Every Clone Legion, Corps, Battalion and Company Explained

The Grand Army of the Republic started with 200,000 clone troopers ready and a million more on the way, every one of them grown from the genetic template of the bounty hunter Jango Fett. Tens of thousands went into the First Battle of Geonosis against the Separatist droid army, the Senate handed Palpatine authority over military affairs, and within weeks the fighting had spread from the Outer Rim all the way back to Coruscant. That army was not one mass of identical soldiers. It was a nested structure of corps, legions, battalions and companies, each with its own commanders, armor markings and battle record. This page works through every named unit that has appeared across the films, shows, games, comics and books, in both canon and Legends. (Attack of the Clones; Revenge of the Sith; The Clone Wars, "Rising Malevolence")

Clone trooper corps#

Continuity: canon and Legends.

The largest formation covered here. A corps was made up of four legions, totaling around 36,000 soldiers, and was led by a Jedi General alongside a clone Marshal Commander. (Star Wars: Complete Locations)

21st Nova Corps#

Far better known as the Galactic Marines. Led by clone Marshal Commander Bacara and Jedi Master Ki-Adi-Mundi. Clones assigned to the 21st had a reputation for discipline and were trained to operate in harsh, hostile environments, which is why they wore specialized armor. Their most notable deployment was the Mygeeto campaign. (Revenge of the Sith; The Clone Wars, "Old Friends Not Forgotten"; Star Wars: Complete Locations)

7th Sky Corps#

Led by clone Marshal Commander Cody and Jedi Master Obi-Wan Kenobi. The 212th Attack Battalion sat inside the 7th Sky Corps, and both wore armor with orange markings. Key engagements include Christophsis, Ryloth, the First Battle of Felucia, the Second Battle of Geonosis, Umbara and Utapau. (Star Wars: The Clone Wars (film); The Clone Wars, "Innocents of Ryloth"; "Landing at Point Rain"; Revenge of the Sith; Star Wars Battlefront II (2017))

91st Mobile Reconnaissance Corps#

Led at various points by Jedi Generals Mace Windu, Adi Gallia, Oppo Rancisis and Stass Allie, with Clone Commander Ponds and Clone Marshal Commander Neyo as their seconds. Trained for mobile warfare and reconnaissance, the 91st was a smaller and more maneuverable corps, frequently sent ahead to scout and secure passage for heavier formations. Ryloth, Malastare and Saleucami were among its most significant campaigns. (The Clone Wars, "Liberty on Ryloth"; "The Zillo Beast"; Revenge of the Sith; Star Wars Battlefront II (2017))

327th Star Corps#

Under clone Marshal Commander Bly and Jedi General Aayla Secura. The 7th Legion was part of the 327th. Beyond the distinctive yellow insignia on their armor, pauldrons and kamas were issued to the corps' higher ranking infantry. The Battle of Quell, the Siege of Saleucami and the Battle of Felucia were the corps' most significant engagements. (The Clone Wars, "Jedi Crash"; Revenge of the Sith; Star Wars Battlefront II (2017))

41st Elite Corps#

Commanded by Jedi General Luminara Unduli and Commander Gree, with subunits including the 41st Scout Battalion and Green Company. During the defense of Kashyyyk, Jedi General Yoda supported Unduli and Gree in command. The 41st was a corps in its own right but was organized as part of the 9th Assault Corps, which Unduli also led and which wore the same armor. Color schemes varied considerably across both formations, with green and gray markings chosen to suit the terrain, and specialized camouflage armor issued for Kashyyyk. They also fought at the Second Battle of Geonosis and the Battle of Coruscant. (The Clone Wars, "Cloak of Darkness"; "Landing at Point Rain"; Revenge of the Sith; Star Wars Battlefront II (2017))

87th Sentinel Corps#

Continuity: canon.

Marked out by the maroon markings on their armor. Because of their proficiency in urban defense tactics they were regularly dispatched to Republic cities at risk of falling under Separatist control. Little more than that is recorded about them. (Star Wars Battlefront II (2017))

416th Star Corps#

Continuity: Legends.

Led by Jedi General K'Kruhk. They are known to have fought at the defense of Teyr, where much of the unit was wiped out. Almost nothing else about them survives. (Shatterpoint)

Clone law enforcement units#

Continuity: canon and Legends.

These formations did not belong to any single corps or legion. (The Clone Wars, "Hostage Crisis"; "The Unknown")

Coruscant Guard#

A division of elite shock troopers who served as a military police force and guarded the Republic's capital world. They were also occasionally assigned to support diplomatic missions off world. Clone Commander Fox, known for his intense loyalty to the Republic, was the Guard's lead commander, with Commander Thire, Commander Stone and Commander Thorn leading units within it. Their crimson armor markings made them one of the more intimidating sights of the war. After the Galactic Empire was declared they carried on as a security unit on Coruscant, now with the added job of enforcing the rule of Emperor Palpatine. (Star Wars: The Clone Wars (film); The Clone Wars, "Hostage Crisis"; "The Wrong Jedi"; Catalyst: A Rogue One Novel)

Kamino Security Force#

They wore armor similar to the Coruscant Guard's shock troopers but with gray markings instead of red. They kept order on Kamino, where Jedi Master Shaak Ti oversaw clone trooper training, and they stayed on duty there after the Republic became the Empire. (The Clone Wars, "The Unknown"; The Bad Batch, "Aftermath")

Fifth Fleet Security#

Continuity: Legends.

The last law enforcement formation on the list, and the thinnest documented. They are only known to have worn navy blue armor markings and to have been responsible for maintaining security aboard Republic cruisers. (Star Wars: Battlefront II (2005))

Clone legions#

Continuity: canon and Legends.

A legion held around 9,200 soldiers and was typically led by a Jedi General with a senior Clone Commander beneath him. (Star Wars: Complete Locations)

501st Legion#

The most famous unit in the entire army. Both the 332nd Company and Torrent Company belonged to it. The 501st fought under Jedi General Anakin Skywalker alongside his apprentice Ahsoka Tano, Captain Rex and later Commander Appo. Its troopers were known for bravery, daring tactics and devotion to the Republic. They fought at Christophsis, the Second Battle of Geonosis, Umbara, the Siege of Mandalore and, at the end, the assault on the Jedi Temple. After the Empire was founded the 501st continued to serve Skywalker under a new name: Vader's Fist. (Star Wars: The Clone Wars (film); The Clone Wars, "Darkness on Umbara"; "Old Friends Not Forgotten"; Revenge of the Sith; Star Wars Battlefront II (2017))

7th Legion#

Continuity: Legends.

Overseen by senior Clone Commander A'den and part of the 327th Star Corps under Aayla Secura and Commander Bly. Clone Commander Faie was also attached to the 7th and took part in the Siege of Saleucami, its most notable action. The Hawkbat Battalion sat within the 7th. (Republic 74; Star Wars Insider 84)

187th Legion#

An elite unit organized under the 91st Mobile Reconnaissance Corps and commanded by Mace Windu. Its purple and light blue armor markings echoed its Jedi General's purple lightsaber blade. Most of what is known about it comes from toy lines; the troops Windu led on screen at the Battle of Anaxes belonged to a separate unit with the same number, the 187th Battalion. (The Clone Wars, "The Bad Batch")

Doom's unit#

Led by Commander Doom. Its infantry carried their own variant of blast shield and were seen using Z-6 rotary blaster cannons in combat. Its most significant action was the Battle of Ringo Vinda, where the twin Jedi Generals Tiplar and Tiplee took command alongside Doom. (The Clone Wars, "The Unknown")

182nd Legion#

Continuity: Legends.

Identifiable by its red marked troopers. One of its squads was commanded by clone Sergeant Marrt. No Jedi General or Clone Commander has ever been attached to the legion on record. (Star Wars: Battlefront II (2005))

Clone battalions#

Continuity: canon and Legends.

A battalion consisted of four companies of 144 clone troopers each, for a total of 576 men, and was typically led by a Jedi General with a Clone Commander or major. (Star Wars: Complete Locations)

212th Attack Battalion#

The legendary one. It included Ghost Company, the 2nd Airborne Company and Eagle Company. Like the 7th Sky Corps it belonged to, it was led by Obi-Wan Kenobi and Commander Cody. The battalion built its reputation on siege breaking tactics and frontal assaults, and it was deployed repeatedly across the war: Christophsis, Ryloth, the Second Battle of Geonosis, Umbara, Anaxes and Utapau. (Star Wars: The Clone Wars (film); The Clone Wars, "Innocents of Ryloth"; "Landing at Point Rain"; "The Bad Batch"; Revenge of the Sith)

104th Battalion#

Better known as the Wolfpack. Throughout the Clone Wars the 104th was commanded by Clone Commander Wolffe and Jedi General Plo Koon. Its appearance changed over the war, starting with maroon markings on phase one armor before switching to a grey scheme. They fought at Abregado, the Kaliida Nebula, the Second Battle of Felucia, Lola Sayu and Kadavo. (The Clone Wars, "Rising Malevolence"; "Escape from Kadavo")

Rancor Battalion#

Led by ARC Trooper Commander Colt alongside Commanders Blitz, Havoc and Hammer. In the early stages of the war those four Advanced Recon Commandos oversaw training on Kamino. The battalion's infantry can be picked out by the maroon and grayish blue markings on their helmets and arms. Their best known action was the Battle of Kamino, defending Tipoca City against wave after wave of Separatist forces. (The Clone Wars, "ARC Troopers")

13th Battalion#

Also called the Iron Battalion, commanded by Jedi General Jaro Tapal and his Padawan Cal Kestis. Its soldiers wore yellow marked phase two armor, and the battalion's commander was issued the same gear as the standard infantry. The 13th fought in the invasion of Bracca and later carried out Order 66 against its own Jedi, which killed Tapal. The entire battalion then died when their Venator class Star Destroyer was destroyed. (Star Wars Jedi: Fallen Order)

Hawkbat Battalion#

Continuity: Legends.

A unit placed within the 327th Star Corps. Its troopers were supported by LAAT gunships and wore phase one armor. Clone Major Twelve led Hawkbat into the First Battle of Geonosis, where most of the battalion was destroyed following orders to march on a line of Separatist spider droids. (Star Wars: Clone Wars; Star Wars Insider 84)

Lancer Battalion#

Continuity: Legends.

Occasionally deployed against the Separatists' IG lancer combat droids and battle droid columns. These specialized speeder mounted warriors attacked at close quarters, spearing enemies with their lances. During the Battle of Muunilinst the battalion was led against Durge's forces by Jedi General Obi-Wan Kenobi, equipped in phase one clone trooper armor. (Star Wars: Clone Wars)

Grey's Battalion#

Commanded by Jedi General Depa Billaba, her Padawan Caleb Dume, Clone Commander Grey and Captain Styles. On Haruun Kal the battalion faced General Grievous and took such heavy casualties that Billaba was given a second battalion of young, inexperienced clones, with Grey, Styles and two other veterans returning to serve under her. That second battalion fought on Kardoa and Mygeeto and turned on its Jedi on Kaller when Order 66 came through. (Kanan 2; Kanan 9)

41st Scout Battalion#

A subunit inside the 41st Elite Corps that supported the defense of Kashyyyk. Like the corps above it, the battalion answered to Yoda, Luminara Unduli and Commander Gree. Its infantry were scout troopers in specialized camouflage armor, and the unit has not been seen since. (Revenge of the Sith; Star Wars Battlefront II (2017))

Sarlacc Battalions#

Continuity: Legends.

Also within the 41st Elite Corps. Sarlacc Battalions A and B deployed together as a single brigade of 1,152 men on Dinlo under Jedi General Vaas Ga and Commander Gree, and heavy battle droid resistance forced their extraction. (Republic Commando: Triple Zero)

612th Attack Battalion#

Continuity: Legends.

An infantry unit led by Commander Ganch and assigned to Jedi Master Bolla Ropal, working closely with his Padawan Tyzen Xebec. After Ropal's death the 612th passed to Jedi General Keelyvine Reus, Xebec's new master. Little else is recorded about them. (The Clone Wars: Act on Instinct)

442nd Siege Battalion#

A unit that specialized in besieging enemy strongholds. Its soldiers frequently used vehicles such as the AT-RT and wore phase two armor with green markings. They were sent to Cato Neimoidia in the final moments of the war alongside Jedi General Plo Koon and a clone commander. That is where Order 66 came through, and where Koon's Jedi starfighter was shot down by his own wingman, Captain Jag. (Revenge of the Sith)

Combat Engineer Battalion#

Continuity: Legends.

A subdivision of the 38th Armored Division. These clone combat engineers specialized in operating heavy artillery, including turbolaser walkers and Republic artillery guns. Their heavy artillery soldiers wore white armor with dark brown markings. They were stationed on Kashyyyk under Jedi Master Yoda and sent wherever armoured support was needed. (Threats of the Galaxy)

Clone companies#

Continuity: canon and Legends.

Each company consisted of 144 troopers and was usually led by a Clone Commander or a captain. (Star Wars: Complete Locations)

332nd Company#

A subunit of the 501st Legion. Ahsoka Tano, the recently promoted Commander Rex and Captain Vaughn were given command of the company so they could stage an invasion of Mandalore alongside Bo-Katan Kryze and her forces. When Ahsoka returned, the company's infantry repainted their helmets in tribute to their Jedi commander. After Maul was captured, Order 66 came through and the company tried repeatedly to kill Tano, who escaped with Rex's help. Their Venator class Star Destroyer crashed on a moon and the rest of the 332nd died with it. (The Clone Wars, "Old Friends Not Forgotten"; "Victory and Death")

Torrent Company#

Another subunit of the 501st, and an elite one, led by Jedi General Anakin Skywalker, Jedi Commander Ahsoka Tano and clone Captain Rex. Torrent fought the Separatists across a string of engagements including the battles of Christophsis and Teth. (Star Wars: The Clone Wars (film))

Green Company#

A clone trooper infantry unit belonging to the 41st Elite Corps, once again under Commander Gree and Jedi Master Luminara Unduli. Its members wore phase one armor painted with the 41st's green markings. Their most notable action came aboard their Star Destroyer, the Tranquility, where they had been assigned to transport Nute Gunray. Separatist forces attacked the ship, leaving Green Company to repel the boarders at the cost of heavy clone casualties. (The Clone Wars, "Cloak of Darkness")

Ghost Company#

A detail within the 212th Attack Battalion whose high ranking infantry wore clone trooper armor with light orange markings. They were led at the Battle of Ryloth by Obi-Wan Kenobi and Commander Cody, alongside troopers Boil and Waxer, who were instrumental in liberating the planet. (The Clone Wars, "Innocents of Ryloth"; "Liberty on Ryloth")

2nd Airborne Company#

Another subunit of the 212th, made up of specialized clone paratroopers. The company was deployed at the Battle of Utapau, where Order 66 turned the 212th on Kenobi. Its troopers were issued helmets designed for high altitude drops, and orange slashes across their chest plates marked their affiliation with the 2nd. (Revenge of the Sith)

Keeli's Company#

A unit under Captain Keeli and Jedi General Ima-Gun Di. The company's troopers wore the dark brown markings of the Outer Rim garrison. At the Battle of Ryloth they fought alongside freedom fighters commanded by Cham Syndulla while buying time for civilians to escape waves of battle droids. Keeli's Company fought down to the last man, with both Keeli and his Jedi General sacrificing themselves for the people of Ryloth. (The Clone Wars, "Supply Lines")

Horn Company#

Continuity: the name is Legends; in canon this is simply Eeth Koth's unit.

Commanded by clone Captain Lock and Jedi General Eeth Koth. Its troopers wore phase one armor with green and yellow markings. They were assigned to the Venator class Star Destroyer Steadfast when General Grievous attacked. After half the company was killed, Koth ordered the survivors to escape and allowed himself to be captured. (The Clone Wars, "Grievous Intrigue")

Tango Company#

Led by Barriss Offee, Ahsoka Tano and clone Lieutenant Trap. Every trooper in Tango Company was infected with Geonosian brain worms after the Second Battle of Geonosis while aboard a Republic medical frigate. The infected clones lost control of their minds, killed their pilot brothers and turned on their Jedi commanders. The company wore phase one armor with light blue markings, and many of its clones displayed Tango Company's emblem prominently on their plates. (The Clone Wars, "Brain Invaders")

K Company#

Continuity: Legends.

Organized under Hawkbat Battalion out of the 327th Star Corps and commanded by Captain Deviss. Deviss survived the First Battle of Geonosis, where most of Hawkbat Battalion was destroyed, and was promoted to Commander afterward. He went on to command K Company in later fighting. (Star Wars: Clone Wars; Star Wars Insider 84)

What this list leaves out#

The units above cover the corps, legions, battalions and companies of the Grand Army. They are not the whole picture. Divisions, clone commando groups, starfighter squadrons and a range of other specialist formations sit outside those four tiers, and they run deep enough to need their own guide. If you want more on the men themselves rather than the paperwork, the Clone Wars overview and Captain Rex are the places to start. (Star Wars: Complete Locations)
