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.

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.
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.
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.
But the drone stays in the air by making wind, which would cool down the mirror?
Unironically yes. If that's not enough, add water.
A laser attack during a hurricane would really surprise the target.
Do not point laser at remaining eyewall.
not if you have total internal reflection
In all seriousness, wavelength-specific dielectric mirrors can approach six nines of reflectivity.
The hard part is hitting the mirror instead of the drone.
And keeping the mirror surface clean
Yeah I guess you can't pulse-ablate a mirror made of plastic.
Though it invites a backup strategy of spraying your enemies with molten drone.
Just make the mirror as wide as the drone! Oh, wait...
