From Liquipedia StarCraft 2 Wiki


Sight or Vision is an attribute of units and structures that allows players on the same team to see enemy units or structures, or to reveal things through the Fog of War. Every unit or building provides vision of a certain distance, and this vision continues to be provided for a brief time after the unit or structure blinks, is warped, or is destroyed. Areas with sight or vision are shown on the minimap as well as the main window. Units which are provided sight are able to attack units that they could not see on their own.

Ground units cannot see up cliffs. A scan will also reveal highground terrain.

Detection is a separate ability. Although detection is tied to a unit's sight range, it will provide detection within that range when its own line of sight is blocked by terrain or sight blockers as long as vision is provided by another unit.

Sight Ranges[edit]

Unless otherwise noted, buildings have a sight range of 9. The Radar of the Sensor Tower works slightly differently than other building's sight. It shows the player the position of enemy units, but does not allow ranged units to attack. Burrowed Zerg units have their sight reduced by 4, except for:

The Tempest and the Siege Tank (in siege mode) are notable as being the only units with an attack Range longer than their sight range. For those units to attack at maximum range, some other unit or ability must be used to grant vision of the target.
