Although he came to inspect the positions and did need to understand the combat situation of the frontier positions, Chen Xin did not have any idea of ​​running to the forefront trenches.

After climbing up the fire observation post of the stronghold and using the telescope, Chen Xin could directly overlook the entire position, and he did not need to run to the forefront of the position like a big-headed soldier.

The position Chen Xin inspected looked like an inverted "天" shape. The front horizontal line was the forefront trench that blocked the attack of alien creatures. Even when standing at a stronghold at least one thousand meters away, you could still clearly see the fire of soldiers firing and hear the fierce gunfire.

And behind one horizontal line, two oblique trenches are both an extension of the front trenches and a supplement to its firepower.

More heavy firepower was obviously arranged on the two trenches that were spreading diagonally. Chen Xin even noticed that they had dug gun positions between the two trenches, arranged mortars and flat anti-aircraft guns.

However, looking at 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 useful. At least on this battlefield, these weapons designed during the Cold War have more advantages in terms of lethality than modern weapons.

This is not a regression in technology, but the power of modern weapons has been reduced compared to weapons during the Cold War.

Modern weapons emphasize precision and effectiveness, and focus on hitting one blow and eliminating the enemy at the lowest cost. This is also determined by the war form of modern warfare.

But the weapons during the Cold War were different. Most of them were prepared for the three possible battles, more to cope with the needs of large-scale wars, and more emphasis on lethality and response to large-scale attacks.

So in this current situation, the old guys during the Cold War did play better than modern weapons.

After all, when fighting alien creatures, steel-core bullets are much better and cheaper than missiles, and they are also full of large quantities.

Seeing that these Cold War-era weapons are now widely used, Chen Xin couldn't help but ask the major beside him: "I saw a lot of anti-aircraft guns arranged on the position. Are these old guys very useful?"

"It's really useful. It's very good to use anti-aircraft guns. It's very lethal to 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 a bit rather than a disadvantage now.

After all, modern anti-aircraft guns, hundreds of shells may be fired in one or two minutes. Although the firepower is rapid, it is not sustainable. What we need now is firepower that can last and continuously and stably output. In this regard, the old thing is better to use."

"I understand, modern anti-aircraft guns are indeed a bit high in output speed." After hearing the major say this, Chen Xin nodded slightly and wrote down the matter.

Chen Xin has indeed not paid attention to this issue. At home, the Yan State military did not have this problem. He felt that the weapon had a high firing rate, so he could naturally replace it with an anti-aircraft gun with a lower firing rate.

Especially on the Dongting Lake defense line built by Yan State, anti-aircraft guns are not the main weapon. After all, all the soldiers in Yan State have an exoskeleton, and the firepower output brought by loading heavy machine guns is enough to meet the needs of the battlefield.

In addition, there is no flying unit of alien creatures in the Yan Kingdom, so anti-aircraft guns are not needed to kill mosquitoes.

However, when it comes to the European battlefield, there is a lack of firepower configuration for ordinary soldiers and heavy machine guns like the Yan Kingdom. They do need to use anti-aircraft guns as necessary firepower supplements.

Although the electromagnetic rifle provided by Chen Xin solved the problem that ordinary soldiers cannot cause damage to alien creatures, although the electromagnetic rifle has sufficient penetration, its lethality can only be said to be useful, but not outstanding.

After all, in order to be compatible with European rifles, electromagnetic rifles have been accommodated in caliber, and electromagnetic rifles mainly emphasize penetration. The damage caused by the bullet itself can only be said to be limited in power for alien creatures.

Therefore, on this battlefield, the tactic of launching anti-aircraft guns to attack ground units became extremely effective and practical.

Paired with those large-caliber mortars, it forms the main heavy fire strike force of the frontier positions and is also the main means for European battlefields to kill alien creatures.

As for the greater power and caliber firepower, it is equipped with a 155mm caliber howitzer on the stronghold.

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

However, even if these heavy howitzers were provided before they received support from the Yan Kingdom, the frontline defense line was still in a hurry, and the support of air strike forces was needed to stabilize the front.

There were even several times when alien creatures broke through the first trench. They relied on the output of heavy firepower on the second trench and the timely support of the Air Force, so they pushed the alien creature back.

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

After that, the position encountered several similar situations, but later, with the land rafting ships and fighter jets of Yan Kingdom providing firepower support, the losses were smaller than the other time.

Recently, there have been powerful equipment such as electromagnetic rifles, exoskeletons and power armor. The combat power of the first trench has been rising sharply. They have not been broken through by alien creatures for a long time, and now even the situation of calling for artillery fire support has decreased a lot.

It can be said that thanks to Chen Xin, their defense line is becoming more and more stable.

However, today it seems that the offensive of alien creatures is a bit fierce, or they want to show it in front of the big figure Chen Xin, the soldiers on the frontier positions called for artillery support for a long time.

Because the weather is too cold, all artillery is strictly protected and covered with thick insulation blankets to prevent the artillery from being frozen or other damage.

After all, metal parts change at low temperatures of several dozen degrees below zero, but they are easily damaged.

Now that we have received the order to use artillery fire support, the artillery soldiers ran out of the shelter of the stronghold, quickly lifted the insulation blanket covered by the artillery, and quickly corrected the shooting elements, ready for launch.

At the same time, another group of artillery soldiers transported the shells to the artillery position, and as the shooting elements were calibrated, the shells were loaded.

Rejecting the Major's request to let him enter the bunker, Chen Xin stood on the observation post, watching the artillery complete the launch preparation, and then

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