Where can personnel find guidelines on what is allowed to be posted according to Operational Security (OPSEC)?

The correct answer is found in AFI 35-107, which provides comprehensive guidance on Operational Security (OPSEC) practices, including what information can be shared publicly. This Air Force Instruction outlines the policies and procedures for protecting sensitive information, ensuring personnel understand the importance of maintaining operational integrity. By adhering to the guidelines set forth in AFI 35-107, individuals are equipped to make informed decisions about the dissemination of information, thus safeguarding ongoing operations and national security.

While After Action Review Documentation, Unit Standard Operating Procedures (SOP), and Department of Defense Directives may contain pertinent information regarding various operational guidelines, they do not specifically focus on OPSEC in the same dedicated manner as AFI 35-107. Therefore, those resources are not considered the primary reference for understanding what can be posted in relation to OPSEC.
