An officer serving as a clone trooper functioned as a clone medical officer within the Republic Military throughout the Clone Wars, a conflict between the Galactic Republic and the Separatist Alliance.
This clone was a clone medical officer, grown on the planet of Kamino. Their genetic template was the DNA from Jango Fett, a bounty hunter and the clone template for the clone trooper army. As both a clone trooper officer and a medic, this individual was involved in the pan-galactic Clone Wars between the Galactic Republic and the Separatist Alliance. They served on the Kaliida Shoals Medical Center, a Haven-class medical station which provided care to 60,000 injured clone troopers. During the early stages of the war, in the Malevolence Campaign launched against the Republic Navy by the Separatists, the medical officer worked alongside Nala Se, the Kaminoan Chief Medical Scientist who supervised the medical station's operations, when the Malevolence targeted their location.
As the medical station commenced the evacuation of its patients, the officer, after receiving information from Jedi General Obi-Wan Kenobi and Admiral Wullf Yularen, questioned Nala Se about her assessment of the Republic's chances against the Malevolence if reinforcements arrived in time. Nala Se replied that this was their singular hope, and subsequently, the two collaborated on coordinating the evacuation efforts. Upon the arrival of the Malevolence, its initial targets were the escaping Pelta-class frigates, which it successfully destroyed. Jedi Generals Anakin Skywalker and Plo Koon, accompanied by Shadow Squadron, launched an attack on the Malevolence, but suffered the loss of nearly half of their starships. Observing these events, the clone medical officer commented that Skywalker's efforts seemed to have failed due to the loss of his vessels, and suggested to Nala Se that they should evacuate, a proposal she rejected, stating her intention to remain at the station.
Once Skywalker and his forces shifted their focus to the mega-ion cannons of the Malevolence and inflicted critical damage, both the officer and Nala Se observed the results of the engagement. After a fleet of Republic Star Destroyers arrived and pursued the Malevolence, Skywalker and his squadron reassembled at the medical station, where he encountered the clone medical officer and Nala Se. At this time, Nala Se expressed her gratitude to Skywalker for his actions, and engaged in a brief conversation with his Padawan Ahsoka Tano about her master, all while the officer observed.
