A wild fire defense system network for proactively defending homes and properties from wild fires. A GPS system provides GPS-location services to each system component in the wild fire defense system network, supported by a wireless communication network. First and second group of wireless GPS-tracked anti-fire (AF) chemical liquid spraying systems are provided. The first group of wireless GPS-tracked chemical liquid spraying systems are assigned to homes and/or buildings in strategic areas of a specified region, for spraying the outside of homes and surrounding ground cover with environmentally-clean anti-fire chemical liquid, to proactively protect the homes and surrounding ground cover from wild fire. The second group of GPS-tracked chemical liquid spraying systems are assigned to operators in the strategic area for spraying GPS-specified ground cover with anti-fire chemical liquid to create strategic clean-chemistry fire breaks that proactively protect GPS-specified property cover from wild fire. First and second groups of wireless mobile computing systems are deployed with mobile applications installed and configured for receiving messages and instructions from a command center operably connected to the wireless communication network. The command center sends instructions to home owners and/or specified contractors to apply environmentally-clean anti-fire chemical liquid to GPS-specified homes and surrounding areas. The command center also sends instructions to operators to apply environmentally-clean anti-fire chemical liquid to GPS-specified regions to create and/or maintain strategic chemical fire breaks in the region. By virtue of the present invention, the wild fire defense system network is capable of proactively defending homes and properties against wild fire, prior to arrival, by spraying homes and property with environmentally-clean anti-fire chemical liquid using wireless GPS-tracked spraying chemical liquid systems.
