Wars", headed by President Yang Gengguang, takes the history of the Northern Expedition (1924-1928) as an example, interspersed with the history of the Napoleonic War and the history of the Russo-Japanese War, and the history of war is the mother of tactics.

The GUO Kuomintang also actually talked about "revolution", Liu Yun was simply refreshing, before seeing a subject of "revolutionary war history", I thought it was dazzling, only then did I know that the GUO Kuomintang also regarded itself as a revolutionary party, the army is called the "National Revolutionary Army", and the history is called "revolutionary history".

The "History of Foreign Military Wars", which was supposed to be held by the German Gushi, was temporarily called away by the general adviser Hans von Seckert, and was replaced by the local instructor Gong Hao.

This course focuses on "precise logistics supply" and explains the promotion of new weapons, such as dreadnoughts and aircraft tanks, the development of new arms, such as chemical troops, communications troops, and engineers, as well as the fusion of new ideas, such as trench warfare, general warfare, multi-arm composite warfare, and so on.

"Politics and Economy" was held by Ma Yinchu, a population expert, who started from the traditional economy, analyzed the current political pattern in China, and finally crooked to Sun Yat-sen's "Three People's Principles", and finally emphasized that "only by overthrowing imperialism and feudalism can the Three People's Principles society be realized".

At the end of the theoretical study, President Yang and German instructor Shi Peiman jointly assigned a comprehensive assessment assignment, "On Nanjing's Territorial Defense, Taking the Maginot Line of France as an Example", which must integrate four theoretical subjects, and the score will account for 40% of the final assessment.

After the theoretical study, it was a three-day field training, which happened to be trained with the trainees of the 10th regular period, because they were about to graduate in three months, and the area of the exercise was in the three major mountainous areas around Nanjing, namely Fangshan, Zhongshan and Niushou Mountain.

Led by five or six instructors such as Qin Guodong and Wen Biqing, with 105 returnees to engage in training, at the beginning, some students were still overwhelmed, and wanted to say goodbye to the senior brothers in the regular class.

At this time, I knew how gentle the instructors were to them, and the returnees were ashamed, and their morale suddenly fell to the freezing point, but fortunately, the instructors had already prepared and directly explained the reason, "How many years have they practiced, how many days have you had, if you can practice for a few more years, you are not worse than them."

Knowing that it was fake, everyone still regained their confidence, Ah Q's spirit flashed again, and the returnees were resurrected on the spot again, happily continuing their field training.

Field training is to train returnees to survive in the wild, march in the field, communicate in the field, and deal with emergencies, etc., the instructors have passed on their own teachings, selected 3 top soldiers in each column, formed 5 groups of scouts, and searched for one kilometer to the southeast, northwest, and northwest.

Regardless of whether there is a situation or not, the flag must be sent back every ten minutes to show the safety of the surroundings, and another group must be selected from among them, and then a squad will be joined to form an advance team of 10 people, which will be specially responsible for finding water sources, detecting the location of possible emergencies, and doing preliminary work for the passage of large troops.

That night in the Niushou Mountain camp, the instructor explained how to camp on the spot, in order to prevent wild beasts and possible enemy attacks, etc., everyone was a little exhausted, fell asleep, in the middle of the night the instructor excused someone to attack at night, blowing the emergency assembly whistle, everyone could not figure out the true and false, and a burst of panic, and when it settled down, the sky was almost dawn, and had to continue to set off in a hazy sleep.

In the next two days, the instructor also repeatedly created a terrifying atmosphere, warning that he might be ambushed, everyone has been nervous, and also found several suspicious places, it turns out that they are all scared of themselves, until everyone thought that they were okay, and they were dumplings by the senior brothers.

When I returned to the guest house, it was only a few days before the end of the military training, and it was specially left for the returnees to write a thesis, or to welcome the review of Lao Chiang, etc., the thesis was Liu Yun's specialty, just with the prediction and assumption of the war, to explain the situation of the Battle of Songhu, the paper has seven chapters.

First, it is necessary to demonstrate the triangular relationship between Shanghai, Hangzhou, and Nanjing, analyze the strategic value of each other's district committees, and believe that the defense of Nanjing should not be considered alone, but should also be considered as a regional integration, otherwise once Shanghai and Hangzhou fall, Nanjing will have no danger to defend.

Second, analyze the potential threats of the Grand Triangle and the future challenges of the Maginot Line.

Third, analyze the threat posed by the new weapons to the two and the differences in specific defensive measures.

Fourth, the Shanghai-Wusongkou frontal defense, and the Franco-Dutch elastic defense.

Fifth, the defensive blind spots of the two are discussed, and the landing of Hangzhou Bay and the crossing of the Ardennes Forest are analyzed.

Sixth, after the enemy occupied Songhu, the troops were divided into three routes to encircle Nanjing, and the part of the landing in Hangzhou Bay made a detour to Wuhu to cut off the retreat of the defenders, resulting in the fall of Nanjing. and the main force of the enemy after crossing the Ardennes Forest, cutting off the Maginot Line from the outside and encircling the main French army, leading to the surrender of France.

Seventh, new tactics and prospects, analysis of blitzkrieg and pincer offensive.

Appendix, General Ideas for Heavy Tanks, Medium Tanks, Self-Propelled Artillery and Armored Vehicles, and Mechanized Vehicles, with various design sketches.

After the paper was written, Liu Yun also translated it into German and handed it to Yang Gengguang and Spemmann respectively, hoping to minimize the losses in the Battle of Songhu and contribute to Germany's future conquest.
