For Special Access Programs (SAP), which marking is typically used?

The designation "Special Access Required" is used specifically for Special Access Programs (SAP) to indicate that access to this information is restricted to individuals who have the appropriate clearance and a need to know. This marking is crucial as it informs personnel that additional security measures are in play beyond the standard classification levels of Confidential, Secret, or Top Secret.

It serves to ensure that only authorized individuals can access sensitive compartmented information related to the program, reinforcing the importance of protecting particularly sensitive national security information even more stringently. This marking facilitates the proper handling and dissemination of information associated with these high-stakes programs.

The other markings, while related to classified information in general, do not specifically pertain to the SAP framework or its additional security requirements.
