Overwatch

Overwatch is the general self titled name of the Morum army and officers. It is used as the suffix designation of the forces in the various sectors such as Sector 44 Overwatch for City 44 and the surrounding desert. The name also explicitly refers to the Morum Automated Command and Control System (MACCS), always encountered in the form of the Overwatch Voice. Although made for garrisoning Earth, Shock Soldiers are deployed throughout the Universal Union on various off world assignments in other territories.

Background
The Shock Soldiers were human soldiers commanded by Douglas Artur. During their first fight, the Shock Soldiers were caught by the plague, and needed to be rebuilt as cyborgs to survive the virus. Ever since, Shock Soldiers had their flesh replaced with iron and tubing to survive the disease. This then began the Overwatch.

The Overwatch controlled all of the Earth, corralling every human survivor into the only remaining city where they were strictly controlled, watched and put to work for the Morum's own ends. All of the day to day details of this work is overseen by Civil Protection with the Overwatch forces only ever being called in to deal with heavy resistance whilst manning outposts and checkpoints beyond the city limits. The outside street is heavily patrolled using aerial UFOs, battleships, forcefields and outposts to restrict access.
