The signature page is structured as standard USMC correspondence consisting of Unit Letterhead, From Line, To line, Via Line, Subject Line, Reference Line, Enclosure Line, Paragraph and Signature Block.

The signature page must be signed. The Commanding Officer’s signature equates his/her affirmation that the content of the Command Chronology is a true account of the command's activities. If not signed by the Commanding Officer, an explanation of non-availability of the Commanding Officer is needed. The signature is a legal requirement.

The organizational data includes the full official Unit Designation, the time period covered, all geographic locations during report period, a listing of principle staff members and subordinate commanders with inclusive dates, and TO&E for both equipment and personnel.
