Power signature scan

From Command and Conquer Wiki

The Power Signature scan is an intelligence power that was developed by the Black Hand following the Firestorm Crisis. It can detect all enemy Power Plants across the battlefield. As GDI Power Plants are usually placed within their bases, discovering the location of enemy powerplants often results in the discovery of large portions of GDI bases. The AI LEGION used this ability several times during Kane's return to power and beyond when granted control of Black Hand forces.
