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.
