Prosecutor The Prosecutor was an " Acclamator " - class assault ship in the Republic Navy during the Clone Wars . History . Battle of Geonosis . Commanded by Captain Martz , the " Prosecutor " participated in the First Battle of Geonosis . When the clone commandos of Delta Squad successfully managed to sabotage a Separatist " Lucrehulk " - class core ship that was still waiting to launch , a Republic LAAT / i gunship from the " Prosecutor " evacuated the commandos from a side breach in the hull of the enemy warship , and Delta Squad returned to the " Prosecutor " . Capture . After the First Battle of Geonosis , the " Prosecutor " was given the task of defending trade routes in the Corellian sector in 21 BBY . During this assignment , the ship ' s crew managed to intercept important information from a Separatist transmission . The data was later captured by Trandoshans , who had boarded the " Prosecutor " . Most of the clone troopers on board were killed by the intruders , though the sheer number of clones possibly allowed them to keep the vessel from being fully captured for the two weeks that it was out of contact with the Republic . Infiltration . When the " Prosecutor " reappeared two weeks later in the Corbantis system , within the Chaykin Cluster and nowhere near Corellia , on the edge of Confederacy - controlled territory , the highly - renowned clone commandos of Delta Squad were called in to investigate the matter . They found the " Prosecutor " drifting in space , powerless . Using a CR25 troop carrier , they infiltrated the ghost ship via the four starboard heavy proton missile tubes . Their primary objective was to retrieve the four data cores — the flight recorders that would have detected what had happened to the " Prosecutor " and left it hanging dead in space . Each commando was responsible for a single data core . As the commandos entered at their respective ingress points , a sensor jammer was activated and cut off their communication from the tactical coordinator on the CR25 carrier , clone advisor CC - 01 / 425 . As they made their way aft through the labyrinth of catwalks , corridors , and mazes of coolant pipes in the engineering section , the commandos were ambushed by scavenger droids and slavers . Meanwhile , Boss , the commander of Delta Squad , arrived at Sev ' s location and watched helplessly as the trooper was ambushed . He also discovered that many surviving clones were still on the ship . However , the majority of these were later killed by either enemy scavenger droid s or the Trandoshans that had taken control of the ship . To add to the mystery of the " Prosecutor " , Boss found a lightsaber in a service corridor during his mission on the ship . However , instead of the lightsaber lying next to the body of a Jedi , it was found beside a dead clone trooper . He then found a group of three survivors who tried to charge a heavy Trandoshan mercenary when he went to investigate a clone trooper who flew into the room . After a tense fight in which three troopers were slaughtered , Boss continued on . Making his way through damaged corridors while fighting off Trandoshans and aiding surviving clone troopers , Boss rendezvoused with Fixer , rescued Sev from interrogation , and broke Scorch out of a detention cell . After rendezvousing , Delta Squad began encountering droids . Upon reaching the bridge , the Deltas destroyed the sensor jammer . CC - 01 / 425 then accessed the ship ' s systems , providing them with information they needed . The squad then proceeded to one of the ship ' s hangars to destroy the Trandoshan dropship docked there and acting as a command center for the enemy . The situation immediately worsened when a " Lucrehulk " - class Droid Control Ship appeared to salvage the ship , as part of a deal made between the Trandoshans and the Confederacy . Delta Advisor proceeded to send out a distress signal , which was answered by the " Acclamator " - class assault ship " Arrestor " . Battle droid dispensers were sent into the starboard hangars of the " Prosecutor " as the Separatists prepared to claim their prize from the Trandoshans . Delta Squad was deployed to secure several hangars against the incoming wave of Confederate droids , and did so by destroying the hangar shield power regulators . With the regulators disabled , the hangar force fields intensified , preventing more dispensers from entering . Fighting their way through the swarms of battle droids already taking control of the ship , Delta Squad arrived at an automated turbolaser control room where they set the controls to fire on the Droid Control Ship while simultaneously fighting off approaching droids . Together with the newly - arrived " Arrestor " , their combined firepower proved too much for the Separatist ship , which was destroyed . As a result , all battle droids aboard the " Prosecutor " were deactivated .
