National Response Framework and US Army Terrorism Guide

The National Response Framework provides a comprehensive, national, all-hazards approach to domestic incident response. The Framework presents an overview of key response principles, roles and structures that guide the national response. It describes how communities, States, the Federal Government and private-sector and nongovernmental partners apply these principles for a coordinated, effective national response.

A poster over at Daily Kos has written an excellent two part summary of the framework: Part I and Part II. Any thing I would write would be duplicative and I recommend you read these posts over (Daily Kos is political site but some things go beyond politics and this topic is one).

Finally, another reference you may want to examine is the US Army Guide to Terrorism in the 21st Century.
