What is the portion marking for confidential information from a Special Access Program (SAP) with the code word abbreviation HT?

The appropriate portion marking for confidential information that is part of a Special Access Program (SAP) with the code word abbreviation HT is represented as HT//C. In this marking, "HT" designates the specific code word associated with the SAP, while "C" indicates that the information is classified at the Confidential level.

In this context, the use of the code word in the portion marking serves to indicate that the information is not just confidential but also falls under additional security measures typical of a Special Access Program. The information that is classified under a SAP is subject to stricter distribution controls and access limitations, reflecting its sensitivity.

The selection of HT//C combines these elements effectively, signaling both the classification level and the specificity of the access requirement. This follows the proper marking protocols established for categorized information to ensure that handling and access are consistently maintained in accordance with security standards.
