Initial systems are said to have had limited capabilities that only masked millimeter wavelength microwaves and later, infrared signatures. More recent systems are more powerful, and are capable of masking signatures in the visual range of the electromagnetic spectrum. The system works by utilizing a rapidly oscillating laser screen to project some sort of distortion around the concealed object. Specific details are not described, but has shown adaptability to sudden and violent changes in ambient conditions and the ability to see out from within the concealment, making the system suitable for combat deployment. The view from within an ECS field is washed out and tinged in violet and red.
