Which publication category contains the statement "COMPLIANCE WITH THIS PUBLICATION IS MANDATORY" on the title page?

The statement "COMPLIANCE WITH THIS PUBLICATION IS MANDATORY" is specifically associated with the Air Force Policy Directive category. This classification of documents establishes mandatory guidance and requirements that must be followed within the Air Force. Policy Directives are designed to communicate significant changes in policy, and they carry the weight of mandatory compliance, emphasizing that the content must be adhered to by all personnel.

In contrast, other publication types such as Air Force Manuals and Air Force Guides may provide useful information and best practices, but they do not carry the same level of mandatory compliance. Air Force Instructions can also contain mandatory elements, but the phrase in question is specifically designated to the Policy Directive, which underscores its authoritative nature in establishing policies that apply across the board.
