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.

MODERATORS
In the case of military vehicles, hydrogen is about the greenest option that we're gonna get. No one is going to make a battery powered AFV, because where the fuck would you charge it?
Just put solar panels on top, easy.
If you ignore the fragility (creates a weak point to disable the tank) and the slow charging rate, dust and debris from firefights would be a pretty big issue.
Dust is indeed an issue for fuel cells. It is a solved issue with air filters though. FCEVs brag about making the air cleaner than without them. Industrial equipment in ultra dusty environments also work on FCs. It does require regular filter changes compared to BEV though. An industrial equipment alternative is an FC setup away from the dusty environment to recharge batteries overnight and during breaks.
My comment was about solar panels
Solar deployments around mines can be far enough from the dusty areas. Today, tanks could bring a bunch of briefcase solar panels and when the tank is not moving and firing, its not that dusty. Cleaning is pretty easy for 20-50 panels too.
Fuel cells are the actual technology that require special designs to deal with dust.
