Gee, I dunno. What stopped the Union troops from adopting the "Rebel Yell?" That one is very well known and was definetely real. The Federals sure found it intimidating but never could really match it (yet they spoke the same language, had the same religion, and shared many ties although the "average" rebel soldier was more rural, etc.) "Spontaneous" rousing vocalization and banging can work a group up. Why? I don't know, gets your adrenaline going? It is cultural, and it is psychological, like psyching yourself up to lift something heavy. The Romans had a more scientific approach and were professional career soldiers. (I've seen their soldiers described as "engineers trained as infantry" since they did so much construction.) There was some innate fear of the "barbarians" as well and this contributed to it.

Haven't you ever had a game, or fight as a kid/teen/adult where you or your team worked yourself into a frenzy and truly intimidated an otherwise equal or superior foe? I could give numerous examples of this in my own experiences. It is almost surreal at times, but is effective when done with conviction (it is counterproductive and demoralizing to "fake it.")
