I don't know if this is even possible but it seems like you could require particularly ominous weapons like assault rifles to undergo a bath of some kind of radiation. This radiation would be uniform and would allow security personnel to detect these weapons at a long range.

And then you can load them with these .... Radioactive_20Bullets
What else can we irradiate ? [normzone, Oct 06 2017]

Make the bullets out of sortof not-quite-deleted uranium?

Don’t be deterred by the 'bad physics' comments. They’re just jealous of your idea, which would solve all of the problems of assault weapons being in the hands of hillbilly types in an instant. Having said that, I'm going to have to add this fishbone for more personal reasons
[-] Bad breathe.

Nor do I, but a remarkable degree of consensus seems to be developing.

//..detect these weapons at a long range.//
To be detectable at long range, it will probably need to be rather a lot of radiation, which would be dangerous/deadly for the person holding the gun.
So, win-win!

I'm going to retract my bone and give you a bun because I don't want to feel like I'm piling on.

[+] Because you seem like a nice person. (Not a great idea though.)

I’m taking back my bone too. The breathe has improved.

[-] So, you idiots are fine with an idea that

a) won't work, but
b) if it did work, would cause your soldiers to sicken and die, and...
c) if they managed to survive, would be easily spottable by the enemies of your country, by design ?

Oh, and of course "assault weapon", because obviously the HB needs more deliberate abuse of language.

Baked, more or less. See link, and 'Gulf War Syndrome'.

Soldiers in Iraq were exposed to anti-nerve-agent PB pills, actual nerve agents, anthrax vaccines and burning oil. They were also using 'dirty bullets' and explosives made with depleted fissionable material. Dastardly, but true. Detectable with the right detectoring equipment, perhaps.

I got a C in college classical physics. So I guess I don't understand much.

Don't feel bad about it, [lepton]; just take the help file's advice and write about what you know.

//So, you idiots are fine with an idea that//

Putting a bone or a bun on a website that discusses silly ideas has absolutely no meaning whatsoever. Yes, absolutely fine with that.
