A community for your defence shitposting needs
Rules
1. Be nice
Do not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.
2. Explain incorrect defense articles and takes
If you want to post a non-credible take, it must be from a "credible" source (news article, politician, or military leader) and must have a comment laying out exactly why it's non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.
3. Content must be relevant
Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.
4. No racism / hatespeech
No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.
5. No politics
We don't care if you're Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.
6. No seriousposting
We don't want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.
7. No classified material
Classified ‘western’ information is off limits regardless of how "open source" and "easy to find" it is.
8. Source artwork
If you use somebody's art in your post or as your post, the OP must provide a direct link to the art's source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.
9. No low-effort posts
No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.
10. Don't get us banned
No brigading or harassing other communities. Do not post memes with a "haha people that I hate died… haha" punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.
11. No misinformation
NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don't be an idiot.

From my experience in the army I know he's gonna ruck that Mk19 25 kilometers, set it up, fire two shots, and then it will immediately jam.
Btw it's not an Mk19, but an HK GMG. About 7kg lighter, so at least he got that going for him.
I figured it wasn't just from his uniform actually but I know zilch about european arms so thanks for clarifying.
taking 50 kg of gear into battle 💀 that's almost as much as I weigh
Holy shit 340 rounds per minute of...grenades. Anything you point that thing at is dust.
Well except for a tank.
Unless it's Russian
I don't know how it is in practice, but conceptually clearing a jam in a 40mm grenade thrower sounds nerve-wracking.
Nah, not nerve wracking at all. Grenade rounds don't explode without rotating a bunch of times first (this happens when you fire the round).
So if one were to get loose and roll your way you get the fuck out?
No, it has to spin a certain number of times and a certain speed. It's a safety feature to prevent injury if you hit something close to you when you shoot it. Basically the grenade has to rotate fast and travel far (~100 meters) in order to arm and then hit something to detonate.
Thanks!
isn't it also setback armed on top of that?
Possibly but why would they? The centrifugal fuze is sufficient.
It does seem to use both setback and centrifugal safety (M433, with M550 fuze) https://www.inetres.com/gp/military/infantry/grenade/40mm_ammo.html actual TM-whatever would be a better source, but i'll take this
Well you learn something new everyday. To be fair I might have learned it ~20 years ago and just forgotten it but interesting nonetheless.
It's additional safety factor that is easy to implement, and NATO armies take safety seriously
even russians are capable of doing it
Sure, but the centrifugal fuze accomplishes the same safety feature. It can only be armed when it is launched. Setback fuzes use the force of the launch to arm the fuze instead of the spin imparted from the rifling but effectively they're the same. I'd imagine they found it's safe enough as is and doesn't need the added cost of a second fuze.
Nah, you just have to make sure it doesn't roll more than three times. But if you roll it back the other way, it undoes it.
