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.

The year is 2734. Humanity has conquered death, cured every disease (even the common cold), and colonized the stars. Yet on battlefields from Earth to Europa, the M2 Browning still thunders, the BUFF rumbles through alien skies, the M1 Abrams fires its 120mm cannon, and every Marine is issued a KA-BAR.
2066
Stationed on Mars to quell a rebellion
Become side door gunner for atmospheric dropship.
No miniguns or gatling cannons, just some metal brick with a pipe on one end.
Get sent in to extract some wounded.
Reach the evac zone and come under attack.
Hoard of rebels charging in with their new plasma guns and compact rocket launchers.
Let loose a stream of bullets.
The sounds of the rebel's screams are nearly drowned out by the heavy "Kachunk chunk chunk chunk" of the machinegun.
The wounded are loaded up and returned to base.
Inspect MG afterwards.
Thing was made in 1942.
Tunisia, Italy, and Germany are scratched onto the gun.
Scratch "Mars" on with a knife.
You forgot Vietnam, Iraq, Afghanistan, (and by 2066) China.
I would love to keep reading this story
Gunpowder is self oxidizing when ignited. As long as they used a non-evaporating lubricant on the actual mechanical components like graphite, and included a barrel liquid cooling loop, the M2 would operate totally fine in space.
Now I want to see a space-ready heavy machine gun with a big radiator attached
What about barrel cooling? Getting rid of heat is a major challenge in a vacuum.
That's why I say you need to provide a closed liquid coolant loop around the barrel that would ve integrated with your ship's heat management system, to replace the air cooling of the barrel.
you need to provide a closed liquid coolant
Will the blood of my enemies suffice?
to replace the air cooling of the barrel.
radiators work in space, just not as efficiently. fill 'em with ammonia, put more fins on for larger surface area, I'm sure the M2 could be adapted.

no because without gravity to pull them back down your bullets would just keep going up and up and over whatever you're trying to hit
Bullets don’t inherently go up when fired, they go straight out of the barrel, the barrel is just inclined because of the sight alignment. You just realign the sights, this isn’t a difficult problem.
Bullets don’t inherently go up when fired
yeah because of gravity
get rid of all the gravity and they'll go straight up
No.
don't come crying to me when your bullets go up so much they do a full loopdeloop and shoot you in the back of your head because you tried to fire them on the moon where there's no gravity
The moon has gravity.
i know we're on noncredibledefense but please take this seriously
See also Brigador: apart from the various lasers, exotic ballistics, and nightmarish chemical weapons it includes, there's also the prosaic "Mãe Dois." The tech entry leaves no doubt about what it is:
So... I don't see that anyone's brought this up yet so here goes:
If we are talking space space, you know, in orbit, transiting between planets...
You have to account for the recoil of each shot potentially sending your craft into a rotational spin, which can alter its trajectory.
Depending on the mass of your firing platform, you may have to expend a considerable amount of monoprop fuel, or energy in batteries to run multi axis centrifugal stabilizers....so that you maintain your desired trajectory.
Also, even if you are not in space, but on a moon or planet with significantly lower mass than earth... you're gonna have to do extra work to keep your tripod from dislodging from the ground, even knocking you backward with a sustained burst.
It might not even be practical to do a sustained burst or sweep, it might end up making sense to mod a slower cyclic rate into the thing, jerry rig a Kriss Vector counter weight style contraption to lower recoil.
Basically, the weight of everything involved goes down as G goes down... but the recoil energy remains the same... if you are in 0.5 G, basically, the recoil is twice as intense, as its pushing against half as much weight.
Each single shot would be more precise and travel farther in a vacuum or thin atmosphere and lower G... but sustained fire would be less accurate.
....Or maybe I'm overstating this effect? I'm too tired and lazy to attempt the actual physics calculations for recoil force.
All these problems are solved by firing two M2's in opposite directions, a net positive for everyone involved.
