United Earth Space Corps

The United Earth Space Corps is a human organization. Fleet Admiral Terrence Hood referred to to Sergeant Major Avery Johnson as "a soldier of the United Earth Space Corps" when awarding him the Colonial Cross. The UESC's relationship to the United Nations Space Command and Unified Earth Government is unclear.

It is likely that this is simply another term for the UNSC, perhaps used in ceremonial occasions to highlight their allegiance to Earth. Alternately, however, it is possible that the phrase particularly refers to the defensive elements of the UNSC specifically tasked with the protection of Earth - this makes sense, as the forces tasked with defending Earth seemed to feature an irregularly high quantity of Marine and Naval assets, in contrast to the UNSC Army and Air Force elements which predominately compose the UNSC Defence Force.

Trivia
The organization's name is inspired by the United Earth Space Council, humanity's governing body in Bungie's Marathon series.
