For howitzers, there are many types of ammunition, and flares are naturally one of them.

In modern warfare, flares are actually not used much, the function of flares is to release at night, illuminating the sky as if it were day, so that it can meet the needs of night operations, such as hitting a certain fortification of the enemy, relying on this bright light, you can find the target and determine the location coordinates.

However, in doing so, it is also possible for the enemy to see itself, and in order to be able to see the enemy clearly without revealing his target, night vision technology is now becoming more and more popular.

The original night vision technology began during World War II, when it was just a solution of infrared headlights, which was also used for a long time, and even some tanks are still in use today.

However, advanced has also appeared, infrared imaging is one of them, but also the best night vision equipment, at night, the use of infrared to find the enemy's traces, can be said to be the most mature, the most suitable.

It's just that although flares are becoming less and less useful, this is also a necessary type of ammunition for all howitzers, and now, it is finally an opportunity.

Looking for someone at night? Well, look at my cannon to light the way for you, the cannon that was originally used as a killing weapon is now turned into a lighting tool, and has become a good helper for rescue, which can be regarded as an accidental role.

Hearing Qin Zhenhua's introduction, Ibrahim's eyes suddenly lit up, no matter how bright the searchlight is, it can't compare to the flare, that's right, just use the flare to illuminate!

"Now, we assign the lighting area to each gun according to its range." Looking at the other people with unhappy faces, Qin Zhenhua's face was very calm and serious, we are looking for someone now, you can take out the range of your own flares.

Dare to say that the range is useless?

The flares of the M109 howitzer, the firing range is the closest, only a dozen kilometers! Then the French, the British, and the Rainbow Country also participated, which is the farthest range except for the eastern powers, so that, according to their different ranges, they can be divided into areas to be illuminated.

It was already dark, and the convoy that went out to search still found nothing.

"Request for lighting for Area 13." A search vehicle was high in the dunes, illuminating ahead with the light of two headlights, and a guide from a waterless country with a radio in his hand, began to plead.

"Flares, shoot!"

The M109 howitzer, which fired first, fired at a nearby area, and the warhead of the tracer grenade, piercing the night sky, appeared a bright line, and in the eyes of everyone, flew into the distance.

There was a sparkle in the distance.

With the help of the bright light, the search team continued to search, and at the same time, the silent competition began again.

Flares are also technological!

If you want to illuminate, you must need a special lighting device, which is called an illuminating agent. Mainly metal combustibles, oxides and adhesives, etc.

The most common of these are metal combustibles, which, like the flashes of old cameras, are made of magnesium powder and aluminum powder, which, when combined, can produce temperatures of several thousand degrees Celsius and emit dazzling light.

However, only these are not enough, combustion needs oxygen, this continuous combustion, requires a lot of oxygen, which is achieved by oxides, generally barium nitrate or sodium nitrate, they can release a large amount of oxygen when burning, accelerate the combustion of magnesium and aluminum powder, and enhance the luminous brightness.

These are in powder form, in order to combine these together, there is also a need for binders, this kind of thing is generally made of natural dry oil, rosin, shellac and other raw materials, in addition to bonding the agent together, more importantly, it must also play a slow burning role, otherwise, it will burn all at once, it can only be illuminated for a few seconds, and after the illumination, it will be black again.

The brightness of the flare, the duration of the flare, the color of the flame, are all objects of comparison!

Qin Zhenhua looked down at his watch, the flare burned for about a minute, which was already good.

"Report, Area 27 needs lighting!"

Finally it was his turn to request, Qin Zhenhua waved his hand, only to hear a boom, and his own howitzer fired out the shells again.

The warhead flew into the sky, drew an arc, and in the eyes of everyone, the shell flew over Area 27, and then, the time fuse began to ignite, igniting the projectile, which threw the illuminator and the parachute out of the projectile, and the parachute slowly opened.

Under the parachute, a lighting box hung and slowly descended, and at the same time, the lighting agent began to burn, and in everyone's field of vision, everywhere they went, there was a bright light.

Thirty kilometers away, you can see it!

When the flare started to work, many people watched, watching the flare over there ignite, and in terms of brightness, it was obvious that it surpassed all other flares.

And, it lasts a long time!

A minute has passed, and it is still lit up, and two minutes have passed, and it is still lit!

It's almost usable for the daylight!

The big country in the east lacks night vision devices, and in order to be able to pull the enemy to its own level, it can only work harder in this area.

And what about the enemy's night vision devices? If you're lucky, you might be able to burn the enemy's night vision devices, and maybe you can even blind the enemy?

The flares were still slowly falling, and the search team finally saw something with the help of the bright light.

"Over there, there's a car over there!"

Derek is driving away, so if you want to search for Derek, you must first search for the car!

Just after seeing the car, everyone was ecstatic, and the search car headed towards that side, and when the light of the flare dimmed and disappeared, the light of the headlights had already firmly locked on the car.

Getting closer and closer, getting closer and closer, you can see that one of the tires has been broken, no wonder the other party is stuck here, driving alone, there will always be problems.

Hope Derek didn't go!

The search car passed quickly, but the mood gradually fell again, and the Derek, after the car broke down, actually left the car and walked away!

This guy is really looking for his own death, if he stays in the car, it will be easy to find, after all, the goal is big, he is alone, where did he go?

"Ask for another flare, we'll look for footprints!"
