The Department of Defense Medal for Distinguished Public Service is the highest award that is presented by the Secretary of Defense, to a private citizen, politician, non-career federal employee, or foreign national. It is presented for exceptionally distinguished service of significance to the Department of Defense as a whole, or a DoD Component or function, where recognition at the component level would not be sufficient for the service rendered.
