In ancient times, there were many kinds of camps.

The most common of these is the marching barracks.

This type of camp was temporary, and was only used for the rest of the army at night, or for a short period of time, and was generally used for a stay of less than ten days.

This type of camp is the simplest, you don't need to set up a tent, it depends on the location and the weather.

Generally, as long as it is not the rainy season and spring and winter, it is rare to stop and rest at night.

Even if it is built, it will not be built according to the requirements, because it will be too troublesome to put it away early the next morning and continue to hurry.

Everyone has been gone all day during the day, and who doesn't want to rest a little more at night?

In addition to this, the outermost part of the camp is surrounded by vehicles, which is the proposed wall, to prevent large beasts, as well as enemy attacks at night.

The most important thing is to prevent wild beasts, and there are very few night attacks these days, so everyone's defense is not so sufficient.

Otherwise, how could the Han army burn Sima Xin's grain and grass so easily?

The other is this kind of camp of the Chu army opposite Han Xin.

Compared to the marching camp, the level of this camp has increased.

According to the regulations, tents were erected, and there were also wooden walls, and the wood of the walls was thigh-thick, and it could not be broken by manpower.

Unless you push the siege car to crash into a hard hit.

The level of protection of this kind of camp is also a little more advanced, and the walls are not tight.

Standing outside, you can even see the inside, between the two stakes is about the width of two palms side by side, and every half a meter up and down, there is an arm-thick piece of wood fixed horizontally to prevent a single stake from being knocked down.

If you encounter an enemy situation, you can place the shield in the gap, and the person crouches behind it, and through the gap to carry out long-range strikes on the enemy outside.

And when the enemy approaches, you can use spears and other weapons to stab, and the effect is very good.

Dealing with this kind of camp, it is not difficult to say, but it is not easy to say that it is simple, he only belongs to a medium level of difficulty.

And the most difficult kind is to add configuration on top of this version.

At the top, the spurs are fixed at a 45-degree angle to the stake to prevent the enemy from climbing up.

In addition, at the top, a two-story position will be built, and some of the higher specifications will even have a three-story position.

In fact, it is to build a platform out of wood, and when the time comes, it will be divided into two layers and three layers to defend at the same time.

And if you encounter this kind of camp, if you want to take it, you have to leave a lot of people.

The Chu army may not have expected the Han army to come, let alone to come so quickly.

But they also don't seem ready to continue upgrading their camps.

Soon, several hundred-man squads left the camp with their shields in hand.

The front ten people are side by side, the shields are next to each other, and the front shield is on the edge of the left and right shields, and when the force is applied, you can use the strength of the two people next to you to counteract the attack on the opposite side.

The left and right sides continue to rely on their respective left or right shields, and the two sides are defended by five shields in the same way.

The rest stood in the middle and raised their shields above their heads.

To describe it more precisely, it is the Wang Ba Shell Sub-Formation, when encountering such a formation, even if it is a marksman, it cannot be guaranteed that every arrow can be shot through the gap.

The speed of the shield array is very slow, because it is necessary to cooperate, and people who have not been trained really can't play this kind of technical work.

Don't think that the shield array has no attack power if it makes itself look like a king.

The Chu army on the opposite side had already reacted, and when he saw the shield array, he couldn't help but be stunned.

It seems that I can't understand what the Han army on the other side wants to do?

"Just a few hundred-man teams dare to attack? Who to look down on? The general of the Chu army looked at the opposite side angrily.

So after the shield array entered the firing range, he waved his big hand and coiled him......

For a moment, arrows from all directions shot at several shield formations at the same time.

Who's going to let them into range?

From the outside, the scene is spectacular.

Some of the arrows were stuck directly into the shield, while others were bounced off.

There was a clanging sound, and more and more arrows were fired at the shield array.

But the effect is ......

It can only be said that it is just a desire for comfort.

If you want to be accurate in large-scale arrow attacks, you don't have to think about it, it's more about completing regional strikes.

And behind the formation, looking at the performance of several shield formations, Han Xin said that he was very satisfied.

"Yes, I didn't expect that just a few days of training would be able to have such a degree of cooperation!" Han Xin praised with satisfaction.

To date, on average, each shield array has been attacked by no less than a thousand arrows.

But so far, no one in the shield has fallen.

If it weren't for Han Xin's personal training, even he himself would find it hard to believe that the hundred-person shield array in front of him was actually composed of novices.

"Hehe, general, I didn't expect them to be so calm on the battlefield, especially the one on the right, you see......" Tian Zong, a pro-soldier next to him, pointed to one of the shield formations and smiled.

In order to train these shield arrays, he did not put a lot of effort into it.

Fortunately, the results are good, and these people are still quite competitive.

Han Xin focused his gaze on the shield array on the right and looked at it carefully for a while.

Sure enough, I noticed something different.

"Yes, the pace of travel is uniform and neat, the height of the shield from the ground is just right, and the cooperation makes people unable to find problems."

The biggest difficulty in shield training is coordination.

And the shield array that works well and the shield array that doesn't work together are completely different endings on the battlefield.

A shield array with tacit understanding, when it comes to the battlefield, only needs a hundred people, and it can drag five hundred or even a thousand people.

If it is a thousand-person shield array, then the effect is even better.

Not only can it make the opponent helpless, but it can also do a lot of damage to the opponent.

The shield array is not just to protect itself, but to stab the spear out through the gap, this is a hedgehog array.

The people in the formation can shoot arrows through cooperation to kill and injure the enemy at a longer distance.

And the only ones who have the ability to restrain the shield array are only two.

The first is a close-range shot in a large crossbow, relying on a strong impact to break through the shield defense and open a gap for the infantry.

The second is to rely on the impact of the cavalry to fiercely impact the shield array, and smash a gap in a way that does not count casualties.

Although it sounds cruel, it is actually very efficient, and basically a dozen or so cavalrymen can break through this defense without dying.

Of course, this is just a break, and a well-trained shield array will fill the gap as soon as possible, and then clear the cavalry that has entered the formation.

And it's much more than that, the shield array can also become a big mouth that can swallow people, watch you come, open your mouth and let it in, you come in, and then close your mouth, the reinforcements outside can't come in, and the inside can't break through the defense when they lose their speed, just wait slowly to be cleared.

However, the premise is that you can resist the pressure from the outside, because the shield array is not invincible.
