Ro was an officer in the starfleet of the Galactic Empire who fought in the Galactic Civil War. By the time of the First Order, Ro's prowesses had passed into history, and the commemorative armbands worn by sergeants of the First Order's military bore the officer's name in Aurebesh. General Hux's monitor wore a uniform with the officer's name on it, designating her as a sergeant.
