The psychic sensor is a Soviet defensive structure in Command & Conquer: Red Alert 2, meant to detect incoming enemy movements within a radius around the structure, as well as uncover spies, superweapon markers, and submerged units within the area of effect.
This device was designed by the Soviet Psychic Corps.
|The following is based on the Soviet campaign of Red Alert 2 and might contradict canon.|
However, in the non-canon Soviet campaign, it is implied that the core armed forces were either unaware of the technology, or did not have access to its schematics. During Operation: Red Revolution, Lieutenant Zofia managed to obtain the blueprints for the device and allow its use in the skirmish.
Using unknown means, the psychic sensor is able to predict enemies who would attempt to attack within 15 tiles of the surrounding area. Unlike the unlike its successor from the altered timeline and the Allied spy satellite uplink, it was unable to function as a radar array on its own.
