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.

In what way? I could see the volume being a plus. but cold temps, rough usage, low infrastructure, water immersion all seen very concerning.
Cold temps: only where it's cold, can be mitigated through design, mostly only affects range. Diesel ceases to be liquid at cold temperatures, and much engineering has gone into making it and engines that run on it viable in cold weather. Most EV manufacturers have already figured out decent civilian tech solutions to this problem for EVs.
rough usage: EV's have less moving parts, less fluids, can have their parts better sealed against the environment (less need for air cooling overall) and don't "breathe" oxygen like ICE do. It's a lot easier to ruggedize things that move less, and low weight doesn't seem to be a high priority for most military vehicles.
low infrastructure: Logistics wins wars, this is a problem for gas vehicles too, and you either have the supply lines you need, or you don't. EV's make a lot more sense for operations within range of a base, obviously, but a base that can make its own power (either solar or nuclear) that fuels its defensive and patrol vehicles without an oil supply would be slightly more self sufficient. (Which is moot anyway, because humans need food). The military already contends with vulnerable infrastructure as well. This is an example of how fuel (and water) is often stored on US bases.
Water immersion: Yeah, combustion engines hate this too. Motors and battery packs can be sealed, an engine cannot be since it needs to consume air to function.
I think you're underselling the state of gas and diesel off-road vehicles and overselling evs in the very rough, very logistically detached space.
I obviously am not present in this conflict, and can only relate from a VERY distantly similar occupation: Wildland firefighting. I've not seen an ev that could live up to the way we used and abused trucks, side by sides and ATVs.
Edit Again, I'm not claiming I'm a combat veteran, or claiming firefighting is as demanding. Only that they're is some obvious overlap in how equipment is used, and detachment from logistics.
Often there would simply be a pallet of 5 gallon jugs we would stop by, to fill up. Sometimes 55 gallon drums with a hand pump. No charging infra possible.
With good glowplugs we got diesel trucks started in the early morning, in freezing temps.
As long as you don't flood the intake, ice vehicles are fine in the water. I've read they many evs have vents on the battery packs that don't agree with immersion, though this one especially I'm sure they are ruggadizing.
But we are probably both a bit off and it is in the middle.
I know this is changing, I just haven't seen an ev do it yet.
I legit look forward to seeing evs in such a role, but I'm not aware of big contacts for them yet
I only know of a single ev prototype being looked at by the US military, so it's not like they're going full steam ahead, I'm just saying that for some missions they seem viable. Maybe even preferable ("single use" short range drones perhaps...)
