Doomsday Bunker Upgrade

Although he came to inspect the position and really needed to understand the combat situation in the forward position, Chen Xin didn't have any intention of going to the frontier trench.

Climbing up to the firepower observation post of the stronghold, Chen Xin can directly overlook the entire position by using binoculars. There is no need for him to run to the forefront of the position like a big soldier.

The position that Chen Xin inspected looked like an upside-down "亼" shape, and the front line was the frontier trench to prevent alien creatures from attacking, even if viewed from a stronghold at least a thousand meters away. , still able to clearly see the fire of soldiers firing and hear the fierce gunshots.

Behind Yiheng, two oblique trenches are not only the extension of the front trench, but also its firepower supplement.

More heavy firepower was clearly arranged on the two trenches that spread out diagonally. Chen Xin even noticed that they had dug artillery positions between the two trenches, and deployed mortars and flattened anti-aircraft guns.

But judging from the appearance of those weapons, they should be old antiques pulled out of the warehouse, mostly from the Cold War period.

But I have to say that these old guys are quite easy to use. At least on this battlefield, these weapons designed during the Cold War have more advantages than modern weapons in terms of lethality.

This is not because technology has regressed, but that modern weapons are less powerful than those of the Cold War.

Modern weapons place more emphasis on precision and effectiveness, focusing on hitting with one blow and destroying the enemy at the lowest cost. This is also determined by the form of modern warfare.

However, the weapons of the Cold War were different. Most of them were prepared for the possibility of three wars, more to meet the needs of large-scale wars, and more emphasis on lethality and response to large-scale attacks.

So on this occasion, the old guys from the Cold War did perform better than modern weapons.

After all, steel-core bullets are far easier and cheaper than missiles to fight alien creatures, and they are also available in large quantities.

Seeing these weapons from the Cold War era being widely used now, Chen Xin couldn't help asking the major beside him: "I saw a lot of anti-aircraft guns deployed on the ground. Are these old guys easy to use?"

"It's really easy to use. Put the anti-aircraft gun on the ground, and it's very good at killing alien creatures." The major nodded and explained to Chen Xin: "The old-fashioned anti-aircraft guns are not as fast as modern anti-aircraft guns, but this is now On the contrary, it is an advantage rather than a disadvantage.

After all, modern anti-aircraft guns can fire hundreds of shells in a minute or two. Although the firepower is fast, it is not sustainable. What we need now is a long-lasting, continuous and stable firepower. In this regard, old things are more useful a little. "

"Understood, the output speed of modern anti-aircraft guns is indeed a bit high." Hearing what the major said, Chen Xin nodded slightly, and took note of this matter.

Chen Xin really didn't pay attention to this problem. When he was in China, the military of Yan Kingdom didn't have any troubles in this regard. They felt that the weapons had a high rate of fire, so they could naturally replace them with anti-aircraft guns with a lower rate of fire.

Especially on the defense line of Dongting Lake built by Yan State, anti-aircraft guns are not the main weapons. After all, every soldier in Yan State has a set of exoskeletons and the firepower output brought by the heavy machine gun is enough to meet the needs of the battlefield.

In addition, there are no flying units of alien creatures in Yan Kingdom, so there is no need for anti-aircraft guns to fight mosquitoes.

But when it comes to the European battlefield, it lacks the firepower configuration of ordinary soldiers with one heavy machine gun per person like Yanguo. It is indeed necessary for them to use anti-aircraft guns as a necessary firepower supplement.

Although the electromagnetic rifle provided by Chen Xin solved the problem that ordinary soldiers could not cause damage to alien creatures, although the electromagnetic rifle had enough penetration, its lethality could only be said to be usable, not excellent.

After all, in order to be compatible with the rifle bullets of Europeans, electromagnetic rifles have accommodated in caliber, and electromagnetic rifles also mainly emphasize penetrability, and the damage caused by the bullets themselves can only be said to be limited in power to alien creatures.

Therefore, on this battlefield, the tactic of laying anti-aircraft guns flat to hit ground units has become extremely effective and practical.

Coupled with those large-caliber mortars, it constitutes the main heavy fire strike force in the forward position, and it is also the main means of killing alien creatures in the European battlefield.

As for the more powerful and caliber firepower, it is the 155mm caliber howitzer attached to the stronghold.

However, in order to protect the barrel and save shells, these artillery pieces usually do not fire. Only when the forward positions are really unable to withstand it, they will roar to support them and push back the offensive of the alien creatures.

It's just that even with these heavy howitzers before receiving the support of Yan Kingdom, the front line of defense was often in a hurry, and the support of air strike force was needed to stabilize the front line.

There were even several times when aliens broke through the first trench, and it was only by relying on the output of heavy firepower on the second trench, coupled with the timely support of the air force, that the aliens were forced back again.

However, that time, more than half of the soldiers stationed on the position were killed.

Afterwards, this position encountered similar situations several times, but with the fire support provided by land ships and fighter jets from Yan Kingdom, the losses were smaller each time.

Recently, with powerful equipment such as electromagnetic rifles, exoskeletons, and power armor, the combat effectiveness of the first trench has risen linearly. It has been a long time since they have been breached by alien creatures. Now they even call The situation of artillery fire support has become much less.

It can be said that thanks to Chen Xin, their line of defense has become more and more stable.

But today, it seemed that the offensive of alien creatures was a bit ferocious, or they wanted to show off in front of the big man Chen Xin. The soldiers on the front line called for artillery support after a long absence.

Because the weather is too cold, all the artillery is tightly protected, covered with thick thermal insulation blankets, in order to prevent the artillery from being frozen or otherwise damaged.

After all, metal parts are easily damaged when the metal properties change at a low temperature of tens of degrees below zero.

Now that they were ordered to use artillery support, the artillerymen ran out of the bunkers at the stronghold, quickly lifted the insulation blanket covering the artillery, and then quickly adjusted the shooting elements to prepare for firing.

At the same time, another batch of artillerymen transported the shells to the gun positions, and with the calibration of the shooting elements, the loading of the shells was also completed.

Rejecting the major's request to let him enter the bunker, Chen Xin just stood on the observation post, watching the artillerymen complete their launch preparations, and then——

"Boom!" "Boom! Boom!" "Boom! Boom! Boom! Boom!" The God of War began its roar.
