Our Kickstarter campaign has received $74,000 from over 2,000 backers! TV Tropes 2.0 is coming. There is no stopping it now. We have 4 days left. At $75K we can also develop an API and at $100K the tropes web series will be produced. View the project here and discuss here.
The polar opposite of a Screaming Woman. While a Screaming Woman instinctively yells at the top of her lungs at the first sign of terrifying danger, hitches up her skirts, and runs away from it, screaming all the way, a Screaming Warrior yells at the top of their lungs at the first sign of terrifying danger, raise their weapon, and then proceeds to charge headfirst into it, screaming all the way. Occasionally, the Screaming Warrior is the terrifying danger, at least to his enemies. Or friends.
Everyone likes a good Battle Cry right before a big fight, but this character just keeps on yelling even while the fight is well underway. Perhaps it's to intimidate their opponent, maybe it's just a habit, maybe it's to follow tradition, or maybe it's just cool to do. For bonus points, once the fight is over, don't be surprised if the character lets out one last cry of victory while standing over the pile of heap that was their opponent.
Not to be confused with Make Me Wanna Shout (where the screaming is an attack in its own right).
Make note that the trope is not limited to simply to screams. Loud, consecutive grunts and various roars very well qualify. A Screaming Warrior is most likely an angsty Badass, Action Girl, Proud Warrior Race Guy, Hot-Blooded, a berserker or all of the above.
An Onrushing Army just wouldn't have the same impact without this trope, so expect it to go hand-in-hand with examples of the former - the likelihoods formerly mentioned can be disregarded in Onrushing Army cases.
Compare Calling Your Attacks, Kiai, Leeroy Jenkins, Stab the Sky, Shouting Shooter. Contrast Tranquil Fury.

Anime & Manga
Subverted in an episode of Full Metal Panic? Fumoffu, the main character attempts to train a group of hot-headed yakuza members not to be Screaming Warriors when they attack someone.
Subverted in Utawarerumono: Oboro starts out as this kind of character... But is later shown going out of his way to not scream during battle, after realizing how ridiculous and inefficient it is.
The entirety of the Dai-Gurren Brigade from Tengen Toppa Gurren Lagann is just so goddamn Hot-Blooded, they always give the most badass screams ever while fighting. WHO THE HELL DO YOU THINK THEY ARE?!
The main protagonist of GaoGaiGar, Guy Shishioh, may very well be the king of this trope. He screams before and after just about everything he does. This is most apparent during the finale of the TV series, in which Gai is so enraged by his foe after it blocks his most powerful move, and seemingly kill Mamoru as well he completely forgets to do anything -but- scream. And totally brutalize the monster.
Guy powers up his Finishing Move in FINAL by adding screaming to it. Really.
Gemu giru gan go gufo... VIIIIIIIIIITAS!
He then cranks it Up to Eleven by the time he uses the Goldion Hammer (and its oversized, yet still awesome successor, the Goldion Crusher]]
Father Alexander Anderson in Hellsing Ultimate alternates between AAAAAMEN, and pure incoherent rage when fighting vampires. Including Alucard.
Seras Victoria let out enraged shrieks herself during her taking down of Zorin Blitz especially in the recently released English Dub.
Lampshaded and somewhat subverted in Vagabond. In an early volume, Yoshioka Seijuurou explains that beasts and men both scream loudly when they themselves are afraid of a fight and hope to intimidate their enemy and escape. Later we see this play out with Miyamoto Musashi himself, when he first fights inshun and is being completely outclassed, he lets out a wild scream as he's attempting to fight down his own panic and goes into a berserker attack in a last ditch effort. When that fails and he realizes that Inshun is about to kill him, he flees in terror before passing out from his wounds.
Musashi however would end up on the other end of this trope when he took on Seijuurou's brother Denshichirou the second time; it was Denshichirou who would do this, having an effect on everyone in attendance but Musashi, after Musashi asked Denshichirou to simply stop the duel. (If anything, Musashi is left wondering why Denshichirou was screaming when it'd just stiffen the muscles he'd use to swing his sword.)
Also subverted by Denshichirou years before against the surprisingly powerful and even intimidating Sasaki Kojirou, by declaring his lineage... only for Kojirou's companion to point out that 1) Kojirou probably didn't know of Denshichirou's father and 2) Kojirou's deaf.
"TEZUKAAAAAAAAAAAA!!" in The Prince of Tennis (appropriate when one is the slightly megalomaniacal tennis captain of a rival team facing off against Tezuka Kunimitsu).
Ayato Kamina from RahXephon fought like this constantly. He had a pretty bad habit of screaming his lungs off as he charged. Of course, the RahXephon is a mech enhanced by song and sound, so maybe that explains why it kicks so much ass.
At one point parodied, when he attempts to activate a special move in the laboratory... by screaming louder and louder.
Askeladd in Vinland Saga tries to tell Thorfinn, the protagonist, not to be one of these, explaining that a warrior that loses his cool often loses his head. Thorfinn, being Thorfinn, doesn't listen, so Askeladd is forced to teach him the truth of the matter rather bluntly.
Digimon Frontier, taken to ridiculous levels in a show that had not made a habit of it before.
Shinn Asuka from Mobile Suit Gundam SEED Destiny and his wrathful howls that make him sound like the most psychotic Blood Knight...except he fights because he wants peace. Badly. And he hates ORB. And boy, he will never let someone forget the ORB part.
The end of chapter 46 of Neon Genesis Evangelion gives us a 100m tall mecha with half of its chest torn off and covered in the blood of a 100m tall monster, which it just killed with its bare hands. And screaming of course.
Asuka, especially in her fight against the Mass-Production Evas in End of Evangelion, where nearly every sound out of her mouth is a wordless battle cry. Especially her last attempt at a kill where she starts squeezing the target's core with a demented growling; camera cuts away for a while then back where the growl amplified into a full-volume top-of-the-lung scream she continues until she sees the fake Lance flying towards her.
Shinji gets these kinds of moments occasionally, particularly his fight against Zeruel up until Zeruel oneshots him: then it's a berserk Eva 01 that does all the screaming. Unless you're going by the Rebuild movies, in which case, Shinji continues his rage.
In Ai Yori Aoshi, when the group is investigating "ghosts" in the darkened Big Fancy House, Aoi and Miyabi encounter what looks like a Bedsheet Ghost (actually Mayu trapped in a giant paper seal). Miyabi lets out a battle cry and charges with a staff she got from...somewhere. She winds up chasing Mayu through the halls until she's close enough to see who it is. Crowning Moment of Funny.
The Vision of Escaflowne's Van and Dilandau usually scream a lot when charging an enemy. A dead give-away of their intentions in both cases.
For comedic effect, Han Solo can be seen in Star Wars as the Screaming Warrior chasing after a detachment of Stormtroopers, blaster drawn, until he runs into their reinforcements, at which point he begins screaming and running away from them.
Joker has 2-4 guys like this in the '89 Batman film. One of them fights Batman in an alley with dual swords, and the other three fight in succession in the belfry scene at the end. The last guy, a Scary Black Man, provides the only real threat.
Appears in Sinbad: Legend of the Seven Seas: after being swallowed and spat out by a sea monster, one of Proteus's soldiers charges screaming at the monster, prompting Sinbad to remark to Proteus, "Give that guy a raise."
Even characters who aren't normally warriors can pick up this habit. As Jay and Silent Bob leap in to save Bethany from the Stygian Triplets in Dogma, Jay howls "SNOOTCH TO THE MOTHERFUCKIN' NOOOOOOOOTCH!"
Ardeth gets some Screaming Warrior moments too, notably in the sequel before he attacks Lock-Nah.
Last Action Hero. Jack Slater's daughter is attacked by one of the Big Bad's goons, and starts out a Screaming Woman... then continues to scream while beating the tar out of him (so his buddies will think he's still slapping her around and not interfere).
In The Matrix, Morpheus, when he busts out of the wall to take down an Agent to allow the others, including Neo, to escape. His capture sets up the rest of the film.
Beaten to a gruesome death in John Carpenter's Ghosts of Mars. The leader of the zombie-type-things goes through every possible emotive inflection of "RARRrrrrh!" in his first ten minutes onscreen, depending on his apparent mood. Then he gets to deliver them all over again, a few times each. Scarily enough, this makes him one of the best actors in the film.
Subverted in Young Guns. When the outlaws are seemingly cornered, Chavez appears to launch his horse at a cliff with a battle cry. Inspired by his courage, the other outlaws follow and to everyone's surprise they make it unscathed. When one of the other outlaws tells Chavez that was awesome and asks what the battle cry means in his native language, Chavez gives him a wry look and says, "Stop!"
The climactic fight of Undefeatable has both male fighters (especially the villain) screaming at the top of their lungs.
Sam Vimes from the City Watch books does this in Thud!!, when he's in a cave full of dwarves, going crazy from a combination of a demon in his head and not being able to read his son his bedtime story. Say it with me: THAT! IS!! NOT!!! MY!!!! COW!!!!!
The Nac Mac Feegle do this. In abundance. At the same time. With individual yells.
"...by nature dutiful, serious, literate, obedient and thoughtful people whose only minor failing is a tendency, after one drink, to rush at enemies screaming 'Arrrrrrgh!' and axing their legs off at the knee."
Which could possibly be read as "Knee Gnaw!", given that dwarfs have been known to bite taller opponents' legs or worse in the heat of battle.
In Interesting Times, Cohen advises Teach (a geography teacher who joined the Silver Horde out of curiosity) to imagine the enemy is everything he hates in order to work up a good beserk:
"Head teachers! Sports masters! Boys who chew gum!"
"Smoke pipes at me, would you? You! That boy there! Answer me back, eh! Take that!"
In Brian Jacques' Redwall series, the badgers and hares have their famous battle cry, "Eulaliaaaa!". Other characters often yell "Redwall!" or "freedom!".
Second Apocalypse: Cnaiur urs Skiotha has a combination of this and Badass Boast. During battle, he screams challenges to his enemies ("Who? Who will murder me?!") or about how many of their countrymen he has killed ("I bear your fathers and brothers upon my arms!"). At one point this is intimidating enough that his enemies see him as an avatar of their god of war.
Sigismundo Celine in Robert Anton Wilson's Historical Illuminatus Chronicles does this in the rare instances he's forced to fight, since his fencing teacher told him it throws the enemy off. When a mild mannered intellectual suddenly screams "DIEEEE!" at the top of his lungs, it certainly seems to work.
Charisian Marines in David Weber's Safehold series are famous for their howling war cry. They are also famous for being the best marines in the world, trained with muskets (and rifles & pistols), swords, and tomahawks. Just hearing them coming has been known to make lesser opponents flee.
Subverted in The Warrior's Apprentice after Miles observes his companion's assault on an empty room, complete with a "war whoop":
Miles: You know, it might be better if we don't yell, going in. It's startling. It's bound to be a lot easier to hit people if they're not jumping around and ducking behind things.
In Wraith Squadron, the pilot Runt has a Mind Hive. His initial pilot mind has a terrible tendency to scream a wordless, wavering warcry and plunge after the closest enemy, heedless of tactics, orders, or the fact that his craft's weapons would probably work better than ramming. His wingmate Kell helps cure him of this, and in time he apparently switches to a pilot mind that's more erudite.
Warcries abound in the works of J. R. R. Tolkien. Aragorn and …omer often use the names of their swords as battle cries, and Aragorn often uses the name of his ancestor, Elendil, as a battle cry as well. The Rohirrim have quite a few warcries, and Gimli has his famous Dwarven battle cry, "Baruk Khaz‚d! Khaz‚d ai-mÍnu!"
This is the trademark of B-movie action hero Reb Brown. In virtually all of his films, he'll let out a distinctively high-pitched scream during some action scene. This happens in Space Mutinyat the end of this clip which features his final confrontation with the villain.
Tyr Anasazi of Andromeda, not usually his normal style, but when facing a group of screaming monks, returned one of his own, causing them to flee.
Action Girl Ziva David of NCIS lets loose with one when invited to take a shot at Jerk Jock Tony DiNozzo's abs. It quickly degenerates into cooing and belly rubbing when she halts the punch an inch from her target and takes the opportunity to mock his conditioning.
Chiana of Farscape has a very distinctive warcry that can best be described as "BBBBBBRRRRRRIIIIIYIYIYIYYIYAAARGH!"
Recurring foes the Daleks of Doctor Who customarily scream "EX-TER-MIN-ATE!" before and during attacks on any living thing they perceive.
"Sealed inside your casing. Not feeling anything, ever. From birth to death, locked inside a cold metal cage, completely alone. That explains your voice. No wonder you scream."
In the Community episode "Modern Warfare" Jeff does this while redecorating the Dean's office with the business end of a paint ball gun.
Drink every time a warrior screams in Spartacus. You won't make it to the end of the episode.
Former WWF wrestler The Ultimate Warrior built a career out of being a screaming, snarling, grunting, face-painted lunatic.
Those who are aware of his behavior since his retirement are convinced it's not an act.
"Native American warrior" wrestlers have also traditionally fallen back on this trope, such as Tatanka.
SHIMMER/Ring of Honor wrestler MsChif screams at her opponent all throughout her matches. At the 2006 WWWC Tournament in Odaiba/Tokyo, Kyoko Kimura tried to shut her up by screaming louder. When that didn't work she tried to crush MsChif throat with a chain...which didn't work either.
Rebbeca Knox when not acting as Sweet Saraya's manager. She's also (unsuccessfully) tried to out scream MsChif.
Goldberg used to snarl and scream a lot, also. One memorable instance was at the 2004 Royal Rumble, when he was ambushed in the ring by Brock Lesnar. He snarls "You son of a bitch!" and literally hisses like a cobra. Prime Nightmare Fuel for a lot of the kids watching, no doubt.
Melina - though sometimes she's simply throwing a tantrum rather than trying to frighten her opponents, making her a mix of this and Screaming Woman. She does it so much, her screams are referred to as "The Primal Scream". She screams before doing both of her finishers, one of them appropriately titled the Last Call.
Kelly Kelly seems to be trying to out-do Melina in terms of screaming. It's a little unnerving to see the smiley happy Kelly suddenly turn into an aggressive Screaming Warrior whenever one of her matches gets serious.
Dolph Ziggler is partial to this. He often yells and hollers when entering a match and when he is in control of a match. He sometimes does this after winning as well.
Following his Face-Heel Turn in 2011, Mark Henry began a run of truly epic mid-match trash talk at a volume loud enough to be picked up clearly by the house mics.
Warhammer and Warhammer 40,000 have the Orcish battle cry, which they are known to scream until such time as they pass out. Say it with me: WAAAAAAAAAAAGGGHHHH!!!
Though you can't get the full effect of the WAAAAAAAAAAAGGGHHHH!!! shout unless it's coming from at least one hundred throats. All of which are attached to berserk, bloodthirsty monstrosities that are fully capable of ripping you apart with their bare hands.
Also: BLOOD FOR THE BLOOD GOD! SKULLS FOR THE SKULL THRONE!
Note that Cain himself has charged in battle yelling Waaagh to throw his enemy off: First in the short story Traitor's Gambit, then in The Emperor's Finest.
As for the Imperium: FOR THE EMPEROR!. Also serves as a battle cry for Alpha Legion Traitor legion. Yeah, they are a weird bunch.
And the Tau: FOR THE GREATER GOOD! Or alternatively TAU'VA!!.
Particularly notable are the Eldar Howling Banshees, whose shrieking, wordless battlecry is psychically amplified by their helmets to disorient the enemy. Their Phoenix Lord, Jain Zar, Storm of Silence wears original, much more ancient and powerful mask, capable of paralyzing the enemy.
Lucius the Eternal wears Armor of Shrieking souls, a suit of daemonically possessed armor that traps souls of his would-be killer. As name suggests, the thing is loud and its screams are known to be lethal on more than one occasion.
The list is fairly long considering the vastness of the universe. Most Space Marine chapters, both Loyalist and Traitor have official battle cry. Various litanies and chants also used extensively by all human and superhuman forces.
To the extent were the Necrons and Tyrannids are seen as more terrifying because they fight silently.
Also the Legion ofthe Damned are considered scary as hell because they are wholly silent (aside from the sound of their guns)
Dungeons & Dragons has multiple mechanics for this, the simplest being the Kiai Shout feat. All of them allow you to render enemies shaken or panicked by shouting at the beginning of battle.
Given the Truth in Television entry above, it probably isn't surprising that characters with the appropriate background in Deadlands can actually take a Rebel Yell as an Edge. But wait, weren't Native Americans known for their warcries, too? One thing that virtually any Native American warrior with his salt can do in the setting is a fast Ritual called "War Cry," which tends to earn favor with the War Spirits. Worth mentioning here because the Ritual has a higher chance to succeed if the player yells, too. What's that, you say? Role-playing? In a Tabletop Games? What are the odds?
Trollkin Fell Callers are born with innate vocal powers which are so strong they can deafen opponents within their immediate vicinity if they yell loud enough.
Dead Space sees the otherwise-silent Isaac Clarke grunt, yell, and scream his lonely way through an entire army of undead monsters that used to be the USG Ishimura's crew. He does this because he's scared shitless and it helps him cope.
The character properties screen in City of Heroes includes a field labeled "Battle Cry".
BURN BURN BURN TO THE GROUND BURN TO THE GROUND BURN BURN BURN BURN TO THE GROUND BURN TO THE GROUND BURN BURN
Bloodline Champions has the Vanguard bloodline, in which four of their nine abilities involves yellling.
Double H from Beyond Good & Evil. He charges into battle with a healthy CARLSON AND PEETERS! whenever he attacks, and he enjoys yelling in general.
While in Rage mode the Arbiter of Halo Wars will often yell: I AM THE ARBITER!, just in case you forgot.
The Elites are all basically this trope. Get close to a high ranking one in Halo 2, he'll drop his weapon, scream (while shaking his fists in the air), and draw his energy sword in an incredibly dramatic fashion. While swinging it, he'll yell variations of "Hiya!". The Arbiter in Halo 3 is even more so; get in a close-quarters fight, and it's guaranteed you'll hear a primal roar followed by the sizzle of energy sword on flesh.
Their UNSC counterparts, the SPARTAN IIs, are the absolute opposite, and it even manages to unsettle Thel 'Vadamee.
Grunts will scream hilariously ("Aiyaiyaiyaiyaiii...!") when they go nuts and kamikaze you. Most often drowned out by the player's "Oh, Crap!"
His Wind Waker incarnation is particularly shouty; just try using a Hurricane Spin and listen to him go!
Diablo 2's Barbarian has an entire tree of skills which involve roaring to either buff himself and his allies, or de-buff enemies. One of the highest-level war cries, simply called War Cry, deals direct physical damage.
Grom Hellscream (pictured above), chieftain of the Warsong Clan from Warcraft II and III. In a scene in one of the books, he makes an enemy drop his defences by screaming so loud it physically hurts him.
One of the reasons he follows Thrall is that Thrall was barely annoyed. His most memorable appearance in the game was doing this to a giant demon, and winning.
Even his weapon screams. His axe Gorehowl has special notches and holes in it. When it is swung, air rushes through the holes and makes a howling noise.
Druids of the Claw and various creeps have the Roar ability which gives a big damage boost to friendly units in range. The Howl of Terror ability decreases enemy attacks, and is most notably used by the Pit Lord, a gargantuan and particularly unsubtle demon.
The Beastmaster's ultimate combines it with Onrushing Army: You hear a loud, echoing roar... and suddenly a stampede of exploding thunder lizards is decimating the enemy army.
Whle not exactly warriors, the undead's Banshees attack by screaming.
World of Warcraft: Warriors have several shout abilities giving a range of effects, although these could not directly deal damage until Mists of Pandaria introduced Dragon Roar, an attack that hits all nearby enemies and briefly stuns them (and a Shout-Out to Skyrim). Druids echo these shouts in the roars they have when shapeshifted into bears.
JOHN J. KEESHAN, the Alliance equivalent of Rambo, fills this role quite nicely. One of the quests you do with him is even named "AHHHHHHHHHHHH! AHHHHHHHHH!!!"
Heroes of Might and Magic 5: Orc Barbarian Heroes have their own brand of magic, called War Cries. One of them deals direct damage by making all his units shout at an enemy.
Brick. Even outside of his berserk fury, he'll still scream about blood and his deep love for it, if you simply stand still during a bout of berserk, he'll alternate between hollering at the top of his lungs, laughing uncontrollably at the top of his lungs, and progressively discovering new tops of lungs he didn't know he had.
Salvador from Borderlands 2 does much the same when he berserks, though he only really screams at the beginning. While Brick continues to thunder as loud as he can throughout his rage, Salvadore will instead give a battlecry at the beginning of his rage and swap to quiet panting, growls, or even humming "In the Halls of the Mountain King". That said, when entering his rage, he'll still scream things like "VIOLEEEENCE", "START RUNNIIIIING" and even the words "BERSERK SCREAMIIIIING" at anyone around him.
Krieg from the same game also has various psychotic cries of rage, as well as some rather sadistic threats. With the Raving Retribution skill, he'll also start going on completely nonsensical but surprisingly well-articulated rants when he's set on fire.
Scarface: The World is Yours has a lot of screaming. Various gangs scream en masse while charging into Tony's superior firepower. Tony can scream right back whenever the player wills. And of course, during the 'rage/invincibility' attacks the screaming is out of control (and foul).
Asura is a new triumphant example for this trope, considering that he's basically the embodiment of wrath, a title that is in no shape or form undeservedin the slightest. This is taken Up to Eleven with Asura's Berserker and Wrath forms. All he does is scream.
It got so bad that Liam O'Brien in fact was reportedly spitting up blood from the recording sessions for the game's English dub. Dude's a trooper.
The Soldier from Team Fortress 2, as seen in the trailer. The Heavy Weapons Guy as well.
The Demoman will let off a mad Scotsman's scream at the top of his lungs when he triggers one of his shield charges, and start drunkenly shouting Highlander quotes if you kill an enemy with a sword or axe.
DEMACIAAAAAAA! If you don't hear this every couple seconds it's not Garen, it's an imposter.
The Infected of Dead Island. You'll hear them the first time when installing the game on PC. It's not a good sound. At all. Failing that you'll hear it on the beach and it's so unnerving your character will become freaked out.
Chivalry Medieval Warfare has a dedicated Battle Cry button. When standing still, you'll taunt your enemy and brandish your weapon. When sprinting, the button turns into a "scream at the top of your lungs" button (which everyone spams). The Vanguard class in particular screams a lot, especially when executing his sprint attack. Turning on low gravity and jumping into the air causes characters to start screaming in terror at the top of their lungs.
Agathan Knight: FOR THE GLORY OF AGATHAAAAAAAAAAA!.
In Putty, the Firework Imps shriek "INCOMING!" as they start to fire missiles.
Sokka initially tries to be this in the second episode, but gives up on it once he realizes he's no match for Zuko. After some training, he's shown to indulge in it from time to time. He also tried to do a sneak attack on Aang from behind...whilst screeching "SNEAK ATTAAACK!!!" at the top of his lungs. He is forcefully reminded of the negatives of this trope.
Sokka's attempt in the second episode turns a comical few moments into something less funny when one considers how much he's trying to emulate the warriors who left home, i.e. his dad Hakoda.
We also see the Southern Raiders all letting out a battle cry before attacking the Southern Water Tribe.
Parodied in, what else, Freakazoid!. Freak attempts a multi-step plan to subdue a giant snake that starts with him giving a "Conan Yell", then jumping on it and grappling it... before realizing he has no idea what to do next.
The infamous rolling, yipping "Rebel Yell" employed by Confederate soldiers during The American Civil War (not to be confused with the Texan yokel "Yee-haw!", by the way) was said to have chilled the blood of any Union troops that heard it. Scottish Highlanders and certain Native American tribes were also said to have employed similar-sounding yells in battle (and, since at least some Southerners had both Scottish Highlanders and Cherokees in their family trees, that last counts as a bit of Fridge Brilliance).
"Tenno heika Bannzzaaaiii!" or so the old Nipponese war cry goes (Literally, "a thousand years [of life] to the Emperor"). A harbinger of trouble for any ill-equipped, ill-fed and ill-led Chinese conscript low on ammunition - which was most of them, most of the time. Banzai charges were a perfectly valid tactic in China, as many partisans and warlord troops would break off and flee at the cry. It was not nearly so successful against professional Chinese troops, or Commonwealth and American soldiers when they got dragged into the war. Not because it was any less terrifying, but because they had decent numbers of machine guns and reliable supplies of ammunition for them. Also "Totsugeki!!" (which literally just means "charge!")
Kendo, a Japanese martial swordfighting art, utilizes kiai shouts before and during attacking, with the shouts before attack used to throw your enemy off-guard and help you concentrate yourself and the kiai during the hit to let others know that you are concentrating on your hit and are giving your best to hit it.
There is an informal practice of shouting as you attack in fencing.
A kiai turns you into a screaming warrior. Part of its intension is to add power to your attack and part of it is purely intimidation.
Most of the armies would scream while charging, be it something formal, like "banzai", "charge", or "Oo-rah," or something individual for each soldier, collapsing into incoherent roar, for exactly same reasons: intimidate and focus one-self for a high-speed dash towards the enemy. Not so common now, of course, since full-scale charge is rarely performed.
At least according to the Romans the native Britons would often scream at the top of their lungs when attacking. Combine this with spiked hair, blue warpaint and the fact that they were usually half again as tall as the Romans and you can see why they made them nervous. Not that much use against actual tactics, mind you...
It's human nature to freeze when scared. The US Army teaches their trainees to use the "battle cry" and scream before making an assault, as this helps to "unfreeze" the soldier in question.
Takahata101 of Team Four Star is prone to this, particularly during the Let's Plays.
The Imperial Russian, Soviet, and Russian Army's deep bass Oo-rah! would qualify, but with as less of a scream and more of a drawn-out 'urraaaaah' sound. Stolen from the Ottoman Turks, apparently; it means "strike to kill!" in Turkish. Definitely a symbol of the Russian infantry for centuries; German WWII vets said one of the creepiest sounds you could hear was that mournful howling sound as a Soviet attack went in, regardless of whether it was directed at you or not...
Germans also had a similar sounding war cry, "Hurrah!" Several German World War II vets noted that they occasionally mistook one for the other on the Eastern Front.
Chimpanzees. when an entire troop attacks, screeching at the top of their lungs, the effect is absolutely terrifying. Also deafening.
Tigers have an ultrasonic scream that even humans can hear from miles away. They never use it during hunting, because that kinda defeats the purpose. In fact, they only utilize this scream when fighting other tigers, capitalizing on the tiger's very sensitive hearing - it hurts them almost as much as the teeth and claws do.
