Doomsday Bunker Upgrade Chapter 698: The problem of the military

While Chen Xin was preparing the excavation plan, the military also slowed down its offensive. They abandoned some of the caves and tunnels that had already been drilled, and instead stuck to the areas that had been stabilized, and planned The explosion collapsed many passages, blocking all the paths for the alien creatures to break through, leaving only part of the holes for their own use.

After such adjustments, the military only needs a small number of troops to hold a few main passages left to block the passage of alien creatures' upward attack.

And because of this shift from offense to defense, most of the troops that were originally going to attack the underground were temporarily idle.

The military didn't really let these troops idle, except to let them continue to monitor the entire Dongting Lake area to prevent alien creatures from digging new passages and rushing out of the ground again, it was to let these troops prepare for the next Getting ready for the siege.

Previously, the military's offensive has not been very smooth. On the one hand, it is the relationship between weapons, and on the other hand, it is also because it is not suitable for operations in the underground tunnel environment.

It is also for this reason that the military intends to retrain the existing troops during the three months of the excavation work, and adjust the state and tactics of the troops so that they can play a role in the subsequent clearing and suppression operations. It has stronger combat power and is also more suitable for combat in underground caves and tunnels.

For this reason, the military specially reserved a small tunnel close to the surface without completely sealing it, and opened it up with the ground, and put the idle troops into the tunnel in rotation to engage with the combat sub-units in the tunnel. , 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 other tunnels, and the military also has more room for trial and error and tactical research.

By constantly putting various troops into the tunnels to fight, allowing them to explore more applicable tactics and directly test the way of actual combat, the military quickly discovered a set of applicable tactics, and It was soon rolled out to all troops.

However, the military was not satisfied with this. On the one hand, they continued to let the troops conduct tactical exploration, and on the other hand, they approached Chen Xin, hoping that he could provide some more practical equipment for underground operations.

Chen Xin had already anticipated the request made by the military. After all, the military made relevant requests when discussing the offensive plan several times before.

Only for the request made by the military, Chen Xin did not have any good ideas.

Restricted by the environment in the underground tunnel, various heavy vehicles cannot go down at all, and at most some small vehicles such as Lynx assault vehicles can pass.

In addition, due to the narrow and complex terrain in the underground tunnels, heavy firepower such as various artillery can not be used at all. After all, one cannon can only be shot more than 100 meters away, and it will explode to the stone wall. It will cause the tunnel to collapse, and the military will never use heavy weapons in this situation.

Even the Titan's handguns were abandoned in favor of only rotary machine guns.

However, even if it is a revolving machine gun, there is still the problem of ricocheting when the bullet hits 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 relatively dazzling results in previous operations.

And this also makes Chen Xin have a lot of restrictions on the concept of new weapons.

According to the requirements of the military, Chen Xin can only think of tossing on a small platform such as the military's existing Lynx assault vehicle, or designing new weapons for the Titan.

The Lynx assault vehicle is a small multi-purpose vehicle platform mainly equipped by the army. It has many advantages such as light weight, small size, multiple functions and strong adaptability. The army developed around the Lynx assault vehicle before the disaster. A series of modifications have been made to form a car family.

Among these modifications, there is no lack of 40mm assault guns and 120mm mortar howitzers that can be called crazy modifications.

You must know that the Bobcat assault vehicle is very small in size. The length of the 6*6 body is only about three meters, and the self-weight is not even a ton.

However, even if the Lynx assault vehicle can resist a 120mm caliber cannon, it cannot shoot effectively in an underground tunnel environment. The military is not crazy enough to use this caliber artillery for tunnel warfare, so most of the time it invests in The ones that fought were still models equipped with heavy machine guns or models with small-caliber artillery.

Even so, there are still many problems encountered during use.

This has also led to the urgent hope of the military to solve the problem of being unable to use high-power weapons in underground tunnels, and to be able to put various heavy weapons into battle to gain victory.

However, weapons with high power are big bombs. In order to pursue the killing effect, the 85mm grenade can produce about 900 effective fragments, which can kill the enemy within a range of 280 square meters. In narrow tunnels, it is often one shot. In the past, both the enemy and me were wounded.

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 are all of this kind of virtue.

In the past, the military mainly relied on heavy mechas and Titans to open the way, and achieved certain results.

But this also caused terrible losses to Titans and Heavy Mechs. Logistic statistics concluded that the number of Titans and Heavy Mechs lost during the military's rework period was more than the loss in the previous defense phase. It adds up to more!

And more importantly, the loss of the driver~IndoMTL.com~ The heavy-duty mecha in the tunnel is not bad, at least it is not that big, and there is still room to maneuver and dodge, but for the Titan, one is almost To be able to block a tunnel, there is only room for dodge in some spacious caves, which undoubtedly made Titan endure a lot of attacks, and also caused the driver's casualties to skyrocket.

Faced with such a situation, Chen Xin himself is eager to come up with the heavy firepower that can be used in the environment of underground tunnels, so that the military can exert more powerful combat effectiveness in the next battle.

After all, even if excavation is used to carry out subsequent operations, the military still has to go deep into the underground tunnels to fight. If there is no investment in new weapons, it may be difficult to reduce casualties by only relying on tactical changes. and loss of equipment.

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 clue or inspiration at this time, and can't think of how to solve this problem.

Grabbing his head in distress, he crumpled the scrap paper covered with various ideas in front of him into a ball and threw it to the corner. Chen Xin was completely in trouble: "The road to live ammunition will not work. , do you want to consider non-live ammunition weapons?"
