Doomsday Bunker Upgrade Chapter 635: Easy to attack and defend

After the departure of the cargo ship, things in Europe are temporarily irrelevant to Chen Xin, and his daily work is now somewhat leisurely.

Although the alien attack in the Dongting Lake Theater is still raging, it seems a little weak in the face of the increasingly stable defense line and the industrial strength that has erupted with strong power after the adjustment of human beings.

To fight against steel with flesh and blood, if these alien creatures have a tide-like number, and at the same time have a not weak single-body combat power, I am afraid that they have already been wiped out in the war.

After all, this is just a group of alien creatures that are not very powerful, not Zerg or Tyron, and they don't have such exaggerated combat power.

Before it was affected by environmental factors, and the industrial production mode of human beings had not been adjusted, the alien creatures had an advantage.

Of course, if the alien creatures can break through the blockade of the Yan Kingdom's army and expand themselves, with their amazing reproduction ability, they will spread like a virus, and the number will increase exponentially.

If it really turned into such a situation, it would be difficult for the Yan Kingdom's army to deal with the alien creatures that were more than ants.

Fortunately, the Yan Kingdom's army blocked the expansion of alien creatures, and they were firmly confined to the Dongting Lake area, even if they planned to dig tunnels from the ground, in the face of various human monitoring methods and burrowing capabilities , still not enough to see.

Especially, the country of Yan has restored the connection with the satellites in the sky. With the monitoring and guidance of satellites, the military strike force of human beings has also returned to normal levels. A large number of over-the-horizon weapons have made these people who are still fighting physically. The guy knows what steel tracks are rolling forward.

Although humans are not aliens crushed by tank tracks, there is no doubt that these aliens were crushed by steel creations.

In fact, after the restoration of satellite communication and military satellite functions, the situation of war with alien creatures has changed.

Before, due to the obstruction of dust clouds, satellite guidance in the missile guidance method has undoubtedly become unusable, so the military can only rely on the laser guidance and limited radar guidance of front-line combatants, as well as the inertial guidance of the missile itself Using these limited means to use missiles, the accuracy and efficiency of attacking alien creatures can only be regarded as unsatisfactory.

It is impossible to deeply control the battlefield situation, and the missiles do not know where to hit to effectively stop the offensive of alien creatures. This leads to the fact that although the military has a big killer, it can only detect in the air and the ground observation distance range. For internal use, it cannot achieve over-the-horizon strikes, nor can it achieve overall control of the battlefield.

It doesn't mean that missiles can't be used without satellite navigation. As long as there are coordinates, these big killers can be launched by inertial guidance.

But without the battlefield information, it is difficult to choose where these missiles should be directed.

The price of a missile is high, and it would be too wasteful to bombard cannon fodder on the battlefield that alien creatures don't even care about themselves.

And now, satellite monitoring is enough to allow humans to grasp every move of alien creatures on the battlefield, and no details and changes can escape the eyes of the sky.

The re-launched satellite navigation system has also played a role again. As long as the satellite finds any bad tendency of the alien creatures on the ground, the missile will hit the target under the precise positioning of the satellite navigation.

It is with the cooperation of the satellites that after the human beings regained contact with the satellites, the military has used a wave of missiles to wash the ground and knocked out all the underground passage exits that the alien creatures can attack in the Dongting Lake area. Reduced the ability of alien creatures to deliver cannon fodder to the battlefield.

This reduces the total number of alien creatures on the battlefield to a considerable extent, and also effectively curbs the reinforcement of the underground alien creatures to the battlefield.

Although alien creatures can continue to dig new channels and send new reinforcements to the battlefield, under the attack of missiles with precise satellite positioning and navigation, such reinforcements cannot play a good role.

During this period of time, it is not that alien creatures have not tried to dig along the groundwater layer and infiltrate the defense line to attack as before, but human beings' grasp of the hydrology and geological conditions of this area allows them to effectively Analyze the possible attack directions of alien creatures.

In addition to the vibration monitoring system and the seismic network originally used to predict earthquakes, the movements of alien creatures underground are monitored by humans.

As long as the vibration monitoring shows that there are signs of dangerous escalation and alien invasion in a certain area, the land fleet, which has been swimming around the battlefield, will arrive in the area and carry out a powerful force to directly destroy the aliens. Any possibility of creatures breaking out of the ground.

Relying on the powerful air strike capability of the landing aircraft carrier and the battlefield maneuverability of the land-based ship, the entire fleet is active on the battlefield like a moving fortress.

Destroyers and frigates are active on the battlefield, providing fire support for the battlefield as a mobile force, and when necessary, they can penetrate deep into the enemy's rear from the air, while land-based aircraft carriers spend most of their time patrolling the battlefield according to the military's planned route of action , providing air strike power and intelligence support.

Where there are signs of alien gatherings, fleets will drive, using missiles and aerial bombs to make aliens fully aware of the absolute gap between flesh and blood and steel and fire.

Aliens are of course not the ones who are passively beaten. They have also made many attempts during this period, such as sending out the giant fire-breathing progeny that once almost caused great trouble for the defense line to dig out of the ground again, and then cooperate with a large number of fighters. Body attack defense line~IndoMTL.com~ But this tactic is really simple and rough for human beings.

Let's not talk about the missile attack system that has been deployed around the battlefield, just the frigates in the land fleet roaming the battlefield can directly use naval guns to kill this thing.

Compared to the carpet bombing with large-caliber artillery from outside the line of sight, the frigate can fly to the vicinity of the giant pyrotechnic body and use the naval guns to smash the head of the giant pyrotechnic body by direct fire within the line of sight. .

Of course, in the vast majority of cases, land-based ships do not do this, but instead use satellite monitoring and reconnaissance aircraft positioning, and then use missiles to kill this thing.

Only when these big guys are too close to the line of defense, will the land-based ships approach by flying in the air and shoot directly with naval guns.

Relying on this series of methods, alien creatures are no longer a huge threat to Yan Guo, but have become a controllable situation.

With the decline in the number of soldiers killed in the line of defense, the military even has the idea of ​​turning this place into a round battle, turning the alien creatures into a whetstone for sharpening its own army.
