Omega Squad Omega Squad was an elite clone commando unit hi , and was part of the Grand Army of the Republic during the Clone Wars . The members of this unit were brought together after each of their respective squads were killed during action at Geonosis . Unlike most other commando squads , the Omegas wore specialized Night Ops Armor . It was part of Arca Company of Zero Five Commando . After the formation of the Galactic Empire , the Omega Squad was disbanded , reassigning the remaining members to Squad 40 . Missions . Mission to Qiilura . Omega Squad ' s first mission together was on the planet Qiilura approximately three standard months after The Battle of Geonosis . Jedi Master Kast Fulier and his apprentice Etain Tur - Mukan were on the planet , gathering information , but Master Fulier was captured and promptly killed , and Etain hid . Omega Squad was sent to Qiilura to sabotage research on a clone - killing nano - virus . Ghez Hokan later personally killed Master Fulier with his own lightsaber , which he would later use to kill Cailshh and Guta - Nay . During the planet - fall , Darman was separated from the rest of the squad , and killed some of Hokan ' s thugs who were attacking a village . With help from the Gurlanin Jinart Etain eventually met up with Darman , but accidentally confused him with Ghez Hokan by the notorious Mandalorian T - on his helmet . Luckily for Darman , he was exceptionally well trained in close hand - to - hand combat and was able to disarm Etain and explain . The rest of Omega Squad had to evade natives , and soon enough met up with Jinart . Jinart proved to be a huge help with the mission , by gathering information and acting as a go - between for Darman and the rest of Omega Squad . Later , so all of Omega Squad could talk via comlink , Niner took out the planet ' s communications facility in Teklet , preparing the squad for their final assault . Using tunnels made by gdans , the squad finally assaulted the research facility , and captured the nano - virus along with Dr . Ovolot Qail Uthan . En route to the LAAT / i at the extraction point with Dr . Uthan , Etain , Darman , and Atin had some trouble with Captain Hurati , one of Ghez Hokan ' s men . Hurati seriously wounded Atin with a Verpine shatter gun , smashing through Atin ' s armor plate about 20 centimeters below the armpit . Darman killed Hurati and patched up Atin enough to get to the extraction point , but Dr . Uthan was hit with shrapnel from Atin ' s armor just below the ribs . They made the rest of the way without incident . Unfortunately , Niner and Fi also had trouble , but this time with the former Mandalorian protecting Uthan , Ghez Hokan . In a bold move , Niner lay on the ground , screaming for his training sergeant , Kal Skirata . Hokan attempted to kill the seemingly maimed commando , but Etain arrived just in time to decapitate Hokan with her lightsaber . Fi kept Hokan ' s Mandalorian helmet and armor as a prize . Etain later asked Darman to stay and help her on Quiilura , but he refused saying that he couldn ' t leave his new brothers behind . Galactic City spaceport hostage siege . A month after the Qiilura operation , Omega Squad were stationed at Arca Company Barracks on Coruscant , where they were called upon to defuse a terrorist siege at a local spaceport . With help from Kal Skirata and the Null ARC trooper Captain Ordo , they were able to end the situation . Fi jumped on a bomb to save the rest of the squad and Coruscant Security Forces men , earning him CSF ' s respect . Mission to Fest . Ten and a half months into the war , Omega were dispatched to Fest , to destroy a Separatist research center that was researching phrik alloy . Fest was a frozen wasteland , covered in white snow . Ironically , they were issued new matte black Night Ops Armor just in time for this job , which of course became the source of many jokes from their pilot . However , with the kind of protection the new armor gave , they didn ' t need to hide . TIOPS . Shortly after the Fest operation , Omega Squad were involved in traffic interdiction operations off the Corellian - Perlemian hyperspace intersection . Although they were successful in capturing several suspected Separatist terrorists , they became stranded aboard a damaged vessel and had to be rescued by Delta Squad . They were then picked up by the assault ship " Fearless " , and met up with Etain again . It was during this mission that the TIV pilot , Sicko , that had transported Omega to their objective , was killed by a passing civilian vessel , " Nova Crystal " , who saw what the pilot described as " a pirate ship descending on its prey " . Mission to Coruscant . Following the events of TIOPS , a terrorist attack on a freighter brought the attention of the Coruscant Security Force , as well as Kal Skirata to the situation . While revisiting the incident on a holo - recorder , Captain Ordo , speculated that the terrorists held operatives within Coruscant . Not wanting the risk the lives of thousands of civilians , Kal requested that Delta and Omega Squads return to Arca company barracks for leave to secretly investigate the recent terrorist act . Jedi Master Arligan Zey turned a blind eye to Skirata and granted his request . With the aid of Captain Ordo , Jedi Knights Bardan Jusik and Etain Tur - Mukan , and a former clone instructor Walon Vau , Kal , along with Delta and Omega , began uncovering what was believed to be a Separatist plot . They began by paying a visit to Qibbu , Coruscant ' s resident Hutt to cash in on a favor owed to Skirata . Kal persuaded Qibbu to lend his quarters to serve as a base of operations for the mission , in order to remain inconspicuous . Ordo was then sent out to grab a large number of military grade explosives to attract Separatist attention . Sure enough , a very " interested customer " by the name of Perrive contacted Skirata to discuss further business involving the explosives . Before Kal and his new - found associates meet to discuss terms with one another , Omega and Delta squads along with the two accompanying Jedi positioned themselves along the agreed location and stakeout the transaction . Fi and Scorch marked Perrive and his six consorts with microscopic transmitters designed to look like common dust , courtesy of Jusik . When the suspects dispersed from the scene , the team attempted to track their movements and common locations . In between time during the mission , Darman and Etain Tur - Mukan ' s relationship blossomed into something deeper , which makes Etain question her path to follow the Jedi Order . Within her reasoning , she attempted to give Darman something no other clone in the GAR would have ; " a future " . During reconnaissance , Fi and Sev came across Vinna Jiss , a GAR logistics employee , and sent her to Walon Vau for interrogation . After squeezing information out of Jiss , Vau hurled her off a balcony to her death in the sublevels of Coruscant . Ordo , armed with new information about " Dead - Letter " drops , headed to GAR headquarters disguised as the receptionist clone trooper Corr . Monitoring each movement , Ordo began to suspect Besany Wennen , an attractive female employee with an alluring smile . Much to his surprise , however , Wennen met with Vinna Jiss , whom Ordo had presumed dead . In an attempt to uncover the truth , Ordo returned to GAR HQ in the evening with Etain , to find Vinna Jiss , with Wennen falling behind her . Ordo and Etain trailed and subdued them both , only to later find out that Wennen was an agent of the Republic Treasury Audit Division , and the specter of Vinna Jiss was actually Jinart . As the investigation unfolded and more pieces were added to the puzzle , Kal and his boys began setting up a sting operation , with unexpected help from another Null ARC , Mereel . The explosives were traded off to the suspects for a sum of four - million credits , and the criminals in question were then neutralized . Mission to Olanet . Four hundred and sixty days after Geonosis , Null ARC Trooper Prudii trained Atin on Olanet in his sabotage technique . Together they entered the droid factory on Olanet , which was regarded as a high value target by military intelligence , and sliced the main computer . Prudii then modified the alloy mixture just enough to render droids produced at the factory worthless on the battlefield , but not enough to alert quality controllers that there was anything wrong . Atin then returned to his squad at Coruscant HQ and introduced Omega Squad to the new technique , while Prudii continued his work with his fellow Null ARC brothers in the search for Kaminoan cloner Ko Sai . Mission to Gaftikar . Four hundred and seventy days after the First Battle of Geonosis , Omega Squad was sent to Gaftikar to aid a group of local rebels attempting to overthrow the Separatist government . While there , Darman and Atin infiltrated one of Gaftikar ' s cities disguised as civilians . During their time in the city , they found ARC A - 30 , Sull , who had been missing for nearly two weeks . Atin and Darman managed to return him to their base , and Darman returned to Sull ' s apartment to search for his armor and anything to point towards his involvement with the GAR . While there , he encountered two clone assassins who thought he was Sull . He managed to kill them both , but was shocked that clones would kill their brothers . During the battle for the city , Fi suffered a head injury due to an artillery round hitting the HoloNet station they were sabotaging and became virtually brain - dead . Fi was to be terminated as his injury was deemed incurable by med droids onboard the " Leveler " but due to the actions of Omega Squad and Kal Skirata , he was transported to Republic Central MedCenter for further diagnostics . However , he was recognized solely as government property , not as a man . Besany Wennen went to visit him , and ended up holding him hostage , in order to prevent his termination . CSF Captain Jaller O ' Brim defused the situation and took Besany and Fi back to his home , to begin recovering . Kal Skirata helped to rehabilitate him and bring him back to Mandalore to be nursed back to health by Bardan Jusik and Mandalorian Parja . He was replaced in the squad by Corr . Mission to Haurgab . Maujese rebels were attacking GAR supply convoys on Haurgab and Omega squad was sent to assassinate their leader , Jolluc . They observed the rebels as they raided a few convoys to gather information . When they finally made their move , Corr successfully shot him in the head followed by another shot from Atin when the body twitched . They found themselves however assaulted by more rebels than Intelligence stated . They made a stand on a hill and after a furious firefight , were rescued by a LAAT / i sent by Captain Maze . Return to Coruscant . As Omega returned from Haurgab they were caught up in the Battle of Coruscant . They managed to navigate through the intense space battle and through an opening in the planet ' s shields . Unfortunately a droid starfighter followed them through and caused their ship to crash somewhere in Galactic City . Here they joined the Republic forces in the area , including Yayax Squad , to repel the Separatist invasion . When Order 66 was activated , Omega did not comply as Darman had a relationship with Jedi Knight Etain Tur - Mukan . Instead , disillusioned with the GAR ' s treatment of clone troopers , Omega decided to desert with Kal Skirata and the Null - ARCs . However , the carefully laid plans to evacuate Coruscant were jeopardized when Tur - Mukan was killed at the Shinarcan Bridge Extension , a skirmish in which Niner was also injured . Atin and Corr extracted to Mandalore with Skirata , while Darman remained with the injured Niner . Unable to rejoin their brothers due to the establishment of the Galactic Empire , Darman and Niner were forced to remain commandos . They were combined with survivors of Galaar Squad , becoming Squad 40 of the 501st Legion where they were tasked to capture Jedi and Jedi helpers . Members . Sgt . Kal Skirata ( their field trainer Cuy ' val Dar ) also known as " Kal ' buir " which means " Papa Kal " .
