A community for your defence shitposting needs

Rules

1. Be niceDo 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.

Early 2000s FPSs promised me the XM8, and was left disappointed.

[–] [email protected] 24 points 1 month ago (2 children)

That mini timed grenade launcher that never happened was as sick as the stars wars space defense.

[–] [email protected] 21 points 1 month ago* (last edited 1 month ago) (3 children)

XM25 actually saw combat trials. The reported results were mixed, with reportedly conventional units appreciating it and Army Rangers looking at it as a burden. I'm personally skeptical to treat any of these public releases as entirely truthful, but it shows the XM25s were certainly issued in select numbers.

It was canceled for some arguably inane safety reasons, and speculatively because of a combat draw down and because the M320 opened up possibles of smart munitions which further tightened the XM25's niche.

[–] [email protected] 10 points 1 month ago (2 children)

I don't recall which of the handheld smart munitions guns it was, but one (possible many) had a glaring problem, every shot fired from it is a warcrime.
Exploding bullets below 400g are illegal since 1868. According to the treaty it doesn't matter what you shoot at but it's customary to only be illegal against humans and allowed against vehicles and aircraft.

[–] [email protected] 6 points 1 month ago

The actual ICRC statement on customary practice is that rounds under that size which are designed to explode on contact with people are considered a problem.

I don't think the OICW program was ever afraid of legal consequences. The combination weapon concept was simply impractical. Once it was split into two programs, the size of the grenades went up for practical reasons.

[–] [email protected] 6 points 1 month ago

It's not an exploding bullet, it's actually a very small mortar.

[–] [email protected] 7 points 1 month ago (1 children)

Interesting. After I got out, my interest in modern military fell off for a while until the Russia/Ukraine war, so there's a pretty big gap in my knowledge.

[–] [email protected] 7 points 1 month ago (1 children)

The OICW was split into two projects, a rifle and a grenade launcher. The grenade launcher half evolved into the XM25 which kept the smart feature but enlarged from 20mm to 25mm.

The downside was that it was a rifle sized weapon. Therefore it entirely replaced the rifle of whoever carried it.

The M320 fires the larger conventional 40mm HEDP rounds, but it is able to in theory fire larger smart munitions like the Pike missile. I speculate that the increased versatility, the simplistic design of the base weapon, the fact that it doesn't entirely replace a rifle, and the ability to fire the larger dumb munitions made it more attractive.

Even more anecdotally, if a 40mm doesn't do the job, a 66mm disposable dumb fire M72 LAW is the perfect way to deal with the kind of moderate cover that an XM25 is supposed to deal with.

[–] [email protected] 6 points 1 month ago (1 children)

I'm a big fan of the 40mm. I don't know that I'd like that. I liked having my 203, and knowing there were several others as well, which could be quickly switched to. This thing looks alright more of as a niche carry thing. Like, wanting a couple guys to carry one, but it's not their primary weapon. I can't fucking imagine stepping out of an apc or fast roping out of a helicopter with just that. Or maybe I'm just old and stuck in my way, I'm hoping maybe a little of both!

[–] [email protected] 3 points 1 month ago (1 children)

You're talking to somebody who thinks the M72 or the MK153 is the problem solver needed when a dumbfire 40mm doesn't work. Personally I am also biased against 25mm smart launchers.

[–] [email protected] 2 points 1 month ago (1 children)

My only regret of my service was not getting to fire the mk 19.

[–] [email protected] 2 points 1 month ago

mk19 - only got to fire one when attached to an MP unit. Wouldn't want to run one for a living but it was fun on the range.

[–] [email protected] 1 points 1 month ago (1 children)

It was cancelled because someone realized exploding bullets were against the Geneva conventions, and these were small enough to count.

[–] [email protected] 3 points 1 month ago (2 children)
[–] [email protected] 3 points 1 month ago

My bad, I was thinking of something else, these are 25x40mm, they're almost full size.

[–] [email protected] 1 points 1 month ago (1 children)

https://en.m.wikipedia.org/wiki/XM29_OICW

20mm, think the Geneva guidelines said anything sub 1inch counts as a bullet and can't explode.

[–] [email protected] 4 points 1 month ago* (last edited 1 month ago)

Furthermore, lighter grenades and exploding anti-materiel bullets have been introduced since. These developments have occurred without any objection. The military manuals or statements of several States consider only the anti-personnel use of such projectiles to be prohibited or only if they are designed to explode upon impact with the human body. - ICRC

I see where you are reading on the international legality, but the US and other nations looking at smart rounds weren't terribly concerned on the legal front. The OICW was canceled because a combo rifle and smart launcher weapon was simply too awkward to be practical. That's why it was split into two different weapons. Once the launcher was stand alone there was no reason not to increase the yield.

Also what ever happened to Metal Storm?

[–] [email protected] 11 points 1 month ago

It was never really more than a tech demo from my understanding. You had to muzzle-load the projectiles by hand, there wasn't a practical reloading mechanism.

That, and if there was ever a timing issue with the firing sequence or a misfired round, it would be like firing a round after a squib load I would guess.

[–] [email protected] 5 points 1 month ago

MR-C or bust.

[–] sp3tr4l 3 points 1 month ago

Soldier of Fortune 2 had a pretty devastating OICW.

[–] Technus 25 points 1 month ago (1 children)

I wonder if all the NCOs are bitching because they have to get their guys to clean their guns twice as often now.

[–] [email protected] 35 points 1 month ago* (last edited 1 month ago) (1 children)

Guns?

GUNS?!

I didn't know this was a piece of artillery. This is a rifle!

t.some sergeant who got promoted because he could run fast good.

[–] [email protected] 23 points 1 month ago (1 children)

Man, I fuckin hated those guys. "Gun? Is this the navy?"

[–] [email protected] 24 points 1 month ago (1 children)

It could be worse. You could be trapped in a room with people vigorously debating how many eyelets should be visible on a bloused boot and then asked to pick a side.

[–] [email protected] 32 points 1 month ago (1 children)

The most fun was getting laughed at by the special forces for having to wear a uniform at all. Those mfers would go to chow wearing the tiniest PT shorts they could squeeze into, and then literally hit the "randomize outfit" button after they selected the shorts.

Sf guy #1: booty shorts, One black boot, one tan boot, no shirt, vest, boonie cap.

SF guy #2: booty shorts, PT shoes, knee pads, ACU top, beret

SF guy #3: booty shorts, tan boots, elbow and knee pads, under armour shirt, full kevlar w/ nvgs

SF guy #4: booty shorts w/ visible whale tail, mechanix gloves, neon green mesh top, aviator sunglasses, Santa hat.

Not even kidding on that last one. It was the only one memorable enough to recall exactly the uniform.

[–] [email protected] 18 points 1 month ago* (last edited 1 month ago) (1 children)

My argument was observed while everyone in the room was wearing sneakers/low cut boots and half of them were wearing non spec pants. Literally nobody involved could actually blouse boots to regulation. It was one of those arguments borne entirely out of somebody wanting to start an argument.

I think I was wearing Czech combat pants at the time.

[–] [email protected] 8 points 1 month ago

Same guys trying to think of the worst possible "would you rather..."

[–] [email protected] 13 points 1 month ago

They're being kind, it's a carbine firing battle rifle rounds, that always works out well.

I look forward to its replacement by the M4A9. or whatever HK decides to call it this time.

[–] [email protected] 9 points 1 month ago (2 children)

Everything about this is wrong, this person know nothing about firearms, even though they really think they do.

[–] [email protected] 8 points 1 month ago (1 children)

Yes but the skub potential.

Yeah ok but armour piercing, 2km range and looks cool.
