Je ne sais pas s'il y a un fil approprié sur les mitrailleuses légères, et où il est ?

Donc je place ça ici...RPK-16 https://sputniknews.com/military/20160910/1045170624/rpk-16-ak12-ak15-kalashnikov.html

Ukrainian Modified DShK with Buttstock, Picatinny Rail, and Bipod in Ground Role

ukrainian-soldiers-fire-the-supe-1280x72

WarLeaks recently published a video on their Youtube channel showing Ukranian Paratroopers of the 1st Battalion, 95th Separate Airmobile Brigade in a live fire range shooting modified DShKs. This footage is actually U.S. DOD footage shot during Rapid Trident 2017, a multinational (U.S., Ukranian) training exercise that took place in September of this year. However, this isn’t the first time this has been done in the Ukraine, with a video a year older showing volunteer forces training with the same modified DShK as in the War Leaks video.

WarLeaks Video (the title Giant Super Sized Machine Guns is some excellent clickbait, a DShK is a DShK, there isn’t anything super-sized about it)-

There are three important modifications to pay attention to in both videos. Most obvious are the bipods. Theoretically, these heavy machine guns usually aren’t employed with bipods because they involve a large crew to employ and supply ammunition. Bipods are useful for proning out within a closer distance(200-600 meters) with the enemy, where you need to stay low to the ground for concealment and a better shooting position. With a DShK, your targets should be vehicles, aircraft, hardened defensive positions, or otherwise targets beyond the range of small to medium caliber ammunition. Going back to the first point, sustaining these machine guns requires at least a three-man crew to hump the machine gun and some ammunition, even more men if a rapid rate of fire is desired.

Second is the muzzle brake, which appears to be of a local Ukranian design and manufacture. In the 2016 video, the brake is actually censored out of all the footage-

Third is the buttstock assembly and what appears to be a sort of wire controlled trigger mechanism. This entire contraption is attached to the rear of a standard DShK via a mount that uses various fixtures to hold it in place. Essentially this allows a soldier to have an actual buttstock with the HMG, instead of the wooden spade grips that come standard with it. Making it very similar to the Soviet KORD. One interesting addition is the Picatinny block mounted on the adjustable stock (length of pull) where soldiers can mount an optic to make their aiming more precise.

The 12.7mm KORD is a Russian HMG design of the 1990s that happens to actually have bipods from the factory in some cases. However, when compared to the DShK, the KORD pales when considering the numbers made and actually utilized.

Le changement de canon est impressionnant de facilité et de rapidité !

C'était longtemps un standar le changement du canon en un clin d’œil sur les mitrailleuse...

En pratique les mitrailleuse pouvait tirer des heures ... pour interdire une zone ... on avait même des unité entière de mitrailleur, telle les compagnie de mitrailleur au sein des régiments d’infanterie qui se comportait comme des artilleurs.

Le mitrailleuse étaient préféraient, non seulement elle étaient plus mobile, mais leur tir courbe était beaucoup plus efficace que les éclat d'obus, pour l'antipersonnel. Pour du tir antipersonnel a l'obus il faut faire de l'airburst avec des fusée chronométrique ou de proximité et a cette époque c'est compliqué dans des régiments d'infanterie.

Pour que le feu soit continu malgré l'échauffement du tube ... sur les mitrailleuse portative, meme celle équipé de refroidissement a changement de phase ... on alternait très souvent les tubes, et cela en une fraction de seconde, de manière a ce qu'il n'y ai pas de répit dans le feu.

Aujourd'hui  on utilise moins les mitrailleuses portative dans ce rôle de barrage, mais la capacité de changement de canon en un clin d’œil subsiste.

The 100th Machine Gun Company was among the first to put into practice this long-range barrage technique — at High Wood during the bloody Battle of the Somme between July and November 1916. The company fired a staggering 1,000,000 rounds in just 12 hours.

That’s 10 rounds every three seconds for each of the company’s seven operational guns.

L'événement a utilisé seulement 100 tubes, pour les 7 mitrailleuse. Et la petit histoire veut qu'il n'y ai eu aucun incident de tir pendant ce million de coups tirés.

SIG Sauer’s .338 Norma Magnum Light Machine Gun

At their pre-SHOT Show range day SIG Sauer have demonstrated their new light machine gun, the SLMAG. TFB reported back in October 2018, that SIG Sauer had displayed their new light machine gun at the 2018 Association of the United States Army exposition. Now, thanks to footage from SIG’s range day we get our first glimpse of the SL MAG, chambered in .338 Norma Magnum, in action.

The gun’s designer, David Steimke, discussed some of the weapon’s features and noted that the SLMAG is a multi-calibre design with the new light machine also providing the basis for SIG Sauer’s entry into the US Army’s Next Generation Squad Weapon program. According to Military.com, Paul Snyder, SIG’s product manager for their new light machine gun project, confirmed that “We will not be submitting this, but we are working on the prototype opportunity notice for the U.S. Army.” Snyder described their NGSW entry as ‘very, very similar’ suggesting that their entry is likely a SLMAG chambered in the US Army’s new spec XM1168 6.8mm GP round.

The .338 Norma Magnum SLMAG demonstrated has a rate of fire of 600 rounds per minute and an effective range of 2000 metres. Developed as an answer to General Dynamics’ Lightweight Medium Machine Gun, the guns were likely intended to meet the need established by a Sources Sought Solicitation posted by the United States Special Operations Command and the United States Marine Corps back in May 2017.

The SLMAG reportedly weighs in at 20 lbs, lighter even than the M240B. The gun was demonstrated by Colin Murphy, one of the SIG Sauer Academy’s instructors and a US Army’s 3rd Special Forces Group veteran, he described it as “the lightest, most powerful [man-portable] machine gun on the face of the earth.” Soldier Systems reports that the SLMAG can be loaded without having to open the top cover and the direction of feed can be swapped. As the gun is multi-calibre it can also be chambered in the more conventional 7.62x51mm round and from the footage shared it appears to operate using the short or possibly long recoil principle of operation.

Un silencieux pour les mitrailleuse M2 .50 ... impressionnant.
