The Treue (German for "loyalty") Unit in Super Robot Wars Original Generation, and it's not just "coincidence" like many others; the unit is, for some reason, for females only. Note: these three are all Stuffed into the Fridge.
The titular Otome of Mai-Otome, although there is a Techno Babble explanation for their powers being exclusive to female virgins. While an Otome usually works alone, doing her Master's bidding, the Five Columns (who have no Master) are an actual team.
Fanon in regard to the Dirty Pair frequently implies, for reasons we can only guess at, that the entirety of the 3.W.A.'s field-agent personnel are female. It may have to do with the fact it was inspired by/named after an all-female Professional Wrestling association.
Integra, Accela, Sylvia and Celica make up the R.U.C.'s PROCEED squad in Solty Rei.
The three female pilots on the Nadesico worked as an Amazon Brigade (Amazon Flight, really) before joining the crew, and usually act as a unit while Akito or Akatsuki are off doing their own thing during the series. The ship's bridge crew is a couple of non-commissioned adjutants and one girly XO away from this trope as well.
Jail Scaglietti's "Numbers" in StrikerS count as well (no pun intended). Although that one had a rather disturbing justification: Scaglietti needed his minions to be female so that he could impregnate them with clones of himself.
The Red Tails Gang from Beelzebub are an all female gang of Japanese Delinquents known as the strongest ladies of Kanto, and for good reason too! Their leader Kunieda Aoi, nicknamed the Queen, is responsible for keeping the men's "grubby hands" off the other girls. Their weapons range from guns, to baseball bats, to bokken. And on one occasion, a ruler!
In Sound of the Skies, the Helvetian Army fields all-female tank crews, the main characters being the 1121st tank platoon.
In Sekirei, any group with multiple Sekirei is this by default. Most noteworthy are Minato's Battle Harem, Sanada of the West's Power Trio, and the Discipline Squad, while the other two major groups (the South and the East) don't function as units to the same degree. The first incarnation of the Discipline Squad remains legendary for their strength, as well as having been the one version to include The One Guy.
Mermaid Heel is a female-only guild in Fairy Tail.
In the Yu-Gi-Oh! franchise, many female duelists have either mostly female monsters. If not, they use monsters that make their decks look feminine.
Mai Kujaku is a prime example, who uses both Harpies and Amazoness monsters. The Harpies might be the Trope Codifier for the franchise, since they archetype has Taken a Level in Badass for several years and has become a strong meta archetype.
Anzu uses mostly female monsters or angelic creatures. The monster Maha Vailo, which she uses in the virtual world, has an Ambiguous Gender.
Averted with Rebecca. Her first deck had only a single female monster (Witch of the Black Forest). Her second deck contains only dragons.
Camp Siegfried uses a Valkyrie deck and even his three Permanent Spell Cards are based of goddesses.
Asuka's Cyber Girl deck is Dance Battler-themed, most notably ballerinas.
Rei's first deck plays it straight. Subverted later with her second and third deck.
Averted with Camula and her Zombie deck.
Tania uses an Amazoness Deck and she beats Misawa several times before she is defeated by Judai.
Subverted with Aki. She only has a few female looking monsters, but the majority of her decks are monstrously Plant-type monsters.
Also averted with Luka, whose deck is based of cute animals or fantasy-themed creatures.
Carly uses a Fortune Fairy deck, which is made of weak, cute fairies. After becoming a Dark Signer, her monsters evolve to Fortune Ladies, which become stronger for each level they have and their levels increase each turn.
Subverted with Misty, whose deck is mostly build of monstrously Reptile-type monsters, but she also has gorgons.
A short-lived offshoot of Marvel's The Avengers, the Lady Liberators; but they were secretly being manipulated by the Enchantress.
Another Marvel group, the Femizons, from a future militant Lady Land society. When that timeline was erased, a present-day misandrist named Superia tries to create her own Femizons a few centuries early by gathering supervillainesses and female Mad Scientists to repopulate the world, right after she sterilizes everyone else, of course.
The Star Sapphire Corps from Green Lantern. Subverted in the fact that the Star Sapphire's version of Ion or Parallax, Predator, is male.
The recently formed Sisterhood of Mutants in X-Men.
The Black Dahlias from The Order, who Veda described as "Tim Burton sponsors a women's golf team."
Katarina Dante's pirate crew and Monique le Fanu's vampires (who now presumably follow Lulu Romanov) in Nikolai Dante.
In the "X-Tinction Agenda" crossover storyline Uncanny X-Men books, artist Jim Lee depicted the law enforcement of Genosha as being mostly female and incredibly hot.
The The Man from U.N.C.L.E. comic book had an unrelated backup feature, Jet Dream. Gender-flipped Expies of Blackhawk, Jet and her international teammates Marlene, Petite, Cookie and (sigh) Ting-a-Ling were Hollywood Stunt-Girls who also moonlighted as a crack team of all-girl aviators, spies, and commandos.
Battlefields: Night Witches, by Garth Ennis, is a fictionalized account of the USSR's "Night Witches" (see Real Life, below) during World War II.
Sin City has the Old Town girls. They've teamed up a lot with the male protagonists but there are male-less Old Town stories out there. Also keep in mind that these girls are tough enough that both the cops and the mafia are afraid to mess with them.
The Airmaidens, the elite personal squadron of Valkyrie in Airboy.
In Astérix and the Secret Weapon, the Romans raise a legion of women to fight the indomitable Gauls, taking advantage of the Gaul's rule that they Wouldn't Hit a Girl. They do seem to have a problem understanding the words "order" and "discipline."
The 2013 (adjectiveless) X-Men comic will feature an all-female X-Men team: Storm, Rogue, Kitty Pryde, Rachel Summers, Psylocke and Jubilee (with Monet showing up at times). It also applies to the villains - Lady Deathstrike, Enchantress, Typhoid Mary, and Karima.
Rat Queens has this in the eponymous adventuring party; the rival party "The Peaches" are almost this but for Allan, their smidgen thief.
Literal amazons appear in the sequel to Zombies Vs Robots, which is named Zombies Vs. Robots Vs. Amazons.
In the Dynamite Entertainment Lady Rawhide mini-series, Lady Rawhide takes on a gang of female vigilantes called the Sisters of the White Rose, who were inspired by Lady Rawhide but use far bloodier methods.
Discussed and inverted in the MLP:FIM adult fic Xenophilia. Between the gender disproportion of Equestria and the matriarchal system resulting from the two immortal princesses, Men Are the Expendable Gender is inverted, along with many social norms. That means the buff pegasi and unicorns guarding Celestia are the local equivalent of Bodyguard Babes.
The Daughters of Manehatan from The God Empress Of Ponykind; the Western Rangers may qualify as well, since we haven't seen any colts serving that Legion.
A whole body of work has been presented about the Last Detail, the all-female combat unit introduced in Monstrous Regiment. This largely results in femslash about Polly Perks and the vampire female Maledicta, but all the fictions emphasise what a coherent, hard, fighting unit they are.
The new generation of female Assassins are also badass, either taken individually or working as teams. Lady T'Malia, Alice Band, Madame Deux-Epées, Remora Selachii, miss Smith-Rhodes and Jocasta Wiggs are the named Assassins in Pratchett's canon. Other fanfic writers have expanded on these characters and added new ones, such as Ruth N'Kweze, Joan Sanderson-Reeves and Davinia Bellamy. (For an example, see The Graduation Class.)
The Great Alicorn Hunt: Rarity's new branch of the Royal Guard, the Radiant Guard, is composed entirely of mares who look like models, but can throw weapons with pinpoint accuracy and toss a grown stallion across a room.
We never actually see them, but Zulu has a scene where Swiss mercenary Schiess, arguing with two overly confident Welsh soldiers, mentions that the Zulu leader Cetawayo has a regiment of female warriors called "Ripen at Noon". One of the Welsh soldiers comments that "that's pretty".
October (Red October, that is) portrays the "Women's Battalion of Death", an all-female unit that was part of the doomed defense of the Winter Palace against the Bolsheviks. See Real Life below.
The Sisterhood of Kira Earta, an order of warrior priestesses in Swordcraft.
In the Star WarsExpanded Universe we have the Mistryl Shadow Guard, a group of whip-wielding mercenaries from a doomed civilization, and the Hapes Consortium, an interstellar cluster of Amazons whose (formidable) army and navy was solely composed of females.
In The Firebrand, Marion Zimmer Bradley's retelling of The Iliad from the perspective of Kassandra, we have... the original Amazons. By the end of the book, they more or less die out, logical with the feminist bent of the novel and the way that the cult of patriarchy was sweeping the nation.
Bradley's Darkover has the Sisterhood of the Sword; their successors, the Free Amazons, are less of an example, as while they are all trained to fight they don't exclusively work as soldiers.
In Dune the Bene Gesserit can fight with nearly superhuman capability if necessary, and Heretics of Dune introduces the Honored Matres. Leto II justifies this trope when he forms the Fish-Speakers in God-Emperor of Dune: he believes their maternal instinct will prevent them from succumbing to bloodlust or quests for power, and they're a temporary army since they're all about him, so they'll lack a unifying force once he dies. It's all part of his Golden Path for humanity.
The Discworld novel Monstrous Regiment features a squad consisting entirely of Sweet Polly Olivers. The first clue is right there in the title: John Knox once wrote a pamphlet called "The First Blast Of The Trumpet Against The Monstrous Regiment Of Women".
Isaac Asimov's short story "Shah Guido G." features an all-female police force known as the Waves. However this really had nothing to do with the plot, being part of a clumsy and long-drawn-out build up to a punning punchline.
The Reynard Cycle: The militaristic Calvarians regularly field companies of these. They appear to be treated as equals of the men.
By Defender of the Crown, a significant portion of Reynard's army is made up of women, with Rukenaw in command.
In The Stainless Steel Rat's Revenge Special Corps agent James Bolivar "Slippery Jim" DiGriz lands on a planet once run by women (until they were usurped by a male revolutionary party working in cahoots with galactic invaders). He teams up with the resistance – former members of the military who are of course fit, shapely young amazons— much to the annoyance of Jim's lethally-armed and dangerous wife.
Isobelle Carmody's The Legendsong Saga has the myrmidons; a community of female fighters based on the island of Myrdmoor, whose primary duty is to protect the soulweavers while away from their home on Darkfall. Their preferred fighting method is a form of martial arts, sometimes accompanied by a short javelin.
The Mord-Sith from the Sword of Truth, who are the sworn protectors of Lord Rahl, as well as his expert torturers. They perform... other services for him, they act as his bodyguard, are capable of beating up squads of elite soldiers without breaking a sweat, have a magical torture device / weapon / awkward phallus thing called an Agiel, they're made via a truly horrifying Break the Cutie indoctrination process, are probably the second most feared thing in all of D'Hara, only behind the Lord Rahl himself... oh and they can capture your magic and use it to torture you. They've driven one member of the main cast insane.
The Longwing dragon captains in the Temeraire series could be a sort of Amazon Brigade — Longwings almost exclusively select female captains (it is implied that on occasion one will accept a male grudgingly, but none have been shown yet). In China several centuries before the events in the books, women were permitted to serve as combat dragon riders by Imperial Decree after a Sweet Polly Oliverenlisted to spare her fatherand stopped an invasion after bonding with a dragon. Between conscription and the willingness of families to get rid of daughters, by the time Cpt. Laurence and Temeraire arrive the Chinese government had long since thrown up their hands and made their Dragon Corps an exclusive female preserve.
Percy Jackson and the Olympians has the hunters of Artemis, a group of girls that travel with the goddess Artemis and are allowed to live without aging as long as they remain maidens for ever. They happen to be extremely handy with a bow, and are strong fighters all around. The Heroes of Olympus also reveals that the Amazons themselves are still in business, running Amazon.com.
The Queens' Wing can be a pretty effective Thread-fighting force in the Dragonriders of Pern novels, particularly once they caught on to how easily a queen dragon can boss around any other color.
Thandi Palane's self-styled Amazons (descendants of genetically engineered Ukranian supersoldiers) in the Honor Harrington universe.
Much like in Ursula Vernon's webcomic Digger, her Black Dogs series contains a race of matriarchal hyena people. Their appearance is more brief and their role much less pivotal, but from what is seen of them, their warriors and hunters are all female. It is also observed by the protagonist that the females are larger and more physically intimidating than the males.
In Sewer, Gas & Electric, a female Royal Navy officer averted an assassination attempt and, in return, asked Queen Elizabeth II for command of a submarine. When the navy brass told Her Majesty that having a woman take charge of a sub was unthinkable due to conditions on board, Her Majesty got peeved; four years later, the H.M.S. City of Women was launched with an all-female crew.
A rare non-Fantasy or Sci-fi example: thriller writer Brad Thor created a "detachment" of all-female Delta Force members for his most recent Scot Harvath novel Foreign Influence, which spawned the sequel/spinoff The Athena Project.
Neal Stephenson's Science Fiction novel The Diamond Age has Nell's "sisters", or "Mouse Amy", a group of soldiers/engineers/political leaders that finally becomes a new sovereign.
The soldiers of the Hames in Jane Yolen's Great Alta Saga. Before the invasion, they were among the most honored warriors in the Dales, and not a male in sight.
David Weber's War God series has a couple of different examples. The most detailed example are the Sothoii War Maids. Free towns administered by women in the very patriarchal Sothoii society they are required to supply levies in times of war under the Kingdom's feudal military structure and by tradition they field all female fighting forces. Considered outcasts by Sothoii society as a whole but supported strongly by the Wind Riders, the elite of the Sothoii military.
The Amazon Legion focuses on one of these, with particular attention given to how to maximize the effectiveness of the women in it given the general physical limitations compared to men.
In the Aubrey-Maturin novel The Far Side of the World, Jack and Stephen are rescued/taken prisoner by the all-female crew of a Polynesian twin-hulled craft. They also have an extreme case of Does Not Like Men, apparently castrating their male captives as a matter of course.
The Marvelous Land of Oz features Jinjur's army. A revolutionary army composed entirely of young girls dressed in World War 1 era uniforms. This being one of the Oz books, they're about as deadly of a fighting force as a kindle of kittens. They find early success against the Emerald City's army, an old man who Wouldn't Hit a Girl, but are in for a nasty surprise when Glinda brings in her own all-female army who actually know what they're doing.
Sisterhood Series by Fern Michaels: The Sisters, Sisterhood, or Vigilantes (whatever you like to call them) can be considered this - as long as you don't include Charles Martin and the Big Five or the Five Musketeers. The last book Home Free subverts this trope by having the Vigilantes recruit male members into their ranks at the end.
The eponymous Bunch in The Bad Bunch by J.T. Edson; an all-female gang of outlaws as dangerous and ruthless as any men.
The qawHaq'hoch, in the Star Trek: Voyager Relaunch, a Klingon cult consisting of female warriors only. Interestingly, it's never explained why they only accept females. Possibly it's "just tradition" - but it's one they're quite serious about. They draw attention to their status as an Amazon Brigade by using a symbol for birth (Ie., an aspect of life exclusive to women) as the glyph signifying the correct tunnel to their headquarters.
Harry Potter has the Holyhead Harpies, an all female Quidditch team.
Legacy of the Dragokin: The Kthonian Knights are supposed to be this because they hate men and wanted to kill all of them but Jihadain let Ravage join because he's Fury's protective big brother and she wants him to join.
My Dark And Fearsome Queen: The president of the high school drama club turns out to be an evil queen exiled from an alternate dimension, and all the girls in the club turn out to be her guards.
Though almost all Giants in the Chronicles of Thomas Covenant are badass, as a whole they tend to view physical violence as an extremely distasteful last resort (albeit one they're very good at), and as a result have few professional warriors. That said, those professional warriors (the Swordmainnir) are almost entirely women (it's not unheard of for a male Giant to become a Swordmain, but it's extremely uncommon), and they're very good at what they do. This is especially clear in the Last Chronicles when an entire, all female, detachment of Swordmainnir show up and get to show off exactly what they can do.
Subverted in the Ken Follett novel Jackdaws. The eponymous Strategic Operations Executive saboteur team was originally planned to be all female, so that they could disguise themselves as cleaning women so as to infiltrate a critical German telephone exchange building in occupied France. The problem is that the team leader, Flick Clairet, had only a couple of days to recruit the team, and could not find a female telephone engineer in Britain who also spoke fluent French, so she ended up recruiting "Greta," a male transvestite instead.
The Slayers after season 7 of Buffy the Vampire Slayer. Every slayer is female and all of them are walking anti-vampire weapons. After the events of season eight Kennedy didn't just sit on her hands. She creates Deepscan, giving Slayers with no further purpose a job in bodyguard work.
One episode of Stargate Atlantis featured an Amazon Brigade providing most of the muscle. Colonel Sheppard and Dr. Beckett were thoroughly delighted to be working with them.
Stargate SG-1 has the Hak'tyl, a Jaffa tribe hiding from the Goa'uld Moloch.
Star Trek: Enterprise was the first to reveal that the Orion women, far from being the slaves portrayed in the other series, actually control their civilization with a male-attracting pheromone that gives other women headaches. The only one unaffected by them is Trip.
A villainous example were Saladin's assassins in Robin Hood, a squad of women who were sent to kill Prince Malik.
Sir Arthur Conan Doyle's The Lost World: The episode "Amazons" had a society of female warriors, whom Veronica has a prior history with. They are actually quite pleasant to the men at first, then they are held captive.
Emilie Autumn's riot grrl-esque band The Bloody Crumpets (or at least their stage personas). Even Aprella. Hell, their catchprase is "Fight like a girl!" As a phrase of empowerment, that is.
Klymaxx is also this.
Myths & Religion
The White Tights of urban legend, a group of blonde, white-cladsniper women with a hate-on for the Russians. Allegedly formed of women from Eastern European countries such as Estonia and Latvia, where hating Russia is a national pastime. According to rumors, they fought in Chechnya on the Separatist side, and were brutalized by Federal army grunts in case of capture (every Federal soldier had a friend of a friend who allegedly captured, raped and horrifically, painfully slaughtered a "white tight").
In Chinese folklore, the widows of the Yang generals during the Song Dynasty. When most of the Yang menfolk were killed defending a fort from Liao invaders, the women of the clan took up arms to confront the Liao army. This has been dramatised in films such as The Fourteen Amazons and The Legendary Amazons.
Although the Valkyries of Norse Mythology were primarily focused on collecting the dead, there were plenty of attestations of the female bands fearlessly engaging in battle.
Space 1889 Very surprisingly there is such a unit, a human unit to boot, in this Victorian role-playing game... ...and its historical. Soldier's Companion mentions that Company A of the 62nd St. John's Fusiliers of New Brunswick, Canada stationed in Syrtis Major, better known as the Amazonians, is all female except for the commanding captain. Averted in that it is not an elite unit. Soldier's Companion claims this unit existed historically. It is also mentioned in Transactions of Royal Martian Geographical Society part 1.
Imperial Guard regiments are almost uniformly single-sex units, and according to the Ciaphas Cain novels about 10% of the Guard's forces are all-female regiments. Mixed units do exist, but are usually the result of depleted regiments being combined together, as was the case in Cain's own Valhallan 597th as well as the Tanith First and Only. The gender segregation is mainly for practical reasons, as shown when Cain has to deal with increased fraternization between troopers and some unforeseen complications.
The Dark Eldar's Wych Cult is made up of elite warriors who help capture prisoners during slave raids, then fight the captives in gladiatorial combat for the Dark Eldar's bloody amusement. Wyches take pride in their appearance and emphasize spectacle during their arena matches, so they do battle against the likes of Space Marines and Tyranid Warriors while wearing anti-clothing. Males are allowed to join the cult, but they never manage to progress far in it - they simply lack the proper "style and poise" to become a true champion.
The Sisters of Silence were composed entirely of women that were Blanks. In the 41st Millenium, they crew the Inquisition's Black Ships and manage rogue psykers rather than engage in direct combat.
The Dark Elves provide two examples. Witch Elves are an all-female cult of attractive, lethal fighters in chainmail bikinis, who serve a god of murder, indulge in combat drugs, and bathe in blood to preserve their beauty. Dark Elf Sorceresses also qualify due to a prophecy that a male sorcerer would kill their Witch-King, who quite naturally banned men from practicing magic. There are male sorcerers, but they keep their heads very far down.
Dragon Dice has an entire playable race of Amazons. The only race in the setting created directly and solely by the male deity, they can be played as either an entire army of Amazons, or as an elite maneuver/ranged combat unit in a larger force.
In Rifts, Free Quebec has mastered the creation of the uber-powerful Glitter Boy powered armour. Female pilots lobbied for years to get their own distinctive style of armour. Enter the Glitter Girl recon/special forces unit. More dangerous than the male variant due to the pilots being older and more experienced. Notable squads inclued the Harlots, the Harpies, the Vixens, and the Riot Girls. The Splugorth also make use of a bio-engineered race of slave-warriors called the Altarains, or else "The Blind Warrior-Women of Splugorth" who are a One-Gender Race.
Werewolf: The Apocalypse had the Black Furies, a tribe made up entirely of female Garou who worshipped Artemis as an aspect of Gaia. Of course they'd associate with men for production of new children, but male offspring were passed on to other tribes. There are male Black Furies, however; Metis (deformed children of werewolf-werewolf matings) born to Black Fury mothers are accepted into the tribe regardless of their gender.
The Sisters of Mercy from the Feng Shui supplement "Glimpse of the Abyss" are a convent of Nuns With Guns based in the Netherworld who hunt down and kill those whom their Mother Superior deems to be deserving of the respite of death from the suffering the Sisters believe that life is. Of course, those whose names end up on the Rolls of Mercy and are targeted for "deliverance" often aren't so keen on dying. Also from "Glimpse of the Abyss" are the Shiva Squadron, a band of distimed eight-armed warrior women who have made it their mission to hunt demons.
Legend of the Five Rings has two examples in the matriarcal Utaku and Matsu families. The Utaku family (formerly known as the Otaku family) has the Shiotome, or Battle Maidens, an elite unit of shock troops that ride into battle on horses the size of Clydesdales. The Matsu family's elite Lion's Pride is an all-female unit of samurai women that specializes in finding and killing the enemy general and his command staff.
Exalted has the Brides of Ahlat, the Southern God of War. Completely female, sworn to remain virgins, and symbolically wed to Ahlat himself. They're consider to be Elite troops and thus not to be messed with.
Exalted also has the Tya, a group of women in the West who reject the usual gender roles for the region to take on male ones-which is more than symbolic, as the ritual wards away the spiteful goddesses known as the storm mothers (they hate any woman prettier then they are, which includes everyone that is not a storm mother). They are treated in society more as men than women, actually.
In 2nd Edition Dungeons & Dragons, several of the "Complete Class" supplements included an Amazon character kit.
Mage Knight included a subset of Amazon figures in one of its more Steam Punk factions, the Black Powder Rebels. They weren't necessarily more powerful than any other group or faction (except for the Amazon Draconum, which was borderline broken.)
In Mutant Chronicles, at least three factions have Amazon Brigades: Bauhaus has Etoiles Mortant, Imperial has Mourning Wolves and The Brotherhood has Valkyries and Vestals. Mishima was supposed to have an elite unit of female warriors, the Kikigomae Sohei, as well, but Publisher Existence Failure caused them to be limited only to a concept drawing and a mention in the rulebook for Warzone: Universe Under Siege as no figures were produced.
Dungeons & Dragons: The Tome of Battle has lots of fluff about secret organizations of Walkers of the Sublime Way. One of which is the 80 Empresses.
The Amazones of Bloodlust, called Sekekers, are used to mutilate themself and are thus quite ugly. However, some beautiful young girls form a elite unit called the Chrysalides, and are trained to fight half-naked.
Shadowrun has the all-female street gang Desolation Angels that are active in many American cities. The gang is known to hunt bug spirits with great enthusiasm for some reason. The reason is simple: they are Mantis spirit hosts.
Legends Of The Wulin has two: The Resplendent Phoenix Society, who seek to embody feminine perfection, and the Blood Wind Cult, an all-female sect of assassins.
The various incarnations of the "Women's Team". Its ranks include: King, Mai Shiranui, Yuri Sakazaki, Kasumi Todo, Chizuru Kagura, Li Xiangfei, Hinako Shinjou, Blue Mary Ryan and May Lee.
In KOF 2003 Athena Asamiya, Hinako and Malin had their own all-girls group, the "High School Girls Team".
Similarly, KOF 2002: Unlimited Match (a remake of the original KOF 2002) gave us two other all-girls team: the "Pretty Girls Team" (Xiangfei, Hinako and May-Lee, who was a member of the original Women's Team in the first 2002) and the enemy-only NESTS team (Kula, Foxy and Diana)
The Night Elves' military, the Sentinels, is comprised solely of women because the race's men study druidism and spend centuries at a time asleep in the Emerald Dream. Over the course of the campaign male Night Elves join the battle, but only as support casters (at least until the Druids of the Claw shapeshift). By World of Warcraft the gender divide is eased so that Night Elven females can become druids and men can become fighters, but the overwhelming majority of Sentinels are still women, while there is only a single male priest of Elune seen in-game. As probably an inverted reference to this, the Blood Elf guards are all male.
Fireemblem Jugdral: Mahnya, Ferry, Deetvar and Pamela aka the Angelic Knights of Silessa (first generation, and actually Deetvar and Pamela are enemy units and Mahnya dies); also Maybell, Meng and Bleg (second generation, another villainous example)
Fire Emblem Elibe: Shanna, Thite and Juno (Sword of Seals); Florina, Fiora and Farina (Blazing Sword)
Fire Emblem Awakening: Cordelia, Sumia and Cynthia. Unusual since Cynthia is actually Sumia's Kid from the Future. Optionally, you can reclass some female characters as Pegasus Knights and get others via DLC.
In Final Fantasy IX, Alexandria's army consists almost entirely of women. The only males are the Knights of Pluto, a squad consisting of a mere 9 men, including playable character Steiner, who serves as their captain.
The military of the city of Troia in Final Fantasy IV likewise consisted entirely of women.
The Mosu Ninja from Shinobido are composed only by kunoichi.
Xenogears has Dominia's all-girl robot pilot squad.
Luna's subordinates in Soul Calibur 3's Chronicles of The Sword, the Klessirpemdo, are a quartet of elementally-themed female minions: Lupi (Fires of Hell), Heal-Do (Water of Origin), Elua (Wind of Creation) and Aege (Earth of Foundation). Their leader Luna is probably meant to be Spirit/Aether or something.
Unreal II: The Awakening features such a brigade in the form of the Liandri Angels, an all-female "mercenary" cyborg squadrons, the game's toughest Mooks. An in-game dialogue maintains that females are naturally ruthless and that that has been the reason behind the creation of these squadrons.
Diablo II starts the player out in the Rogues' camp (a reference to the female-only Rogue class from original Diablo). Everyone permanently living there is female, from the blacksmith Charsi to the matronly high priestess Akara to the guard captain Kashya. They're staying in the camp because they had been evicted from their monastery after Diablo's minions took over and mind-controlled half their numbers, whom you fight throughout Act I, and who are also all female.
The Aeon military in Supreme Commander comes very close-game background states that Aeon women are just plain better at battlefield command, with very few males qualifying for command. Possibly a coincidence, but the foremost commanders of the UEF and Cybrans are women as well.
In the first Knights of the Old Republic, an away team composed of a female player character plus either Bastila Shan, Juhani or Mission Vao. In the second, a female player character plus either Mira, Kreia or Visas Marr (especially if you have progressed far enough to make Mira a Jedi).
The asari are a One-Gender Race of women, and due to their extremely long lifespans (upwards of a thousand years) asari commandos train for a hundred years before they go on active duty. In addition, the asari are also natural biotics. The warrior turian race (where military service is the entire society and military service is directly responsible for citizenship) have a saying: "The asari huntresses are the best warriors in the galaxy. It's a good thing there aren't that many of them."
Additionally, a field squad composed of a female Commander Shepard and any two of Ashley Williams, Tali'Zorah nar Rayya, or Liara T'Soni also qualifies as an Amazon Brigade, particularly at higher levels. And in the sequel, Female Shepard with Jack, Kasumi Goto, Miranda Lawson, Samara, Tali, Morinth, and Liara T'Soni (in DLC) counts.
And in the third game, Female Shepard with Ashley, Tali, Liara and EDI, or the Omega DLC squadmates.
In Mass Effect 1, should you refuse to recruit Garrus, kill Wrex and sacrifice Kaidan on Virmire as a Femshep, an Amazon Brigade squad will be your only option.
The Valkyries, an army of ace pilots and shock troopers comprised entirely of female aliens. Despite the name, male v ersions exist but, according to a piece of Galactic Trivia, were banished after failing to ask for directions during their pilgrimage after their home colony was decimated by a supernova.
The Galactic Rangers are apparently all female as well, although whether that's correct or simply the squad leader unnecessarily taking the Mickey isn't explained.
Project Justice has the Seijyun High trio of Akira, Yurika and Zaki. Closer to the definition of this trope is Zaki's gang, the Ladies Team, though a good number of the gang's members may not meet the "be at least moderately attractive" description.
In Baldur's Gate II: Throne Of Bhaal, one of the three guardians for the final seal is an entirely female group composed of Y'tossi (a marilith), Nalmissra (a succubus), The Hive Mother (a beholder), Amerilis Zauvwir (a drow cleric), The Huntress (an archer) and Xei Win Toh (presumably a kensai).
Also possible for your own party: in BG1 you have a female PC and (depending on your alignment) any combination of Alora, Viconia, Dynaheir, Imoen, Jaheira, Branwen, Faldorn, Shar-Teel, Skie and Safana. BG2, ToB and the new Enhanced Editions feature the return of Imoen, Viconia and Jaheira, along with new characters Aerie, Nalia, Mazzy, Hexxat and Neera.
Interior Union in Armored Core, every one of the Lynxes for hire is a women, and unlike Bernard And Felix, more than willing to let you use them as consorts.
In Neverwinter Nights 2 it's possible to create a balanced all-female team using a female Knight-Captain built as a tank, Qara the sorceress, Neeshka the rogue, and Elanee the druid. Act II adds Shandra Jerro as a guest star fighter, and the githzerai cleric Zhjaeve. Even easier in the second expansion, Storm of Zehir, which lets you handcraft your own party.
Sakura Wars. This is the entire point of this Dating Sim / Tactical RPG series. With a dash of That One Guy thrown in as your player avatar (Ogami in the first four games, and Shinjiro in the fifth game.) Your party's effectiveness in battle is dependent on how strong your bonds with your Amazon Brigade are... in addition to how well they get along with one another.
You get an achievement for using an all-female squad in the XCOM: Enemy Unknown remake. Otherwise, there's absolutely no difference (e.g. a female Heavy can carry a heavy plasma gun and a rocket launcher just as easily as a male Heavy, despite not looking the part).
The mmorpg game Scarlet Blade emphasizes in this, as the game focuses on genetically enhanced females, and there are no male playable classes.
The player's main force in Sunrider is an all-female Mecha squadron.
The Latin Junta from March Of War has literal units of Amazonian warrior women in their army.
Mount & Blade has the Sword Sisters unit, female knights/heavy cavalry clad in plate armor, wielding swords and crossbows. They are notoriously hard to acquire (you have to rescue or press-gang a lot of unskilled peasant women and give them someTraining from Hell).
In Tales of Symphonia Raine's title of Crimson Rose is earned by putting her along with the other three playable women characters in your active party. There's also the Distaff Counterpart title of Testosterone for Regal by putting him with the four other playable male characters.
The eponymous Huntress team in RWBY. They're still in training, but it's clear that no sane person would mess with them.
In El Goonish Shive, Ellen, Grace, and Nanase form a temporary Amazon Brigade during the Painted Black arc.
The Amazons of Chasing the Sunset. Their foremothers were ordinary women who took up combat to save themselves: by the time we meet them in the comic, they are blue-skinned warriors who reproduce asexually.
An internet offshoot of Marvel UK's Warheads series, Loose Cannons tells the tale of an experimental all-female group of Warheads (paramilitary units sent through spacetime wormholes to gather technology and magical artifacts for the Corrupt Corporate Executive leaders of the sinister MysTech; think Stargate SG-1 as mercenary raiders hired by a cabal of evil sorcerers) called the Virago Troop— who bring back more than they bargain for from an After the End future.
Haven's Guard in Earthsong form an Amazon Brigade, including The One Guy, Zaebos. And one Hermaphrodite Tengu...
Outsider has the Loroi, a species of space elves with an all-female military. Justified, since only one in eight Loroi are born male, which they consider a basic adaptation for a warrior species, since it allows them to create some massive population booms where necessary, or avoid overpopulation by restricting access to males. Further justified by the fact that Loroi females are actually the bigger and stronger members of the species. The males are child-sized.
Illyra, Elysia, and Occela form the basis of a budding Amazon Brigade in Rumors of War. Given that the setting is based on Greek Mythology, one or more of them may actually be Amazons.
Though not a brigade specifically, the female cast members of Something Positive are both more violent and most of the time, stronger than the male cast members (although how much the male members are willing to fight in general may have something to do with it). The basic rules seems to be that if somebody has a pair of breasts and is reasonably intelligent, she can probably kick your ass.
In The Gamers Alliance, the army of the Eastern Horde consists of demonesses who specialize in fast and agile combat as well as deceiving and seducing males from their own race and other races to make them their willing slaves.
Team Kimba of the Whateley Universe is really close, considering that their one 'boy' was born a girl named Hannah. The Whateley Academy Martial Arts Cheerleaders are all-girl but not tough enough to be a true Amazon Brigade.
Practically the entirety of The Black Legion of the Dark Lord Sketch Melkor. They're run by a girl in high school, Sketch, and the majority of the Legion consists of action girls that make blood sacrifices and invaded Canada. There's also a genderqueer balrog warlord, and the only three guys in the Legion are self-proclaimed nerds that participate less than everyone else in conquests.
Avatar: The Last Airbender has no shortage of strong, able-bodied, females. So it's hardly any surprise that there's two examples of the trope:
The first is the Kyoshi Warriors. which was created in honor of Avatar Kyoshinote sometime before she separated their island from the mainland to prevent a war with Chin the Conquerer. Their group is lead by Suki, and is responsible for protecting the island from intruders - just as Kyoshi did, long ago.
The Winx Club are six fairies who face evil witches, wizards, and monsters on a daily basis, and beat them all up spectacularly.
The three titular characters from Totally Spies! (WHOOP doesn't seem to have an all-female requirement for spies, but the most prominent recurring character who was a member was Britney, and Mandy was also a member briefly. The trio does report to Jerry, a male superior.)
The Amazons (surprise, surprise) in Motorcity, with their leader Foxy. Claire briefly teams up with them, and Julie pretends to be interested in joining.
In comparison to the previousgenerations, the main characters of My Little Pony: Friendship Is Magic are prepared to get into a fight and handle themselves well if they have to. The G1 ponies seem to be helpless without Megan, and the G3 ponies had virtually no conflict to begin with. The male fans of the show seem to like it this way too, to the point that if someone refers to the main characters as the "Mane 7" and includes poor Spike, it tends to cause drama.
North Korea fields a number of army regiments that are entirely comprised of women. They more commonly seen marching in propaganda parades, but reports and photos of female units actively patrolling the DMZ are not unheard of.
Not to mention the famous Dahomey Amazons, or Mino, who composed a third of the Dahomeyan Army in the 19th Century. Fanatically dedicated and intensively trained, they were nearly unbeatable for three and a half centuries, until the invention of the machine gun made industry more important in war than bravery.
There were three all-female combat Soviet Air Force units in World War II, which together flew a total of 30,000 combat sorties, produced 30 Heroes of the Soviet Union (the highest honour available) and 2 fighter aces (the only recorded female aces in history). The most famous of these was the 588th Night Bomber Regiment, nicknamed the Night Witches by the Germans. Not only did they fly over 23,000 sorties and is said to have dropped 3,000 tons of bombs, it was also the most highly-decorated unit in the Soviet Air Force at the time, receiving 23 Heroes of the Soviet Union awards. Not only that, they flew horrifically out of date, wood and canvas bi-plane bombers originally constructed for training and crop dusting - and these planes proved excellently suited for precision night bombing, the reason this regiment was called Night Witches. Weak engine means a quiet engine, plane designed for trainees must have a low stalling speed, reducing noise even more, and low speed gives you an excellent bombing accuracy. Oh and they almost always made their runs without parachutes because they would weigh down the planes too much.
The Soviets also fielded several all-female anti-aircraft regiments. Most of these, however, were completely wiped out when deployed against infantry in the Red Army's desperate attempts to stall the German advance.
There were also numerous female Soviet snipers (one, Lyudmila Pavlicenko got 309 confirmed kills before being pulled off the front line and used for propaganda purposes), and occasionally tank crews. However, both are cases of desperation in a way; the Soviets mobilized almost totally to repel the Germans.
Lyudmila Pavlicenko was so awesome that Woody Guthrie actually wrote a song about her shooting Germans, she was that cool.
The militsiya police during and directly after WWII. Soviet police had to recruit amazon brigades, because all the men were busy on the frontlines.
During World War I there was a battalion made up entirely of women, led by a woman named Maria Bochkareva, who personally petitioned the Czar to be allowed to serve in the Russian Army to escape her abusive husband. Towards the end of the war, she was put in charge of the Women's Battalion of Death. It was something of a publicity stunt to try and raise morale in the Russian Army. It failed, and about eight months after they were formed Lenin overthrew the Russian Provincial Government and the rest is history.
The Provisional Government planned to recruit several more such units, including the awesomely named Women's Black Hussars of Death Squadron. None had seen combat when the Bolsheviks took over.
Some members of the Women's Battalion of Death were part of the last-ditch defense of the Winter Palace against the Bolsheviks during Red October.
During the Russo-Japanese War there was an all-woman cavalry regement. The officers were daughters of the country nobility who from hunting could ride and shoot as well as their brothers; the enlisted women were recruited from a Central Asian tribe with a strong Amazonian tradition.
The United States Marine Corps developed the "Lioness Program" for use in Iraq and Afghanistan. Lioness is an all-female team meant to conduct culturally-sensitive searches, but in practice have done much more. The Lionesses have proven extremely useful for building rapport with the locals and gathering intelligence. (And should it come to that, "Every Marine is a Rifleman," even if she's not a man.)
Women in ancient Iranian cultures, such as the Scythians, the Sarmatians, and even the Persians, frequently fought alongside the men. Archaeologists have found many tombs where women received a warrior's burial.
The Women Guard of the Reds in the Finnish Civil War 1918. Inspiring both awe and admiration on the White side (some Whites compared them as "she-wolves" while others as "Northern Amazons" as they managed to repulse a German assault unit in combat), they nevertheless inspired the victorious Whites to found the Lotta Svärd women's army auxiliary organization. Women were finally allowed to serve in all branches of the armed forces in 1992.
Sun Tzu earned his reputation by forming one, allegedly. Before he was a famed strategist, he was tasked to turn 180 concubines into soldiers.
During the Franco-Prussian War of 1870-1871, the feminist and socialist leader Louise Michel organized a women's complement to the Eighteenth Arrondissement Vigilance Committee, essentially a citizen militia to defend Paris.
The Amazon River was so named because one of the explorers reported encountering a tribe of warrior women there.
The Kurdish peshmerga forces are already about 40% women, but for the struggle against the Islamic State in Iraq and Syria, they've recently been fielding all-female formations up to 500 fighters strong as an extra "fuck you" to the violently patriarchal religious fundamentalists. It's believed that the ISIS fighters fear they won't go to heaven if a woman kicks them from this mortal coil, and whether or not this is true, it's helped boost the Kurds' morale - and all the women in uniform has helped peshmerga recruitment, too.
