Good video. I'm a bit iffy on the history side of the video, as he leaves out some details (such as the Roman campaign for the Balearic Isles), or gives info with no source, like with regard to his comment on slingers on horseback. I've tried to find sources on mounted slingers but haven't found much... There's the "François Vase" from ~570-560B.C. that depicts pygmies armed with slings and riding he-goats into battle against cranes, but that's about it for mounted slingers in the art of antiquity. And I don't even know what to make of it

. So it seems that mounted slingers
may have been a thing, historically, but infrequently.
But I love the Colt Walker cameo at the 6:51 mark - I love good old cap and ball colts. And yeesh! That rib test is scary. I initially thought he missed, until he showed the slow-mo footage!
