Commander Kolana was a female Klingon warrior. She served as weapons officer under General Martok aboard the IKS Ch'Tang in 2375. She had the honor to serve with Dahar Master Kor in his final mission. Awed at first by the legendary warrior, she turned on him after his wits failed him in the raid on Trelka V. Kor won back her respect by sacrificing himself in battle with the Jem'Hadar. (DS9: "Once More Unto the Breach")
