CT-43/002 was a clone trooper and member of The Muunilinst 10, a group of elite Advanced Recon Commandos that participated in a battle on the planet Muunilinst in 22 BBY during the Clone Wars. The commandos were tasked with capturing a Confederate artillery emplacement, but the clones' LAAT/i gunship was shot down by a B1 battle droid, and battle droid assassins opened fire at the clone trooper survivors of the ship's crash. In the ensuing firefight, CT-43/002 was killed; however, the rest of the squad survived the droid attack and eventually completed their mission without sustaining any more casualties. Later, The Muunilinst 10 leader, Captain ARC-77, transferred his Chancellor's Service Medal to CT-43/002 posthumously.
