The departure of Sun Qian and the others can be said to be uneventful, just as if they did not exist before, only occasionally they will be talked about by chatting soldiers, and the rest is nothing. As for Sun Qian's bitterness being drunk by Chinese medicine, it has nothing to do with them.

Sun Qian, who returned to Paris, did not have the heart to hang out again, and most of the time they spent in the hotel except for necessary physical exercise. The hotel was given by Every in advance, and they had to summarize all the experiences of this time and use words to form a standard tactical guidance model. Sun Qian even unashamedly named this summary "Sun's Drill Code", which made Sun Xing laugh for several days.

To tell the truth, this drill is more of a summary of assault tactics, and does not have much guiding significance for real infantry operations, and is even more contrary to the operations of large corps, and can only be regarded as a supplementary form of infantry operations. Therefore, Sun Gan's summary is more of a summary of his previous assault operations.

Of course, Sun Gan's summary is still very meaningful to a certain extent, when the two sides are in a tactical stalemate, the use of the commando form is very likely to break the stalemate between the two sides and obtain tactical and strategic advantages, so Sun Gan's research is also very valuable.

It can be said that Sun Qian's current summary is still dispensable in the eyes of everyone, but when it is really implemented, people gradually recognize the value of the "Sun Drill Code", and Sun Qian and the others are also considered to be the originators of modern special operations.

Of course, the two who want to be "salted fish" do not really want to be "salted fish", they will still go out and go around, this day the two asked people along the way about "Chinatown", this is a gathering area for Chinese, where a large number of Chinese laborers gather, looking at the familiar yellow skin, Sun Qian and the two once again feel at home.

Sun Qian knew that the attitude of the Beiyang government towards the great powers was not to be offended by anyone, so he did not directly participate in the war, but he was afraid of facing the reproach of Britain and France and other powers, so he finally remembered to participate in the European war in the name of "labor export", so these laborers were not considered soldiers.

According to later statistics, from August 1916 to November 1918, China sent more than 140,000 laborers to Europe, and Russia also recruited about 50,000 Chinese laborers. These Chinese workers are mainly from the north (especially from Shandong), but also from Hubei, Jiangsu, Hunan, Anhui, Shanghai and even Hong Kong. And after the Beiyang government declared war on Germany, almost all Chinese laborers were sent to the front. From digging trenches to repairing fortifications, from field rescue to exhuming corpses, from building roads and bridges to transporting grain, grass and ammunition, Chinese workers are engaged in the most arduous and arduous work. After the end of World War I in 1918, Chinese laborers who had experienced two years of war did not immediately return to their homeland, for example, there were about 96,000 Chinese laborers under British supervision during the armistice, of which 80,000 continued to work, filling trenches and damaged roads, or reloading large quantities of materials that had previously been transported to the front line and transporting them back to Britain. Most of these laborers were not repatriated until around 1920. On the French side, Chinese laborers were not able to return home until 1922.

This is also the reason why Sun Qian did not find Chinese laborers on the front line.

Since then, Sun Qian and the two have started a life of two points and one line. Half a day to write a summary, half a day to go to Chinatown.

Time flies, and a month has passed in the blink of an eye.

Sun Qian's summary is almost written.

In this "Sun's Drill Code", Sun Qian expounded his tactical thinking and training plan.

First, Sun Qian clearly defined the scope and requirements of the commando unit, embodied the tactical thinking of using the small to broaden the big and defeating the strong with the weak, and flexibly used the commando to strike at the enemy's weak links and logistical supplies. In addition to this, there are tactics to disrupt the enemy's command system and come up with a decapitation operation. Cooperate with frontal forces to contain the enemy's vital forces. Always grasp the initiative in the war, grasp the battlefield situation, and act as the eyes of the large army.

Sun Gan's definition of a commando is the eyes and sharp blades of a large force, achieving tactical superiority and strategic leverage.

The second part revolves around the training and composition of the commando team.

First of all, in terms of training. All forms of training for commandos must be carried out in accordance with reality, and there are clear tactical requirements in terms of personnel and weaponry. First of all, in the selection of personnel, commando personnel should be supplemented by soldiers who have participated in actual combat for at least one year and have rich battlefield experience, mainly soldiers with special skills; after these personnel are selected, they must also undergo all-round training, ranging from the cultivation of tactical execution ability to the practical operation of weapons to psychological quality, and so on. Only a soldier who has passed these trainings can become a qualified commando. After all this was completed, Sun Qian estimated that it would take at least a year.

Secondly, the aspect of the composition of the commandos. Assault teams will be more in the form of tactical squads, and if the mission requires it, several or even a dozen squads can be brought together to operate. The team members have a clear division of labor and complement each other, corresponding to the needs of the task, and the members can be freely combined.

Finally, in terms of weapon selection, it provides a variety of options. For example, submachine @ guns for raids, short-barreled shotguns and flame@jets for trench warfare, etc. This requires commandos to be versatile and able to use a variety of weapons.

Of course, these are the most basic concepts, and when applied to actual combat, whether they are suitable for the battlefield remains to be reviewed.

Sun Gan's real idea was to build an all-round army, which could do everything from heaven to earth and to the sea. He also planned to establish this force abroad, and Sun Gan, who had witnessed the coalition forces listening to each other, knew that if he did so, he could only dig a hole for himself with his domestic foundation. Although Sun Qian is not a nationalist, he still knows the most basic distance and proximity.

The third part is the core goal of the current stage.

Neither men nor weapons are lacking in the coalition forces, as long as he asks for them, the coalition forces will definitely be able to solve them for him. What he wants most now is the support of formal military theory, and the current summary is a summary of a tactical nature, and there is not much theoretical support, which is also a problem faced by most of the new military means in the early stage, and if he wants to form a theoretical system, writing a book and writing a biography is not something that Sun Qian can complete alone, even if he adds Sun Xing, so he plans to wait until the end of the war, and then discuss it with Every.

In this way, Sun Gan perfected his "Sun's Discipline" as much as possible, became friends with the laborers, and used his identity to help the Chinese laborers solve their difficulties. When they returned to the front again, Sun Qian and his wife had become friends with many people, and when they returned to China, many labor brothers returned to China with them, and finally joined Sun Gan's group, and many of them eventually became good generals on the dominant side.
