When Corran Horn (going by the alias Jenos Idanian) infiltrated the Survivors while searching for his wife Mirax, he was placed in Rock Squadron under Kech's command. Kech personally trained Horn in the usage of the Clutch starfighter.
Kech was killed in a pirate engagement against Y-wings and Uglies when the Invidious failed to appear on schedule. Afterwards, "Idanian" was selected to replace him as Rock Lead.
