The Department of Defense is one of the biggest government agencies in respect of the number of different FOIA contacts that it has. 

These include everything from the Marine Corps, the National Security Agency, Defense Health Agency, to the varied worldwide command centres.

Almost of all these have FOIA email addresses where requests can be sent, these are listed below, but some don’t accept requests via email and require them to be made online or posted by snail mail.

The Department says: “The Department of Defense is America’s oldest and largest government agency. With our military tracing its roots back to pre-Revolutionary times, the Department of Defense has grown and evolved with our nation”.
