The news of the attack on the front line quickly reached the 2nd Mechanized Brigade of Nordenburg in the rear.

Brigade Commander Lawson looked at the request for help and casually threw it aside.

The staff officer at the side asked, "Brigade Commander, regarding the friendly forces' request for assistance, shouldn't we send support?"

Lawson sneered and said, "Why rush? The enemy's attack has only just begun."

"Intelligence from Gasu's field regiment on the front line shows that the enemy has launched an air strike," said the staff officer.

Lawson shook his head and said, "Send them a message and tell them to hold on!"

"Don't even mention it's just an airstrike now. Even if the enemy deploys mecha units, stop them!"

"I don't believe the enemy is stupid enough to ignore the easy road and attack those two valleys first!"

The staff officer responded loudly: "Yes, Brigade Commander, I will notify them right away."

Lawson nodded casually and continued to look at the holographic map in front of him.

Now both sides seem to be fighting in a stage full of fog of war. Because there are no satellites in the sky, they can only rely on reconnaissance planes to detect the enemy's movements.

However, the following three forces, including Li Xin, do not have such air units.

Li Xin is still better off, at least he still has an aviation regiment under his command. The three forces are really miserable, with no air power at all.

The Second Mechanized Brigade would communicate with the commanders on the front line every once in a while.

Always keep abreast of the battle situation on the front lines.

On the other side, after the feint attack began, Li Xin also began to arrange troops to attack the enemy positions in Xislan Lake.

The first attack was still long-range artillery strikes.

An entire howitzer regiment was deployed behind the attacking forces. These were large-caliber howitzers. The smallest caliber was 152mm, and the larger ones were even 210mm.

The range of these howitzers usually reaches more than 30 kilometers, and the range of the 210 caliber howitzers is even nearly 50 kilometers.

In addition, the artillery positions arranged by Li Xin are all in the direction of the plateau. When attacking from high and low, the range of this artillery fire is greatly increased.

These artillery positions did not even have shelters or preparations to move at any time.

Because the enemy's artillery counterattack was impossible to hit, even if the howitzer position was calculated through reverse calculation of the artillery fire, it would be useless if it could not hit.

Li Xin inside the mecha said in a deep voice: "Order!"

"Long-range artillery fire begins. Give the enemy some eye drops first!"

"Yes! Supervisor!"

Soon, the order to bombard the artillery and the coordinates of the required bombardment locations were transmitted to the artillery positions in the rear.

The howitzers of an entire artillery regiment began to get busy, and the artillerymen at each howitzer position began to adjust the firing parameters.

"boom!!"

Each position fired a test shot, and the shells streaked across the sky, making a whistling sound in the air, and then fell to the ground with a bang.

“Boom!!!”

The explosion of a shell of this caliber is different from the explosion of a mortar or small-caliber artillery equipped by the infantry.

A simple 152mm caliber artillery shell uses the latest chemical explosives, and the explosion radius is nearly 50 meters.

The effective killing range is almost as large as half a football field.

Within this range, if people are not protected and are not in shelter, they will basically be killed or injured.

The fragments produced by the explosion can easily penetrate the human body, and the shock wave can even knock people away and destroy their internal organs.

This kind of explosion can easily create a crater two or three meters deep and six or seven meters in diameter in soft soil.

Even in this semi-frozen soil under the plateau, a crater about two meters deep and five meters in diameter can be blown out.

As for the 210mm caliber artillery shells, there is no need to mention their power. With a larger amount of explosives, the explosive power is naturally greater.

The shell alone weighs 93 kilograms. Not to mention the explosion, even if it is fired from 40 to 50 kilometers away and falls from the sky, it can create a big hole.

"call out!!!"

Intensive artillery fire began, and the whistling sounds of incoming shells continued to appear in the sky.

Every scream sounded like the roar of death, and the soldiers stationed there were terrified.

“Boom!”

“Boom!!”

Inside a trench, an anti-artillery shelter was built using thick planks.

Seven or eight Dewan Technology infantrymen were hiding under this cover.

An infantryman said, "How long will this bombardment last?"

"Hurry up and get the infantry up! I'll use my rifles to riddle them!"

Another person laughed and said, "Just you, just don't wait until the enemy comes and you pee your pants in fear."

Compared to the two who were joking, there were two soldiers who were obviously much more nervous.

They looked around with uneasiness, listening to the thunder-like explosions around them. Every explosion made their bodies tremble.

Obviously, these were soldiers who had never been to the battlefield, and they were very nervous facing the artillery fire.

Someone once said that new soldiers are afraid of artillery and old soldiers are afraid of machine guns.

There is actually a reason for this. Because of the artillery fire, the veterans who were killed in the explosion could not speak.

Those who have been attacked by heavy machine guns may still be able to escape.

The survivor bias made the veterans feel that artillery fire was not as threatening as heavy machine gun fire.

Secondly, due to the advancement of technology, the power of artillery has become greater.

An old soldier comforted the new recruit beside him and said, "Hahaha, stop shaking your legs. You look so nervous. Our bunker is well built. Even if a shell lands next to it, it won't be a problem."

The recruit seemed to be less nervous after hearing this. His trembling legs stopped shaking and he asked, "Really?"

The veteran pointed to the concrete slabs overhead and said, "You know how thick this stuff is? One layer is thirty centimeters. If we stack two layers on top, there will definitely be no problem!"

The recruit's heart calmed down a bit. He put down the gun in his arms and was about to take out the water bottle to drink some water to relieve the pain.

"call out!!!"

In the air, a shell cut through the air, emitting a terrifying whistling sound, and attacked again.

Under the shelter, the old soldier's expression changed when he heard the shrill sound, and the panic on his face was beyond words.

Before they could react, a 210mm caliber shell fell from the sky and landed directly on the side of their bunker.

The grenade smashed directly through the frozen soil and was buried deep in the soil. The next moment, the fuse ignited the explosives.

“Boom!!!”

The shell exploded directly on one side of the bunker, and it was like a volcano erupting. The reinforced concrete plates on the bunker were directly blown away, and the trench collapsed.
