RC - 1138 RC - 01 / 138 — simplified as RC - 1138 and also known as Delta - 38 or by his nickname of Boss — was a clone of Mandalorian bounty hunter Jango Fett . Born in 32 BBY on the watery world of Kamino , Boss was trained by the Mandalorian " Cuy ' val Dar " training sergeant Walon Vau to become a clone commando in the Grand Army of the Republic . Placed in command of three other commandos , Boss lead the elite special forces unit Delta Squad as their sergeant . When the Clone Wars broke out between the Galactic Republic and the Confederacy of Independent Systems , Boss took his place in the Grand Army ' s Special Operations Brigade under Jedi General Arligan Zey , and served alongside his clone brothers in Delta Squad on a number of battlefields , ranging from the deserts of Geonosis , the halls of the RAS " Prosecutor " , and the streets of Coruscant , to snowy Mygeeto and the plains of Haurgab . Following the transformation of the Republic into the Galactic Empire , Boss and the other members of Delta Squad — minus squadmate RC - 1207 , whom the squad had been forced to abandon on Kashyyyk in the final days of the Clone Wars — served in the new Imperial Army , as members of the Imperial Commando Special Unit , a specialized unit within the 501st Legion tasked with hunting down clone , fugitive Jedi Knights and Jedi sympathizers . Biography . Early life and training . RC - 1138 was born in the year 32 BBY , in the cloning facilities of Tipoca City , on the aquatic planet of Kamino . A clone of the Mandalorian bounty hunter Jango Fett , RC - 1138 was created to serve in the Grand Army of the Republic as a clone commando and , following a course of flash training , was placed under the direct training of the Mandalorian " Cuy ' val Dar " training sergeant , Walon Vau . As his training progressed , Three - Eight proved himself an incredibly capable soldier , consistently scoring the highest of his clone brothers in weapon and tactics training . During a test of his melee skills with his training sergeant , Three - Eight broke Walon Vau ' s arm . With these accomplishments in mind , Vau assigned RC - 1138 to Delta Squad , one of the first commando squads established by the Kaminoans , where he would serve as its sergeant , and thus came to be known as " Boss " to his three squadmates , RC - 1140 , RC - 1207 , and RC - 1262 — known informally as " Fixer , " " Sev , " and " Scorch , " respectively . Geonosis . The Grand Army would finally see action in 22 BBY , when Jedi Grand Master Yoda took the army to the Outer Rim world of Geonosis to rescue Jedi Knight Obi - Wan Kenobi , his Padawan Anakin Skywalker , and Galactic Senator Padmé Amidala . Boss and the other members of Delta Squad were sent to Geonosis in a deployment so hastily ordered and carried out that it left Delta no time to say goodbye to their training sergeant , Vau . The four commandos split up , each boarding a single LAAT / i gunship independently , with the intention of rendezvousing once on the surface of Geonosis . Aboard his gunship , Boss spoke with Clone advisor CC - 01 / 425 , with the latter introducing himself and reminding Delta Squad of its tasking , assassinating Geonosian Archduke Poggle the Lesser ' s chief lieutenant , Sun Fac . As the gunship landed , it was assaulted by a single Geonosian warrior ; Boss was helpless to stop it from quickly killing another clone trooper who had ridden with him in the troop bay . Once on the ground , Boss was called upon to destroy an armored bunker on his way to rendezvous with the other members of his squad , a task he completed utilizing a thermal detonator . Upon reuniting with his other squadmates , Boss and the rest of Delta Squad attacked Sun Fac in his command center , but the Geonosian leader managed to escape . Delta tracked Fac through the Geonosian catacombs , eventually catching up with him in Fac ' s private hangar as the Geonosian attempted to escape in his starfighter . Fac ' s escape was prevented by the timely actions of Delta Squad ' s sniper , Sev , who used the sniping attachment of his DC - 17m blaster rifle to shoot down the starfighter , killing Fac . While hunting for Sun Fac , Delta Squad had engaged a number of spider droid s while their fellow Republic commando unit , Theta Squad , blew through a door in the catacombs . Boss had been in contact with Theta ' s demolition expert , RC - 1136 , and had emphatically encouraged the commando to make haste . Once the door was down , Delta was given leave to enter and fire on the Geonosians inside , while Theta moved off to destroy a droid factory . Once Sun Fac was dead , Delta Squad ' s advisor informed them that Theta Squad had failed in their objective ; RC - 1133 , RC - 1134 , and RC - 1135 had been killed , leaving RC - 1136 the only survivor . Boss and his Delta squadmates infiltrated the factory — their route taking them through an area filled with Geonosian eggs — and successfully destroy it by targeting specific weak points in the factory ' s design . Following the destruction of the droid factory , Delta Squad was ordered to infiltrate a " Lucrehulk " - class Core Ship . Deployed in a nearby canyon from an LAAT / i gunship piloted by clone pilot Delta 42 , Delta Squad made their way to the Core Ship , using a downed gunship ' s composite - beam turrets to fend off enemy Geonosians along the way . As they continued toward the Core Ship , Boss and his squad were called upon to take out an anti - aircraft cannon . The commandos fought through a number of B1 battle droids and their super battle droid counterparts , before finally destroying the large anti - aircraft emplacement . When the squad finally reached the Core Ship , they were met with resistance from an advanced spider droid and a ray shield blocking the ship ' s entrance . The four commandos were able to destroy the spider droid with considerable effort — with Boss making note of his desire never to have to engage one again — and they then called in air support from Delta 42 ' s gunship to blow through the ray - shielded entrance . Once inside , Delta Squad split up , each of its members tasked with sabotaging and destroying various crucial systems : Boss struck at the super battle droid storage racks . When Scorch and Fixer came under heavy fire from a small number of droidekas , Boss and Sev were able to rescue them without incident . Their primary objective , however , was the capture of vital launch codes housed on the ship ' s bridge . On the bridge , Delta came under heavy fire from numerous battle droids and stationary autoturrets , but still managed to acquire the codes before retreating down a branching corridor . By then , the squad ' s efforts to sabotage the Core Ship had come to full fruition , with several primary systems overloading . With no time to escape back the way they had come , Delta Squad was extracted via LAAT / i gunship through a hole forcefully blown in the hull of the ship . The Battle of Geonosis would be the first action Boss and his brothers from Delta Squad saw , but with the Clone Wars breaking out throughout the galaxy between the Galactic Republic and the Confederacy of Independent Systems , it would not be the last . Delta would prove to be one of the lucky minority of Republic commando squads to depart Geonosis intact and with no casualties ; 4 , 982 other commandos perished on Geonosis ' red sands . Mission to the " Prosecutor " . One day before the first anniversary of the Battle of Geonosis , three hundred and sixty - seven days into the Clone Wars , Boss and the rest of Delta Squad were called upon to investigate the " Acclamator " - class assault ship , " Prosecutor " . Having recently reappeared in the Chaykin Cluster following a two - week - long disappearance while tasked with defending trade routes in the Corellian sector , the " Prosecutor " was found drifting , without power or communication capability . Delta Squad had spent a substantial amount of time aboard the capital ship during the early portion of the war , and Boss had even come to think of it as their " first home " . Arriving on scene in the Corbantis system aboard a CR25 troop carrier , Delta Squad was tasked with retrieving flight records from the " Prosecutor " four data cores and securing the derelict assault ship . The four members of Delta Squad disembarked from the CR25 via a jump through the vacuum of space , splitting up and entering the " Prosecutor " at four different locations . Interference in their comms would quickly cut Boss and the others off from the guidance of CC - 01 / 425 , who was again serving as mission advisor to the squad . While searching through the ship , Delta Squad came across few survivors , and several members were set upon by scavenger droid s ; Scorch was ambushed and incapacitated by the droids . Shortly after , the squad found that the " Prosecutor " has been attacked by Trandoshan slavers and mercenaries when Sev was attacked and captured at the starboard data core where Boss had been waiting to meet him , and Boss was forced to flee into the ship ' s maintenance shafts . Despite this , Boss was able to complete his original objective , battling through heavily armed and armored Trandoshan mercenaries and the ship ' s very own autoturret defenses that had been sliced by the Trandoshans , before rendezvousing with Fixer and proceeding to rescue Sev . Once Sev was free of the violent interrogation from his Trandoshan captors , the incomplete squad moved to retrieve Scorch from where he was being held in the " Prosecutor " detention area . After a brief skirmish in the detention area , Delta Squad was able to locate and revive an incapacitated Scorch , and together make their way to the bridge where they destroyed a Confederacy jamming device and re - established communication with their advisor . A brief scan revealed that a Trandoshan dropship had touched down in one of the " Prosecutor " hangar bays . Proceeding to the hangar — after being sidetracked through the detention center by a booby - trapped turbolift — Boss and the other members of Delta Squad found that a " Lucrehulk " - class battleship had entered the system and was rapidly approaching the " Prosecutor " . While their advisor called for assistance , Delta Squad was charged with repelling the droid boarding parties and sealing the assault ship ' s hangars . By the time Boss and the others reached the final hangar , it was overrun with droids and the commandos had to resort to commandeering the roof - mounted mass - driver cannon of an AT - TE walker to deal with the droid threat . Following these events , the Separatist battleship opened fire on the " Prosecutor " , deciding to cut its losses and destroy the Republic warship before reinforcements could arrive . In an attempt to hold off the battleship , Delta Squad struggled to get the " Prosecutor " turbolaser battery array back online amidst a continuing assault from droid forces already onboard . Reinforcements would come in the form of Republic Navy Captain Talbot and the RAS " Arrestor " , the only Republic force to respond to CC - 01 / 425 ' s calls for assistance . Between the combined strength of the " Arrestor " and " Prosecutor " — even as the latter ' s hull integrity was compromised — the Confederacy droid control ship was destroyed , shutting down the battle droids aboard the " Prosecutor " , and saving the ship and the lives of Delta Squad . Boss and his Delta Squad brothers were commended by High Jedi General Mace Windu for their actions aboard the " Prosecutor " , and the data that they retrieved would help enable the Wookiees to better combat Trandoshan slaving operations in the Kashyyyk system . Rescue of Omega Squad . Delta Squad departed the " Prosecutor " aboard a stolen , unarmed Neimoidian vessel , and shortly thereafter received a Red Zero signal — the Grand Army code requesting immediate extraction — from their fellow commando unit , Omega Squad , near the Kelarea system . Omega was trapped aboard a damaged freighter along the intersection of the Corellian and Perlemian Trade Routes , with no power , limited oxygen , and a trio of prisoners suspected of terrorist activity , which they had captured during an earlier Traffic Interdiction Operation . With no other Republic forces close enough to provide the much - needed assistance , Delta Squad took it upon themselves to respond . Boss consulted with Jedi General Etain Tur - Mukan en route , discussing the best plan for extracting Omega with a Separatist ship moving on their location at the same time . Delta Squad arrived on scene and quickly set about rescuing their fellow commandos , while General Tur - Mukan arrived with the " Acclamator " - class ship " Fearless " just in time to destroy the enemy ship before it could attack . Once Omega was safely on board , Sev nearly provoked a physical confrontation with Omega Squad member Atin ; Boss made no move to intercede , leaving it to Omega Squad ' s sergeant , Niner , to break up the budding conflict before it could come to blows . Both Delta and Omega Squads then docked aboard " Fearless " and returned to Coruscant . War on terror . Upon setting down on Coruscant , Delta Squad disembarked from " Fearless " along with Omega , and were met by former " Cuy ' val Dar " training sergeant , and now military advisor to Special Operations Brigade , Kal Skirata . Unfortunately for Boss and the others , Skirata overheard Scorch ' s disparaging comments made at the expense of his advanced age , and ordered the squad to perform fifty pushups . Once they were finished — although Skirata teased that they had only completed forty of the fifty he ' d assigned — the commandos of Delta and Omega offloaded the three prisoners into a waiting speeder piloted by Skirata ' s Wookiee associate , Enacca , bound for interrogation at the hands of Delta ' s former training sergeant , Walon Vau . A transport arrived soon after to take Delta and Omega back to Arca Barracks . At 1500 hours , Delta met with Skirata and Omega Squad in one of Special Operations Brigade Headquarters ' briefing rooms , where Skirata attempted to ease the tension between the two squads , insisting that Atin and Sev leave behind their grudge and shake hands . When the Null - class Advanced Recon Commando Captain known as Ordo arrived at the meeting , Skirata informed both Delta and Omega that they would be involved in a black ops strike against a terrorist cell operating on Coruscant . Delta Squad , along with Omega and the other members of the covertly assembled strike team — now including Jedi Generals Tur - Mukan and Bardan Jusik , along with Vau and Vau ' s pet strill , Lord Mirdalan — moved into the top floor of Qibbu ' s Hut , a shady cantina and hotel in Coruscant ' s Uscru Entertainment District , owned by an associate of Skirata by the name of Qibbu the Hutt . Over the following days , Boss and the other members of Delta Squad would take part in a rotating surveillance watch with the members of Omega , and despite conflicts between members of the two squads where their distinct personalities clashed , the two squads worked together effectively and even came to develop a respect for one another . Using Qibbu ' s criminal contacts , the strike team was able to lure their terrorist targets — who they determined hailed from Jabiim — under the pretense of having a supply of five - hundred - grade thermal plastoid explosive that they were willing to sell . After a meeting between Skirata and the terrorist leader Perrive establishing a time when they would supposedly make the explosives sale , Delta Squad spent an evening enjoying themselves at Qibbu ' s bar with the other members of the strike team , at least until the revelry was cut short by a call from Perrive stating they would need to move up their time and change the pre - established location . Fortunately , the new location for the trade was a CoruFresh produce distribution depot in Quadrant F - 76 of Galactic City , a location Delta Squad had personally reconnoitered earlier . Together with the other strike team members , Boss and Delta Squad donned their armor again for the first time since the operation had truly begun , and moved out to end the terrorist threat . At the CoruFresh depot , Boss and Scorch took positions covering the northern landing strip . Once Skirata and Jusik passed the explosives off to the terrorists and cleared the area as planned , the assembled troops struck , shutting off the lights and attacking from every direction , including the roof . Delta Squad neutralized the terrorists who fled into the repulsortruck they had loaded the explosives in , ensuring that there would be no desperate suicidal detonation . A grenade strike nearly wounded Scorch , but Delta ' s demolitions man escaped only shaken . Once the terrorists had all been killed — the assault taking no more than nine standard minutes in total — Boss and the others returned to Qibbu ' s for a final night , and then attended an evening as guests of the CSF Social Club . But just six days later , Delta Squad would be back on assignment , shipped off to Skuumaa and tasked with battlefield preparation consisting of sabotaging strategic targets ahead of the main Republic assault . Mission to Devaron . Boss and the clone commandos of Delta Squad were later dispatched to the planet Devaron in the aftermath of an attack by the Dark Jedi Savage Opress . The squad attempted to locate any survivors of the massacre outside of the Temple of Eedit , but found only corpses . They recovered the bodies of Jedi Master Halsey and his Padawan Knox , and returned them to the Jedi Temple on Coruscant where they reported their findings to members of the Jedi High Council . Mygeeto . Four hundred and seventy days after Geonosis , Delta Squad had been sent to the Outer Rim world of Mygeeto . The squad had been tasked with calling in air strikes and sabotaging Mygeetan ground defenses near the city of Jygat in preparation for Clone Commander Bacara and the Galactic Marines ' main assault . Delta completed their assignments as ordered , but instead of exfiltrating as they were supposed to , the commandos instead decided to assist their former training sergeant Vau in his personal mission , one that consisted of robbing Mygeeto ' s own Dressian Kiolsh Merchant Bank . While Fixer held position near the squad ' s snowspeeder on the planet ' s surface , Boss and the other two members of Delta Squad followed Vau into the underground halls of the bank , where Scorch proceeded to electronically disable the locks on the main vault ' s door . Once inside , however , Vau refused to allow the squad to assist him any further in the heist , determined not to compromise his trainees ' integrity by directly involving them in the actual act of stealing . It was during Vau ' s raid on the vault ' s numerous safety deposit boxes that Boss learned of his former training sergeant ' s past as a disinherited aristocrat from Irmenu , and that the purpose of the theft was to regain the inheritance his mother and father had denied him . When Vau ordered Delta to leave him and continue on with their assigned mission , Boss refused , reminding Vau that he was no longer a sergeant , just a civilian , and instead assisted Vau and his strill carry the stolen loot out of the bank . Unfortunately for both Delta Squad and Vau , their exit would become complicated when one of the bank ' s alarms was triggered . Although Fixer brought the snowspeeder closer to the extraction point , Delta and Vau would have to fight their way through an armed patrol of Muuns and battle droids to escape . During the skirmish , Vau fell through a hole in the ice and into one of the countless crystal - worm tunnels that ran beneath the frozen surface of Mygeeto ; although Delta Squad was determined to retrieve him , Vau forcefully commanded them to leave him and get themselves to safety . Despite severe reservations , Delta Squad did as ordered and exfiltrated from Mygeeto , although each would have some difficulty coming to terms with their perceived abandonment of their former sergeant . Boss , however , contacted Kal Skirata and Null Captain Ordo once they were off planet to inform them of Vau ' s situation at the behest of General Jusik ; Skirata and Ordo immediately traveled to Mygeeto and managed to extract a hypothermic but still alive Vau from beneath the Mygeetan ice . The hunt for Ko Sai . Upon their return to Coruscant from Mygeeto , Delta Squad was debriefed by Jedi General Arligan Zey , the Director of Special Forces , in his office within Special Operations Brigade Headquarters . As Delta ' s squad sergeant , the difficult task of explaining the complications surrounding the squad ' s extraction from Mygeeto fell to Boss , who avoided implicating Vau in any criminal activities with a series of carefully answered half - truths to General Zey ' s questions . When satisfied with Boss ' accounting , Zey passed along the compliments of General Ki - Adi - Mundi to the squad before detailing their next assignment : Supreme Chancellor Palpatine had ordered the capture of the rogue Kaminoan scientist , Kamino ' s own former Chief Scientist Ko Sai . Considering her capture as near a priority as locating the Confederacy ' s Supreme Commander , General Grievous — not only to deny her expertise to the Separatists , but primarily to have an experienced cloner unassociated with Tipoca under Republic control — Palpatine insisted that Zey put his most qualified squad on the assignment , from which Zey selected Delta Squad for the job . Ko Sai had gone missing during the Battle of Kamino , and was suspected to have defected to the Confederacy by Kamino ' s Prime Minister , Lama Su . Despite the length of time between her disappearance and Delta Squad ' s tasking of her retrieval , Kaminoan intelligence was able to track Ko Sai ' s movements to the planet Vaynai . Zey insisted that Delta Squad not inform Kal Skirata of their assignment , knowing of the Mandalorian ' s extreme hate for Kaminoans . Unknown to Delta , Skirata was also hunting for Ko Sai , but for his own reasons : he wished to use the Kaminoan scientist to find a way to halt the accelerating aging that plagued the Grand Army ' s millions of clones . Delta Squad followed the Kaminoans ' intelligence reports to Vaynai , and then on to Aquaris , and from there to Napdu , the fourth moon of the planet Da Soocha , in Hutt Space . During this time , Boss was also battling a cold , from which he suffered a sore throat and repetitive cough ; when Sev mentioned his annoyance at Boss ' continual coughing and throat clearing over the shared comlink , Boss promised to with bacta at his first opportunity . Files acquired from the Nar Hej Shipping Company on Napdu helped Delta to further trace a pattern of movement for Ko Sai , tracking her across the Outer Rim ' s numerous aquatic worlds toward the Tingel Arm . The squad came under attack from a " Crusher " - class starfighter while leaving Napdu in one of the Grand Army ' s TIV vessels , which Boss was piloting . They touched down on Da Soocha ' s third moon , with the " Crusher " continuing pursuit ; on the ground , Boss used the TIV ' s laser cannon to blast away one of the " Crusher " wings , and both Scorch and Sev attacked the wrecked starfighter , killing the female pilot and her male copilot to Boss ' annoyance — dead , they couldn ' t be interrogated . However , Fixer was able to access the ship ' s computer and determine that the pair were bounty hunters hired by the Kaminoans to track Ko Sai . Using the data acquired from the Nar Hej Shipping Company , Delta Squad tracked down the Twi ' lek pilot , Leb Chura , on Bogg 4 . Boss and the others interrogated Chura as to Ko Sai ' s whereabouts with the assistance of General Bardan Jusik . Chura had been moving cloning materials from Arkania to Dorumaa , but the Twi ' lek had already relayed this information to Skirata and Vau . In order to keep Skirata and his quest a secret , Jusik influenced Chura to recall Mandalorians wearing green armor instead of Skirata and Vau ' s more recognizable golden and black sets when asked , and upon learning that Chura had delivered the consignment to a location near Dorumaa ' s Tropix Island Resort , Jusik erased the pilot ' s memory of both Delta and Skirata ' s band , along with deleting the records on his datapad . In spite of this , Boss and his brothers acquired SCUBA trooper armor and traveled to the resort world of Dorumaa . There , they acted as part of a utilities maintenance crew in order to gather surveillance which led them to a collapsed area underneath Tropix ' s neighboring ActionWorld island . Upon investigating , the squad found the skeletal remains of a human who had been chain ed beneath the water , and the collapsed entrance to the facility that had previously belonged to Ko Sai . Skirata and his crew had arrived first , capturing the Kaminoan scientist , destroying the laboratory , and taking her back to Skirata ' s home on Mandalore . The squad was tasked with the slow excavation of the area ; at one point they inserted a small strip - cam through an available opening , finding the armored remains of the Mandalorian bodyguards Ko Sai had hired . Though Delta found no further evidence over the next few weeks of excavation , they remained unyieldingly loyal in covering for General Jusik ' s absence while the Jedi Knight secretly sneaked away to aid Skirata . Five hundred and forty - eight days into the Clone Wars , Boss and the other Deltas were called back to Special Operations Brigade on Coruscant , where they were met by Kal Skirata . There , Skirata gave Sev a package containing Ko Sai ' s severed head ; the rogue Kaminoan had taken her own life while being held on Mandalore , and was cut into pieces post - mortem . Sev then delivered Ko Sai ' s head to General Zey for confirmation of death , neglecting the details of how it had come into Delta ' s possession while still telling Zey as much of the truth as he knew using tightly wound word games . Mission to Haurgab . Approximately nine hundred and seventy days into the Clone Wars , Boss and the other members of Delta Squad found themselves on the Separatist - aligned Mid Rim planet of Haurgab . Originally , while Jedi General Mlaske and the Grand Army ' s 85th Infantry Brigade were already operating on Haurgab , the only Republic commando presence on the dusty backwater world had been Omega Squad , sent to assassinate a key leader of the pro - Separatist Maujasi . However , as time passed , the Republic began to assign more and more Grand Army forces to Haurgab , and Delta Squad , much to their displeasure , soon joined them . During a visit from General Etain Tur - Mukan — who had replaced Bardan Jusik as commander of Delta Squad ' s Commando Group , Zero Five Commando , following his resignation as a Jedi General and his departure from the Jedi Order — the four members of Delta Squad joined a number of other clone troops in the mess hall of the Republic ' s base on the outskirts of the Haurgab city of Hadde . While Delta was sitting at a table with their food — trading jokes and theories on assorted topics — the base was struck by a missile from within the city limits ; though numerous troopers were killed and wounded in the attack both from the blast and the resultant shrapnel , Delta Squad had been spared the worst injuries thanks to their hardy " Katarn " armor . The shock of being attacked in a place that had always been perceived as safe and the sight of so many dead and injured clones drove the normally lighthearted Scorch into a rage , and together with Omega Squad , General Tur - Mukan , and elements of the 85th and 14th Infantry Brigade s , Boss led Delta Squad in a retaliatory strike against the rebel forces . When they arrived at the house where the missile had originated , Scorch insisted on being part of the assault team for the raid ; recognizing the catharsis that confronting the responsible party would bring , Boss obliged his brother , and he and the rest of Delta stood by as security to deal with any potential attack from another source . During the shootout , four rebels were captured , while another three were killed . Death would prove not to be enough for Scorch , however : the infuriated commando dragged the rebels ' lifeless bodies out into the street where he riddled them with blasterfire before finally spitting on each of the charred corpses . Boss again kept Scorch from being interfered with , holding Sev back from attempting to comfort the angry commando until he had finished . Felucia . During the war , Boss commissioned a Jedi Knight to defeat Scratch , C - 21 Highsinger , a B3 ultra battle droid , and Yorn Nuro . Kashyyyk . Around one thousand and seventy days after the Battle of Geonosis , Delta Squad was sent to the Wookiee homeworld of Kashyyyk in the Mytaranor sector . Following a Separatist - backed invasion by Trandoshan slavers , the Wookiee chieftain Tarfful had been taken prisoner . Tarfful had spent years combating Trandoshan slaving parties , and without him the Wookiees turned to the Republic for assistance . In response , Delta Squad was deployed to Kashyyyk in order to extract Tarfful from captivity , in a mission where Advisor CC - 01 / 425 oversaw Delta yet again . Boss and the rest of Delta Squad covertly inserted into Kashyyyk via LAAT / i gunship , rappelling to the planet ' s surface from the troop bay . Once on the ground , the squad moved through the planet ' s dense jungle until coming upon the camp of the Trandoshan slavers . Battling their way inside , the squad was ambushed in a narrow corridor by Trandoshan mercenaries on the overhead catwalks , forcing them to escape through a maintenance shaft toward a landing zone . After securing the landing zone , the commandos caught a glimpse of a Belbullab - 22 starfighter matching the profile of General Grievous ' ship , " Soulless One " . Continuing through the slavers ' base , Delta freed a number of imprisoned Wookiees on their way to locate Tarfful before Delta ' s advisor tasked the squad with another objective : confirming Grievous ' presence on Kashyyyk . Climbing a tower close to the general ' s landing pad , Boss and Delta managed a visual confirmation on the general , before nearly being attacked by one of Grievous ' IG - 100 MagnaGuards . Rushing down the tower , Delta Squad found Tarfful being escorted to Grievous ' fighter by two MagnaGuards ; although Tarfful successfully destroyed the droids on his own , Grievous fled the planet in his starfighter , leaving behind another pair of MagnaGuards . Though Grievous had initially wanted the Wookiee chieftain alive for questioning , now that the opportunity had been taken from him , the commander of the Separatist Droid Army instead ordered Tarfful dead so as to deny the Republic the valuable intelligence Tarfful possessed . Boss and the other commandos of Delta Squad engaged the deadly droids in an effort to protect Tarfful , although the Wookiee warrior refused to back down from his attackers . Together , the commandos and their Wookiee ally defeated the droids , and Tarfful was taken to Coruscant in order to enlist further Republic assistance . Delta Squad destroyed another Trandoshan encampment not long after , before moving on the bridge near the Wookiee village of Kachirho . By this time , Delta had been joined by Jedi General Etain Tur - Mukan on order of General Arligan Zey , who believed that she would prove beneficial to the mission . She tasked the squad with destroying the bridge : without it , the Separatist supply lines would be cut off , while the Wookiees could construct smaller bridges to circumvent the loss , an option the Confederacy ' s battle droids didn ' t have . Moving through an occupied market concourse , Boss and Delta fought their way through numerous Trandoshan grenadiers and heavily armed mercenaries along with another advanced spider droid and countless battle droids to reach the Kachirho bridge , where Delta Squad placed a detonation pack at the center of the bridge where it was weakest . However , when Boss attempted to detonate the charge , the explosives misfired . Though he was understandably angry at the setback , Scorch borrowed a rocket launcher from a female Wookiee and used it to destroy the bridge . Thirteen days later , Delta continued operations on Kashyyyk , even as Coruscant came under attack by General Grievous . While preparing to ambush a Separatist droid patrol , Scorch and Sev listened in on the comlink traffic from Coruscant , learning that only commandos in the Inner Rim had received the Code Five signal to return to Coruscant immediately . When General Tur - Mukan expressed her concern for her loved ones residing on the Republic ' s besieged capital , Boss and the others took it upon themselves to comfort her , and when she revealed that she had a son , they promised to keep her secret , with Boss going so far as to say , " We didn ' t even hear you tell us that . We know nothing . " Though the battle droid patrol would fall victim to Wookiee - made pitfalls , Delta and Tur - Mukan ambushed a small group of Trandoshans scouting through the Wroshyr trees , disposing of their dead bodies via a plant . Five days later , with the crisis on Coruscant over , Delta Squad was joined on Kashyyyk by the clone forces of Jedi General Quinlan Vos , arriving from Boz Pity . In addition , General Yoda was inbound with the 41st Elite Legion and Wookiee Chieftain Tarfful , set to land within thirty standard minutes . However , a " Recusant " - class light destroyer had taken up position to engage Yoda ' s cruiser and halt the debarking of additional ground troops . With a bit of good - natured coaxing from General Tur - Mukan , Boss and Delta Squad infiltrated a Separatist turbolaser battery complex with the intent to commandeer the contained firepower to take out the " Recusant " - class destroyer . With Clone Commander Gree considering alternative landing sites — each too far removed from the main offensive to be effective — Delta Squad captured one Wookiee dual missile turret for each commando , and opened fire on the Commerce Guild destroyer , joined in the attack by a wing of General Vos ' LAAT / i gunships . After sustaining heavy damage , the " Recusant " destroyer began to fall , but while the majority of Delta Squad planned for a hasty exit , Sev radioed in with a report of coming under attack from multiple hostiles . When Boss ordered the squad to go back for Sev , Vos ' Forward Air Controller instead ordered Delta to leave , stating that the order had come directly from General Yoda . Though Scorch argued to the point of tears , Boss forced him to comply and moved the remaining three members of Delta Squad onto the gunship that had arrived to extract them , but not without first making a tearful , guilty apology to Sev within the private confines of his helmet . Aboard the gunship , Advisor CC - 01 / 425 confronted Boss via hologram and ordered him to get his squad under control . The advisor then patched through a transmission from General Yoda , who stated that Delta Squad ' s efforts had enabled the Republic to establish forward command in Kachirho , and that the Republic would continue to rely on their skills in the coming battle . Delta Squad was then retasked with a new set of objectives for Kashyyyk . Imperial service . Not long after the conclusion of Republic action on Kashyyyk and the issuing of Order 66 , which branded the Jedi traitors to the Republic who were to be shot on sight , the Clone Wars ended when the Republic was transformed into the Galactic Empire , under the leadership of the now Emperor Palpatine . Nearly eleven hundred days after the Battle of Geonosis , Boss , Fixer , and Scorch found themselves stationed at the Imperial Army Training Center on Centax - 2 , one of the moons of Coruscant and the location of the secret Spaarti cloning cylinder - based second clone army that Palpatine had created . There , they would continue to lament the loss of Sev , especially in the face of the revelation that although Omega Squad members Atin and Corr had deserted the Grand Army , Darman and Niner had joined Delta in the new Imperial Army because Darman had refused to leave a badly wounded Niner behind on his own . Three weeks after the formation of the Galactic Empire , Delta Squad — with a replacement for Sev among their ranks — gathered at the 501st Legion headquarters on Coruscant with a number of other former Republic commandos and Advanced Recon Commandos for an audience with Darth Vader . There , Vader reformed the Republic ' s former special forces soldiers as the Imperial Commando Special Unit , an elite unit within the Imperial 501st Legion that would be tasked with hunting down Jedi who managed to escape Order 66 , along with clone deserters , Jedi sympathizers , and other Imperial dissidents . Their serial numbers ' " RC " prefix was replaced with an " IC " to denote their new position as Imperial Commandos , and the squad was also given a different and more numerical - based name , similar to the former Omega Squad being renamed " Squad 40 . " Although initially under the command of the Emperor ' s Hand , Sa Cuis , the Imperial Commando Special Unit was taken over by Imperial Commander Roly Melusar — a native of the planet Dromund Kaas and a man with a firm hatred of all Force users — following Cuis ' death . Melusar ' s zealous hate for the Jedi and all other beings who could wield the Force led Scorch to tag Melusar with the nickname " Holy Roly , " a name Boss remarked would likely stick and , in fact , " did " among the ranks of the Imperial Commando Special Unit . Personality and traits . RC - 1138 — nicknamed " Boss " for his role as the leader of Delta Squad — was an incredibly gifted soldier . Scoring higher than most of his clone commando compatriots during his training on Kamino at a young age , Boss impressed his Mandalorian training sergeant , Walon Vau , with his prowess . Though a natural leader , Boss was relatively taciturn , and often when he did speak , it was to issue an order to his squad . Boss earned the respect and loyalty of his Delta Squad comrades , and did his best to repay their faith in him with strong , effective leadership . He cared a great deal for his squadmates and , like most other clone commandos , viewed his team as brothers . Despite being raised and trained by " Cuy ' val Dar " sergeant Walon Vau , Boss came to speak with Jango Fett ' s Concord Dawn accent and speech patterns — though this trait was common to the flash - learned standard clone troops , as well .
