In the United States a Community Emergency Response Team (CERT) can refer to
Sometimes programs and organizations take different names, such as Neighborhood Emergency Response Team (NERT), or Neighborhood Emergency Team (NET).
The concept of civilian auxiliaries is similar to civil defense, which has a longer history. The CERT concept differs because it includes nonmilitary emergencies, and is coordinated with all levels of emergency authorities, local to national, via an overarching incident command system.
