Doomsday Bunker Upgrade

Three months passed quickly.

The excavation work went very smoothly. More than 90% of a deep underground tunnel has been completed, and only a short distance is left to open up the underground nests of alien creatures.

The military is also preparing vigorously. The newly installed laser assault vehicle has been equipped with the team that will be the vanguard of the offensive. In these three months, a set of methods of use have been explored and used for it. Developed relevant tactics.

Although this laser assault vehicle is only equivalent to a heavy machine gun in power, after being put into use, the military concluded that laser weapons are much easier to use than heavy machine guns.

Compared with crane guns that need to carry a large amount of ammunition and may cause accidental injuries due to ricocheting during use, laser weapons completely avoid these shortcomings, can provide continuous and stable fire support for troops, effectively suppress alien creatures, and greatly improve The combat efficiency of the troops.

After all, a heavy machine gun can shoot tens of thousands of bullets when used in an underground tunnel for one hour. Even if the accidental injury caused by the ricochet is not taken into account, tens of thousands of bullets are the number that needs a truck to tow.

Now with laser weapons, the consumption of this part of ammunition can be completely eliminated.

Because of their satisfaction with laser weapons, the military even tried to install them on the spider robots previously provided by Chen Xin to the military.

Compared with the assault vehicle, the spider robot is obviously more suitable for the tunnel environment. Originally, Chen Xin also provided the military with a model equipped with a heavy machine gun. The military was also very satisfied with the use.

However, compared to the current version with laser weapons, the original heavy machine gun version is naturally less attractive.

If it were not that the production of spider robots was more complicated and time-consuming than that of assault vehicles, and the transformation of existing fire-supported spider robots would be more troublesome. The laser weapon module must be supplied to the production of assault vehicles first, and the military may want a large number of them. A spider robot equipped with a laser weapon.

But three months was too short. Even if the factory desperately produced, the total number of laser weapons delivered to the army was less than two hundred.

About one hundred of them were installed on the assault vehicle, more than fifty were installed on the spider robot, and the remaining dozens were used as replacements.

Among the dozens of spare laser weapons, more than a dozen were tentatively installed on the King-type Titan by some thoughtful technicians. After some tests, they also had good results.

With these laser weapons, it is naturally impossible for the military to just wait and select the best combat troops among them. The military sends them into the underground tunnels that have been temporarily turned into defensive tunnels to test these new ones. The use effect of the weapon.

It has to be said that laser weapons do have satisfactory results. In the military's tests, the units organized with laser weapons completed the operation at a much higher speed than the original offensive, and cleared a tunnel very neatly.

If it were not for the military's lack of plans to continue the offensive, let them retreat directly after the clearance, and it would be impossible to say that this tunnel would have been attacked in this way.

This is undoubtedly much more efficient than the previous military need to be very laborious and repeated sawing with alien creatures.

This undoubtedly greatly boosted the morale of the military and gave them more confidence in the counter-offensive plan. If they can continue to eliminate underground creatures with such an efficiency, the military even feels that they do not need to rely on the excavation plan. Clean out the alien creatures underground in the Dongting Lake area within a month.

Of course, the premise is that the aliens have no other moths.

But things are often out of expectation. According to Murphy's theorem, if a bad thing might happen, it will definitely happen. There is only a short distance left in the tunneling operation. The construction team expands the tunnel according to the original plan. In order to build the forward base, the accident still happened.

———————

During the tunneling process, detectors have been monitoring the ground around the tunnel to prevent the possibility of piercing an underground tunnel or cave during the tunneling process.

At the same time, it is monitoring the activities of alien creatures in the surrounding tunnels and caves to avoid being dug through tunnels and disturbing the construction.

The previous excavation work has been very smooth, relying on geological exploration to determine a route that completely avoided the existing underground tunnels and caves, during the tunnel excavation construction process, no interference from alien creatures was encountered.

But when the tunnel was less than 100 meters away, the construction team had already begun to expand the tunnel into a forward base, and the surrounding alien creatures suddenly went crazy toward the location of the tunnel. He punched the hole, vowing to dig through here.

This undoubtedly triggered the alarm. The construction team took an emergency plan and hurriedly evacuated all the workers. At the same time, in order to protect the precious shield machine, it was also disassembled in the shortest time and evacuated from the ground together with the evacuated workers. come out

It took three months to dig, but it only took less than half a day to quit.

After the construction team evacuated, the army quickly entered the tunnel and prepared for battle based on the detected activities of alien creatures.

When the first worker ant digs through the wall of the tunnel and emerges from it, a laser invisible to the naked eye hits its head instantly. UU read the book www.uukanshu.com and it will take less than a second. It exploded into a watermelon that was knocked out.

Immediately, more alien creatures poured into the tunnel and began to attack upward.

However, mankind has long been prepared. With the help of fire control systems, dozens of laser weapons are constantly firing at these alien creatures. Almost instantly, the tunnel is filled with the corpses of alien creatures, and even causes the alien creatures’ corpses. The offensive has been affected.

But these alien creatures did not stop, instead they continued to dig the tunnel completely at the risk of huge casualties, allowing more combatants and worker ants to flood into the tunnel.

Because the tunnel is almost a straight line, humans naturally do not have the limitations of fighting in underground tunnels, which are limited by the tortuous terrain and unable to exert the advantages of weapons. While the newly equipped laser weapons are showing great power, heavy machine guns and Not to be outdone, the light machine guns, while swaying large amounts of ammunition, sent the aliens to death.

However, out of concerns about the collapse of the tunnel, the military still did not use large-caliber artillery and powerful explosives.

The battle of Yan Guo's military to counterattack the underground alien creature nest in the Dongting Lake area was launched when the human side had not anticipated it, but was prepared.
