To put it simply, in fact, the principle of night vision devices in this era is very simple, just like a flashlight illuminating the road. Pen, fun, pavilion www. biquge。 info

The flashlight glows, shines in front of it, reflects back, and the eye sees.

It's just that the light of the flashlight can be seen by others.

Therefore, it is necessary to change the light, that is, infrared, which is not visible to the human eye, but can be received by the receiving device.

At this time, in one of the tanks in the front, the tanker stepped on the accelerator, listened to the characteristic sound of the engine behind him, and then, he released the clutch, and the tank started.

In front of him is the driver's observation hole, he opened his eyes and looked ahead, but he could only see more than ten meters, far from ensuring his safety.

"Keep accelerating, moving forward." The voice of Captain Kurt Nespel came from the headphones, and he said: "We are ahead of the road, drive boldly and with confidence!" ”

Night vision devices are a new thing, and the production is quite scarce, and only Guderian, who has always been good at studying technology, will equip his armored division with these night vision devices.

At the same time, the current night vision device is very rudimentary, only the commander has a receiving device, and the other gun commanders and drivers are still in a state of blackness, that is, they must completely trust the commander.

Nespel dutifully commanded his tanks and moved forward quickly, and behind them, one tank after another, followed.

Every few tanks, interspersed with an infantry fighting vehicle with a cauldron lid on top of it, is the more powerful owl infrared headlights.

It emits more intense infrared rays to help illuminate the road ahead, allowing your tank commander to have enough reaction time.

In fact, at night, it is not impossible to act, when the moon is scarce, the car soldiers often turn off the headlights and start the car. There are even 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, and at the same time, their ability to observe at night is determined by the moonlight and starlight, and the sky outside is quite dark now.

If there are no night vision devices, then the tank troops can travel several kilometers in an hour.

The tracks of the tank ran over in the field, and in ten minutes, they walked a few kilometers and came to the national border.

Nespel's eyes, glued to his receiver, he saw the post in front, the post of the border guards in Luxembourg.

"Prepare the machine gun, eleven o'clock." Nespel said.

Will the imminent entry into Luxembourg's borders provoke resistance from Luxembourg's border guards? Your tanks can easily crush them, but that will expose your target.

The loader pushed the machine gun and was ready, although he couldn't see the distance clearly, but he just did what the commander said, and as soon as the gun was fired, the bullet was mixed with tracer bullets, and the trajectory could be clearly displayed, and then he could continue to adjust.

Nespel was constantly observing the outpost, and soon, he saw the situation on the other side of the outpost from his infrared receiver.

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

Their scouts had already laid an ambush outside the outpost in advance, and when the order was given, they took control of the place!

Well done!

The tanks rumbled along the road next to the post, one after another, and the tanks in front of them had passed an hour, and the troops behind were still moving.

It's a huge army!

No one noticed the situation in Luxembourg, after all, Luxembourg is an incomparably tiny country, as small as two major wars, this country did not have any resistance, whoever came surrendered, and lived every day as he wanted.

On the border, they had only a few garrison posts, and when these posts were controlled, the advance of the German army was a breeze.

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

Now, it's the early morning of May 10, 39, a full year ahead of history!

The tough Waffen-SS Panzer Division, on this dark night, entered the territory of Luxembourg, and then, burrowed into the Ardennes Forest.

Everything, quietly.

At the same time, in all air bases in western Germany, intense preparations were underway.

It was still dark outside, only the runway lights were shining, and in the hangar not far away, Hans Ulrich Rudel looked at his landline.

Hans has already made his 178th combat sortie, and he has already amassed 121 victories.

Now, the Air Force is undergoing a system improvement, and when Hans's results reach 200, Hans will have to retreat from the front line, and what awaits him is to teach the rookies in the rear, which makes Hans quite unhappy.

What makes Hans even more unhappy is that now, Germany has thousands of bombers, and now, in the battle against France, they are assigned their own targets, and Hans's bomber squadron is not France, nor Belgium, the Netherlands, but Luxembourg.

This is simply a knife for killing chickens, what is he going to bomb Luxembourg for?

The operation of the scythe was secret, and only the senior officers who were directly responsible knew the real battle plan, and as for the ordinary junior officers, they were not qualified to know.

If every soldier knew to cross through the Ardennes Forest, what a!

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

Now, the aircraft has completed maintenance, and the crew is preparing to hang two large 500-kilogram bombs under the belly.

Now, it was only four o'clock in the morning, and there was still more than an hour before dawn, and after dawn, it was the turn of the Stuka bombers to sort.

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

Under the dim runway lights, a Junkers 52 transport plane, towing a DFS 230 glider, takes off from the runway.

The three engines were running at full speed, and Aunt Juncker was working hard at this time, preparing to tow the glider behind to take off.

The whole of World War II, technically speaking, was absolutely dominated by the German side, tanks, planes, artillery, almost a lot of technology came from Germany. Many of them were first applied in Germany.

Like, gliders!

Compared with airplanes, the biggest difference between gliders is that they have no power, and they rely entirely on coming down from high altitudes, constantly consuming potential energy, and finally landing. At the same time, since there is no power, the glider can be thrown away once it can be used, and there is no need to worry about the cost.

At the same time, because there is no power, the glider will hardly make any sound during the flight, which can play the role of a surprise attack.
