Anxiety is spreading among defense officials and the military community that the recent theft of federal government data linked to China may affect hundreds of thousands of service members.

Compounding those concerns is the limited information made public by the Office of Personnel Management.

Some military officials believe the recent hack targeting the civilian-run OPM seized information from tens of thousands of Standard Form 86s, which are required for all service members and civilians seeking a security clearance. That includes service members of all ranks, officers and enlisted, in a wide range of job specialties and assignments.

“They got everyone’s SF-86,” one Pentagon official familiar with the investigation told Military Times.
