The two anti-aircraft machine guns were arranged diagonally in front and backward, and they could not be stacked together - otherwise they would be completely reimbursed by a bomb or a strafing attack by an enemy plane!

Moreover, if the two anti-aircraft machine guns are deployed too closely, the No. 1 gunner is likely to forget that there are friendly troops on the side when fast-tracking the low-flying enemy aircraft. Pen ~ fun ~ pavilion www.biquge.info

When the four big-mouthed sniper rifles roar wildly, the adrenaline is secreted wildly, and the machine gun spins around at a small angle, and if you are not careful, you will end your own people!

This is not something that has never happened!

Aleksandrov on one side was already observing the sky, and Lin Jun saw that there was also a rangefinder on a gas, "Who uses that?" ”

Landscoch was a little depressed and said: "Only Comrade Senior Warrant Officer can use it, we haven't learned it." ”

This thing is not a telescope, it is not something that can be said and done!

One rangefinder can only help one machine gun, the other machine gun is far away, and when the fight starts, the observer can just tear his throat and shout, and the shooter can't hear it!

If there were no rangefinder instructions, the combat effectiveness of that one anti-aircraft machine gun would have been less than half!

Is it okay to use military telescopes for distance measurement?

No kidding, the plane is not a fixed target, and it is not a reference in the sky!

"Rack it up for me! I got it! ”

This will make it clear to the naked eye that there are planes in the western sky, and there are quite a few!

The marshal is starting to fool around again! Others hurriedly began to persuade, but Lin Jun didn't listen, and shouted: "I'll jump to the air raid trench, what are you nervous about!" ”

Still disagree!

Now Landscoch came up with a solution, and it took a group of people less than two minutes to push a machine gun forward a few meters, and now Lin Junneng used the rangefinder in the air raid trench upright.

Tear your throat and shout, the anti-aircraft machine gun grabs on the flanks can hear it!

I won't be able to use a tripod now.

"Get out of the way! Be a target! ”

The two Gases were still parked on the lawn, which was really a mistake in the middle of a busy schedule. Hearing the voice of the marshal, someone immediately drove the car into the woods.

Lin Jun can use this without a tripod: he directly holds the two handles in the middle of the rangefinder, lifts the rangefinder, and rests the two shelves on his shoulders.

Fortunately, the rangefinders have been adjusted, otherwise it would be troublesome.

The zigzag-shaped differentiation plate in the eyepiece in front of me has become a three-dimensional mark that blends in with the scene!

If you are a person who does not have a strong sense of 'understanding' in your eyes, it is estimated that you will not be able to play this game after practicing for dozens of days.

Lin Jun is a pilot, he has practiced this thing for two lifetimes, although he only learned how to use it, but he has many skills. And the Nima used in two lifetimes is still the same model - when I learned jets in my last life, I used a 58-type one-meter rangefinder, which is almost the same virtue as the one at hand.

This one-meter rangefinder is very lightweight, and can measure not only the altitude of targets such as airplanes and clouds, but also the straight-line distance of ground targets.

There are Arabic numerals from 5 to 60 on the reticle in Lin Jun's eyepiece, representing the distance from 500 meters to 6,000 meters.

Because the principle of the rangefinder is to use the "body recognition" feeling between the pupils to measure the distance, some people have a strong three-dimensional sense of seeing the object with both eyes, and the three-dimensional sense of the measured object is compared with the three-dimensional sense of the number in the eyepiece, and the number that matches the feeling is the measured distance of the target.

Because people's "perception" is different, and the results they see can only be felt by individuals, and it is difficult to understand by speaking, how to get air defense observers to use rangefinders correctly is often very wordy in teaching, and even when training rangefinders, it is also a very nerve-wracking thing for troops.

Fortunately, Lin Jun belongs to the kind of person who has a strong sense of 'understanding'.

As for the target height?

Anti-aircraft machine guns will really not be used, just have an oblique distance, because the No. 1 gunner can see where the target is, not a large-caliber anti-aircraft gun anti-aircraft fire, many times the target is not visible at all, and it depends on the instructions of the shooting commander.

Before Lin Jun could see the model of the plane in the distance, Landscoch shouted loudly: "It's Junker 88, there is a formation coming towards us, with an altitude of about 3,000 meters!" ”

He was using that huge observation telescope to see more clearly than Lin Jun.

"What's the distance?"

My eyes are on the rangefinder, because this game measures the target at a distance of 6,000 meters at most, but I can't see the approximate distance.

"The distance is about ten kilometers, and the speed cannot be estimated! But it's coming our way! About 10 of them! There's also a smaller fighter escort on top! ”

This time it was Gurov, the sniper of the Guards, who made a cameo appearance as a distance observer.

Lin Jun wants to observe the relatively accurate distance, and the snipers have a very accurate sense of distance, and the distance is generally not wrong.

It's been a long time since I've used this toy on my shoulder, and I suddenly reacted and almost forgot about it, yelling: "Except for the machine gunner, everyone else has hidden their heads for Lao Tzu!" Alyosha! Vostov! ”

"Yes, Marshal!"

Lieutenant Vostov was the No. 1 gunner of the anti-aircraft machine gun on the side.

"Wait for my orders! Everyone is waiting for my orders! Everyone is waiting for my orders! …”

Lin Jun said so many times "wait for my order" why for?

He's not stupid!

There is no one who knows the pilot better than the pilot, and if the pilot is trained to be a guest air defense observer, he must be a first-class observer!

All of them were staring at the German fleet that was getting closer and closer, and their ears were always listening to the marshal's orders!

"All of them, get into the bomb shelter immediately! Enter the bomb bomb trenches! Immediately"

The voice is super loud, this is a lot of shouting!

At this time, even all the anti-aircraft machine gunners left their positions and jumped into the air raid trenches as quickly as possible!

Lower your body and look up at the group of enemy planes in the sky.

Don't hit the planes without anti-aircraft machine guns?

To fight, but not now!

Lin Jun knows Junker 88, and this distance has passed the closest distance of this kind of twin-engine dive bomber and dive bombing his position at this altitude!

The Junkers 88 is not capable of nearly 90-degree dive bombing like the Stuka!

Once calculated, don't hide and wait to be bombed!

The Germans are going to carry out horizontal bombing!

Those large-caliber anti-aircraft machine guns can't hit planes at that distance!

Reach!

Gray-black bombing points appeared near the front group, which was a nearby 85-mm anti-aircraft gun battalion that opened fire, but it seemed to have a mediocre effect!

Craned his neck and watched for a while, none of them were beaten down, and the German aircraft formation was not chaotic.

It's a pity that there are no 57-mm anti-aircraft guns, otherwise they will be able to deal with aircraft at this altitude!

"Squat down and hold your head!"

The rangefinder clearly saw the black bomb-bomb coming down! Throw the rangefinder to the side and immediately squat down with your head in your hands!

This time, Landscoch didn't dare to press down the marshal anymore, so he squatted down with his head on the side!

At this time, I hope that the bomb will not fall off my head!

Then why didn't Lin Jun run to the bomb shelter just now?

He could already see that the bombing routes of the German fleet were still somewhat different from the part of the villa where he was located—they should have targeted the buildings in the main part of the sanatorium.

Bombs are whirring down!

Sure enough, the earth shook and a huge explosion came from the flanks!

Listen to the sound and feel the vibrations, 500 kg there are, more 50 kg little guys.

In just a few tens of seconds, after an earth-shattering explosion, it seemed to be calm again—but it crackled, and even the air raid trenches smashed a lot of tiny clods and bricks!

Together, I saw the smoke and dust billowing on the other side of the woods! There were a few shots that were almost blown up and thrown into the woods, at most fifty or sixty meters away from Lin Jun and them!

It is estimated that those few pieces with poor accuracy are all 50 kg of little guys, if it is 500 kg, Lin Jun and his gang will not be so comfortable!

"Leave the anti-aircraft machine gunners, and the rest of the personnel immediately go to the sanatorium to rescue the wounded!"

It's not like his own side, although he was reminded by the air defense alarm in advance to start evacuating, some of the wounded are incapacitated, and Lin Jun really can't guarantee whether the evacuation over there has been completed in advance.

For each anti-aircraft machine gun, only the gunner, plus two observers, left only 8 people.

Everyone jumped out of the air raid trench, and when they saw that Landscoch was still standing beside him, Lin Jun didn't bother to say anything. At this time, the captain of the guard will not leave himself to run to save people no matter what.

Alyosha and the others quickly returned to the battle position, because the Germans were not only bombers, but also fighters came down to join in the fun!

"This is bullying us for not having small-caliber anti-aircraft guns?!"

Lin Jun set up the rangefinder and shouted loudly: "The oblique distance is 2500 meters, and the speed is 105!" ”

"Slope 2000! Speed 105! ”

105 is a speed per meter, Lieutenant Vostov they understand.

Several 190s rushed over from a height of less than 500 meters, and two of them came directly facing Lin Jun's villa! Through the rangefinder, I can even see that there is a bomb hanging under the belly of the plane!

190 can be used as a fighter-bomber!

Lieutenant Vostov and others fully cooperated, quickly changed the shooting of Zhu Yuan, but they never fired!

"The distance is 1500 meters! Speed 105! ”

As soon as Lin Jun finished shouting, an earth-shattering shooting sound sounded on the left rear side!

The sound of large-caliber machine gun fire was very loud, and it was still fired with four barrels!

Four ballistic shots towards enemy aircraft are clearly visible! Almost at the same time, another Alyosha-controlled anti-aircraft machine gun also fired!

Anti-aircraft machine gun firing and small-caliber anti-aircraft gun anti-aircraft firing generally do not hit the target with a long point shot, and the No. 1 machine gunner will chase the enemy plane according to the trajectory indicated by the tracer bullet!

But this will be almost a head-on shot, as long as you know the distance, a storm of machine-gun bullets will cover the German fighter in one fell swoop!

The body part of each ZPU-4 anti-aircraft machine gun was 4 KPV machine guns with a rate of fire of 600 rounds per minute! Every second, a four-barreled anti-aircraft machine gun delivers 40 penetrating 14.5mm machine gun rounds at the target!

Vostov and Alyosha stared at the enemy plane, and did not let go as soon as the pedal was pressed!

The 190-long plane was instantly hit by dozens of machine gun bullets with amazing penetrating power - the thick bulletproof glass windshield was easily pierced like papier-mâché, and the pilot's body was shattered!

A 12.7mm machine gun bullet can break a human body into two sections, not to mention the 14.5×114mm machine gun bullet unique to the Soviet Union!

With a relative speed of more than 1000 meters per second, no bulletproof glass is of use!

The 190's air-cooled engine was also scrap metal, and any 14.5mm machine gun bullet could pierce it through!

The German captain immediately turned into a ball of fireball and fell!

didn't have time to pay attention to it, and at the moment when the anti-aircraft machine guns ceased firing, Lin Jun shouted: "The distance is 1100 meters, and the speed is 110!" ”

The German wingman behind saw that the situation was not right, and accelerated to turn and detach!

If you don't break away, you can't do it! At a distance of nearly a kilometer, he was aimed at and shot by eight large-caliber machine guns, and Lin Jun had to flee for his life!

Rising to the challenge?

That's suicide!

Soviet 14.5×114mm machine gun shells were more powerful than many 20mm artillery shells - although the 14.5mm bullet had no explosives or incendiary charge in the warhead, and could not compare with the German 20mm gun shells with a high charge rate.

But the muzzle velocity of nearly a kilometer per second combined with a good ballistic velocity retention rate, at this distance, the powerful penetration of a 14.5 mm ordinary bullet is not at all comparable to that of a German shell!

Moreover, although the 190 aircraft gun is powerful, it has the usual problem of German aircraft guns: the muzzle velocity is not high!

A high muzzle velocity meant a long barrel, a large weight, a long shell, a large ****** and a high recoil, which needed to be avoided as much as possible in the design of German aircraft guns.

In air combat, the slow muzzle velocity of artillery shells and the bending point of long-range ballistics are not much of a problem, and German fighters generally do not fire at a distance of 500 or even 300 meters, and only seek to "kill the enemy with one shot."

But firing at the Soviet 14.5mm four-barreled anti-aircraft machine gun?

That's crazy!

The 20mm guns on German fighters can bend beyond your imagination at this distance!

"Want to run?! It's not that easy! ”

Lin Jun roared there with a rangefinder, although no one on the side could hear it: after a short pause, 8 tracer ballistics were already chasing the 190 dozen one after the other!

Such a shot was much more difficult to shoot than a head-on shot, but after a few seconds, the entire tail of the 190 was torn off and it fell headlong!

"**** German, go die! You rookie! ……”

With his eyes on the rangefinder and swearing in his mouth, it's been a long time since I've been so enthusiastic, just like when I flew a fighter jet and taught the Germans a hard lesson!

What a rookie! Replaced by Lin Jun himself, if he hadn't discovered that there were two four-barreled anti-aircraft machine guns here, he would have dropped the bomb and entered the dive in this kind of terrain, and then ran away while being close to the ground.

The anti-aircraft machine gun is located at a high place, and if it runs like that, it will not only increase the speed of the aircraft, but once it enters the depression angle, many machine gunners will not be as accurate as when shooting at an elevation angle.

Lin Jun roared there, and Vostov also shouted: "Change the barrel!" Change the magazine again! ”

The barrel temperature of the KPV machine gun fired in high-speed burst fire will rise rapidly, and too high a temperature will increase the spread of the projectile, accelerate the wear and tear of the barrel, shorten the life of the barrel, and in severe cases, it may even cause an explosion accident!

The machine gun of this model demanded that after more than 150 rounds of continuous projectiles per barrel in battle, the barrel had to be replaced!

The two No. 1 sought-after players estimated that the ammunition in the magazine box was almost gone, so they simply replaced it all!

It's lively!

Lin Jun didn't look at it, but Landscoch turned his head and saw it clearly: there were a lot of yellow bullet casings in front of the two four-barreled anti-aircraft machine guns, some of which were still steaming!

Gunners Nos. 3 and 4 quickly withdrew their cartridges, and gunners Nos. 2, 3, 4, and 5 immediately put on asbestos gloves - gunners Nos. 3 and 4 removed the barrels of the upper right and upper left, and gunners No. 2 and 5 removed the barrels of the lower right and left!

After changing the barrel, the No. 3 and No. 4 gunners fixed the four collars, and then began to change the four magazines.

The cooperation is not very skillful, but it is not bad - I just practiced for more than an hour today, and I didn't expect the guys to do a good job.

After a while, the two machine guns were restored to a ready state for fire. (To be continued.) )
