The formation of the heavily armored cavalry is generally a horizontal formation, and dozens of horse bodies should be maintained between each horizontal team to ensure that the horses behind will not be "rear-ended" because they cannot stop. In this way, if you want to spread out 5,000 heavily armored cavalry, you need a large battlefield area. If the length of the attack surface, that is, the enemy's weak part, is 500 meters, then it is a horizontal team of 200 knights, a total of 25 teams, and this phalanx will have an area of 500m ×1200m, and if there is not enough heavy infantry and light cavalry to cover this charge, the flanks will become the target of the enemy's heavy armored cavalry. Heavy armored cavalry is basically a one-hit kill, and after a charge, it must use a large radius of maneuver to reverse the charge. In the course of the movement, slowing down is suicide, maintaining speed requires a large turning radius, and if you encounter various obstacles against cavalry in the enemy's position, you will be broken up in formation. Once a few heavily armored cavalry are surrounded by infantry, they can easily be slaughtered or captured. Heavily armored cavalry cannot be used for pursuit, their war horses can only be used for sprinting, they will lose physical strength if they exceed a certain distance, their momentum is large and they cannot turn flexibly, their field of vision is small and they are easy to be ambushed, and they are not flexible enough to adapt to hand-to-hand combat and capture the enemy. Ordinary bows and arrows cannot damage heavily armored cavalry. Knights' weapons were usually long spears and spears, as well as long and heavy knives and axes. Use a spear for the first charge, and a knife and axe for the return.

Based on the understanding of the above heavy cavalry, Guan Yu has built such a strong force through some knowledge about heavy cavalry that he has learned from books and films in modern times, combined with his own combat experience for so many years. This heavy cavalry numbered about 3,000 people, but these 3,000 people cost the manpower, money, and material resources of the entire 30,000 infantry. These 3,000 heavy cavalry are enough to equip a team of 30,000 people, and Guan Yu would rather spend a lot of manpower, money, and material resources to build such a heavy cavalry. has his own considerations

Guan Yu built this heavy cavalry, fully combined with the advantages and disadvantages of Chinese and foreign heavy cavalry, learn from each other's strengths, give full play to the advantages of heavy cavalry while making up for the disadvantages of heavy cavalry as much as possible, he carefully built this heavy cavalry personnel are all selected from the elite of the light cavalry, they have abundant energy and physical strength, combat effectiveness is considerable, Guan Yu's heavy cavalry equipment naturally did not say that all of the armor and weapons made of high-quality steel materials, heavy cavalry carry long and short weapons. With spears and shields in their hands, and knives and axes on their bodies, they can adapt to the needs of the battlefield at any time, and the heavy cavalry is fully armed with copper walls and iron walls against the opponent, allowing the opponent's archers to shoot, and not hurting the heavy cavalry at all.

The reason why Guan Yu built this heavy cavalry is also based on the advantages of Li Daoxi's Liang soldiers' bows and crossbows, and the crossbowmen of Li Dao's army are very powerful, not only the bows and crossbows are good, but the bows and arrows are extremely sharp. This is the true biography of the Huns, the last time he was injured was to eat the loss of Li Dao's bow and arrow, Guan Yu after repeated pondering, determined to build this batch of heavy cavalry to deal with Li Dao's crossbowmen. If the battle began, this heavy cavalry would line up and smash Li Dao's crossbowmen, and after tearing all the crossbowmen in front of Li Dao's formation, a large number of light cavalry could rush towards the enemy with lightning speed. In this way, Li Dao's army has no advantage. In front of Guan Yu's army, there was a rabble.

Of course, Guan Yu carefully built this strong team, not only for this engagement, but also for long-term operations in the future, which can play a role once and for all. As long as the opponent does not find enough countermeasures, Guan Yu's strong team can rampage and unscrupulously disrupt the opponent's army lineup. Guan Yu has high hopes for this heavy cavalry, hoping that this team can give full play to his advantages, because in this era, his heavy cavalry is definitely a first, and it also costs a lot of money, and there is not enough manpower, material and financial resources can not support the expenses of such a huge team in any case, just this war horse is all high-quality Western Regions war horse, the advantage of this war horse is strong physical strength, good endurance, and can accelerate with weight, Therefore, it is very applied to the combat equipment of the heavy cavalry, it can be said that this heavy cavalry represents the trump card of Guan Yu's army from material allocation, staffing to the selection of war horses, how can Guan Yu not have high hopes for him?

The introduction of heavy cavalry is also an innovation in the method of warfare, if the test is successful, it will be able to achieve twice the result with half the effort, and achieve victory in the war at the minimum cost, which seems to cost a lot, but in fact, if the battle is successful, it can greatly reduce its own attrition and combat attrition, which is a challenge to traditional warfare, and the victory of "destroying 10,000 enemies and losing 3,000 self-losses" will be gone forever. This is also an important reason why Guan Yu moved out of the heavy cavalry this time.

In addition to moving out the heavy cavalry in this western expedition, Guan Yu also made great efforts to build a heavy infantry, the so-called heavy infantry

According to the difference in equipment, it can be roughly divided into three types:

1. General hoplite with shields and one-handed weapons, which are relatively adaptable to the battlefield and have a wide range of uses.

2. Spear-based spear and super-long spear-based pike-infantry, which generally form a phalanx group to fight, has high requirements for training, and is a very considerable type of group combat effectiveness, and is the most powerful force for infantry to fight cavalry.

Heavy infantry has higher requirements for the quality of soldiers and equipment performance, and is the elite force in the infantry, and can play an excellent role in both siege and field battles.

Excessive armor will lead to a decrease in movement speed and an increase in physical consumption, making it unsuitable for pursuit, reconnaissance, harassment and other tasks, and it is difficult to exit the battlefield in time when defeated. It is still in a passive position in the battle against the cavalry, and the requirements for the group are quite high, and if the group advantage is lost, it will inevitably suffer a fatal blow.

When fighting, soldiers usually formed a rectangular phalanx with at least ten rows and a larger number of columns. During the battle, the soldiers of the first five rows stretched their spears forward to form five long rows of spurs, and the soldiers in the back row raised their spears upward, always ready to use the butts of their guns (above), and to replace the soldiers of the first row who died in battle. At the same time, the infantry raised their shields in front of them and pressed them close to each other, even the soldiers in the back, rather than as depicted in the film

Raising the shield above the head doesn't have much effect, and it also wastes a lot of energy.

The key to the application of phalanx tactics lies in the coordination and unity of the entire phalanx. A phalanx is a close fighting collective, and the actions of each person in it must be coordinated, otherwise the phalanx is like a plate of scattered sand and has no combat power. On the contrary, a phalanx full of courage, unity, and coordination is quite strong in battle, Guan Yu worked hard to build this heavy infantry side of 10,000 people, equipped with this team of more than 10,000 people, the cost of money is twice that of the general infantry, Guan Yu's heavy infantry is actually the previous research of the "Eight Gates Golden Lock Array" of the copy, he re-armed the soldiers of the previously trained Eight Gates Golden Lock Array, and the result was to form such a heavy infantry pair, Guan Yu's heavy infantry team built this time is actually based on the original training of the "Eight Gates Golden Lock Array" The infantry's weapons were re-equipped, so that the combat effectiveness of this heavy infantry team was greatly enhanced, and the candidates for this heavy infantry team were also the soldiers of the previously well-trained "Eight Gates Golden Lock Array", these soldiers were equipped with heavy weapons this time after strict training, and their combat effectiveness should be extraordinary, Guan Yu also gave high hopes to this team, hoping that he could play his due role in this battle

Guan Yu's army of more than 100,000 people marched westward, the army marched all the way, the speed of the march was very fast, the team only rested for 5 hours every day, and the rest of the time was spent on the march, so the army quickly gathered at the gateway to the east of Chang'an - Feng Yi, this Feng Yi's county guard is Guan Yu's previous brother - Zhang Ji, Guan Yu's mind quickly appeared in the scene of marrying Jinlan with Zhang Jiyi, when Zhang was so high, so unruly but finally conquered for himself, Since then, the two have formed brothers who are like each other, this time the soldiers are in the city as brothers, Zhang should not be difficult for himself, maybe he will also echo himself, this Feng Yi will not be self-defeating, he can take the gateway to the east of Chang'an without a single soldier, Guan Yu thought

The army quickly marched to the east of Feng Yi's county city, and came to Feng Yi's city, but saw that Feng Yicheng was still as tall as ever, the city was stable, solid as gold, in the south of Feng Yicheng was the turbulent Weishui River, Guan Yu came to Feng Yi with the army, but saw that Feng Yi's city gate was closed, the city was full of soldiers, the guards were tight, and the fortifications of the city defense were obviously strengthened a lot. I am writing to you to arrange for the archers to shoot my handwritten letter to the city, and ask the guards of the city to pass it on to Zhang Ji, I think Zhang Ji will open the city gate after seeing my letter, and will gladly come to vote! ”

"Whoa!" Zhou Cang commanded.

Guan Yu immediately wrote the letter, Zhou Cang immediately ordered the archers to shoot to the city, at this time I saw a number of heads suddenly appear in the city, accompanied by the appearance of human heads, "Ha Lu Ha" A burst of laughter followed, Guan Yu fixed his eyes and saw that a lot of people appeared in the city at once, two of the generals poured out, one of which Guan Yu recognized as Xu Rongye, the general under Li Dao, and the other looked strange.
