Jing Wen saw that Anshi City was actually playing "artificial rain enhancement". Now Jing Wen really had no good solution. After all, if you still want to rely on this explosive pack to blow up the city wall, then the water will be enough to extinguish the fuse of the explosive pack. And if these were the only means, it would be impossible to blow up the city wall. If the city wall cannot be blown up, the only option is to use soldiers to climb up the ladder and then attack the city to conquer Anshi. And Anshi can be said to be the last city nearby, but it is this last city that is troubled. And Jing Wen also knew that the city lord of Anshi was a veteran and very good at defending the city. The flying thunder cannon has not been used many times, but this guy immediately figured out a way to crack it. And his mind was moving very fast, and he immediately thought of artificially increasing rain to extinguish the explosive packets of these flying thunder cannons. And this guy is very shrewd, if ordinary means are really not his opponent. So Jing Wen sat down and meditated, and then thought about how to deal with this group of enemy troops. After all, if Anshi cannot be conquered, the enemy will be like a wedge inserted into the Tang Army's occupied area. This is very dangerous, so Jingwen is helpless. Therefore, Anshi must be captured, otherwise it will be very dangerous for the subsequent conquest of Goguryeo. ¡°Brother-in-law, please think of a way!¡± Dugu Mou said. The commander of the artillery regiment next to him also said: "General, what can you do?" "What can I do?" Jing Wen said. The artillery regiment commander immediately said: "It would be great if we could fire artillery shells and attack the city at the same time!" And Jing Wen immediately said: "Isn't this infantry-artillery coordination?" Jingwen heard the artillery regiment commander's words and suddenly thought One method was found, that is, infantry and artillery coordination. Infantry-artillery coordination has existed since the invention of cannon until later generations. The coordination of infantry and artillery means that the artillery suppresses the enemy, and the infantry follows suit. The artillery continuously fires to cover the infantry charge, so that on one side they can kill and injure the enemy, while on the other side the infantry also charges according to the impact point of the artillery fire. In this way, the enemy's infantry will be suppressed by artillery. Unable to resist. As for your own infantry, you can take advantage of this moment to rush forward, and then after the artillery cover is over, your own infantry will be right on top of the enemy's infantry. This is the so-called infantry and artillery coordination, but it is a very cruel method. But although infantry-artillery coordination is powerful, the conditions for its implementation are also very high. This has very high requirements for the quality of soldiers, that is, artillery must attack accurately, and infantry must also be suitable and have the courage to charge. If the infantry did not have the courage to charge when the artillery was firing, it would be impossible to succeed. As for the artillery, they must also avoid blowing up the infantry on their side if the cover is not available. On the contrary, it will end up being blown up by one's own cannonball, which really means there is no place to cry. So when Jing Wen heard about the infantry and artillery coordination, he was actually very upset in his heart. Because with the current quality of soldiers, can infantry and artillery coordination be implemented? Even in later generations, infantry and artillery coordination will be a huge problem. What if you are bombed by your own cannon? Who will bear the responsibility then? Being accidentally injured by one of your own is a very serious crime. If you are killed by the enemy, you are a martyr and a hero. But he was killed by his own people. Whether they are considered martyrs and whether their families can receive pensions is also a big question. Maybe, they will all be sent to the military judge for processing. But for now. That is to say, only the coordination of infantry and artillery can best hit the enemy. If they attack the city directly, the Goguryeo soldiers can come out to prevent them from attacking the city. But if artillery shells are fired, it will inevitably cause those Goguryeo soldiers to avoid the artillery shells. If you can charge while they are avoiding the shells, it may have the best effect. The firing just stopped at that time. Then one of your own people immediately catches the enemy off guard, which can really be fatal. As soon as the artillery fire ended, the enemy arrived in front of him. Not even having time to prepare, this is quite miserable. Therefore, infantry and artillery coordination was an artifact in ancient times, but whether it can be used currently is still a question. The cannon was just invented by Jing Wen not long ago. If infantry and artillery coordination is used, all the theoretical foundations have not been established, and there is no experience at all! "Brother-in-law, do it! When they fired the artillery shells, I led the troops to follow and charge. I think I should be able to do a good job!" Dugu Mou said. The commander of the artillery regiment said: "General, I think we can still do it. At worst, we will be sent to the Military Development Office. What can we do? So, let's use it! If we can find a way, then It will be helpful for our future cooperation between infantry and artillery on the battlefield. If we don't succeed, then we will have to do it anyway if we want to open up.?Someone died. If I can exchange my sacrifice for experience, it will be worth it! " And Jing Wen immediately shook the artillery regiment commander's hand excitedly and said, "The awareness is so high! What's your name? "The artillery regiment commander said: "My name is Zhou Bin. " Since Dugu Mou and Zhou Bin also agreed to use infantry and artillery to coordinate the attack, Jing Wen began to think about how to carry out infantry and artillery coordination. The reason why Jing Wen agreed to infantry and artillery coordination was actually because the enemy's reinforcements were about to arrive. If Anshi cannot be captured within two days, the enemy's reinforcements will also come to Anshi to attack, which will lead to a decisive battle. If the Goguryeo soldiers in Anshi and the reinforcements from the rear of Anshi join forces. Jingwen is really unlucky to attack him, so he must deal with Anshi within two days, otherwise it will be impossible to face the enemy's attack from both sides, and he will really have to retreat. "Okay. , we started with some preliminary training, and then carried out infantry and artillery coordination! " Jing Wen said. Jing Wen also began to let these soldiers start preliminary infantry and artillery coordination training. As for the training methods, Jing Wen also roughly mastered it. Because Jing Wen was also a little military fan in later generations, he was very concerned about infantry and artillery coordination. He still has a certain grasp of the basic principles and methods. So he has a way to train this infantry and artillery coordination. If he doesn't even train some basic training, it will be really tragic if the soldiers are allowed to perform infantry and artillery coordination. (To be continued, please search Piaotian Literature.
