Tarag was a 23rd century Klingon who served as a helmsman on the B'rel class bird-of-prey IKS Okrona. In 2287 he was on the bridge when Vixis discovered the Pioneer 10 probe that had drifted into Klingon territory.
While the Okrona was pursuing the USS Enterprise-A towards the Great Barrier, Tarag was able to notice the change in the Enterprise shields enacted by Sybok's alterations. He notified Captain Klaa of the discovery which allowed both ships to pass through the barrier.
Before arriving at the barrier, Morek had maneuvered Vixis into distracting Klaa in an attempt to assassinate both of them. However Klaa had instructed Tarag to strike at the time of the attempt. Using a phaser, Tarag vaporized Morek. (TOS novelization: Star Trek V: The Final Frontier)
