A community for your defence shitposting needs

Rules

1. Be niceDo 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. Random twitter and YouTube comments belong in the Low Hanging Fruit thread.

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 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. These include Social media screenshots with a title punchline / no punchline, recent (after the start of the Ukraine War) reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Low effort thread 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.

Laser tanks are impractical. What if the enemy wears mirrored shades? That laser goes right back and kills you instead. You don't want your 100 million dollar tank to be taken out by a pair of Ray-Bans.

[–] BraveLittleToaster 92 points 5 days ago (5 children)

We can put shades on the tank to bounce it right back

Classic,but inappropriate. Tanks should not wear aviators, but big chunky goggle style Warby Parkers on sale $1.89

I guess war does change.

Disco Demolition Night. This type of war is not unprecedented.

https://www.military.com/daily-news/2024/04/24/army-has-officially-deployed-laser-weapons-overseas-combat-enemy-drones.html

The Army has officially deployed a pair of high-energy lasers overseas to blast incoming enemy drones out of the sky, the service recently confirmed, marking a major milestone for the U.S. military's ongoing development of futuristic directed-energy weapons.

The 20-kilowatt Palletized High Energy Laser, or P-HEL, "is currently deployed to support the Army's mission" in an undisclosed location abroad, a spokesman for the service's Rapid Capabilities and Critical Technologies Office, which manages its directed-energy portfolio, told Military.com.

I think the bigger concern is enemy UAVs wearing shades.

[–] [email protected] 11 points 5 days ago (1 children)

Yay for undisclosed location! Slava Ukraini!

[–] [email protected] 3 points 4 days ago (1 children)

It could potentially be in the red sea.

Big ass solar panels on the drone to capture the energy and charge the drones battery

I HATE THIS SO MUCH

and its soo awesome

[–] BigMikeInAustin 7 points 5 days ago

This is why I never open someone else's makeup bag.

[–] [email protected] 9 points 5 days ago

Doesn't that cause a nuclear explosion?

[–] [email protected] 5 points 4 days ago

The moment those mirrors stop being perfectly shiny they begin thermal collapse. Which is the real reason mirrors exposed to the atmosphere can't be used as targeting optics.

[–] Pirasp 12 points 5 days ago

That's when you go back to explosives, you don't even need shrapnel anymore, they are already wearing it!

I only we had something we could fire that do almost the same arc as that. That would be ballin'! So I'd call it ballistics

[–] [email protected] 25 points 5 days ago (1 children)

Ridiculous! You would basically need the mass of a planet for that to work.

[–] [email protected] 15 points 5 days ago

Dangit! We won't find that anywhere on Earth!

[–] [email protected] 7 points 5 days ago

Aiming such a thing would be more than an art.....

[–] [email protected] 5 points 5 days ago

That would work if the earth wasn't flat. As it is, you need to transport the artillery below their position and shoot them from there. Like Ender shooting through the ice clouds.

[–] [email protected] 31 points 5 days ago (1 children)

the tank is confused by its own reflection and attempts to fight itself

[–] [email protected] 5 points 4 days ago

This is why certain Army weapons are not appropriate for the Marines

[–] Hobbes_Dent 30 points 5 days ago (1 children)

Sigh.

Because good lasers are red.

[–] [email protected] 33 points 5 days ago

...the color of a blaster bolt (character-scale or starship scale) is determined by the quality of the gas used in it - higher quality gives you green, lower quality gives you red. The Rebellion didn't have access to the highest quality gas, and had to make do with the lower quality ammunition.

Huh, I guess I wondered but never looked it up until now.

[–] [email protected] 26 points 5 days ago (5 children)

If you fire a laser against a mirror, it bounces but raises the heat of the mirror so you end up melting the mirror and destroying the drone.

[–] [email protected] 23 points 5 days ago

I may risk being too credible here, but a $80 drone is a lot more expendable than a $40m laser tank. The drone can be considered a consumable. Hell, mark the drones down as ammo.

[–] [email protected] 21 points 5 days ago* (last edited 5 days ago)
[–] [email protected] 9 points 5 days ago

Depending on how long you do it, how powerful the laser, and how quickly it can cool off at the same time.

And like the other guy said, you can make really good mirrors if you only care about one wavelength.

[–] BigMikeInAustin 8 points 5 days ago (1 children)

But the drone stays in the air by making wind, which would cool down the mirror?

[–] [email protected] 4 points 5 days ago* (last edited 5 days ago) (1 children)

Unironically yes. If that's not enough, add water.

This was a real concept for the anti-ICMB 747. The idea was to loiter it outside air defense range and then send drones in as reflectors to target the lasers much closer to the threat.

[–] [email protected] 3 points 4 days ago* (last edited 4 days ago)

Interesting! Yeah, I think in the right atmospheric conditions this could absolutely work.

Why it's NCD, as drawn, is that shells already exist and do exactly this when fired on an indirect arc.

[–] [email protected] 11 points 5 days ago (1 children)

Buddy called inverse-square law

[–] [email protected] 18 points 4 days ago

Inverse square law is just a geometric limitation, focus your lasers more, problem solved.

[–] [email protected] 15 points 5 days ago* (last edited 5 days ago) (7 children)

Mirrors melt and break when hit with a laser of more than "pretty lights power".
This dude built a 2kW one with optics: https://www.youtube.com/watch?v=xNmbvaUzC8Q
mirror at ~ 4:30

EDIT: I know where I am, that video is too good not to share though. Vote away.

[–] str82L 6 points 5 days ago (1 children)

I rarely give my time to videos that long, but it was awesome for the full half hour. That guy's having fun. Thanks for sharing.

This is also how you check if your ass is clean.

We don't need Sky Ranger, mirrorbois or lasertank, we have shitballoons.
