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.

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.
Well that is insanely stupid, but it would net the recoil out to 0, if they are perfectly aligned...
Brilliant!
I like this idea better than the recoilless rifle conversion I was thinking about.
Simple, effective.
