As for the use of rocket artillery in the field, the power is indeed amazing. If a one-two-two rocket launcher hits the marching brigade, it can directly send a squadron of Japanese troops around the explosion point to the western sky. But if it is used against these permanent fortifications, it is far less powerful than the barreled artillery. Of course, there is still power for field fortifications.

But against this combination of light and dark bunker groups, it has almost no effect. The unit once disassembled the lightweight 107 rocket launcher and used the tactic of firing a single barrel to strike at the firing holes of the permanent fortifications at a distance beyond the range of Japanese machine-gun fire. However, it was because of the poor accuracy of long-range shooting, and the effect was not good.

However, the close-range shooting was almost impossible to carry out under the interference of the mountain artillery, mortars, and infantry artillery in the rear of the Japanese army. Moreover, the fire of the rocket artillery was too large, and even if it could accurately hit the target, the losses were not light under the retaliation of the artillery fire of the Japanese army, which reacted very quickly.

In fact, the reason for the poor single-barrel firing effect of the 107 rocket launcher is that the troops are not too flexible in this regard. When this kind of 107 rocket artillery was first distributed to the troops, it was taken into account that this kind of rocket artillery was mainly used as a fire cover in the field army, and that it was not easy for the field troops to keep secrets.

Only let the troops learn to disassemble the 12-barrel rocket launcher as a single-barrel rocket launcher when necessary, and use it with the advance of the combat troops, but did not let the troops learn this simple way of firing rocket artillery. Yang Zhen didn't want this kind of rocket artillery to be captured by the Japanese army one day, and after learning this method, the Japanese army sent people to carry a rocket that could be carried by one person and disassembled into a single tube, or even a simple rocket, to sneak attack a certain level of command organ.

In later generations, there were almost no regular combat units except for special forces and those terrorists. However, the AK rifle, which is called the type of rocket artillery, is extremely flexible in dismantling and firing, and it is still quite powerful when used as a high-power weapon for close-range sneak attacks.

During Vietnam's anti-US period, the Vietnamese army's special forces used 107 rocket launchers, which were broken into single or double tubes, to secretly infiltrate the vicinity of US military airfields, and fired more than 200 rockets in one go in a short period of time. And when these troops penetrated within sufficient range, the U.S. military did not notice any movement.

In the Middle East, there is also a certain country in Central Asia, and this kind of decomposition and carrying is extremely convenient. It can be used in groups or individually when necessary. Even the rocket launchers and rockets that can be used even if the back cover of the rocket is smashed and ignited with a torch are often used as a weapon for medium- and long-range sneak attacks by the resistance movement that the Americans call terrorists.

Although this weapon is not very powerful, the accuracy of the salvo is not very high. But the advantage is that it is lightweight, and extremely flexible to assemble and use. Although the shells are a little more expensive, they are very suitable for the use of the Anti-United Nations in terms of quality, and the firing range is not worse than that of the mountain artillery equipped by the Japanese army, but the firepower density is far superior. That's why the equipment was given to the division level as a fire blocking weapon.

However, after all, the regular troops are not engaged in guerrilla warfare, and it is better to use regular combat methods. Since it has been assigned to the unit as a division, it is often assigned to the regimental level during combat. Then no one can guarantee that this weapon will not be captured by the Japanese army, let alone that the artillery will not be captured by the Japanese army.

According to the Japanese army's learning ability and national strength, if they want, they can produce more similar weapons. Yang Zhen didn't want his troops to be disgraced by this kind of weapon he "designed". Therefore, many methods of use, Yang Zhen did not issue to the troops.

If the special reconnaissance brigade of the military region were here, I am afraid that the effect would be very different. Pile up a mound of dirt to make a super simple launcher, and then set rockets on top of this mound. Use the improvised sight and aim the rocket. Using two dry batteries and a few sections of wire as launchers to run away, even if the Japanese artillery on the opposite side reacts quickly, I am afraid it will not have much effect.

If Chen Hanzhang's troops had used this firing method to aim at the fire embarrasses of the Japanese main fort within 500 meters, the progress would have been much faster and the results would have been much more obvious. Two men with two dry batteries, a few wires, and a rocket are much smaller than a target with a launch tube. As for the lightness, there is no way to compare the two.

Of course, if you are not afraid of making a big fuss, it is not impossible to smash the back cover of the rocket and launch it directly with a torch. It's just that this launch method is relatively dynamic, and it is easy to expose the target in advance. No one is stupid, and it would be stupid if you couldn't find out where your big torch was. It's just a pity that this lightest method of launching, except for the special reconnaissance brigade of the military district, not a single unit will use it.

In the case that the artillery power is not enough to completely destroy the so-called core fortifications, these permanent fortifications can only be blasted with high-yield explosives under the cover of tanks and flat-firing anti-aircraft machine guns. The lack of equipment preparation also caused considerable difficulties and delays in the course of the battle.

It is also important to mention that the Japanese have an almost innate specialty in building fortifications. Although many of these fortifications were hastily modified, a lot of thought was still put into their design and construction. All the fortifications are interconnected, and the firing range is not only quite open, but also the firing points are all composed of light and dark.

A large number of bunkers and bunkers were built around each main fort, forming a complete crossfire configuration with the main fort. Around the largest one main fort, as many as twenty-eight light and dark bunkers and machine-gun fortifications were constructed. Between the main fort and the bunker, a large number of mines were laid. And in depth, a large number of mortars and infantry guns are also deployed.

The crossfire between these bunkers and the main forts, which are deployed in a plum blossom shape around the main forts, can be fired at 360 degrees without dead angles. At the same time, a large number of half-man deep trenches were dug around the various fortifications of the Japanese army to facilitate the rapid movement of troops. Considerable minefields were laid to fill the gaps in the defenses.

And when digging a trench, whether it is an anti-tank trench or a communication trench or a trench, all the earth is piled up on the outside side of the trench. The soil is covered with anti-infantry mines and a small number of anti-tank mines. If the infantry wants to use the earth, you must first clear the mines under the enemy's heavy fire.

If you want to use your tank's cross-country ability to crush these anti-infantry mines, you need to be careful not only of the mixed anti-tank mines. Also beware that when the tank is climbing the slope, the chassis with the worst defense capability above and below the body is exposed, giving the Japanese army the opportunity to sneak attack the Taisho 11 infantry anti-aircraft guns deployed on the other side of these trenches.

In frontal combat, this Taisho 11-year 37-mm infantry flat-firing gun would not be able to penetrate the improved frontal armor of the tank even within 50 meters. But if you hit the part, in the chassis the result is different. When capturing Bayantara, the Japanese army adopted this tactic and destroyed an entire tank platoon under Chen Hanzhang's command.

At the same time, the number of machine guns deployed on various positions of the Japanese army far exceeded the original establishment of the Japanese army. In the words of Liu Yanlai, Chen Hanzhang's chief of staff, he has fought with devils for so many years, and it is the first time he has seen devils deploy so many machine guns in a certain unit within the unit area. It was the first time I had seen the Japanese army lay so many mines in a certain battle.

Landmines are a common means used by the Anti-Japanese Union in defensive warfare, and in previous operations, many Japanese troops have been killed and wounded. However, the Japanese army, which had always paid little attention to defensive warfare, rarely used mines in defensive operations. Even if there were, there were never so many mines per unit of time and per unit area.

In fact, it was not the Japanese machine guns that really brought difficulties to Chen Hanzhang's attack, let alone those anti-infantry mines, mortars and grenadiers. These machine guns can't penetrate the improved tank armor of the Anti-Union, and those anti-infantry mines are indeed a great threat to the infantry, but the threat to the tank is also negligible.

What really threatened the speed of his advance was the artillery deployed by the Japanese in depth, as well as those anti-tank mines. The biggest threat was the large number of anti-tank trenches dug by the European and Japanese forces, as well as the infantry anti-tank guns on the other side of the trenches.

Without the threat of these anti-tank mines and trenches, his tanks could have sent infantry directly to the Japanese pillboxes. The 45-mm guns on the tanks were useless against the main forts, but they had no problem against the rest of the ordinary fortifications.

However, the large number of anti-tank trenches dug by the Japanese army in the interior of their own positions, the large number of anti-tank mines laid out, and the extremely light Sanqi flat-fire guns that were fired at close range and transferred greatly limited the use of tanks. even brought a lot of losses to the armored troops under Chen Hanzhang.

No one would think that the three-meter-wide, well-connected trenches in the Japanese positions were just communication trenches. With such a wide communication trench, the artillerymen could hit the shells into it even with their eyes closed. If these trenches were mere communication trenches, I am afraid that they would have sent the troops to death rather than fighting. Anyone who is not too idiot will understand what these trenches with a width of more than three meters are for.

It's just that I'm afraid that even those who invented anti-tank trenches in the first place would not have thought that the Japanese army had also built a large number of anti-tank trenches between the first, second and third line positions. However, the anti-tank trenches in the deep defensive circle of the Japanese army were obviously hastily built on the basis of the original trenches and communication trenches.

Because even in the depths of the anti-tank trenches, no one will connect them with all kinds of permanent and semi-permanent fortifications. No one will be in the middle of the anti-tank trench, and there will be a bunker group. The anti-tank trenches on the periphery of the Japanese army were clearly built originally. As for the depth, I am afraid that the first line of the Songhua River has been broken through, and I learned that the Anti-Japanese Federation has a large number of tanks, which were temporarily repaired.

Although these anti-tank trenches in depth were temporarily repaired, they were interspersed with bunker groups and fortifications. However, it is precisely the temporary repair of anti-tank trenches that are not like anti-tank trenches, trenches are not trenches, and communication trenches are not like things, coupled with a large number of anti-tank mines, but they have become the main means of preventing the rapid assault of Chen Hanzhang's tank by the 14th Division of the Japanese Army.

This tactic adopted by the Japanese army was the first time in all the previous operations between the Anti-Japanese Union and the Kwantung Army. There are many hidden bunkers, but it is the first time that the Japanese army has used such a dense anti-tank trench and various mines at the same time. In particular, anti-tank mines were used by the Japanese army for the first time. The short-term failure to adapt to the new tactics and tactics of the Japanese army was also an important reason for Chen Hanzhang's slow attack.
