What Is OverWatch

Overwatch is the general self-titled name of the Combine's military and police forces on Earth. It is used as the suffix designation of the forces in the various sectors such as Sector 17 Overwatch for City 17 and the surrounding wasteland. The name also explicitly refers to the Combine's automated Command and Control System on Earth, often encountered in the form of the Overwatch Voice. Although primarily made for garrisoning Earth, Overwatch soldiers are hinted to be deployed throughout the Universal Union on various off-world assignments in other territories
