The Duros Allied Army functioned as a military force throughout the Galactic Civil War. During her coming-out ball, Rivoche Tarkin received intelligence from a CompForce trainee regarding an impending CompForce offensive aimed at suppressing rebels embedded within the Duros Allied Army. Rivoche then relayed this crucial data to an Imperial Academy student, Biggs Darklighter, whom she believed associated with individuals of "questionable" loyalties. Following the unsuccessful CompForce operation against the insurgents, Rivoche Tarkin initiated her role as an intelligence operative, acting as a spy on behalf of the Rebel Alliance.
