The battle after the position of the Vermilion Bird Battalion did not last too long, before Gao Shun and Li Tieniu had already conducted many discussions and drills on the tactics of infantry and artillery coordination, the cooperation between the Vermilion Bird Battalion and the infantry army to attack the city was not the first time, but the tactics used were definitely not called infantry and artillery coordination but sectional strikes, today is the first time this tactic has really been used in actual combat, I am afraid that it is the first time in the history of war in China, Leping is destined to be recorded in history!

Gao Lan's vanguard sent a battalion of soldiers, they quickly listed the attack formation before the Suzaku battalion bombarded the cannons, everyone knew that the first batch of troops to attack the fortified city was often the most casualties, and now this majestic queue after this battle does not know how many loyal and brave soldiers can survive, but on that young face there is only excitement and glory, to be selected by the general as the vanguard to attack the enemy is a kind of pride for them, And yesterday's one-day spectator has raised the morale of the soldiers to the peak!

About ten zhang behind them is the Suzaku Battalion Instrument Battalion Xiangyang Cannon and the large sky-bombarding cannon to build a neat position, unlike yesterday, they did not line up but crossed side by side, at night Gao Shun and others on the infantry attack formation in-depth discussion, the Vermilion Bird Battalion is also summing up the experience of the day and night battle, so that the arrangement with depth will be more conducive to the Xiangyang artillery to effectively attack the city head and kill and injure the enemy, and Li Tieniu's favorite big guy is also impressive! Everyone knows the significance of this battle, how can such an important occasion be without the existence of big guys?

When the Yan army was arrayed, the intensity of the attack on the city head paused slightly, which immediately aroused Le Jin's vigilance, the experienced generals were very keen on the enemy's attack, and Zhao Yun Gaoshun Li Tieniu was the same, General Wen Qian also did not sleep all night, in the face of the Yan army's powerful equipment continued to strike, how could he sleep, after the sky was bright, Le Jin had been observing the actions of the Yan army behind a battlement, the Liaodong army listed the attack formation by him, and the defense of the Cao army above the city head was immediately organized, In the face of the attack of the opponent's stone cart, Le Jin thought hard all night and did not come up with a good way to deal with it, the attack range of the Yan Army's Xiangyang Cannon was too far, beyond his cognition, and the destructive power of the flying stone was not something that a shield could block, so it was difficult for him to have a good strategy in such a short time, but even if he braved the dangerous rain of rocks, he would not let the Yan Army take Leping!

What the enemy is suffering, what I want, the problem that Lejin is facing now is exactly the situation that Liu Yi wants to see when he vigorously develops the equipment battalion! The Yan army's "infantry and artillery coordination" is actually only a condensed version applicable to the era of the late Han Dynasty, and for a long time his role will only play in siege operations, and it is difficult to adopt such tactics in field warfare, because the fire coverage of the bombardment cannon cannot be solved by anyone through manual equipment alone.

The artillery group in the war of the later generations will generally be far away from the main battlefield, of course, only in terms of distance, more than ten kilometers is nothing in modern warfare, but if it is a cold weapon era, this is an insurmountable obstacle, not to mention more than ten kilometers, that is, the attack distance of more than ten miles, whether it is a bombardment cannon or a Xiangyang cannon, it is impossible to do it, if you want to play a role, they will definitely appear in the sight of the enemy, when attacking and defending the city, he can rely on the advantage of range to make the other party see and difficult, but if it is a field battle, The more powerful it is, the more it will become the enemy's key target, and the difficulty of infantry and artillery coordination at this time will increase exponentially due to the change and expansion of the battlefield space, even if Liu Yi is not too optimistic about this, after all, his improvement and reform must be limited by the reality of this era, and it is just illusory if it is too rebellious.

However, it is enough to give full play to its power in the siege war for the current Yan army, just like Lejin's current situation, he can't fight back at all for the attack of the bombardment cannon, which means that if the Yan army's infantry artillery coordination can be perfected, the Cao army's guards at the head of the city must brave the rain of stones, and the simple flying stone attack defenders can not shrink without reducing losses, but with the cooperation of the infantry army, they can't hold back, and their defense against the flying stones will naturally be reduced while fighting back, and the casualties will also increase. And the use of some equipment that can cause great damage to attack and defense in the defense of the city will be greatly restricted! This will inevitably reduce the casualties of the attacking soldiers, and once this is achieved, the Yan army's tactics have already been successful!

With Gao Shun's order, the battalion soldiers who were selected as the vanguard began a swift assault, and the morale and fighting spirit of the soldiers were mobilized to the top, but the formation of their impact and the distance between each other were all regular, which was also practiced many times in the usual exercises, and the reasonable formation and the distance between the soldiers when the impact could be well avoided by the random arrows on the city, which was accumulated through countless actual combat experience.

This Liaodong Army has just rushed out like a flail tiger, one hundred and twenty-six Xiangyang artillery bombardment cannons have restarted to launch a salvo at the head of Leping City, according to the actual experience in the previous siege battles, Liu Yi and a group of subordinates summed up that the greatest damage of the defenders to the attacker is the distance in this impact, and the task of the Suzaku Battalion at this time is to do its best to suppress the defense of the opponent's city head, so that the attacking soldiers can pass this death distance as soon as possible with the least loss!

Ordering Li Tieniu's Suzaku Battalion to attack Leping City for twelve hours without interruption was by no means Gao Shun's whim, containing and harassing the enemy army was certainly an important aspect, but the more important reason was to increase the frequency and accuracy of the soldiers in operating the Xiangyang Cannon and the Sky Bombardment Cannon to suppress the enemy in actual combat by attacking the enemy for a long time! These two points play a pivotal role in the tactics of infantry and artillery coordination, and it can even be said that success or failure lies here.

"Arrows, arrows!" Le Jin shouted loudly at the moment when the Liaodong Army launched an impact, at this time he could only temporarily ignore the killing of the flying stones to the Cao army and also make an effective blow to the siege troops, each archer had a shield hand next to him to block the flying stones coming from the volley, and there were many Cao soldiers who were smashed in the flying stones, and the flesh and blood were blurred! But with the shield cover, it is finally a little better than the naked one to withstand the other party's blows, for Le Wenqian, this is the only way when there is no way, not to attack the Liaodong soldiers who are besieging the city, and let them put the ladder on the city tower The consequences will be more terrible than casualties.

Le Jin does not have the concept of infantry and artillery coordination tactics in his heart, not only him, but also many famous generals in the world except for the generals of the Yan Army will not have much understanding of this. But as a general, his intuition has already made him aware of the danger, especially after seeing the extraordinary power of the Yan army's stone cart, and then according to the attack formation that the opponent has put under the city at this time, based on years of experience and intuition in the battle formation, Le Wenqian can already roughly judge what Gao Shun's purpose is.

Under the suppression of the Vermilion Bird Battalion, although the Cao Army faithfully executed the general's military orders regardless of life and death, and dumped the arrows in his hands to the Yan soldiers who were in the impact, both the intensity and density were greatly reduced compared to the normal city defense warfare, and the stone bullets flying in the sky gave the Cao Army archers at the head of the city a huge threat, and after continuous attacks day and night, those shooters in the Vermilion Bird Battalion appeared more accurate in the control of the sense of distance, In today's battle situation, there is rarely a lack of stone elasticity, and Li Tieniu has a clear requirement for this, and he would rather go too far than fail to catch it in the case of grasping accuracy, because that will injure his comrades by mistake!

The soldiers of the Liaodong battalion in the impact continue to be shot and fall, such casualties are inevitable, even the Vermilion Bird battalion cannot completely block the defense of the Cao army, but compared with the previous impact on the fortified city, the price paid by the Yan soldiers to rush to the city of Leping today is significantly reduced, although Gao Shun's calm face does not carry some fluctuations, but there is also a sense of joy in his heart, the scene in front of him can at least prove that this tactic is effective! But then his gaze became more solemn, and the vanguard troops who rushed to the base of the city wall had already begun to erect ladders to climb the city wall, and at this time, the attack of the Suzaku battalion still did not stop, and at this time, it was necessary to continue to suppress the enemy army at the head of the city to bear a great risk of accidental injury, and this was the real critical moment.

Such a change once again surprised Le Jin, he couldn't imagine that after entering the actual siege operation, the Yan army would dare to use a stone cart to maintain pressure on the city, and the Vermilion Bird Battalion could distinguish between the comrades and the enemy's stones, but I was not the enemy, could it be that the Yan army's control of the siege equipment had reached such an accurate level? Unfortunately, the subsequent performance of the Liaodong sergeant confirmed Lejin's guess! Once again, the enemy's stone cart showed extreme precision! Of course, it was not without accidental injuries among them, but the most hit by the flying stones was the defenders at the head of the city, making it difficult for them to concentrate all their strength to carry out a strong and effective attack on the Yan soldiers who climbed up from the cloud ladder!

At the same time as the Liaodong soldiers erected the ladder, there was a moment of eye exchange between Li Tieniu and Gao Shun, Tie Niu's eyes were filled with inquiry, whether to extend the attack range slightly backward to avoid accidental injury as much as possible, but Gao Shun's eyes were so firm, increasing the attack distance can certainly reduce the probability of accidentally injuring comrades, but relatively speaking, the intensity of the attack on the enemy will also be weakened, so that they have more spare power to strike at the siege soldiers, and can also increase the casualties of the troops, compared with the two, Gao Shun would rather pay the price of accidentally injuring his soldiers, and on the battlefield for the victory of the battle, the generals of the unified army could not have the slightest weakness in their hearts.

Li Tieniu did not hesitate at all, Gao Shun's will in this battle was the military order, and he couldn't resist the order! But everyone present can obviously feel that when the Yan army began to attack the city, the frequency of the Vermilion Bird Battalion's launch was a little slower than just now, and the shooters were more focused on the launch, as a general, Jing Fang must make the necessary trade-offs on the battlefield, but the feeling of wounding his comrades under his hands is something that the soldiers of the Vermilion Bird Battalion are unwilling to accept, this is not a disrespect for military orders but a subconscious action, at this time, what they are holding in their hands is not only the launching mechanism of the Xiangyang Artillery Bombardment Cannon, There are also heavy lives of colleagues who fight bravely!
