This article is about the UNSC Prowler engineer. For the Navy technician aboard the Pillar of Autumn, see Cho (Navy technician).
As of 2552, he was technically past the mandatory retirement age for the UNSC Prowler Corps, which was quietly ignored by his commander, Captain Iglesias, as Cho was an extremely skilled engineer and impossible to replace.
Cho was at his post in late 2552 during the Battle of Earth. Commander Richard Lash took the ship into slipspace in pursuit of the Prophet of Regret's assault carrier the Solemn Penance, which was being pursued by the UNSC In Amber Clad. Cho stayed at his post on the trip to Installation 05, back to Earth and then to Onyx and the Onyx Conflict, and then back to Earth again.
