actually -- selectively sticky cluster munition bomblets ;) (i.e. they stay there inert until handled or stepped on/run over, then stick to you and start to count down to kaboom)
White Phosphor has always worked quite well to 1. Destroy Weapons caches that you are going to leave behind a pair of WP Grenades generally speaking disable an artillery barrel from being reused. 2. Tanks and other vehicles tend to be vulnerable to WP.
@Secespitus I lost a total of 60 points, up to 20 in some SE’s, only 5 in others. Deleting without killing votes is a separate intervention so how and when they apply it might not have a hard boundary. So, if he didn’t have “a lot” overall, was he just a fan of me in particular? So I wonder if anyone else here was affected.
My idea for a gruesome weapon is a thin needle dart that can be guided. Once it penetrates the target, it sets off a core of nanoexplosive based on metastable Halfnium nulclear isomer. (Like in this Answer).
But nanotech disassemblers that eat through armor and then anything else is pretty mean. Have it self replicate, and you get a waeapon similar to the 1980’s remake of The Thing.
@JDługosz Yup or the remake of "The Day the Earth Stood Still".
I think it was Greg Bear in one of his books that the enemy destroyed the Earth to kill Humans because they saw them as resource threats, by launching a small Black Hole to collide with the Earth and let it consume it from the inside out. And there wasn't anything anyone could do about it once it was gravitationaly close enough to consume the Earth.
