Feng Yuanshan was no longer surprised by the new weapon that Wang Yue suddenly took out, and the senior officers of the Tiance Army were silent about it and didn't ask much, because it involved the secrets of their supreme leader, Wang Yue. Wang Yue's magic is also another important factor in their loyalty.

The 155 mm howitzer was a heavy artillery in World War II, and this thing was prepared by Wang Yue for a strong fortress like the city of Geranza.

Not only the city of Geranza, but most of the European fortresses at this time were made of granite, so they were extremely strong.

The current heavy firepower of the Tiance army is mainly mortars and recoilless guns, and Wang Yue is not satisfied with the effect of these two guns on large fortresses. Mortars, in particular, are used against infantry and enemies in trenches, as well as on walls on this plane.

The effect of the recoilless cannon against targets such as city gates is good, but the power when attacking the city wall can only be said to be average, and the city wall of this time and space is often twenty or thirty meters thick, and it is not possible to collapse in a moment and a half.

Although the 125-mm smoothbore gun of the Type 99 tank was extremely powerful, its target was not exactly a fortress, and its trajectory was straight, so if you wanted to attack the city of Geranza, which was built on the mountain, the elevation angle of the shelling might be limited.

According to the survey data, the granite fort was actually stronger than the reinforced concrete fortifications.

The 155-mm grenade directly hits the target, and the steel-reinforced concrete fortifications with a thickness of about 2 meters, which were common in the fifties and sixties, can also cause serious damage or complete destruction with a single shot, but in granite, it is a funnel pit with a radius of 1.22 meters, and a funnel pit with a radius of 1.36 meters can be blown out in the soil containing stones, and the power of the 125-mm tank gun is about two-thirds of this gun.

This is only direct damage to buildings, not counting the penetrating power of buildings and the shock wave damage to personnel.

To put it simply, a 155 mm grenade can be lethal at a distance of 6~7 meters after exploding, and it can cause serious damage to internal organs at a distance of 7~9 meters, which may lead to death; Hearing organ damage and fracture at a distance of 9~11 meters, and contusion can still be caused by a distance of more than 11 meters.

This is in the case of fortifications, if it is an open field, a 155-mm grenade has an absolute radius of destruction of fifteen meters, within which even if there is no shrapnel hit (as in a trench), you will die from the shock wave. The radius of destruction of fragmentation is 50 meters, within which at least one shrapnel is distributed in an area the size of a human body, and the safe radius of killing is 200 meters, because a very small number of shrapnel can fly to 150 meters or more,

The gun has a range of forty kilometers, and the range of a rocket extender can reach seventy kilometers. This time and space do not need such a large range, so the reconnaissance vehicles and reconnaissance radars supporting for over-the-horizon strikes are not equipped.

"Commander, everything is ready, please give orders!"

"Let's get started!"

"All of them!" Four artillery trucks fired shells at the target area in succession, and because the training time was short, it was not yet possible to reach a salvo, so the sound was not uniform.

However, the howitzer fired loudly, accompanied by a whistling sound, and the four shells quickly reached their maximum speed at an initial velocity of 930 meters per second, and then fell one after another in the target area.

Halfway up the mountain ahead, there was a flash of fire and smoke, and the rocks on the mountain were blown apart, and the rocks flew in chaos.

The four howitzers fired four shells in succession over a period of fifteen seconds, after which the rate of fire dropped to eight to ten rounds per second, and the shelling ceased after firing more than 80 shells.

There are very few myopic eyes in this time and space, Liu Ru is eyesight is not bad, although the destructive power of this cannon is not too intuitive, but the momentum is too scary.

After Wang Yue threw the binoculars to Liu Ruyi, who was still stunned, he walked towards the howitzer truck, and at this time the artillerymen had already gotten off the gun truck and were waiting for his review.

"Hello Commander!" These are all veterans, and the salute is almost uniform.

The configuration of one artillery vehicle is four to five people, plus the logistics staff, and four self-propelled howitzers require only one platoon of soldiers.

"Brothers have worked hard!"

"Serve the starting point!"

Wang Yue took a closer look at the four self-propelled howitzers, which were also equipped like tanks with vehicle-mounted machine guns to protect against enemy approaches, as well as grenade launchers that could fire small grenades and smoke grenades.

"Yuanshan, continue to strengthen training, we will use this kind of cannon in a while." Wang Yue instructed Feng Yuanshan.

Feng Yuanshan already had a very intuitive understanding of the power of this howitzer, and he flicked his hands and said: "Does the commander mean the city of Gelansha in the south of Taiwan?" ”

The next goal of the Tiance Army is to clear the south of Taiwan from the Dutch and eliminate the potential threat of immigrants.

"That's right!" Wang Yue said.

Saying that Cao Cao Cao arrived, Zhuang Suwen, commander of the Nanyang Fleet, reported through the walkie-talkie, and the Dutch Governor in Taiwan, Putmans, visited.

Seeing the huge ships of the Tiance Army and Navy gathered at the mouth of the Tamsui River, Putmans's heart was extremely shocked, and after a close observation and comparison, he realized that the 1,000-ton Galen he was riding on was simply a small sampan compared to those big guys.

He was treated the same as the Spanish negotiators, and the boat had to stay at the mouth of the river, and he could only enter the Tamsui River on a naval surveillance warship.

Curiosity prompted him not to care about the other party's rudeness, and he was full of curiosity about this strange sailless automatic giant ship, Putmans, who could come aboard the ship and ask for it.

After boarding the sea surveillance battleship to take a closer look, Putmans's mood fell to the bottom of the glacier, an all-steel battleship! Why is it able to float on water? Everything on board is almost all iron!

Behind this phenomenon, it reflects the steel production of the Ming Dynasty and the technological level of the manufacturing industry, which has reached an unimaginably high level, which is a terrifying conclusion, and Putmans has a feeling of chilling to the bone.

What made him even more desperate was to come, for the Maritime Surveillance Battleship, though without sails, had reached an astonishing speed of twenty knots, whereas the Galen had a speed of only seven or eight knots at high speed.

Upon closer inspection, he found that the ships did not have a large number of cannons, which reassured him a little. But so what? Such a steel warship cannot be sunk by solid bullets, chain bullets, or scattered bullets, and it seems that after returning home, we will have to seriously study the tactics with those officers.

He was accompanied by Lieutenant Colonel Villa, who was also shocked by his naval background.

"Your Excellency the Governor......

As soon as Villa spoke, Putmans immediately stopped him with his eyes, although he didn't know if the soldiers of the Tiance Army who were watching them nearby could understand Dutch, so it was better to be careful.
