The cavalry can be said to perfectly meet Dai Yan's requirements for quick reaction and striking the enemy in a short time. Moreover, when the Song State only had a small pasture, it was indeed impossible to raise a large number of cavalry.

In Dai Yan's view, when it comes to reaction speed, nothing can surpass cavalry in the era of cold weapons! Moreover, the field combat ability of the cavalry has been excellently exerted in the civil war of the entire Song State, and even in the war with the Chu State, and it has extremely strong persuasive power!

The cavalry of the Song Kingdom were basically the cavalry trained by Le Yi for Taoqiu before. These armies used to follow the training of elite soldiers, and with the experience of many wars, they are now an extremely powerful army. Now that Dai Yan has mastered the Song Kingdom, the only thing that needs to be considered is to further expand the scale of the cavalry.

For the expansion of the cavalry, there is no need for Le Yi to do it at all. In Dai Yan's eyes, Le Yi is a talented person, and he should never exist just as a cavalry commander!

In the reform of the army, in addition to making changes to the training and mobilization methods of soldiers, Dai Yan also made slight changes to the structure of the army.

In the previous wars, Dai Yan believed that the role of the General Staff was not as great as he imagined, and that it could completely formulate strategies and tactics suitable for the Song army, but it still played a role in careful consideration. In addition, he discovered a talent like Ning Yue who was suitable for planning, so he decided to keep this department.

In order to really make the General Staff play a role similar to the brain of the army in later generations, Dai Yan directly appointed Ning Yue as the Chief of the General Staff, and let him be responsible for thinking about the internal and external enemies faced by the Song State, as well as responsible for specific war planning! Of course, in order to make Ning Yue's work really smooth, Dai Yan specially authorized him to set up a special military department, the Department of Missions.

The Department of Missions, in public terms, is only an institution to promote the culture of the Song Kingdom and for outsiders to understand the Song Kingdom. However, in fact, it is the intelligence agency of the Song State! It has the right to use the resources of the Song state, investigate everything inside and outside the Song state, and carry out special operations. In the future, this institution will also become an institution with a prestigious reputation, and a staff officer like Ning Yue, his planning skills are no longer remembered, and the first thing that comes to mind when anyone mentions him is the king of intelligence of the Song Kingdom!

In the army, in addition to serving as the general staff of the thinking brain, Dai Yan has set up several other departments, which are constantly expanding to the bottom departments. Among them, the most important is naturally the actual ruling body of the army, and the ruling organ of officers, which is composed of generals, division commanders, brigade commanders, 100 generals, chief officers, and army commanders, is naturally the first to bear the brunt among them. Those who occupy their positions naturally have the power to command specific armies.

Dai Yan attached great importance to military power, so he did not appoint the commander of the entire Song army to anyone, but concurrently served by himself. As his cronies, Tang Ying and Xiao Xiang, who have always followed him, have obtained the position of commander below the commander and above the general.

The generals of the Song State were able to command an army with their own name. And the commander of the Song State has no major events in peacetime, but can command several armies in wartime, such a position is very similar to the commander of the group army in later generations!

Of course, it is indeed too much to say that Tang Ying and Xiao Xiang are fine on weekdays. Soon after, Dai Yan divided the entire Song Kingdom into two major war zones, east and west, with Danshui as the boundary. These two theaters of war were responsible for defending against the enemy in the east and west of the Song Kingdom, respectively. Tang Ying was in charge of the Western Theater, mainly defending Chu and Wei; Xiao Xiang, on the other hand, was responsible for defending the Qi state in the east, as well as the small states of Sishang.

In addition to being the staff department of the brains of the army, as the commander of the army's hands and feet and officers at all levels, there is also a very special department in the army of the Song State - the Ministry of Sacrifice.

When such a department was first established, everyone was surprised by its specific role. Because this department is so strange, it is not like the military department of the Song State, which is specifically responsible for the logistics and equipment supply of the army, but it will provide medical services to the army. It also does not have the power to formulate specific strategic plans and even command the battlefield like the General Staff and the Commander-in-Chief, but this department has the power to veto the unreasonable role of officers under certain circumstances.

At the same time, it was also responsible for the rituals of the entire army on weekdays, and even to inform the soldiers about the situation at home and abroad, as well as to teach the soldiers to learn. At the same time, under this army, there are also specific singing and dancing teams, juju teams, polo teams and many other things that enrich the entertainment culture of soldiers!

The most important thing is that the number one governor of the Ministry of Sacrifice is Le Yi!

When Le Yi was appointed to this position by Dai Yan, he also didn't understand the meaning of the existence of this department. Even to a man like him, who had a pioneering vision and even rich experience in warfare, such a department seemed completely unnecessary, and he even felt aggrieved that he had been given such a position that could not be improved or inferior.

However, no one knows better than Dai Yan the role of the Ministry of Sacrifice in the army! Dai Yan positioned it as the General Political Department of TG in later generations!

In fact, a department like the General Political Department is not original to TG, and its rudiments can be found in history. For example, when the Green Religion rose in later generations, there would be an imam in every army. These imams are not responsible for the specific command of the army, but it is one of the most important factors in the army, because it is responsible for pacifying the soldiers, controlling the spirit of the soldiers, and can greatly guarantee the combat effectiveness of the army!

Later, when the Crusaders saw the rise of the Arab Empire and became rich, they frantically ran over and plundered the European barbarians, and their army also had chaplains with the same position as the imams. The tradition of chaplains, even through the ages, into the 21st century, is still alive in the armies of the American imperialists!

This kind of department, which determines the spirit and morale of the soldiers, and is responsible for keeping the army out of control at critical moments, can hardly and never disappear in the army, because its importance is irreplaceable!

After the establishment of the Ministry of Sacrifice, it was also responsible for the usual sacrifices in the army. The usual entertainment of the soldiers, the comfort in times of danger, and the treatment of the wounded have almost made this unit the most popular institution in the army. However, with such a good atmosphere, Dai Yan planted a nail in it in the blink of an eye and destroyed it completely: a supervision department was specially set up, as well as a military tribunal specially responsible for judging soldiers and officers!

In Dai Yan's view, the army is a combat organization, soldiers can have good brotherhood with each other, and officers can also have "benevolence" to soldiers, but the military institutions must be cold-blooded enough! For the whole institution is not engaged in good works, but murderous trades!

A strong organization, if it wants to have combat effectiveness externally, must also have strict requirements internally! Just like the Qin State, the only law in its country is followed, and if the law is violated, in addition to the monarch, no matter how noble the nobles are, they must be punished by the law! This is the cold-bloodedness that it must have as a war machine!

In the army outside the Song Dynasty, Dai Yan basically did not make much changes. Like the land of the East China Sea, the army that belonged to the nobles of the East China Sea was privately owned, and Dai Yan did not forcibly take it back, but allowed them to organize, train, and expand on their own.

For these armies, Dai Yan will only integrate them together in times of war, when they are forcibly requisitioned, and match them with specific institutions to assist the local army in combat. This series of changes also made the army of the Song Kingdom, which originally had many tricks and many political departments, completely straightened out!

Under such a simple composition of two sets of teams, the army in the Song State was constantly changing in a way that was changing with each passing day. The armies outside the mainland also began to gain a firm foothold in the East China Sea, and continued to expand southward along the coastline and even the canal channels dug by Wu Wangfucha with the assistance of sea ships.

The land troops of the entire Song State continued to get stronger and stronger, and the strength of the entire Song Kingdom also became stronger, making Dai Yan's heart more and more stable.

As for the sailors of the Song Kingdom, when the great threat to the entire Song Kingdom was now Qi, Wei, and Zhao located in the surrounding areas, Dai Yan integrated the originally extremely powerful Taoqiu Sailors into the Song Navy. These sailors roamed on the three most important rivers of the Song Dynasty, Surabaya, Danshui, and Suishui, as well as Jishui, which bordered other countries in the north, and became the "Great Wall on the Water" to defend the Song Kingdom from foreign invasions!

Because in this era, there are only a few countries such as Yan and Qi, and after dividing the sea border with Qi before, the vastness of the sea area did not allow the two countries to play a specific conflict. Therefore, Dai Yan has no plan to focus on developing the navy at all. Dai Yan also adopted a laissez-faire attitude towards the navy sailing on the sea.

Because of the discovery of new overseas territories, they could have the right to name and even enjoy part of their property rights, and the merchants of the Song Kingdom have always had a high enthusiasm for overseas development. With the powerful existence of Qi in the north, merchants expanded to the south, and their work rapidly expanded the geographical scope known to Huaxia.

Originally, the southeast, the farthest location in the south that people can know, that is, the land of Longxing, where King Goujian of Yue started. However, the merchants of the Song Kingdom saw the vast sea tide south of the river, and easily reached the hinterland of the Yue Kingdom.

And as they continued to explore the south, they were islands one by one. And when an explorer discovered that the south had islands no less than the size of the Song Dynasty, he was even more surprised!

On these islands, there are all kinds of resources suitable for the Song Kingdom. The huge profits obtained from overseas exploration once again stimulated the people in the Song Kingdom, making people go to the south and overseas even more frantically!
