Her only appearance is during the Humane Raid - EMP mission, though she's only heard through the loudspeakers telling the sailors and pilots to defend the ship and kill the intruders. After the protagonists have taken control of the Hydra, she calls for help to Fort Zancudo, who send a squad of fighter jets to shoot down the fugitives. However, the squad (Zancudo Six) is destroyed by the the protagonists. She doesn't appear again in-game.
She behaves similarly to the Fort Zancudo officer during the mission Cargobob, as she tells the soldiers to defend the carrier after the players have been detected.
