Republic Outland Regions Security Force The Republic Outland Regions Security Force , abbreviated ORSF and sometimes referred arrogantly as the Republic Navy by its members , was a Planetary Security Force operating out of Eriadu in the Outer Rim Territories in the last decades of the Galactic Republic . The military force was established to reign in the lawless regions in the Outer Rim and was formed by Governor - General Ranulph Tarkin of the Seswenna sector from the Seswenna Defense Forces and the Planetary Security Forces of neighboring sectors . History . Formation . The Ruusan Reformation s disbanded the Republic ' s centralized armed forces and set limits on the strength of the Planetary Security Forces . By the last century of the Republic Classic era , this had led to much of the Outer Rim being effectively abandoned to lawlessness and instability . The crumbling of order concentrated power in the region ' s most populous and prosperous systems , of which Eriadu in the Seswenna sector was the most powerful . Dominated by the Quintad , five powerful families which included the Tarkins , Eriadu became and industrial powerhouse and the headquarters of Quintad Orbital Manufacturing ( QOM ) , a major military shipbuilding corporation . By 57 BBY , QOM was led by Ranulph Tarkin , a fifty - year - old veteran of the Seswenna Defense Forces who had led a successful campaign against the Delmaasi pirates in 66 BBY before his business career . Tarkin was alarmed by the breakdown of order across the Outer Rim , and turned over control of QOM to his cousin to return to his military career . At Tarkin ' s urging , Seswenna ' s senator , Ulm Brashere , convinced the Supreme Chancellor to appoint him Governor - General of the sector , responsible for its defense forces . Given his wish , the now - General Tarkin began to strengthen Seswenna ' s military capabilities by building new warships in QOM ' s own facilities , but this soon fell afoul of the Ruusan Reformations ' restrictions on capital ship strength and size and earned Tarkin the unwelcome attention of Judicial Forces inspectors . Frustrated , Tarkin turned to other shipbuilding companies with which QOM had forged ties , striking lend - lease deals that placed dozens of foreign - made corvettes , frigates and cruisers under Eriadu ' s control . Such " demonstration fleets " were common in the Core Worlds , but Tarkin ' s ambitions in the Rim alarmed the Judicials , and his next actions did nothing to allay their fears : Tarkin struck mutual - defense pacts with neighboring sectors , trading economic assistance for agreements to combine military forces in times of need , share navigational data among their Planetary Security Forces , and treat their sectors as a single theater of operations known as the Greater Seswenna . Tarkin then looked further afield , seeking agreements with other sectors to exchange navigational data and allow safe passage by mutual consent . At a stroke , Tarkin had turned a disorganized collection of Planetary Security Forces into a regional military power , which he proclaimed the Republic Outland Regions Security Force . Controversy . The ORSF ' s rapid expansion bred fears of empire - building on Coruscant . Outraged by accusations of disloyalty , Tarkin stood down as Governor - General in place of his cousin Garvedon and was elected Seswenna ' s senator in 54 BBY . As the Seswenna sector ' s representative to Coruscant , Tarkin became an articulate proponent of enhancing the Republic ' s military capabilities , using the Outland Regions Security Force as a model . His feud with the Judicial Department continued , though the ORSF had many sympathizers within the Judicial Forces , and all the while Tarkin swore that he would turn over control of the ORSF to the Republic government , provided the force was part of a restored , centralized Republic Military . Tarkin became the leader of the Militarist faction of the Galactic Senate , but the suspicions of his detractors deepened . Senators such as Finis Valorum noted the all - Human composition of the ORSF , which struck many as speciesist , and also accused Tarkin of effectively buying the acquiescence of Eriadu ' s impoverished neighbors , seeing sinister designs in the fact that the ORSF referred to its expanded theater of operations as the Greater Seswenna . In reaction , Tarkin and personnel of the ORSF came to refer to their fleet and ground forces as the " Republic Navy " and the " Republic Army " , seeing it as a template for a restored force . The test of battle . The Outland Regions Security Force was put to the test during the Stark Hyperspace War of 44 BBY . The pirate Iaco Stark had been raiding Trade Federation convoys , intensifying a bacta shortage . Tarkin urged the Judicials to hunt down and destroy Stark , threatening that if they would not , the ORSF would . However , the Senate heeded Finis Valorum ' s advice instead , calling a peace conference . Tarkin wrung the location of the peace conference , Troiken , out of Nute Gunray of the Trade Federation . To send the ORSF to a planet on the other side of the galaxy to Eriadu would be a major violation of defense fleet mobility regulations , but Tarkin banked that a major victory over Stark ' s pirates would make him a hero and override legal concerns . Sympathetic Judicials lent the ORSF several battalions of special forces assault troops to provide a ground assault force . When the peace conference began , Gunray signaled the ORSF from his mechno - chair , and Tarkin was too eager to analyse the navigational data . Suspecting treachery , however , Iaco Stark had piggybacked Gunray ' s transmission with a navcomputer virus known as a Tionese program . By the time the ORSF mustered , every navigation computer was infected with the virus . Only one - third of the force reached Troiken ; another third emerged from hyperspace off - course , while the last third emerged from hyperspace in places that would destroy them , such as within planets or near black holes and stars . In the ensuing First Battle of Qotile , the fleet was trounced . The survivors went to ground on the surface of Troiken , rescuing Valorum , Gunray , and their Jedi escorts and digging in at Mount Avos . There , the Judicials ' Special Tactics trooper s fought several battles before the siege was lifted with the Stark Commercial Combine ' s defeat by the Trade Defense Force in the Fifth Battle of Qotile . Ranulph Tarkin was killed in the fighting , but thereby became a martyr to the Militarist cause . Legacy . The Outland Regions Security Force endured after its founder ' s death . Following the Battle of Naboo the ORSF was reinforced with impounded Trade Federation vessels , including cargo haulers , heavy munitions cruisers , C - 9979 landing craft , B1 battle droids , and Vulture droids . In 29 BBY , Wilhuff Tarkin , Ranulph ' s nephew and formerly lieutenant governor of Eriadu , held the rank of Commander within the Outland Regions Security Force . That year , the Security Force launched an unsuccessful attack on Zonama Sekot in an effort to claim a Sekotan starship . A legacy of the ORSF ' s expansion under Ranulph Tarkin was revealed a generation later during the Separatist Crisis . In 26 BBY it responded half - heartedly to a raid by Nocto pirates on Ochotl Ag in the neighboring Airam sector . Ochotl was an agriworld that was affiliated with the Corporate Alliance to better compete with the Eriadu - dominated agricultural firms in the Pangarees , and the ORSF ' s inaction convinced many that it was just a tool of Eriadu ' s interests . The entire Airam sector thereafter seceded from the Republic and joined the burgeoning Confederacy of Independent Systems . Likewise , Eriadu ' s militarism and Tarkin ' s ambition had pushed its rival Sullust and the Rimward sectors of the Rimma Trade Route towards the CIS . During the Clone Wars , Eriadu became a besieged Republic salient within Separatist space . The Outland Regions Security Force fought alongside clone troopers as part of the Republic ' s Eighteenth Army under the command of Wilhuff Tarkin , now one of the first Moffs , and his younger brother Gideon . The Greater Seswenna became the official name of the Eighteenth Army ' s theater of operations , and the ORSF was deployed in engagements along both the Hydian Way and the Rimma Trade Route in the final actions of the Outer Rim Sieges . Organization . Styling himself a General , Ranulph Tarkin bombastically referred to his fleet as the Republic Navy and his ground troops as the Republic Army ; although both had been eliminated by the Ruusan Reformation , his Militarist faction sought to reestablish them . Tarkin ' s detractors noted that the ORSF was composed almost entirely of Humans , which struck many as speciesist . Tarkin insisted that this reflected a concern for unit morale and a desire to standardize systems and procedures . Either by result or intent , most of Tarkin ' s soldiers agreed with his Humanocentric ideals . Personnel . Tarkin ' s soldiers , officers , and vehicles and vessels were culled from the regional defense forces of planets sympathetic to his cause , among them Rendili , Commenor , Eriadu , Barkhesh , and Carida . Soldiers in the force included Antidar Williams and Jace Dallin , the latter of whom served as Ranulph Tarkin ' s aide and bodyguard . Maarisa Zsinj , the mother of future Imperial Grand Moff and Warlord Zsinj , served as an admiral in the Outland Regions Security Force and her skills earned her the nickname of " Ace of the Spacelanes . " Equipment . Tarkin ' s ships were apparently Judicial Forces surplus , and consisted of Corellian Star Shuttles , " Consular " - class space cruisers , and variants of " Consular " s built with wider hulls ( presumably for carrying ground forces ) . The fleet ' s flagship , " Invincible " , was another modified " Consular " . The fleet ' s starfighter force was filled by A - 6 Interceptor s . This force mix reflected traditional military thinking that quick and maneuverable weapons platforms could outfight larger warships . Tarkin ' s ground forces ' primary weapon was the A280 blaster rifle . Behind the scenes . The Outland Regions Security Force was created by Greg Bear and first featured in the novel " Rogue Planet " . The 2012 guide book " The Essential Guide to Warfare " later retcon ned a Republic - affiliated paramilitary force that appeared in the 2001 comic arc " " as being the Outland Regions Security Force .
