According to the predetermined plan, the Xian army will dispatch 54 pickup trucks, each of which will be loaded with a 12-barrel rocket launcher, to carry out suppressive strikes on the enemy's front line and targets at exposed firing points.

After the battle, they left without giving the enemy's hidden artillery time to lock in the counterattack, providing artillery cover for the smooth takeover of the position, and at the same time dampening the sharpness of the armpits.

At six o'clock, 54 pickup trucks left the convoy and headed for the north of Liangxian, 10 miles behind the coalition position, at intervals of 30 paces from east to west, forming a long snake formation and carrying out the first salvo strike at the armpit position.

Hundreds of rockets roared like a roar, dragging their tail flames and rushing towards the enemy formation, setting off a series of earth-shattering fury that resounded through the sky, killing the armpit ghosts and wolves, howling and wailing, and somehow falling into a sea of bullets and fire in an instant.

The Liang Jun Yuke on the battlefield let out a loud shout:

"Our cannons, our cannons!"

"God, it must be our reinforcements ......"

At the end of the salvo, the 54 pickup trucks flew away, until more than 10 minutes later, a burst of artillery fire came from more than 20 miles away, hitting the front and rear of the previous 54 pickup trucks, and the accuracy was not very high.

At this time, Bai Liyan stood on the watchtower in Liangxian and said to Jiang Jie beside him:

"Let people calculate the location of the enemy's heavy artillery fire as soon as possible, and estimate the number of enemy artillery."

"No. However, with such a salvo of our troops, the armpit dwarves may divert the artillery positions. ”

"It's possible. But don't forget, our rocket artillery is a mobile battle, which can be near or far within 15 miles, and their large-caliber artillery is very heavy, relying on horses and manpower to pull it, and it takes a lot of time to transfer and deploy.

At the same time, if you want to destroy our mobile artillery, you can't go back. If it retreats, our army's front line will be much safer, and it will be extremely beneficial to our army to push forward smoothly. ”

Although it is not ruled out that the armpit long-range artillery may transfer their positions to temporarily ensure safety, it will also create a gap in the enemy's firepower vacuum for the Xian army.

If the enemy is fully aware that he will face a stronger opponent, he will not choose to withdraw all his heavy artillery positions in the short term, but will leave some as bait to test the density and power of the Xian army's firepower. If all of them are withdrawn, the Xian army will immediately launch a counterattack to recapture the lost positions on the front line.

These truths are not only clear to Bai Liyan, Jiang Jie and others, but also extremely clear to the extremely intelligent armpit dwarves. Bai Liyan's volley is to tell the commander on the opposite side that he is facing a stronger opponent, and if he slacks off, he will be devastated. Only in this way can we provide conditions for the development of the tactics of the Xian army.

The enemy's artillery fire lasted sixteen or seventeen minutes, and it is not difficult to see from the speed of reaction and accuracy that the axillary calculation speed is much faster than that of humans.

Modern artillery has ballistic radar and ballistic calculation computer, which uses the principle of ballistics and parabola to calculate the location of enemy artillery by using the speed, altitude and landing point of the projectile.

If there is no ballistic radar and a computer, it can only be calculated by the artillery crew, using manual reverse solving.

This first requires the artillery observer to estimate the height of the enemy's projectile, judge the starting point of the shelling and the focus of the projectile, determine the approximate distance, and it must be the height of two points of the same trajectory, so that through the principle of plane triangle and parabola, the position of the enemy's artillery is calculated manually in reverse, and finally the accuracy is verified by substituting the bomb landing point.

If you don't consider the accuracy of the estimate, it takes 10 minutes from the beginning of the estimate to the calculation result. It only took about three or four minutes for the axillary man, which shows how high his calculation speed and estimation ability are.

After the salvo, the Xian army successively entered the position to take over the battle line, and the city began to lay field telephones to the battlefield to facilitate the coordination of command and order.

Liang Guo's phone was only spread to Jinye and Boyuan, Yongping did not access the phone, and Liang County did not, Xiao Gongyi's call had to go to Jinye, although it was very inconvenient, but it was more than a hundred times better than ten years ago when someone sent someone to send a letter for a month.

On the night of entering Yongping, Bailiyan immediately chose a place to install an internal combustion engine generator set to supply power to the front line, otherwise it would be too late to rebuild the power grid facilities of Liangguo.

At the same time that the Xian army entered the position, the offensive of the armpit people did not stop, but under the previous bombardment, it was dizzy and suffered many casualties, and the intensity of its attack was significantly weakened.

The Xian army took advantage of this gap to set up machine gun and 654 mountain artillery positions, and mortars arranged the second line of trenches.

Previously, the grenade launcher occupied a separate formation, but after the First World War in Hukou Bay, it was found that the tactical establishment was not practical, and it was later changed to be carried by soldiers and used as a squad support firepower, and did not occupy the establishment. The grenade launcher uses 45 milli caliber ammunition, and after the improvement of the 80 milli mortar projectile, the firing has increased significantly.

The single-base propellant used in the past was packed with powder compaction, but after the improvement, the double-base gunpowder was used to be granulated, so that there was air in the cartridge and the gunpowder burned more fully.

Not long after the Xian army entered the position, they were attacked by the armpit medium-caliber artillery, and two hundred paces away from the front was the armpit position, and they hid in the trenches day and night to dig into the earth, and the distance of two hundred paces did not take three days to penetrate, and when the distance was one hundred and twenty or thirty paces, their grenadiers began to throw grenades that needed to be ignited.

Different from the previous black powder grenades, the axillary now uses bombs mixed with ammonium nitrate explosives, and the power has increased significantly, but it is still only mixed in small amounts, and not all of them are filled with ammonium nitrate, which shows that they have indeed not yet realized the industrial production of "ammonia" in the chemical process.

But this time, Bailiyan would not give them a chance to penetrate the trenches, and as soon as the Xian army took over the position, they immediately suppressed the fire with mortars and grenade launchers in turn, and the armpit people were caught off guard again.

Although the Yuke is equipped with artillery and grenades, there are no mortars, and the grenade launchers are only equipped with a small number of them, most of which are used to launch flares.

"If this cannon had been used earlier, our army would not have suffered such huge casualties, these monsters are really hateful."

At this time, Bailiyan put down the telescope and said:

"Although this cannon is good, if it is seized and imitated by the armpit people, it will undoubtedly be a huge threat to our Central Plains, so I have not dared to sell it in large quantities."

Grenade launchers and mortars are important support weapons to fill the close range of infantry, and they are valuable military experiences summed up by the earthlings in half a century of warfare.

Based on this tactical concept, Bailiyan is beneficial to the Xian army, but if it is captured by the armpits in the war, they will also imitate it, and even improve it for use in the war, which will pose a great threat to mankind, because they are more physically strong, but they can be equipped with super-large caliber mortars.

Although artillery materials and propellants may not be able to be imitated, and it takes a period to develop and produce, it is entirely possible to reduce the firing range, or increase the caliber and amount of black powder, and with their physical fitness, it is entirely possible to achieve the best effect of the Xianjun mortars and grenade launchers.

The series of victories in the wars that have been won before this have been largely based on the enemy's serious miscalculation of humanity and underestimation of the enemy. But from today onwards, the war will be even more brutal, and every victory will require huge sacrifices and costs.

Under the intensive bombardment of the Xian army, the armpit men immediately stopped the excavation operation, turned to the bunker fortifications to conceal, and did not make any substantial advance all morning. However, the continuous fire coverage of the positions of the Xian army and the crossfire with heavy machine guns were nothing but futile attempts.

It has been more than three years since the battle, and the deification of the armpit people is constantly shattering, and their immortal bodies, cold weapons under the gunpowder age, and even the Stone Age, are indeed invincible.

Once the era entered the industrialization, the development of gunpowder and gun and bullet technology, this immortal golden bell door was not said to be gone, but at least greatly weakened, coupled with their slow fertility rate, five human beings in exchange for one of them is enough to balance their casualties and birth rate.

Moreover, Bailiyan also found that under the same equipment conditions, field warfare and positional warfare were not suitable for them.

Their two eyes are located under their left and right armpits, which means that most of their weapons are aimed and fired under their armpits, so they cannot crawl.

Once they use the lying position, their eyes will be pressed to the ground, and the infrared vision of the forehead only has infrared observation and feature construction, and there is no clear visual sense, which is not conducive to their aiming and shooting.

Since their eyes were under the armpits, they would expose their chests and their entire heads above the trenches when fighting in the trenches, so they needed to wear thicker helmets and build partitioned earthen stacks to cover their heads and faces above the chest, exposing only the eyes under the armpits of the side shoulders.

In order to facilitate the advance of field battles, most of them will form formations during the breech gun period, taking advantage of their physical strength, using steel shields as thick as seven or eight millimeters to resist the attack of cold weapons head-on, and assisting mobile squads to carry out tactical breakthroughs between each formation.

After the advent of fixed weapons, although the effect of this tactic was greatly reduced, it began to use trench excavation tactics in large quantities to avoid large-scale defenseless field battles, and instead used trench excavation to attack and break the defense system.

Although there are many physiological constraints on axillary people, there are many ways to deal with humans.

Previously, the royal guest tried to launch a counterattack in a prostrate position, but he did not expect that the armpit people scattered a large number of "thumbtacks" on the ground, because they could not fight on their stomachs, but humans could, so they threw thumbtacks.

Moreover, they have steel plates in their shoes, and the beastmen also wear steel boots, so even if they are stabbed by their own pushpins, they can heal quickly, which makes it extremely difficult for humans to fight.

Soon after the Liang army and Yuke withdrew from their positions, the exhausted Yuke and Liang soldiers were relieved. For them, the nightmare is almost over.

At four o'clock in the afternoon, the Northeast Black Crow Forest called, and the frontal enemy had moved.

"The Black Raven Forest has always been the weak link on the right flank of our army before, and it is not surprising that the armpit people launched a surprise attack from this."

Imperial Governor Peng Zhi said quickly, Bai Liyan looked at the location of the black crow forest on the map and asked:

"How did the Armpit people launch their raids in the Raven Forest?"

"The assault would be preceded by a burst of long-range artillery, followed by a surprise attack with the help of trees as cover and small-caliber artillery as support. Due to the thick trees in the forest, it is not conducive to the raids of the berserkers, so very few orcs are engaged in battle. ”

After listening to what Peng Zhi said, Bai Liyan picked up the phone after a little thought and connected to Mo Yunfeng's headquarters:

"General Mo, adjust the speed and adjust a heavy machine gun squad and a mountain artillery squadron, rush to the rear of our army's defense line in the Black Crow Forest to stand by, and after the enemy artillery is over, the infantry will attack, and immediately go forward to return fire. Remember, pay attention to the covert march. ”

"No!"

Hanging up Mo Yunfeng's phone, Bailiyan called Jiang Jie:

"I'm Bailiyan, there is a counterattack on the enemy in the direction of the Black Crow Forest, and you are in a position to closely monitor the enemy in front, and you flank Gaohu Village."

"The last will understand." I want to chat about "Empire Travel" with more like-minded people, pay attention to "excellent reading literature" on WeChat, talk about life, and find confidants~
