The purpose of this management advisory is to inform U.S. European Command (USEUCOM) officials responsible for security classification guidance of concerns that we identified during the performance of two oversight projects. Specifically, the USEUCOM security classification guide includes generic guidance and may not include sufficient detail for making classification decisions about the DoD’s Ukraine security assistance mission. Additionally, not all USEUCOM subordinate organizations have their own, command-specific security classification guides. As a result, we observed that personnel within multiple commands in the USEUCOM area of responsibility may not be marking documents with the appropriate level of classification. We conducted the work on this advisory with integrity, objectivity, and independence, as required by the Council of the Inspectors General on Integrity and Efficiency’s Quality Standards for Federal Offices of Inspector General.
