Watershed Division
From Halopedia, the Halo wiki
The Watershed Division is a branch of the UNSC. It was responsible for the manufacturing of the Prefect armor variant. The Prefect variant was the product of research on Trevelyan from the discovery of a native armor system, utilized by Forerunner Prefects late into their civilization’s history. The Watershed Division used local Huragok to reverse-engineer the original designs, grafting the abandoned armor system into baseline MJOLNIR standards for SPARTAN-IV use.[1] It was tested at Denegroth, West Conamara on Europa.[2]
