Acting Navy Secretary Hung Cao directs Sailors, Marines, reservists, civilian employees and military families to hide Department of the Navy ties amid doxing, drone surveillance, cyber threats and suspected physical-security probes.
WASHINGTON | The Department of the Navy has issued an urgent force-protection warning directing personnel and their families to review social media accounts, restrict public access and remove information that could expose their military connections or daily routines.
The Aug. 19 message, titled “Epic Vigilance: Immediate Actions for Force Protection and Personal Security,” describes what Navy leaders characterize as a coordinated, multidomain threat campaign targeting Department of the Navy personnel, installations, warships, aircraft and families.
The Navy’s central message is direct: Personnel and their families should assume that adversaries are collecting publicly available information and combining seemingly harmless details to identify military affiliations, movements and vulnerabilities.
“Adversaries are actively mining this data,” the notice states.
The official ALNAV 050/26 force-protection message does not identify a single triggering incident or name the foreign governments, extremist organizations or individual actors believed to be responsible. Instead, it describes a pattern of activity that naval leaders say has intensified since the beginning of Operation Epic Fury.
Navy tells personnel to remove military connections
The notice instructs personnel to immediately examine every social media account—including accounts belonging to family members—for information visible to the public.
Users are advised to set profiles to private and remove information that could identify a connection to the Department of the Navy. The warning also calls for eliminating posts or profile details that could reveal “patterns of life,” including routines, frequently visited locations, work schedules, travel habits and family activities.
That information can become more dangerous when combined with geotagged photographs, employment histories, deployment announcements, unit affiliations, home addresses, vehicle markings and publicly visible connections to other service members.
The new directive goes further than routine reminders against disclosing classified or operational information. It asks members of the naval community to reduce publicly available evidence of their connection to the service itself when that information could assist hostile targeting.
The guidance reflects a longstanding military concern that adversaries can assemble an operational picture from multiple pieces of unclassified information. The Navy defines operations security, or OPSEC, as the process of identifying and protecting critical information while analyzing how observable activities could be exploited by an adversary.
Earlier Navy guidance has warned that photographs, location metadata, deployment details, workplace images and family information can expose personnel and missions. The service’s official social-media OPSEC guidance notes that even ordinary images may reveal locations, equipment or information about a person’s duties.
Doxing, drones and physical surveillance cited
ALNAV 050/26 identifies five primary categories of concern:
- Direct threats and harassment targeting personnel and families through social media, including the publication of personal information.
- Uncrewed aircraft surveillance near warships, flight lines and critical infrastructure.
- Ground-level surveillance and suspicious activity around military installations and surrounding communities.
- Attempted attacks or probes against access-control points.
- Coordinated harassment intended to test security procedures and personnel endurance across multiple locations.
The warning suggests that Navy leaders are increasingly treating online targeting, drone activity, cyber incidents and physical surveillance as interconnected threats rather than isolated security problems.
The Naval Criminal Investigative Service established Epic Vigilance as a department-wide initiative to detect, deter and mitigate threats to personnel and installations. NCIS serves as the Department of the Navy’s lead agency for counterintelligence investigations and conducts counterterrorism and major criminal investigations affecting Navy and Marine Corps personnel and resources.
The notice instructs members of the naval community not to dismiss unusual behavior simply because an individual incident appears minor. Information that seems insignificant in isolation may help investigators identify a larger surveillance or targeting operation.
Personnel should immediately report individuals who linger near or photograph gates, perimeter fencing, ships, aircraft, military housing or other sensitive locations—particularly when telephoto equipment, concealment or evasive behavior is involved.
The Navy also wants reports of any uncrewed system operating near an installation, pier, flight line or location regularly used by personnel. Nighttime drone activity or operations near sensitive military facilities should receive particular attention.
Additional warning signs include:
- Unusual questions about ship movements, deployment dates, leadership schedules or base operations.
- Aggressive attempts to obtain addresses, telephone numbers, email addresses or social media information.
- Personnel or family members being followed, photographed or confronted away from an installation.
- Threatening or suspicious emails and social media messages.
- Imposter accounts posing as Sailors, Marines or other members of the naval community.
Emergency or life-threatening situations should be reported to 911. Nonemergency incidents may be reported through installation security, local law enforcement, a command force-protection office or NCIS Tips.
Families become part of force protection
The inclusion of spouses, children and other relatives reflects how easily online searches can connect service members to family accounts. A Sailor may maintain strict privacy settings while a spouse publicly posts deployment dates, photographs near military housing or details about an upcoming move.
Family posts may also reveal when a service member is away, where children attend school or which relatives provide care during deployments.
Previous Navy OPSEC guidance has emphasized that military families help protect information that could affect both personal safety and operational readiness. The new notice makes that responsibility part of a heightened department-wide security posture.
Warning is broader than recent Navy controversies
The timing of the force-protection message coincides with public scrutiny surrounding Navy deployments, ship readiness and other leadership decisions. However, ALNAV 050/26 does not connect Epic Vigilance to aircraft-carrier naming discussions, deployment conditions aboard the USS Abraham Lincoln or the reported power failure aboard the USS Benfold.
The notice instead ties the heightened security posture to the threat environment following Operation Epic Fury and to reported incidents involving drones, cyber activity, surveillance, harassment and violence.
That distinction is important: The order is an operational-security and counterintelligence directive, not a public-affairs response to recent controversies.
Cao’s message closes by emphasizing that security depends on collective action across the Navy-Marine Corps team. The warning places responsibility not only on base security and NCIS investigators but also on every person whose online activity could reveal information about naval personnel, operations or facilities.
For Sailors, Marines and their families, the immediate assignment is clear: lock down accounts, reduce identifiable military connections, examine what routine activities are visible online and report suspicious behavior before it develops into a larger threat.
