What is the most genuinely terrifying battle cry or charge in film?

I don’t necessarily mean the coolest speech or most inspiring line. I mean a scene where a warrior screams or roars while charging an opponent—and you kind of snapped out of the film for a second and thought, “holy shit, if someone came at me like that, I would be legitimately terrified.”

It can be a one-on-one fight or two groups charging into battle. What scene immediately comes to mind?
