I followed the cited source for the wikipedia claim, and it's just a guy writing a paper and saying his opinion. He's not citing anything deeper to cover his claim about an initial volley followed by targetting individual solders. Just because it's in a paper doesn't mean it's right, or even well-researched.

Sure, it FEELS right, and that does have weight with living history and experimental archeology, but I worry that "feeling" is the only thing anyone is actually citing in this whole conversation, including Wikipedia.
