Every time I see a pic like this I flash back on seeing "Zulu" on the big screen, the battle scenes with the warriors moving in perfect formation while drumming on their shields to keep step. I read some production notes on the making of that film, the Zulus had a blast, and actually had competitions to see who got to 'die' the most dramatically on screen.
It also cracked me up at a most unopportune moment some 20-odd years later when I realized the foley artists for a major motion picture had lifted the chants and shield drumming straight out of 'Zulu' for another big fight scene. Of course one did have to wonder at the sound of Zulu war cries echoing from a bunch of Roman-era Germanic tribesmen in the opening scenes of "Gladiator"....
