🧵Some stuff I've picked up from the 🇰🇵 parade yesterday (will be adding to it progressively). Starting off with this thing. Some kind of magazine fed self-loading grenade launcher perhaps ? Image
Grappling hook rifle grenade (actually pretty cool ngl)
Image
Image
Plenty of helical magazines abound as well, fitted to various models of the Type 88 rifles. Image
🇰🇵's K11 clone is still kicking about. AFAIK, the K11 project has been suspended in 🇰🇷. Image
High-cut helmets, NVGs and what looks like suppressed bullpup Type 88s. Image
Pretty large calibre shoulder-fired, disposable weapon. IIRC not entirely new, was observed in previous parades (but could be wrong on that). Image
KPA snipers with suppressed M76 clones. Image
Type 88 overfolders (Type 98 ?) with helical drum magazines. Image
Vehicle crewmen with SBR Type 88s. Scope does not make much sense for this role, but could be just to look ally on the parade grounds. Image
These odd-looking, fairly large, grenade projectors make an appearance again. @historicfirearm PIAT vibes for sure !
Image
Image
Another good shot of the SF looking guys with their suppressed bullpups. Image
More shots of the new disposable LAW. Overall length is not as long as expected. I'd say 105 mm or plus for the calibre.
Image
Image
Close-up of the GL I started this thread with. Bolt-action it would appear. Image
More of those weird rifle-like projectors firing PG-7 type projectiles. Image

🧵So a few weeks ago, I got to try out IWI's Arbel, a computerised electronic fire control system, that unlike other FCS', does not rely on a electro-optical based solution.
The Arbel system exists in two forms: a lower receiver for the Arad (and other AR pattern rifles) and a pistol grip module for the Negev family of MGs.
Image
Image
So how does the system work ? All it's doing is just slowing down the RoF, right ? Well not quite. There is a bit more going on. The heart of Arbel is a MEMS unit paired with a computing unit and a proprietary algorithm.

The rather bulky design of the ERA solution highlights the challenges of integrating ERA to lightly armoured vehicles. Its not quite a simple as slapping some Kontakt-1/5 on the sides of the hulll and calling it a day. In fact doing just that can make things worse.
How ? Well first of all here is a short primer on the fundamentals of how ERA works by @JonHawkes275
So what can go wrong ? Well, ERA, especially the early types, often can't completely stop a SCJ, there is often a residual element, usually the tip, that makes it through before the flyer plates can come apart. Hence why you still need backing armour to absorb it.

The AK-12M1, allegedly will enter production next year. Introduces some changes based on feedback from 🇺🇦. Features the new stock/ cheek rest combo and ambi fire selector from the AK-12SP. An AK-19 style, fixed flash suppressor replaces the earlier pattern brake.
The traditional rear AK sight, or the 2nd Gen diopter, have been replaced by a flip-up aperture. A 'П' battle sight (0.5 - 200 m, with additional night sight) and 600 m apertures are available. The 🇫🇮 and 🇮🇱 did this decades ago...
The new ambi selector ditches the 2-round burst capability, and apparently, also now mechanically locks the bolt when the safety is engaged (rather than just blocking the bolt's full range of rearward travel).

The recent-ish procurement by 🇫🇷 and the 🇳🇱 of Hirtenberger's M6C-640 Mk1 60 mm commando mortar, examplifies, I think, why NATO standardisation in ammunition is often less straight forward in practice than in concept. A little🧵: Image
It took the 🇳🇱 almost 4 years to qualify the M6C, with deliveries of 155 weapons having taken place in 2015. Ammunition qualification was completed in 2018, with the DMO granting full qualification for use with the Army, Marines and SF in early 2019. Why so long ?
Well, in 2016 two 🇳🇱 service members were killed, and another injured in Mali when a 60 mm mortar bomb suffered an in-bore premature detonation during a training excersive in Kidal 🇲🇱. The investigation found that the fuze malfunctioned due to heat and moisture exposure Image

Wanted to do a follow-up on the SPO Varna 'flamethrower' as there isn't much written about in either English or Russian. Introduced circa 2005, it was designed to compliment the RPO Schmel' and RPO PDM-A Priz line of launchers. Its RKhBZ code is MO.1.09.00
The launcher is the same as the RPO-A (marked with a red cross on the end caps), but inside, they are very different. The RPO fires a fin stabilised projectile filled with thermobaric, incendiary or smoke producing mixtures. The SPO houses a canister with a fixed launch motor.
The actual 'projectile' is a sausage like mesh 'bag' containing an incendiary mixture. In this case, 2.5 kg of OM-12 pyrogel, the same as used in the RPO-Z. The rear of the mesh container is fitted with some kind of igniter compound, which is itself ignited at launch.

Been pouring over some Sig patents for the their LMG, and thought I'd highlight some minor design changes from the production MX250 compared to the first prototype I saw in 2019. These are external changes of course, not much has been publicly disclosed about the internals so far
The production model (left) now has a continuous length M-LOK interface on the underside, and the profile of the upper portion has been tweaked. The prodution XM250 has lost its side folding stock capability, due to the necessesity of a battery pack for the powered rail.
Aside to some minor profile tweaks here and there, it doesn't appear to have changed all that much. Of course there is the 'rail on a rail' to properly accomodate the XM157, without interferring with the feed cover. Kinda validates the FN Evolys' design in that department.
