An intelligent agent-accomplished detection and tracking system responsive to sensed characteristics in a cloud of chemical or biological warfare agent(s) dispersed over a geographic area of the earth. The intelligent agent elements of the invention provide an organized and repeated comparison of signal data extracted from overhead dispersed conventional sensors of the chemical or biological agent material and accomplish communication with other agents and the outside world using a common flexible communication language. The intelligent agent elements are disposed in hierarchical arrays having at least lower level, mid level and upper level locations and are inclusive of multiple path forward and feedback agent communications.
