Brionelle held the rank of admiral within the Chandrilan Security Force in the time of the Old Republic. In the Cold War that occurred between the Galactic Republic and the reborn Sith Empire, Brionelle's duty was as the commanding officer of the Chandrila Orbital Station. During the Sith assault targeting the station, Admiral Brionelle met their end. In remembrance, the Brionelle Memorial Military Academy was subsequently given Brionelle's name.
