The US Navy has ordered its entire workforce of 340,000 active-duty personnel, 58,000 reservists, and 210,000 civilian employees—along with their families—to clean up their social media profiles. The guidance warns that adversaries might be using social platforms to determine who they are, where they live, and when they are not at home.
Because this report is based on a single source, there are no independent or conflicting accounts to compare. The move is presented as a defensive response to open-source intelligence gathering, not as a reaction to a specific disclosed incident.
The concern is that ordinary posts, when collected across platforms, can reveal patterns that become strategically useful. The Navy is asking its people to reduce that public exposure before adversaries can assemble a more complete picture.
