Abstract
Abstract A method of defending against a warfare cloud of toxic aerosol utilizes a charged defensive aerosol which is sprayed into the cloud. The defensive aerosol is made of a defensive agent which may be chemically or biologically active. The agent is sprayed through charged nozzles to impart a charge to the aerosol. The charge should be at least several thousands of volts with respect to ground so that particles of the defensive aerosol combine and coagulate with particles of the toxic aerosol to neutralize and cause rapid settling of the warfare cloud.
