Where would you find the most up-to-date and official copy of DoDD 5160.65?

The most up-to-date and official copy of DoDD 5160.65 can be found on the Washington Headquarters Services (WHS) website because this site serves as an authoritative source for Department of Defense directives and instructions. The WHS is responsible for managing a variety of administrative services for the Department of Defense, including the distribution and publication of official documents, which makes it a reliable reference for obtaining the latest directives.

In contrast, although the Department of Defense Manuals might contain references to various directives, they are not the primary source for the most recent updates. The Library of Congress, while extensive and informative, does not specifically focus on providing the latest Department of Defense directives directly. The Government Printing Office is involved in the publication of government documents but does not necessarily host the most current or official versions of Department of Defense policies and directives like WHS does.
