This individual, a human male, held the rank of officer and was stationed on the Steadfast, a Resurgent-class Star Destroyer, throughout the war that pitted the First Order against the Resistance.
In the course of the crucial battle fought on Exegol, the officer observed a group of Resistance fighters aiming their attacks at the navigation tower. This tower was essential for enabling the Sith Eternal's fleet, known as the Final Order, to depart from Exegol. He subsequently relayed this information to Admiral Frantis Griss and Allegiant General Enric Pryde, who then instructed the officer to reroute the origin point of the navigation signal to the Steadfast.
Andrew Havill portrayed the officer in Star Wars: Episode IX The Rise of Skywalker, released in 2019. The film's end credits validate his participation in the role.
