Rather than physically disabling tactical armored vehicles such vehicles can be rendered equally ineffectual as weapon systems by attenuating or distorting the electromagnetic radiation necessary to their control, communications, and target acquisition ability. This objective can be achieved by blanketing a portion of such vehicles with a rigid polymeric foam within which is dispersed metallic flakes. Upon activation of the foaming system by a proximity fuse foam is generated and ejected from the warhead. The foam expands and solidifies on ports, emitters or receptors of tactical armored vehicle, generally within a second or so after delivery, attenuating or distorting visible, radio-frequency, and microwave radiation sufficiently to destroy the effectiveness of the vehicle. The surface condition of the vehicle is of secondary importance, as chemical adhesion is not relied upon. Accordingly, neither rain nor a light covering of snow or sand will adversely alter the effectiveness of the electromagnetic isolation provided by the foam.
