These Klingon crewmembers served aboard Kruge's Bird-of-Prey until their death in 2285.
They've operated several consoles on the bridge and were later part of the boarding party which beamed over aboard the Enterprise to take over the command. Noting the auto-destruct sequence too late they've died during the ship's explosion. (Star Trek III: The Search for Spock)
When the gunner scored what he called "a lucky shot" and destroyed the Grissom, Kruge pulled out his disruptor and vaporized the gunner because he had wanted prisoners. (Star Trek III: The Search for Spock)
This Klingon officer was part of Kruge's away team to the surface of the Genesis Planet. He was present when the Klingon sergeant killed David Marcus and was killed himself when the planet destroyed itself. (Star Trek III: The Search for Spock)
After the untimely death of the first gunner, this officer was promoted to the position.
When engaging the USS Enterprise, he was notably more careful to follow Kruge's instructions to disable and not destroy the vessel.
The gunner was later part of a boarding party sent to secure the Enterprise and was killed when the ship's commander, Admiral James T. Kirk activated the ship's self-destruct sequence. (Star Trek III: The Search for Spock)
This Klingon sergeant accompanied Kruge down to the Genesis Planet where they took the surviving members of the research team prisoner along with the newly-regenerated Spock. When Kruge ordered the sergeant to kill one of the prisoners, the sergeant picked Saavik, though when David Marcus attacked him, he killed Marcus instead by stabbing him into his chest. The sergeant was later shot by James T. Kirk via phaser. (Star Trek III: The Search for Spock)
