Antigravity, as a recap, is the phenomenon of creating a field that is free of / opposes normal gravity.
Supposedly Antigravity is real and can be created. The most common idea is to have a rotating superconductor (this follows supersymmetric gravity, where the two go hand in hand). Let's imagine that works too.
I have seen common applications be floating cards, real hover-boards, and probably some rocket propellers.
But I wonder how anti-gravity can be used for more... military aspects. I am not just talking about military vehicles, but more focused on the weapons themselves, like guns, melee and missiles. How could anti-gravity improve these aspects?
