Overwatch

Overwatch is the official government of Earth, created by the Union at the culmination of the 7 Hour War to assume command of the planet.

They are, in appearance, a completely human government - led by Administrator Breen, served by the Overwatch Soldiers and policed by Civil Protection - but in reality they are but a puppet of the Universal Union's will on Earth.

Overwatch's prime directive appears to be maintaining control of the human population, and on higher levels, how to integrate humans into the Union successfully.

Day to day transactions, such as deploying metrocops, are managed by 'Overwatch' herself; a mysterious AI that manages Overwatch's deployments, earning her the nickname 'Dispatch.'
