For the soldiers on the front line, it was another sleepless night. The tracer bullets made tracks in the darkness and then drowned in the silent darkness. The Soviet soldiers fought back with their lives, and the German troops stormed the Soviet positions under the cover of heavy fire. Two hours later, when the sky turned white, the gunfire gradually subsided.

When the sun shines on the land again, the smoke in the crater has not completely dispersed, and the short exchange of fire makes the land full of the bodies of soldiers from both sides. Behind the corpse, behind a lush forest, are the houses and fences in the outskirts of Moscow.

These buildings have been affected by the shells, collapsed into ruins, and there are ruins everywhere, and among the ruins of these collapsed houses is a new defense line of the Soviet garrison. The Soviet soldiers who had withstood the test in the suburbs were no longer the recruits who had just been gathered.

In the hidden trench, some engineers of German technology department are discussing the performance of their new equipment on the battlefield with some soldiers who have just returned from the front line. In the trench not far away, some artillery observers are using the artillery mirror to search and record the targets they want to attack.

"This kind of night vision system for individual soldiers is very unstable. Personally, I don't think it can play any special role in the battlefield." A German official criticized the bulky new equipment under his feet. This is the latest single soldier night vision system developed by Germany. It uses infrared light source to search for targets at night. However, as the first generation of night vision combat system, this device has great limitations.

First of all, it is because the expensive equipment is very unstable in the battlefield, which is also the most critical point of soldiers in the battlefield. With a trace of dissatisfaction, the officer complained to the staff in charge of recording: "a total of 20 equipment participated in yesterday's attack, but there were various failures in three of them. And the battery of this equipment is too big. It's as heavy as carrying two radio stations. "

"Major, I want you to know that even if you carry three radio stations on your back, you can't see the enemy at night." While recording these problems, an engineer said, "apart from reliability and volume, there are no other problems with these equipment?"

"The image of this thing is not very clear. We have no way to distinguish some small things. In the night battle just now, it was because the soldiers who led the way didn't find the bottle under their feet and triggered the sound that they attracted the attention of the Soviet Union." This major was the commander who had just led a raid on the Soviet position, and another purpose of that battle was to experiment with this new weapon that had been put into the battlefield.

A night vision system called "vampire" is a powerful weapon for the German army to dominate the night in the future battlefield. However, the performance of this kind of weapon in the recent battle is very general, and there are other problems in the visual range, which makes it very difficult to popularize this kind of weapon.

"The visible distance of tens of meters is not enough. At this distance, the enemy can even use the moonlight to find our trace. Although they can't aim directly like us, it's enough to provide early warning. " The major continued: "in this case, the flares and all the weapons are fired together, which is enough to make up for their disadvantage in aiming at night."

Several engineers nodded after hearing this, and then continued to record these problems in the book. They know that after the development of this night vision device, it can definitely dominate the night battlefield in the future, but the current technical means are not enough to make them satisfy everyone.

This kind of equipment can't be directly brought to the battlefield without being tested. However, the experiments carried out in the rear and several local operations of the special forces did not encounter many problems encountered in the regular battlefield. For example, the problem of intensive fire suppression of flares has just been discovered.

"What if it's used for night defense?" A leading staff member suddenly raised his head and asked, "if we deal with the enemy's counterattack at night, is this effective?"

"Of course! If there are sentinels equipped with this device to carry out the task of sentry, it is really a very good idea The major thought for a while, then nodded, admitting a good use of this equipment: "if the enemy attacks first, we can find the other party more accurately, and we can give priority to fire to attack the enemy."

Others did not speak, and continued to write hard, recording the operational experience summed up by these front-line forces. While they were still recording, the four 75mm caliber infantry guns directly under the regiment began to fire fiercely. The roar of the guns covered many sounds, which made everyone's attention turn to the artillery position.

The light of the rising sun has not completely dissipated, and the dazzling sunlight still sets off the clear outline of the buildings in the distance of Moscow. But soon everything became restless. One after another, howitzer shells fell on the ruins of the collapsed buildings in the suburbs of Moscow, splashing gravel and debris again.

"What's the matter? I don't want to remind you to fire all of a sudden." The sound of the cannons obviously startled several engineers. As the shelling began, some German grenadiers began to carry their weapons and move quickly in the trenches. The battle seemed to break out very suddenly, everything happened in a flash“ What's going on? " The major, who had just answered the engineer's question, stopped an officer passing by, frowned and asked, "why did the support fire of the regiment suddenly open fire? What happened? "“ While observing the enemy's position, a platoon leader of the 1st company of the 2nd Battalion was attacked by the enemy's sniper. He was very accurate and hit the head directly. When the medical soldiers arrived, they were no longer saved... The 2nd Battalion asked for artillery support, so the regimental artillery opened fire. " The officer was held by his officer, holding his helmet in his neck, and answering as fast as he could. It's very common for such positions to fire suddenly. Generally speaking, the commander only confirms the reason for firing, and will not investigate whether the reason for the fighting is appropriate or not. Because after all, this is a battlefield full of fear and fear, and no one can make a clear investigation before making a judgment. It is possible that the two sides used tanks and artillery to fight for three hours, and eventually killed hundreds of people in a large-scale battle. At the beginning, the reason was that a soldier was too nervous and shot a haystack in the distance“ What the hell. " The major frowned, and then said to several engineers who came to investigate, "I'm very sorry. I can only accompany you here. The battle has started, and a platoon leader has been killed in my army. It's no small matter." With that, he ran to the hidden observation post over there, and the engineers and assistants, escorted by several soldiers, left the battlefield from the other side of the trench. Bullets were flying everywhere, crackling on the soil. The Soviet troops were unwilling to be outdone and fought back. Some 122mm shells were dropped from the German positions. Obviously, these 122 mm caliber shells belong to the Soviet Union's higher level support units, which may be division headquarters or military headquarters. In short, these heavy firepower support is not what this small German infantry regiment can cope with. Only a few seconds later, however, the German retaliation fire escalated again. The 105mm cannon began to join in the battle. The German towed artillery roared and sang. The German positions were littered with shells, while the Soviet positions were covered with smoke from the explosion. Although the Soviet support artillery had a certain advantage in caliber, in quantity, they could not defeat the German opponents who could completely crush them. Although the Soviet artillery was doomed to be suppressed, they still fired stubbornly, trying to find some memories of their glory. These Soviet artillery concealed themselves in the city of Moscow, desperately firing their shells at the German positions. However, only two or three minutes later, the German group army level artillery began to join the firepower feast. At this time, the Soviet Union's artillery was not so much fighting back as breathing. The 150 mm caliber heavy artillery has completely suppressed the 122 mm caliber artillery of the Soviet Union in caliber, while the 152 artillery in Moscow city is not many, so there is no way to effectively suppress the 150 mm caliber artillery group of the German army. After two rounds of German artillery fire, the Soviet artillery positions had given up resistance. In the past innumerable exchanges, the scene had been repeated innumerable times. The German army fired first, the Soviet Army immediately returned fire, and then more artillery joined in. Finally, the Soviet artillery was beaten dumb, the German army shelled again for a while, and then gradually stopped. Although they failed countless times, the next time the Soviet artillery would still fight back - they never seemed to care about their weakness, nor were they afraid of the strength of the German army. They used to be the largest artillery in the world, so they never give up. Even though they have lost countless times in this kind of artillery battle, they still dare to fight back when the next time starts. This is the artillery of the Soviet Union - Long Ling, who plans to make one more day today..... Happy April Fool's Day!
