The power of artillery depends on the caliber of the artillery and the muzzle velocity of the artillery shell.

The larger the caliber, the greater the power.

When the caliber is the same, the higher the muzzle velocity of the artillery shell, the greater the power. The power here is mainly to increase the penetration.

The former is widely known.

But relatively few people know about the latter.

The reason is also simple,
Increasing the caliber of a cannon is technically relatively simple and popular. After all, the thicker the barrel, the greater the visual terror, the stronger the explosion, and the more terrifying the destructive power.

The effect is immediate.

However, the larger the caliber, the weight of the gun will also increase linearly and exponentially.

However, increasing the muzzle velocity of projectiles is technically difficult and relatively costly, and the effect of increasing the power is far less significant than thickening the barrel.

Moreover, the weight of the artillery has also been improved.

Fortunately, there is one of the simplest ways to increase the muzzle velocity of artillery shells, and that is to increase the amount of powder.

More propellant!

So··
"No wonder."

When they saw this artillery, everyone in the New Second Regiment suddenly understood.

No wonder the regiment leader dared to wait until the artillery of the independent regiment completely destroyed the Sha'ao stronghold before attacking.

A cannon with only a 75-caliber caliber has a propellant equivalent to that of a 105-caliber cannon. Everyone can imagine the penetrating power of this artillery without the need for specific data.

A mere stronghold in Sha'ao is absolutely unstoppable!

"Prepare."

Seeing the new artillery gradually move to the predetermined gun position, everyone's expectations gradually rose in their hearts.

According to the regiment leader's wishes, this artillery will destroy the Sha'ao stronghold bit by bit, just like breaking bricks, breaking it into powder bit by bit, and then they will start to attack.

In other words, just clean up the battlefield.

Without stronghold fortifications, can these Japanese soldiers stop their three battalions?

In this process, the third battalion only needs to block the Japanese counterattack.

So··
The third battalion commander and several company commanders couldn't help but look at the two 12.7mm heavy machine guns that had just been issued from the brigade headquarters, with an effective range of 1,800 meters and stable ballistics.

The enemy's fire reconnaissance at the Sha'ao stronghold has been completed.

The only threats to this heavy machine gun were two Type 92 infantry cannons and two Type 41 mountain cannons.

They are all located in the stronghold, arranged in fixed positions, and used as fixed firepower points.

The Japanese seem to be very superstitious about this concrete tomb.

Although it can be launched for combat, it will take time. The new 75mm artillery will not give the Japanese time, and will quickly and decisively knock out the strongholds containing Japanese artillery.

As long as these two heavy machine guns are placed on the high slopes on both sides of the stronghold to form cross fire,
In addition to the 60 and 82 mortars belonging to the third battalion, more than Czech machine guns.

The Japs in the Sha'ao stronghold are the turtles in the urn.

boom··

In everyone's imagination, the first artillery shell accurately hit the main body of the stronghold.

···
"Captain, the Eighth Route Army is here."

"Stupid Tubalu."

Inside the sand valley stronghold.

Seeing the Eighth Route Army approaching outside, Major Ben's tone was disdainful.

When the New Second Regiment approached the Sha'ao stronghold, the reconnaissance troops he deployed discovered it. Through equipment, mules and horses, etc., they also knew that the Eighth Route Army troops coming to attack were very strong.

There are tons of machine guns, mortars, grenades, etc.

The firepower was greater than that of the brigade he commanded.

There are also more troops.

In a field situation, his garrison brigade had little chance of winning.

But Major Banben was still full of disdain.

What's the use of having good equipment and strong firepower?

Can you take down his sand concave stronghold?
Aren't you afraid of locust army reinforcements when they rush over in such a mighty manner?
There are as many as 50,000 locust troops stationed around Taiyuan and Yangquan. Thirty thousand locust troops can reach the Sha'ao stronghold within 24 hours, and even as many as 60,000 can arrive within 48 hours.

"They pushed up a cannon."

"Probably seventy-five caliber."

Some Japanese soldiers discovered the pushed-out PAK40 anti-tank gun.

The effective range of the PAK40 is about two kilometers. Considering the accuracy, the artillery squad of the independent regiment advanced the artillery position to a position of kilometers away from the Japanese stronghold.

Because it uses the base of the 105 artillery gun, the PAK40 is relatively large, even comparable to the weight and volume of some 75mm howitzers.

Before reaching the position, he was discovered by the Japanese.

Furthermore, the caliber of the artillery was visually measured.

Because the Locust Army really has a lot of 75mm artillery, and they are very familiar with this caliber.

"That is···"

When he saw the PAK40, although Major Sakamoto's expression remained calm, it could be seen from his tone that he felt something was wrong.

As a major, he is a graduate of the military academy.

Major Banben naturally knew the relationship between body tube and artillery power.

He saw the PAK40, the long barrel, and the unique horizontal shooting angle.

"Anti-tank gun!"

Gradually, Major Banben's tone became serious.

Seventy-five millimeter anti-tank gun.

Coupled with the technical capabilities of the mysterious forces behind the Eighth Route Army, can this artillery penetrate the 25-centimetre-thick reinforced concrete wall of the Sha'ao stronghold?

Can it be broken down?
A drop of cold sweat dripped from Major Sakamoto's forehead.

"Report to Wing Headquarters."

"Enemy's large-caliber anti-tank artillery discovered."

Pride and arrogance made Major Banben unwilling to ask for tactical guidance, that is, for help.

But the situation made it clear to Major Sakamoto that he needed to call for help.

Otherwise, the Sandao stronghold may be fine.

After all, there is only one cannon.

But the losses must have been heavy.

Fortunately, once the regiment headquarters knew that the main force of the Eighth Route Army in the Taiyue Mountains was here, they would definitely encircle and suppress them with heavy troops.

The words fell,

Boom...The Eighth Route Army's artillery opened fire.

···
"Missed!"

Beyond everyone's expectations,
Even though the target was the main body of the stronghold, even though the distance was only 1.5 kilometers, the first shell still missed.

Flying to who knows where.

"idiot."

The Major's confidence suddenly returned a little.

"continue."

The squad leader of the artillery squad of the Independent Regiment did not panic at all.

Before getting such artillery, they had only operated mortars. After getting it, the training only lasted two days before they hurriedly went to the battlefield, firing only ten rounds of live ammunition.

In addition, the position was built in a hurry.

Missing is normal.

but that's okay,

Today, they have plenty of opportunities to make mistakes.
That is to say, the error tolerance rate is very high! The monitor thought of a word the instructor said.

boom··

While thinking, the second shell hit accurately.

···
"Oh My God··"

In the rear, the third battalion commander looked at the militia transport company belonging to the independent regiment in front of him.

The corners of his eyes twitched.

The artillery squad of a new artillery in the independent regiment consists of ten people and six military mules used to tow and transport several artillery shells. The rest are militia transport teams, militia troops from the Taiyue base area.

Responsible for transporting artillery shells.

In the artillery squad, two people were assigned to take command.

It is a normal establishment in an independent group.

But what the third battalion commander never expected was that a ten-man squad with only one artillery team had a hundred-man artillery transport team and a hundred mules.

This artillery transport team has one hundred people and fifty trucks.

A total of 500 rounds of artillery shells were transported.

"Six hundred rounds!"

The battalion commanders of the third battalion fell silent.

Although the regiment commander issued an order to wait until the artillery of the independent regiment completely destroyed the bunker and gun tower of the Sha'ao stronghold before launching an attack, they had a premonition that the artillery unit of the independent regiment would have sufficient ammunition this time.

But a mere attack on the Sha'ao stronghold consumes 600 rounds of artillery shells,

It's still this kind of combat anti-artillery shells.

"It's too much."

"unacceptable."

One company commander made a gesture of wiping his forehead, seemingly crusading against this kind of behavior, but no matter how you looked at it, there was a smile on his face.

A proud, cocky smile.

There is no way to cover it up.

No, not even masking at all.

"I like."

The third battalion commander stopped pretending and just grinned and praised.

···
Amidst the joy of everyone.

One round after another, shells were fired from the PAK40 gun barrel.

Starting from the third shot, the gunner had mastered the performance of this artillery, and almost every shot was missed, accurately hitting the turret theme of the Shasuo stronghold, the bunker.

The little devils use inferior cement, plus ordinary civilian steel bars, to cast reinforced concrete bunkers, which can indeed deal with grenades.

Even 105 grenades.

After all, the grenade fuze, charge, impact angle, and large fragmentation damage are destined to have relatively poor destructive power against solid fortifications.

But the PAK40 is a well-known anti-tank gun here. It is specially designed for anti-tank and anti-bunker. It can easily penetrate the mm outer layer of inferior civilian reinforced concrete fortifications in the sand concave stronghold.

Although the destructive power is not enough,

It can only penetrate a large hole and bite off a layer of structure.

But enough!
boom!
boom!
boom···

As the shells hit one after another, the originally strong sand-shaped stronghold became like a stone mill. Although it was strong, it could only be broken bit by bit when faced with a sledgehammer.

···
"idiot!"

Inside the bunker,
Major Laiben gritted his teeth.

His eyes were red.

He was originally hidden in the main body of the stronghold, but because the enemy's artillery was so powerful, the shells could not only penetrate the 25mm concrete of the main body of the stronghold, but could even penetrate it.

Helpless, he could only move to the stronghold.

During this half hour, the enemy shelled at a rate of four to five rounds per minute, and the stronghold had been hit by nearly a hundred rounds.

Several times he wanted to rush out, launch an attack, and destroy the artillery on Tubal Road.

But reason allowed him to restrain his impulse.

He is reckless,
He is arrogant and arrogant,
But he's not stupid.

Through the telescope, he could see the machine guns in the Tubal position near the terrible artillery. He also knew that the Eighth Route Army in front of him was the main force.

There are a lot of mortars.

For the safety of the stronghold, he ordered the surrounding terrain to be leveled. Within one kilometer of the main body of the stronghold, there were flat open areas covered with barbed wire fences.

This kind of terrain is to facilitate defense and kill enemies close to the stronghold.

But I didn't expect Tubal Road to have such powerful offensive artillery.

This time, the locust army's attack was restricted.

Once they break out of the stronghold and are exposed in the open space, facing the fierce firepower of Tubal Road, his locust army of more than 500 people will be completely wiped out in a few minutes.

Wow··
Suddenly, a violent sound came,

The main body of the stronghold, which had withstood a hundred rounds of artillery shells, suddenly collapsed amid violent shaking.

After the smoke and dust cleared, only a piece of debris remained.

Major Banben's eyes suddenly turned red.

His Sha'ao stronghold, which he swore that Tubal Road would never be able to capture, was completely destroyed without even killing a single enemy.

Only the remains of bricks and tiles remained. (End of chapter)
