Members of the team volunteers that may be drawn from local response agencies, specialized teams, State (ITTF) sponsored teams, state agencies or in some cases, even the private sector
The purpose of creating IMAT is to provide a valuable resource for state and local Incident Command /Unified Command staff at the scene of an emergency or disaster. IMAT would provide support to the IC/UC in the implementation of the incident command system and specifically in the formation and implementation of the Incident Action Plan (IAP). The purpose of IMAT is to support the incident commander, not assume or divide command authority.
