Gaafi (Oracle Code U4-M3418) was a Special Operations Unggoy who fought in the Human-Covenant War from 2540 to 2552. Under the direct jurisdiction of the Covenant High Council, his role was in the infiltration and covert operations preceding direct invasion of a Human settlement. As such, his independence as an Unggoy was greater than most, and he led his own Special Operations squad nicknamed “The Brown Bellies.”
