Security-Chief was the Kzinti Chief of Security of Federation Installation Nine. Security-Chief is his given name. Little is known about Security-Chief's personal life, spending most of his off duty hours in his quarters. D'Sefet did introduce him to the station's holosuite. They went on an unarmed hunt in Africa there killing a Cape Buffalo with their bare claws. The head of the Buffalo hangs as a trophy in Security-Chief's office on FI-9.
