FYI - the new National Response Framework document has just been released and is now available. The NRF supersedes the National Response Plan and is intended to serve as a guide for how the nation will conduct incident response. The new name is intended to better align the document and this intent.
DOD is a "full partner in the Federal response to domestic incidents, and its response is fully coordinated through the mechanisms of this Framework." [p.11]
