Doomsday Bunker Upgrade

While Chen Xin was preparing the excavation plan, the military also slowed down their offensive. They abandoned some of the caves and tunnels that had been punched down, instead holding on to areas that had been stabilized, and planned to blow them down. Many passages blocked all the roads for alien creatures to break through, leaving only part of the openings for their own use.

After such adjustments, the military only needs a small number of troops to hold a few main passages set aside, and it can block the passages for alien creatures to attack upwards.

And because of this shift from offensive to defensive adjustment, most of the troops that were originally intended to attack the ground were temporarily idle.

The military did not really let these troops sit idle. Apart from allowing them to continue to monitor the entire Dongting Lake area to prevent extraterrestrial creatures from digging new channels to rush out of the ground, it was to let these troops do for the next cleanup operations. get ready.

The military's offensive has not been very smooth before. On the one hand, it is related to weapons, and on the other hand, it is not suitable for operations in the underground tunnel environment.

For this reason, the military intends to conduct a training session for the existing troops during the three months of the start of the excavation work, and adjust the state and tactics of the troops so that they can perform better in the subsequent clearance operations. Its combat effectiveness is also more suitable for combat in underground caves and tunnels.

For this reason, the military specially reserved a small tunnel close to the ground surface without being completely sealed, and opened it up with the ground, and put idle troops into the tunnel in rotation, and battled with the combat sub-body in the tunnel for research. Tactics of 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 tactics.

By continuously putting various troops into the tunnels to fight, let them find more suitable tactics, and directly conduct actual combat tests. The military quickly figured out a set of suitable tactics and quickly promoted them. Arrived all the troops.

However, the military was not satisfied with this. On the one hand, they continued to allow the troops to explore tactics, while on the other hand they approached Chen Xin, hoping that he could provide some more practical equipment for underground operations.

Chen Xin had long anticipated the military's requirements. After all, the military put forward relevant requirements during the previous discussions on the offensive plan.

It was just that Chen Xin had no good ideas for the military's requirements.

Limited by the environment in the underground tunnel, all kinds of heavy vehicles can't go down at all, and at most some small vehicles such as Bobcat assault vehicles can pass.

And limited by the narrow and complex terrain in the underground tunnel, the heavy firepower of various artillery can not be used at all. After all, a shot can only hit more than 100 meters and it will blow up to the rock wall. When it collapses, the military will never use heavy weapons in this situation, no matter how hard it is.

Even the Titan's portable gun was abandoned, and only revolving machine guns were used instead.

However, even with revolving heavy machine guns, there is still the problem of ricocheting when bullets hit the rock wall.

This has had a great impact on the advancement and operations of the troops, and it has also made it really difficult for the military to achieve more eye-catching results in previous operations.

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

According to the military's request, Chen Xin could only think of tossing on the military's existing Bobcat assault vehicle, or designing new weapons for Titan.

The Bobcat assault vehicle is now a small multi-functional vehicle platform mainly equipped with the army. It has many advantages, such as light weight, small size, multiple functions, and strong adaptability. Before the disaster, the army developed a vehicle around the Bobcat assault vehicle The series of modifications have formed a car family.

Among these modifications, there is no shortage of 40mm assault guns and 120mm mortars, which can be called maddening modifications.

You know, the Bobcat assault vehicle is very compact. The length of the 6*6 body is only about three meters, and its own weight does not even have a ton.

However, even if the Bobcat assault vehicle can resist 120mm cannons, it cannot shoot effectively in underground tunnels. The military is not crazy enough to use guns of this caliber for tunnel warfare, so most of the time it is still going into battle. A model equipped with a heavy machine gun or a model with a small caliber artillery.

Even so, it still encountered many problems during use.

As a result, the military is eager to solve the problem of being unable to use powerful weapons in underground tunnels, and be able to put all kinds of heavy weapons into combat to achieve victory.

However, the most powerful weapons 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 280 square meters. In the narrow tunnel, it is often a shot. All hurt.

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 required by the military are all this virtue. The greater the power, the greater the damage area, and it is really not easy to use in the tunnel.

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 mechas. The logistic statistics concluded that the number of Titans and heavy mechas lost during the rework period of the military was more than the sum of the losses in the previous defense phase. More!

And more critical is the driver's loss. UU reading www. uukanshu.com

The heavy mechas in the tunnels are okay, at least they are not that big, and there is still room for dodge, but for the Titans, one can almost block a tunnel, only in some more spacious caves. The room for dodge, this undoubtedly allowed Titan to withstand a lot of attacks, and it also caused the driver's casualties to rise sharply.

Faced with such a situation, Chen Xin himself also eagerly hopes to be able to come up with heavy firepower that can be used in the environment of underground tunnels, so that the military can exert a stronger combat effectiveness in the next battle.

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

But this is not something that can be easily done. 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.

Holding his head in distress, he crumpled the draft paper filled with various ideas in front of him into a ball and threw it towards the corner. Chen Xin was caught in a predicament: "The road of live ammunition weapons is nowhere to go, can it be said? Should we consider non-live ammunition weapons?"
