NonCredibleDefense
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.

Right, but you are going to want to choose a fuel that has the least chance of flaming up if you’re making a military vehicle.
Hydrogen has (compared to petroleum) a Wider Flammability Range, Lower Ignition Energy (0.02 millijoules) which is really low and much smaller than petroleum, and a higher diffusion rate.
All of which make it more likely to go kaboom.
Why? If something has gotten through the armour, your fuel is the least of your worries. I mean you are sitting next to a stack of shells filled with high explosives.
Well if the fuel is compromised there’s a larger chance it’ll ignite and reach the shells if it’s hydrogen as opposed to petroleum.
My point is that if your tank's armour is compromised by modern antitank weapons, it doesn't really matter where it hits you. You're going to be turned into chunky marinara, or your shells are going to cook off.
A pressurized fuel cell is already more protected than any fuel tank, and is smaller and lighter and more efficient than any ice engine. Which means you can add and divert even more armour to protect the cell and the occupants of the tank. Basically any danger associated with hydrogen is vastly overshadowed by the fact that tanks already carry high explosives. And that's not so dangerous that we're trying to replace them with non combustible weapon systems.
It's not like Rotem is new at making tanks, the K2 is one of the best tanks currently in production. If the engineers thought fuel cells increased the likelihood of catastrophic failure, I highly doubt they would have tried it with the K3.
Personally, I think most people are just buying into the propaganda that shut down hydrogen power in the first place. To my knowledge there hasn't ever been a death associated because of an explosion or fire involving a vehicle with h2.
