Non mais un grand nombre de coups de feu devraient attirer l'attention quand même...

Une série de 5 articles étalé sur plusieurs jours ( jusqu'à vendredi) concernant le débat entre les  pros fusils d'assaut F88 et les pros M4 au sein de l'armée de terre australienne.

J'ai un fais un doublon dans le file armée de Terre australienne.

Il y avait un excellent article dans DSi à ce sujet.

Le bruit de l'arme est d'une part psychologique et vraiment pas à négliger.

Dans le cadres des essais menés par les Marines, on s'est aussi rendu compte que les chefs de section ne se rendaient pas tout de suite compte que leurs hommes avaient commencé à engager l'ennemi (vu que les détonations sont quasi inaudibles), mais aussi que le silencieux donnait parfois l'impression d'une trop grande efficacité des tirs.

EF88 vs M4

https://www.thefirearmblog.com/blog/2019/07/31/the-coves-five-part-comparitive-review-the-adfs-ef88-vs-m4-rifles/

Pour ceux qui ont la flemme de lire l'essai en 5 parties ...

...

In researching and writing these articles the author came to the view that the EF88 is a substantially better rifle than the M4A1 in most common-use cases for a service rifle because it is generally more accurate, more reliable, more lethal and easier to maintain, but that the M4A1 is better in some niche-use cases because it’s lighter, more ergonomic, handles better in most ways, and is more commonly used world-wide, resulting in a better parts aftermarket for it.

FN propose trois nouvelles munitions.

Deux en 5.56

Quote

(Herstal, Belgium) – September, 2019. Belgium-based FN Herstal, one of the world’s leading designers and manufacturers of small caliber weapons, will showcase newly-developed small caliber ammunition at Defense and Security Equipment International Exhibition in London, UK, from September 10 through to September 13.

Driven by military missions facing new threats and by recent trends such as environmental regulations, FN Herstal is introducing four new cartridges to its 5.56 and .50 calibers, delivering a still wider purpose-designed small caliber ammunition range.

FN PERMAX™ 5.56

5.56x45mm SS109 ammunition was originally designed by FN Herstal and adopted by NATO as the second official caliber in 1980. FN Herstal has now engineered the new FN PERMAX™ Enhanced Performance Round (EPR) 5.56x45mm cartridge so as to deliver superior performance in urban combat by passing through barriers such as windscreens, automobile bodywork, glazing or masonry to reach a protected target.

The new FN PERMAX™ 5.56 has excellent mass retention behind barriers, maintaining greater incapacitating effect.

Composed of a hardened steel penetrator and a brass body, the FN PERMAX™ 5.56 has been developed to meet and anticipate further environmental European and international legislations requiring use of lead-free ammunition.

FN PROPASS™ 5.56

The new FN PROPASS™ Armor Piercing (AP) 5.56x45mm cartridge is a further addition to the FN® range of ammunition, and is ideally suited when the mission requires defeating hard targets using 5.56 caliber. Featuring a tungsten carbide core, the projectile perforates armored targets or level IV ballistic protection composed of metal or ceramic inserts.

Both FN PERMAX™ 5.56 and FN PROPASS™ 5.56 cartridges are compliant with NATO standards – therefore, compatible with all weapons chambered in 5.56x45mm NATO.

These two newly-developed cartridges are qualified on FN Herstal weapons such as carbines and assault rifles (FN SCAR®-SC or FN SCAR®-L), and light machine guns (FN MINIMI® 5.56).

Une en .50 pour  l'entrainement

Quote

FN ARIA™ .50 RR

In the .50 cal ammunition line, FN Herstal has designed a reduced range cartridge that features a shorter travel distance limited to 3,500m.

Highly reliable without requiring re-zeroing or converted weapons, the FN ARIA™ .50 RR cartridge is dedicated to safe and effective training with .50 cal weapons on shooting ranges that are limited to the use of 7.62mm weapons. With a tracer version also available, the FN ARIA™ cartridge can be provided on belts (4 FN ARIA™ .50 RR + 1 FN ARIA™-T .50 RR-T) for realistic training.

The FN ARIA™ .50 RR cartridges are compatible with all weapons chambered in 12.7x99mm NATO cal (.50 cal), and are qualified on the FN® M2HB-QCB and the FN® M3 machine guns.

Alongside these new developments, FN Herstal proposes an extensive range of .50 cal rounds, including the multipurpose APEI (Armor Piercing Explosive Incendiary).

Il y a 9 heures, Kiriyama a dit :

Mais est-ce que ce fusil est vraiment en service en Pologne ?

Oui. Version classique (avec canon 406mm) est utilisé par la Défense Territoriale.

En juillet, 3 unités terrestres ont reçu 1412 fusils dans la même version. 21e brigade de podhale, 6e brigade aéroportée et 25e brigade de cavalerie aérienne. Ces unités feront partie de la brigade de la force de réaction rapide de l'OTAN en 2020-2021 (Very High Readiness Joint Task Force - VJTF). Cependant, les versions: courte, para et avec lance-grenades ne sont pas encore certifiées par l'armée.

Les Gardes Frontières ont également acheté environ 220 fusils MSBS.

Version bullpup a été développée simultanément avec la version classique. L'argent pour le programme provenait de différentes sources. Le ministère de la Défense a payé pour la version classique et le ministère de l'Économie pour bullpup. La priorité était l'introduction du fusil dans l'armée polonaise, qui préférait la version classique avec différentes longueurs de canon. C'est pourquoi bullpup attend la première du système MSBS sur le marché civil.

Proposition de 6.8 "hybride"

True-Velocity-6.8mm-Composite-Cased-Gene

U.S. ARMY SELECTS TRUE VELOCITY COMPOSITE-CASED AMMUNITION FOR NEXT GENERATION SQUAD WEAPON PROGRAM

GARLAND, TX – True Velocity composite-cased ammunition has been selected for the U.S. Army’s Next Generation Squad Weapon (NGSW) modernization program. True Velocity’s 6.8mm composite-cased cartridge was submitted as part of an overall NGSW weapon system in partnership with General Dynamics Ordnance and Tactical Systems and firearm manufacturer Beretta Defense Technologies.

True Velocity’s proprietary 6.8mm case design will provide end users with significant logistical and operational advantages over traditional brass-cased ammunition, including substantially increased effective range and muzzle energy, drastic reduction in cartridge weight and enhanced accuracy. The combination of True Velocity’s ammunition with the General Dynamics OTS weapon submission results in a state-of-the-art weapon system capable of long-range lethality, short recoil impulse, significant ballistic improvements and enhanced operational effectiveness for the soldier.

“True Velocity’s 6.8mm composite case design produces a level of performance, consistency and efficiency never before seen in small arms ammunition,” said Chris Tedford, president and chief operating officer for True Velocity. “Combining True Velocity’s innovation and technology with the expertise of General Dynamics OTS and Beretta results in a weapon system solution that exceeds NGSW requirements and provides the U.S. Army with a definitive edge on the field of battle.”

MSBS Grot

Conversion de la version classique en bullpup.

 

 

D'ailleurs, l'acteur Vin Diesel aurait dit en français « Je s’appelle Groot », « I am Groot » en version anglaise originale.

Il y a un peu entourloupe là. Entre les deux versions il n'y a pas beaucoup de pièces communes. Peut-être deux ?

„Grot”( fer de flèche) était le pseudonyme du général polonais. Maintenant, une telle mode patriotique. J'ai préféré les noms d'armes légères dérivées d'éléments chimiques, comme Beryl, Tantal, Glauberyt.

La culasse, le canon et le bloc de gaz sont les mêmes. Donc, tous les elements mécaniques. En particulier, la même culasse pour bullpup et version classique est une solution unique.

La crosse et la poignée ne sont pas identiques, car ce n'est pas physiquement possible pour bullpup.

Peut-être on peut voir mieux dans ce film, parce que le gars ne change pas le canon.
