Should the SCI control system marking be included in the banner line on a classified document?

The control system marking for Sensitive Compartmented Information (SCI) should not be included in the banner line on a classified document. The primary purpose of the banner line is to communicate the level of classification and any pertinent handling instructions clearly to individuals who may encounter the document. Including SCI control markings could lead to confusion and misinterpretation of the document's compartmentalization and sensitive nature.

Banner lines typically consist of the overall classification level (e.g., Confidential, Secret, Top Secret) along with relevant caveats, but do not delve into the specific compartmentalization of SCI. This is to ensure that the information remains compartmentalized and is shared only with those who possess the proper clearance and need-to-know. By refraining from including the specific SCI markings in the banner line, it helps maintain the integrity of the compartmentalization and adheres to security protocols governing the handling of sensitive information.
