The title says it all but I noticed that Russians in the military cheer a type of ura which I have looked up to mean hooray or a battle-cry.
What are the origins of this, and are they related to the origins of the chant for the U.S Marines? Or is it just some coincidence of modern human language that 'ura' was used?
Thanks
Can't help you with certainty about its origins, but I can tell you the Ура battle cry (and all its variants) is used not only in Russia and by the Marines, but also is or was used by Germans, Polish, Bulgarians and so forth (you can see Bulgarian troops shouting it here https://www.youtube.com/watch?v=p5Yo8haGrDc#t=109)
I've seem many versions of its origins, and I think its exactly source is probably untraceable.
Jack Weatherford says in "Genghis Khan and the Making of the Modern World" it originated on the Mongolian battle cry "Hurree", which was then spread over Russian and eastern Europe during the more than two centuries of Mongolian occupation.
It makes sense, but doesn't explain why the Comanches used "Oorah" (which is supposed to mean "Foward!" on their language). There are more speculations at this Wikipedia article (http://en.wikipedia.org/wiki/Oorah_(Marines))
