Krusk was the Klingon fleet commander of the 3rd fleet in the year 2292.
When the 3rd fleet, some 37 warships strong at the time, was destroyed by the Metar in orbit of Bursai IV, he chose ignoble retreat over glorious death and went into an escape pod heading for the planet's surface.
The new colony commander of Bursai IV was informed that, while dragging his whimpering carcass in front of the High Council would complete his dishonor, as the ranking field officer they had the right to gut him like a targ. (TOS video game: New Worlds)
