In the era when there was no Internet, no television, and even radio was just starting, the speed of information transmission was very slow, and for the vast majority of Chinese, it was already very good to know that there was a war in Europe, and as for how the great powers fought, the situation on the battlefield was like this, and what new tactics and new weapons appeared, the vast majority of people did not know.

Even those who know something about it have seen it in the newspapers, but Zhang Tinglan is very concerned about the situation in Europe, and he not only relies on the memories of his previous life, but is now also actively searching for information, and obtaining first-hand information from officers and soldiers through the Russian smuggling network.

In addition, with the help of Fred's network, he learned about the situation on the Western Front, and reported to Zhang Tinglan regularly, he did not dare to say that he knew everything about the European battlefield, and it was almost the same.

"Students, we must first understand that the most advanced jishu of any era is the first to be reflected in the military, and a little progress of the same jishu will also bring earth-shaking changes in the battlefield situation, take the simplest cavalry stirrup as an example, after having this thing, the soldier can be more relaxed on the war horse, when there is no stirrup, the cavalry can only use short-handled weapons, such as swords, etc., so Guan Erye's Qinglong Yanyue knife is not a historical fact. In the same way, after the use of double-legged stirrups, cavalry used a large number of spears and horse lances as weapons, and this kind of cavalry was very popular in the Tang Dynasty, and also created the glory of the Tang Dynasty. ”

The question of jishu is something that the Chinese have always ignored, and the literati even dismiss these things as tricks, and when explaining the change of dynasty, they pay more attention to public opinion, saying that the number of days is cyclical, and often ignore the impact of jishu's progress. Take the Yuan Dynasty as an example, the ability to conquer Shijie relied on powerful cavalry and archery tactics, compared with knives and guns, the attack distance of bows and arrows was undoubtedly farther, and it was also more lethal.

This is arguably the strongest combination of human weapons, the composite bow and warhorse, combined with proper mangu tactics, before the advent of the age of firearms, allowed the Mongols to run rampant across Eurasia. The result is an empire unprecedented in human history.

After entering the age of firearms, the muskets became more and more sophisticated, and the range became longer and longer, and the traditional cavalry was no longer the opponent of the army equipped with muskets, such as the famous Battle of Bali Bridge. Monk Grinqin led the most elite hungry 7,000 Mongol horse corps, and launched a desperate charge against the British and French forces.

Zhang Tinglan said to all the students: "In this battle. The Mongol cavalry went ahead and followed. No one faltered, no one flinched, and their actions were definitely a model of flesh-and-bullet charge. However, the result was tragic, with less than 10 of the 7,000 Mongol horses surviving, and a large number of other friendly troops also died. And the British and French casualties were only a few dozen people, and this is the great change brought about by the progress of Jishu. ”

The trainees are listening attentively, using jishu progress as a starting point to explain the military. This is a new point of view that everyone has never heard before, and it is all refreshing, but it is also reasonable.

"The British and French armies relied on platoon guns and cannons to wipe out all the Mongol horse corps, and decades later, their platoon gun tactics fell behind again, because Jishu advanced again, machine guns appeared, and the army's firepower was unprecedentedly enhanced, originally platoon guns were to ensure the output of firepower, but now, a row of dense gunners has become the most Haode target of machine guns, and the French army was killed and wounded by German machine guns at the beginning of the war, and the corpses of the Western Front battlefield were piled up into a mountain.

Similarly, in order to cope with the powerful lethality of machine guns and new artillery, the Western Front in Europe turned into trench warfare, which simply means using dense trenches and barbed wire to form a defensive system, and soldiers hide behind the trenches like rats, pouring bullets and shells on each other. ”

Zhang Tinglan mentioned trench warfare, and deliberately placed a sand table in front of all the trainees to explain the situation of trench warfare to them.

"Mr. Fang Caixiqia explained the tactics of the sappers to everyone, but the mode he taught has fallen behind, the reason is very simple, that is, the army's attack ability is getting stronger and stronger, if it is still a simple line of defense, it can't be stopped at all, so it is necessary to implement in-depth defense, rational allocation of firepower, and the construction of fortifications has higher requirements, and the role of sappers on the battlefield is getting bigger and bigger."

When Zhang Tinglan said this, he explained to everyone in detail how to build trenches, how to build communication trenches between trenches, how to allocate firepower, and so on, and everyone listened to them with relish. Some of these trainees have participated in actual battles, and they all take this kind of defense in depth for granted.

In the past, the Chinese army often only built one fortification, as long as it was broken, the whole line was defeated, now it is completely different, the opponent's artillery attack, you can hide in the back of the fortifications, wait until the end, and then quickly to the front to meet the enemy, their own firepower configuration must also be carefully calculated, in order to maximize the damage to the enemy.

Listening to Zhang Tinglan's narration, Xiqia's face was a little unnatural, he has always been proud of his status as a non-commissioned officer, thinking that in the field of military tactics, there are almost no people who can surpass him in Fengtian, but Zhang Tinglan's narration is obviously more clever than him.

In fact, Xiqia didn't know that the Japanese often left a hand in teaching Chinese students and would not hand over the most advanced things to them. Not only military students, but also other industries, so Japanese students are the worst among modern Chinese students, and there are all kinds of people.

After returning to China, these gangs learned some specious things and did not understand construction at all, so they became professional revolutionaries, and set off round after round of uprisings with Sun Cannon.

"Ladies and gentlemen, what you get on paper is shallow in the end, and you never know that you have to do it. Let's all go to the training ground behind us and demonstrate how to build fortifications. ”

The enthusiasm of these students was also aroused, and they went to the training ground with Zhang Tinglan, at this time, not only the students of the engineering department, but also the students of other departments came over, and everyone wanted to see the excitement.

Zhang Tinglan commanded the students to dig trenches on the spot, a trench should be nearly one person deep, and when he bowed his head, he could cover the top of his head, and the width was basically kept side by side, and two people could walk.

These trainees used the new sapper shovels produced by the arsenal, which were very sharp, short and agile, and very fast to dig.

The trainees quickly dug out a trench more than 20 meters long, and according to Zhang Tinglan's guidance, they put the soil aside to form a bunker, so that the soldiers could be protected by shooting in it.

The last time Zhang Tinglan was dealing with the cavalry of the Yi Army, he built a snow ridge to block the cavalry of the Yi Army, and later found that this method could not only deal with the cavalry, but also against the infantry was also very effective.

At a distance of about 30 meters, a trench can be built to slow down the opponent, and at this time, the soldier in charge of defense can use grenades to attack, and the killing effect is very amazing.

Although there was no barbed wire fence at the training ground for the time being, the trainees also brought a few wooden stakes and pressed them to the front of the position, simulating trench warfare on the Western Front in Europe.

Some of the trainees were responsible for attacking, some were responsible for defense, and soon everyone understood the mystery of the European battlefield becoming a flesh and blood grinding plate, soldiers had to pass through barbed wire, through trenches, Zuihou also had to face machine gun fire, flesh and blood to cross hundreds of meters of murderous roads, how difficult it was.

Even if the first line of battle is captured, there are more trenches waiting for them behind, almost endlessly, and sooner or later there will be a time when they will run out of attacks on Liliang. Everyone didn't have time to lament the brutality of the battlefield, they were all thinking about how to break through the opponent's fortifications, or use more intensive fortifications to destroy the opponent.

"The Chinese often say that the weather is not as good as the location, and the location is not as good as the people, in the modern battlefield, this view is still very valuable, no matter how powerful the enemy's firepower is, as long as you make good use of the earth under your feet, give full play to the advantages of the mountains and rivers, and build the fortifications well, you can greatly reduce casualties; if you want to build the fortifications well, you must give play to the role of people and people, and all engineers and soldiers must be creative, adapt measures to local conditions, and skillfully use the advantages in their hands." Judging from the current European battlefield, cavalry has become an auxiliary service, but the value of our engineers is getting higher and higher, and they are one of the protagonists of the battlefield! ”

While explaining, Zhang Tinglan did not forget to cheer up the students of the engineering department, so that everyone was full of confidence.

"Teaching assistant, you said that Jishu's progress will bring revolutionary changes, so how do you think you can break through the trench warfare from Jishu's perspective?" Some students asked questions, and others listened attentively.

"In fact, there have been a lot of new jishu in the European theater, such as the appearance of poison gas bombs with amazing lethality, which can cause thousands of deaths and injuries to tens of thousands of people every time they are used. They applied the planes that had just appeared to the battlefield, and from now on, war was no longer a flat plane, but a three-dimensional space. For example, when we build fortifications, we should consider the needs of air defense, and if the other side uses planes to drop bombs on our heads, how should we deal with them.

In addition, the Western powers have also come up with armored vehicles, wrapping vehicles with iron armor to prevent shrapnel killing, these new things are not yet mature, but it is conceivable that trench warfare will sooner or later be replaced by a new mode of warfare, the reason is very simple, that is, jishu is constantly improving. ”

"Teaching assistant, since Jishu is so advanced, and the great powers are far ahead in Jishu, can we only be beaten forever, and don't even think about defeating the great powers?"

Zhang Tinglan also knew that the students might ask this question, and he said confidently: "Any tactics and weapons have weaknesses, and there are ways to deal with them, and those who use weapons and jishu are people, what everyone needs to do is to keep learning, find the enemy's weaknesses, and be a learning army!"
