Simply put, the principle of night vision instruments in this era is actually very simple, just like flashlights shining on the road.

The flashlight shines in front and reflects back and sees it at the eyes.

However, the light of the flashlight can be seen by others.

Therefore, we need to change the light, that is, infrared rays, which cannot be seen by the human eye, but can be received by the receiving device.

At this time, in the front tank, the tank hand Trager stepped on the accelerator, listening to the unique sound of the engine behind, and then he released the clutch and the tank started.

In front of him was the driver's observation hole. He opened his eyes and looked forward, but he could only see that he could see that he was more than ten meters away, and he could not guarantee his safety.

"Continue to accelerate and move forward." The voice of the commander Coot Nespel came from the headphones, and he said: "The road ahead of us, please drive with confidence and boldness!"

Night vision devices are a new thing, with a very rare output. Only Guderian, who has always been good at studying technology, will equip his armored master with these night vision devices.

At the same time, the night vision instruments are very simple now, and only the captain has a receiving device. The other captains and drivers are still in a state of darkness, which means that they must fully trust the captain.

Nespel conscientiously directed his tanks and quickly moved forward, and behind them, tanks followed.

Every few tanks, there will be an infantry fighting vehicle, and the roof is covered with a big pot lid, which is the more powerful owl infrared headlight.

It releases stronger infrared rays, helping to illuminate the road ahead, allowing its own tank captains to have enough reaction time.

In fact, it is not impossible to act at night. When the moon is full of stars, car soldiers often turn off the headlights and turn on the cars. There are also some people who are born night owls and can see everything clearly in the dark.

However, their speed will definitely not be as fast as it is now. At the same time, their ability to observe at night is determined by the moonlight and starlight. The sky outside is quite dark now.

If there is no night vision device, the tank troops would be good to travel a few kilometers in an hour.

The tank's tracks were rolled through the field, and in just over ten minutes, they walked a few kilometers and arrived on the national border.

Nespel's eyes, staring at his receiver, saw the outpost in front, the outpost of the Luxembourg's border guards.

"Prepare the machine gun, at 11 o'clock." Nesper said.

Will it attract the resistance of Luxembourg's border guards when they are about to enter Luxembourg's border guards? The tanks on their own can easily crush them, but that will expose their own targets.

The loading hand pushed the machine gun and was ready. Although he couldn't see the distance clearly, he just did what the commander said. Moreover, as soon as the gun was fired, the bullet was mixed with tracer bullets, and the ballistics could be clearly displayed. Then continue to adjust.

Nespel was constantly observing the outpost. Soon, he saw the situation on the outpost from his infrared receiving device.

Several scouts, standing outside the outpost, raised their right hands towards them, and saluted with a standard salute.

Our scouts had already ambushed outside the outpost in advance. When the order was issued, they controlled the place!

Beautiful job!

Tanks rumbled along the road next to the outpost, one after another. An hour later, the troops behind were still moving.

This is a huge army!

No one noticed the situation in Luxembourg. After all, Luxembourg was an extremely tiny country. As small as two wars, this country had no resistance. Whoever came would surrender, and lived whatever he should live every day.

On the border, they only had a small number of garrison posts. When these posts were controlled, the German team's advance was simply easy.

At the same time, the backward communication system makes everything that happens here impossible to pass on.

Now, it is the early morning of May 10, 2019, a year ahead of history!

The powerful armed SS armored division entered the territory of Luxembourg on this dark night, and then penetrated into the Arden forest.

Everything is silent.

Meanwhile, there are intense preparations in all air bases in western Germany.

It was still pitch black outside, only the runway lights were shining. In the hangar not far away, Hans Urich Rudel looked at his landline.

Hans has made his 178th battle attack, and at the same time, he has accumulated 121 results.

Now, the Air Force is making an improvement in the system. When Hans's results have accumulated to 200, Hans must retreat from the front line. What is waiting for him is to teach the rookies in the rear, which makes Hans very upset.

What made Hans even more unhappy was that Germany now has thousands of bombers. Now, in the battle against France, they each assigned their own targets, and Hans' bomber squadron targets were not France, nor Belgium, the Netherlands, but Luxembourg.

This is simply killing a chicken with a ox knife. What did he do when he bombed Luxembourg?

The sickle swing operation is confidential. Only the senior officers who are directly responsible know the real combat plan. As for ordinary subordinate officers, they are not qualified to know.

If every soldier knew that he wanted to travel through the Arden Forest, he would be a big fuck!

Although he couldn't figure it out, as a soldier, Hans still knew that he had to obey orders as his duty.

Now that the plane has been maintained, the crew is preparing to hang two large 500 kilogram bombs under the belly of the aircraft.

It is only 4 a.m., and it is more than an hour before dawn. It is the turn of the Stuka bomber to set off after dawn.

Bored Hans walked out of the hangar and looked at the runway under the lights in the distance.

Under the dim runway light, a Juncker 52 transport aircraft is pulling a DFS 230 glider and taking off from the runway.

Three engines were running at full speed. Aunt Juncker was working seriously at this time, preparing to pull the glider behind to take off.

From a technical point of view, the entire World War II was definitely dominated by Germany. Tanks, aircraft, cannons, and almost many technologies came from Germany. Many of them were first applied to Germany.

For example, a glider!

Compared with aircraft, the biggest difference between a glider is that it has no power, and it relies entirely on descending from high altitude, constantly consuming potential energy, and finally landing. At the same time, since there is no power, the glider can be thrown away if it has been used, and there is no need to worry about the cost.
