The culture of my home island of Mallorca has a pretty deep link to slings, the ancient Greeks and Carthaginians both named us after our slingers, and later on we became a key Roman foothold in the punic wars partly because of the slingers, who became part of an elite unit of shock troops in the Roman Empire
It was our weapon of choice for defence, protecting us from pirates and would-be conquerors as well as farming, as shepherds used both slings and dogs to herd and protect their animals.
I find it pretty fascinating, I'm also a terrible shot with a sling, you have to try it to really understand how hard it is to aim when swinging a rock at something.
It is even harder to see sling bullets than arrows, right? I imagine fighting slingers would be even more scary than the normal ancient battlefield. Sort of like a proto-gun, in the sense that you have people dying with no warning.
Hey paisano! Not sure about you but me as a kid in Palma we had 3months of sling lessons during PE class!
