Clone SCUBA trooper / Legends Clone SCUBA troopers , also known as clone subtroopers , were elite aquatic assault clone troopers grown on the planet Kamino for the Grand Army of the Republic . Trained in underwater tactics and outfitted with specialized clone trooper armor and blasters , clone SCUBA troopers were deployed on numerous aquatic battlefields throughout the Clone Wars , allowing the Galactic Republic to challenge marine foes on equal footing . Jedi Master and General Kit Fisto led units of clone SCUBA troopers on several occasions over the course of the Clone Wars , with the aquatic soldiers proving invaluable during two battles with the Confederacy of Independent Systems on the Outer Rim water - world , Mon Calamari . Description . Born on Kamino and genetically identical to their more common clone brethren , clone SCUBA troopers were an elite group of clone troopers that underwent specialized training in underwater tactics and weaponry for use against aquatic enemies . Outfitted with equipment designed to allow them to wage war effectively while underwater , SCUBA troopers allowed the Galactic Republic to even the odds against aquatic enemies . History . Like all clone troopers , SCUBA troopers were clones of the Mandalorian bounty hunter Jango Fett , born on the planet Kamino , a watery world located in the region of the galaxy known as Wild Space . While the clones of Fett were all genetically identical , with the exception of the Advanced Recon Commandos , a few groups were selected to undergo specialized training for combat in specific environments , training supplemented by equally specialized armor . Equipped with state of the art aquatic gear , clone SCUBA troopers were trained within the oceanic combat simulators of Kamino ' s stilt cities to battle efficiently underwater . As the Clone Wars broke out between the Galactic Republic and Confederacy of Independent Systems in 22 BBY , and the CIS equipped itself with manta droid subfighter s and other aquatic machines — allying itself with marine races such as the Quarren and the Ishi Tib — it became apparent that the Republic would need to make use of its aquatic soldiers and weapons to combat these new foes . One of the earliest engagements that demonstrated the skill of the clone SCUBA troopers was the Battle of Mon Calamari : the Quarren Isolation League had joined forces with the CIS and its powerful droid army , exacerbating the longstanding tension between the Quarren and the Mon Calamari race into a civil war which the Republic chose to intervene in on behalf of the still loyal Mon Cal people . Under the command of Jedi General Kit Fisto , several " Acclamator " - class assault ships descended on the planet and an army of clone SCUBA troopers followed Fisto into the Mon Calamari sea where they met the droid army in battle . The aquatic soldiers engaged battle droids on foot and on mini - sub mounts , bringing down numerous manta droid subfighter s and at least one Separatist Sub - Carrier . The battle soon turned in favor of the Republic when General Fisto destroyed the Quarren ' s massive " crab cannon " , and with it a significant portion of the battle ' s Quarren leadership . Afterward , Fisto left his SCUBA troops behind on mop - up operations while he personally investigated the presence of the Moappa and instigated negotiations between the newly discovered sentient race and the Mon Calamari . At a point further in the war , circa 21 BBY , Senator Onaconda Farr of Rodia noticed ecological damage and disturbances to his world that he feared was the work of the Confederacy . Requesting a Republic investigation , General Kit Fisto was dispatched to Rodia with a detachment of clone SCUBA troopers . Taking a squad of troopers into the water where the disturbances originated , Fisto ordered another squad of SCUBA troopers to search the surrounding area , led by a SCUBA trooper commander . The commander ' s men were ambushed by battle droids inside of a nearby abandoned Rodian base , but were able overcome the droids and destroy them . In the water , two SCUBA troopers fell to laser cannon fire when the source of the disturbances turned out to be the bounty hunter , Robonino . During the resulting skirmish , the mercenary ' s hideout was destroyed and Robonino managed to escape , only to be delivered into the Jedi Master ' s custody by the grace of luck , courtesy of a native Kwazel Maw . It was also around this point in time that the planet of Mon Calamari came under attack by Confederacy forces for the second time in the war . Directed by the Karkarodon commander , Riff Tamson , the Confederacy again supported the Quarren people in their attack on the Mon Calamari , while several Grand Army units under Jedi Generals Anakin Skywalker and the returning Kit Fisto came to the Mon Cals ' aide . SCUBA trooper clones under the leadership of Commander Monnk found their skills in just as high demand as they had been during the previous battle on the water world , but victory proved harder the second time . The Republic took heavy casualties during the battle , with the SCUBA troopers requiring support and reinforcement from the Gungan Grand Army of Naboo . Even still , it took the death of Confederate leader Tamson at the hands of Mon Calamari prince , Lee - Char , to finally turn the tide away from what seemed like certain victory for the CIS . Equipment . Clone SCUBA troopers were issued specialized clone trooper armor , lighter in weight than the standard armor made up of a plastoid - alloy composite , which was worn by the Grand Army ' s ground infantry soldiers . These unique suits were outfitted with aquatic propulsion packs worn on the trooper ' s back , feet - worn , and maneuverability jets built into the armor ' s shin plates for increased agility while underwater . The SCUBA troopers ' helmets possessed powerful lenses and sensors that allowed the wearer to pierce through potentially murky water and offered a clear image of underwater enemies , though the internal communications system amplified even the slightest breath for anyone on the frequency . The helmets also featured built in miniaturized oxygen scrubbers , able to extract viable air from the surrounding water once the wearer was submerged , though external oxygen tanks could also be attached . This effectively eliminated the need for the wearer to come to the surface for air , allowing SCUBA troopers to remain underwater for lengthy periods of time . Though the SCUBA armor had been developed " for " , and was primarily used " by " clone SCUBA troopers , suits of the armor were also available to members of the Grand Army ' s special forces for use on aquatic missions , and the clone commandos of Delta Squad utilized the armor during their mission to Dorumaa in search of the rogue Kaminoan scientist Ko Sai . Additionally , clone SCUBA troopers were equipped with specialized blaster rifles , similar in design to the clone army ' s standard DC - 15 blaster , that possessed a modified collimator barrel array , responsible for reducing the speed of blaster bolt diffuse in a water environment . SCUBA troopers were also issued explosive ordnance designed to capitalize on water ' s ability to transmit concussive shock . Behind the scenes . Clone SCUBA troopers first appeared in the fifth chapter of the " " micro - series , which first aired in 2003 . Details about these aquatic troops were later provided in the " Star Wars " Databank entry for the SCUBA troopers on StarWars . com , in addition to receiving mentions in " The Complete Star Wars Encyclopedia " and " The Clone Wars Campaign Guide " . SCUBA troopers were mentioned several times in the " Republic Commando " novel , " " by author Karen Traviss , and their armor was utilized by several of the clone commando protagonists . In 2011 , the clone SCUBA troopers would appear in a prominent role again in the opening trilogy of episodes for the of the " " television series , comprised of the episodes " Water War " , " Gungan Attack " , and " Prisoners " . The word " SCUBA " is a real - world acronym , meaning Self - Contained Underwater Breathing Apparatus .
