During the Great Patriotic War, a three-line was often attached to the barrel of the guns: about the reasons

The calculations of artillery guns during the Great Patriotic War used various methods and means to increase the effectiveness of fire and train recruits. Here we are talking, among other things, about "shamming" with ammunition, with the barrels of guns.

Often, in the frames of the war years, you can see the original picture: the soldiers were attached to the weapon with a rope or wire a rifle. Usually it was the famous three-line rifle - the Mosin rifle, the development of which at the beginning of the Second World War was exactly half a century old.

For what purposes did the Soviet artillerymen use the legendary three-line, tying it to the barrels of the guns?

One of the problems facing the Soviet command was the need to train artillerymen in an extremely short time. At the same time, there was often not enough time, nor those specialists who could engage in such training in the rear. Another problem is how to provide the cadets with the proper amount of ammunition, which were urgently needed at the front?

The problem with the lack of ammunition for training recruits or cadets was solved in a very peculiar way. In order not to waste truly precious artillery shells, it was decided to use the Mosin rifle attached to the gun barrel for training. In this case, the trigger of the three-line wire was connected to the cannon trigger.

Details are in the AleX MoSS storyline:

At the end of the video, a 2X35 tank insert is shown.
Good machine.
There is also 2X30, it is revolving. That's where the jolly with the "seventh" shot)).

Normal shooting practice.
Good skill practice while minimizing weapon resource consumption.

About seven years ago, I wrote on VO memories of shooting with a "insert" ...
Eheh, Memory ...

Sergey,


At 2X30 ??
Not ah ...))
Does the electric circuit close?
Or wear and tear?
There was a problem with this drum.

Something happened at the Yurga training ground, but I don't remember any more, so the stories in the smoking room.
Tell me ...))

At 2X30 ??

On her "darling", she was created on the basis of a machine gun that did not go into series, and often, when, for various reasons, pollution or wear and tear, the whisper stuck, then the "insert barrel" immediately remembered his machine-gun childhood and shot everything that she had in the drum in one burst, and if there were six shells, then at the end the famous "seventh shot" took place, which, by the way, was not difficult to eliminate, but for a long time ...

[Aleks tv]

... whispered seized,

Did you keep the bolt in the rear position?
Hmm ...
What kind of wear should the liner have?))
I will assume that in Elani))


Found a photo of the entire "family".

No, I came across this while still in school, and then in the GSVG. And there they began to switch to 2X-35

Alexey, Sergey
The T-62 has a single-shot insert barrel. I will not add details, since this is not my profile (I am a driver), but it seemed to be all inside the barrel. But if they fired with the shutter of the gun closed or not, I won't say (I remember that when it was closed, but I'm not sure)

I did not see them live, I only remember that a regular shutter was used there. And when he served on the T-62M, we first used DShK machine guns, also single-shot, and then 2x35

[Aleks tv]

... In the T-62 single-shot insert barrel

Hello Volodya.

I didn't have to work with them.))
Heard, heard, but never saw.
How to fulfill the requirements of the UKS?
3 shots.
So it was fun for the towers))

The charger did not complain. Once, when shooting the gun with a regular projectile, I worked for the loader (it was interesting to try myself in this matter). In general, while the tank is in place - nothing complicated, but on the move, I would not undertake it.
When the tank was loaded with ammunition, we were constantly reminded that it is always necessary to load a unitar with a projectile down, because if you drop it on the projectile primer, it will not explode, since there are about five blockages inside it. But if you drop the sleeve, and the primer on something, it will work, and the energy of the gunpowder of one sleeve is enough to rip the turret off the shoulder strap. I also remembered that I could easily imagine myself in an embrace with a unitary, in the dangling space of the tower ... scary.

[Terenin]

I didn’t know about a rifle and a cannon. Thank you.

[Andrey Zhdanov-Nedilko]

We were also trained on the "foil" with an inset barrel. That's right, this is saving !!!

[alex aircraft]

Ersatz vkoadnoy barrel. Cheap and cheerful. During the Second World War is absolutely the right decision.

In the USSR army, and even now it is used in full for training, since the 14,5-mm cartridge has high ballistics

[bk316]

All large-caliber artillerymen in the training shoot through the barrels. It is very expensive to shoot just 155mm blanks. Greetings from Mulino
And the main thing is to screw the three-ruler coaxially - no worse than the barrel. Maybe it's even better, you get bored with the barrel on my gun, then shoot ...

This will be sent to Muleno next month. Ukrainian ensign (already master sergeants) promised to shake off.

Yes, he is a NATO spy! Pierced !!!!!

[bk316]

Are you talking about the caliber? Well 152 of course. Wrong. Sorry Sergei more than 35 years have passed .... The second military specialty has nothing to do with artillery. The son is already a reserve officer. But I think I can somehow fulfill the standard, I would have a normal calculation ...

By the way, I generally have a bad memory for numbers. This is because I am a mathematician. The main thing there is not numbers to remember, but patterns.

A bullet fired from an inset barrel has ballistics close to the projectile of the standard gun. A bullet fired from a three-line has a much flatter trajectory than a projectile - with standard sights, training will not work normally.

We had an artillery training of military unit 22267 in our city, I was with the officers I knew from the unit at the shooting range, they fired from a D-30 through an inset barrel. At first I was surprised, I asked "where are you going to shoot out of such a" fool ", I got ready, well, I think, wait, there is a boom and that's it. Then they explained to me what was happening, they even let me aim and shoot. only in the 90s they didn’t do it by acquaintance. Now there are no people, and the school was reduced, and the whole town was dismantled clean, and there were so many things - barracks, boxes for equipment, officers' dormitories.

[knn54]

In addition to saving shells and the resource of the barrel (taking into account the "non-firing" of the calculation) and safety. If a fighter several times could well and correctly send a TRACING cartridge to the target, he was trained already on real shells.

[Avior]

Plug-in barrel - common practice was and is when training gunners
It was probably not easy to fasten the three-line with high accuracy, because there are no adjusting devices to aim in accordance with the gun's sight.

[Proton]

It is possible not to shoot a bolted rifle, but to use THP and with the help of it they checked the alignment of the rifle barrels and guns.
Perhaps they did.

[Avior]

In any case, you need to set the rifle barrel, and there are no adjustments

But right away it was possible to teach the rules of correction ...

[Avior]

The ballistics of the ammunition from the standard and from the liner is not the same anyway, especially considering that the barrel is not an insert, specially designed, but just a rifle

They were also trained in direct fire, and for the slightest equation of ballistic data, when shooting with a "mosinka", the targets were made less than usual ...

[113262a]

But even grenade launchers are trained to shoot with a deposit! An insert is placed in the RPG-7 tube, and the student learns not to spectacle when fired over the ear, and even the hits are recorded. True, the first shot with a regular grenade is still terrible!)))

[alex967]

In our unit, they tied the AKSU to the RPG and shot them with a tracer.

[Snail N9]

Yeah, "know-how" ... Only since the 19th century. Even in the memoirs on the theme of Tsushima, it was written about this method of training artillerymen ..

[kytx]

I saw a photo in which a Soviet instructor teaches a Vietnamese crew to fire a gun
SCS is attached to the gun barrel
not tied with wire, but on brackets

[voyaka uh]

There were memories of a soldier.
Machine gun courses in 1943. Rear courses. Hundreds of cadets.
The cadets fired zero shots from the machine gun. Saving cartridges.
The whole course: disassembly-assembly, loading-unloading of the Maxim machine gun.
Moving with Maxim and marching on the parade ground.

[riwas]

On the English Chieftain (and on other British tanks, for example, the Centurion) there was a 12,7 mm sighting machine gun paired with a cannon.

[113262a]

On the T-10 there was either a KPVT sighting gun or a 23 mm cannon. I saw both options.
