While Chen Xin was preparing the excavation plan, the military also slowed down its offensive. They abandoned some caves and tunnels that had been dug down, and instead defended the areas that had been stabilized, and bombed them in a planned way. Many passages have blocked the way for alien creatures to break through, leaving only some holes for their own use.
After such adjustments, the military only needs a small number of troops to guard a few main channels that have been left open to block the upward attack of alien creatures.
And because of this adjustment from offense to defense, most of the troops originally prepared to attack the underground were temporarily idle.
The military did not really let these troops idle. In addition to letting them continue to monitor the entire Dongting Lake area to prevent alien creatures from digging new channels and rushing out of the ground again, they also let these troops prepare for the next clearing operation. get ready.
The military¡¯s previous offensive has not been very smooth. On the one hand, it is related to the weapons, and on the other hand, it is also because it is not adapted to fighting in the underground tunnel environment.
For this reason, the military plans to conduct a comprehensive training of the existing troops during the three months of excavation work, and adjust the status and tactics of the troops so that they can perform stronger in the subsequent clearing operations. The combat effectiveness is also more suitable for fighting in underground caves and tunnels.
For this reason, the military specially reserved a small section of tunnels close to the surface that was not completely sealed, and opened it up to the ground. It rotated idle troops into the tunnels and fought with the combat sub-units in the tunnels to study Tactics for fighting in tunnels and caves.
Because it is a specially reserved tunnel, the number of alien creatures in the tunnel is not as exaggerated as in other tunnels, and the military also has more room for trial and error and research on tactics.
By continuously putting various troops into the tunnels to fight, allowing them to find out more suitable tactics, and directly conducting actual combat tests, the military quickly found out a set of applicable tactics, and quickly promoted them All troops arrived.
However, the military was not satisfied with this. On the one hand, they continued to let the troops explore tactics, and on the other hand, they approached Chen Xin, hoping that he could provide some more practical equipment for underground combat.
Chen Xin had already expected the military's request. After all, the military had made relevant requirements when discussing attack plans several times before.
But Chen Xin didn¡¯t have any good ideas regarding the military¡¯s requirements.
Due to the environment in the underground tunnel, various heavy vehicles cannot go down at all, and at most they can pass through some small vehicles such as the Lynx assault vehicle.
Moreover, due to the narrow and complex terrain in the underground tunnel, heavy firepower such as various artillery cannot be used at all. After all, a cannon can only be fired more than a hundred meters before it hits the stone wall. If it is too powerful, it may even cause damage to the tunnel. Collapse, no matter how stubborn the military is, they will not use heavy weapons in this situation.
Even the Titan's portable cannon was abandoned in favor of using only the minigun.
However, even with a rotating barrel heavy machine gun, there is still a problem of bullets ricocheting when they hit the rock wall.
This has had a great impact on the advancement and operations of the troops, and it has also made it difficult for the military to achieve more eye-catching results in previous operations.
And this also puts great restrictions on Chen Xin's conception of new weapons.
According to the requirements put forward by the military, the only thing Chen Xin can think of is to work on the military's existing small platform such as the Lynx assault vehicle, or to design new weapons for Titan.
As a small multi-functional vehicle platform currently mainly equipped by the military, the Bobcat assault vehicle has many advantages such as light weight, small size, multiple functions, and strong adaptability. The Army developed a series of products around the Bobcat assault vehicle before the disaster. A series of modifications form a car family.
Among these modifications, there are many such crazy modifications as the 40mm assault gun and the 120mm mortar.
You must know that the Bobcat assault vehicle is very small in size. The 6*6 body of the vehicle is only about three meters in length and its dead weight is not even one ton.
However, even if the Lynx assault vehicle can withstand a 120mm caliber cannon, it cannot fire effectively in an underground tunnel environment. The military is not crazy enough to use artillery of this caliber for tunnel warfare, so most of the time it is still used in battles. Models equipped with heavy machine guns or small-caliber artillery.
Even so, we still encountered many problems during use.
This has led to the military¡¯s urgent hope to solve the problem of being unable to use powerful weapons in underground tunnels, and to be able to put various heavy weapons into combat to achieve victory.
However, powerful weapons are all big explosions. In order to pursue the killing effect 85.The 3-meter grenade can produce about 900 effective fragments and can kill enemies within 280 square meters. In narrow tunnels, it can often be hit with one shot, injuring both the enemy and ourselves.
This also led to the fact that even though Chen Xin had a system, he really didn't think of any good ideas.
After all, the powerful weapons that the military wants have this kind of virtue. The greater the power, the greater the damage area. It is really difficult to use it in tunnels.
In the past, the military mainly relied on heavy mechas and Titans to clear the way, and achieved certain results.
But this also caused terrible losses to Titans and heavy mechas. Logistics statistics concluded that the number of Titans and heavy mechas lost during the military's rework period was greater than the total losses in the previous defense stages. More!
And more importantly, the loss of the driver.
The heavy-duty mechas in the tunnels are okay, at least they are not that big, and there is still room to move and dodge. But for Titan, one can almost block a tunnel. It is only found in some spacious caves. There was no room for dodge, which undoubtedly allowed the Titan to withstand a lot of attacks, and also caused the driver's casualties to skyrocket.
Faced with this situation, Chen Xin himself is eager to come up with heavy firepower that can be used in environments such as underground tunnels, so that the military can exert more powerful combat effectiveness in the next battle.
After all, even if the excavation method is used to carry out subsequent operations, the military will still have to go deep into underground tunnels to conduct operations. Without the investment of new weapons, it may be difficult to reduce casualties and equipment losses by relying solely on tactical changes. loss.
But this is not something that can be done easily. Even if Chen Xin can save a lot of research and development time, he has no clues and inspiration at this time and cannot figure out how to solve this problem.
Scratching his head in distress, he crumpled up the draft paper filled with various ideas in front of his eyes and threw it to the corner. Chen Xin was trapped in a dilemma: "The road to live ammunition weapons is dead, is it possible? Should we consider non-live ammunition weapons?¡±
