I have thought about this for a while. Big creatures carrying massive slings. I watched video of Shadiversity confirming that I'm not the only one who thinks this.

Could you imagine a giant picking up a boulder, putting it in his sling? Then doing a run up Balearic technique? What that could do to a castle, not to mention the ear splitting whip crack?! If you had giant slingers, or even giant staff slingers throwing humongous pots of Greek fire?! There goes that castle idea.

Yeah, of course I'm talking about the creatures that are 3m tall and over. Ha ha, the MOVIE Balrog (I believe Tolkien meant the Balrogs to be only 7 feet) with a sling would be terrifying.

Bolos were used from horseback so I cant see why a sling wouldnt be. I imagine aiming might be difficult but if its a volley throw, that probably wouldnt be such an issue.

@TheMontananSlinger, I love the idea of a giant slinging. It depends on how big the giant is but if it is slinging legit boulders I think the castle is done for. Actually come to think of it, that must be how squirrels feel when we are slinging in the woods.

@kicktheotter I could be wrong about the points I try to make, but I believe that a sling, especially a long sling would be very difficult on horseback. Not only would the balance be a bit off trying to stand from the stirrup, as I believe good balance helps to increase accuracy and power. But the horse would also not really like its head being snapped by a whip of a sling after experiencing a low sling. A Bolo is fine because you can throw the entire thing at your target, not having to worry about dazing your horse as well as you probably won't need to generate a lot of force in order for the device to then wrap around the target. However Centuars could be great slingers as they'd be pretty good at the run-up.

Actually also underarm could work.

Does anyone know of any historical cases of mounted slingers? Someone, somewhere must of tried it.

@Morphy only in Soviet Russia, you'd find a horse riding a man.
