Who are you, warrior?

A muscular warrior in a black helmet and armor stands with his back to the camera, facing a line of soldiers holding spears and shields, then turns to reveal a close-up of his determined face. The scene shifts to an older man with white hair and a beard, wearing ornate armor, standing before the same line of soldiers, then cuts to a close-up of a younger man in a helmet, his face visible through the eye slit, gazing forward with a serious expression. The setting is a sunlit battlefield or camp, with the soldiers arranged in formation behind the central figures.
