Sounds like war cries haven’t changed much since coming off the battlefield and onto the soccer field. That’s the sort of thing a football team’s fans will yell about fans of the opposing team…
“War. War never changes.”
I suppose some form of “die, losers, die!” would be common but some warlords at some point found it too obvious.
A.k.a. “ululating.” It’s memorably featured in The Battle of Algiers.
LOL I wonder if there’s a way to measure the correlation between success in combat and good battle cries.
Also, after generations of use, there must have been a tune and cadence to the war chants. Think of the sports fan chants: they’re not just yelling out the words; they have a rhythm and pattern.
Here’s a passage from the novel where I first encountered the Cameron chant, D.K. Broster’s The Flight of the Heron. The hero, Ewen Cameron, is surrounded by British soldiers, and the word “strain” means melody:
"a familiar and most welcome sound came to him through the closed window behind him. No mistaking that strain; and that the soldiers should hear it too he turned a little and dashed his elbow, protected by the curtain, through the nearest pane of glass. In it flowed, wailing and menacing, the Cameron rant: ‘Sons of the dogs, come hither, come hither and you shall have flesh . . .’
The Imperial Japanese Army first started this tactic when faced with poorly trained Chinese troops with poor discipline and morale.
It also worked in the Malaya Campaign in 1941 and early ‘42 against mostly inexperienced and / or badly led troops.
WWI had shown that charging at machine gun fire or even troops with bolt action rifles mostly didn’t end well for the offensive, but the Japanese changed that.
They would do the banzai charges at night so it was harder to defend and they loved getting up close and personal with combat.
They would overload a point in the line and break through, which would lead to routing the enemy.
However, once they ran into better trained, disciplined and led troops, while it was an intense experience for all involved, the effectiveness sharply declined and became more of a ritual of suicide.
When I was a feral 1970’s child running the woods and creeks of Northern Virginia, we would often jump across the creek in places where one side was fairly high to help us get all the way across. When the jump was a particularly scary/challenging one, we always yelled “Jeronimo” as we leapt. It weirdly helped, as if we were calling his warrior spirit to boost our courage. I can definitely see how a good war cry would make all the difference in a charge.
The infamy of the rebel yell was not so much in that use though. They would send scouts to surround the enemy and yip all through the woods. It could make a few men sound like hundreds, and it was just a spooky sound. Yankee soldiers shivered when they talked about it echoing through the fog.
Clan Cameron represent!
Or just, “Bite me, you sons of bitches.”

That may be true, but the Camerons have three of the top five highest grossing films in history, and what do the Mackintoshes have? A raincoat?
Overpriced computers?
¿Por qué no los dos?
My full name in real life is just three different Scottish clan names.
Mine is a book of the Bible followed by a Napoleonic battle. But we digress.
I don’t know what your real name is, but to me, you’ll always be Deuteronomy Waterloo.
Half the books in Nevi’im are just dudes’ names and you go to the Torah 
I thought he was Judges Austerlitz
What about Hiob Leipzig?
But Isaiah Berlin has been dead for years.
One thing to note is that Banzai is not just a battle cry, thought that is where people outside of Japan first encountered it. Now it is often used like Hooray! or something akin to that. It means something like 1000 years, or Live Long and is a term that is used, though not pronounced in the same way in many Asian countries including China, Korea and Vietnam.
Of course the ultimate battle cry is Spoooon! as uttered by that supreme warrior The Tick!
