Several ordinary parts of military life raise exposure. Moves mean mail and records travel. Deployments mean accounts go unmonitored for stretches of time. Personal information sits in multiple databases. None of this is anyone’s fault. It is simply the pattern thieves exploit.
Federal law provides five protections at no cost. Most people use none of them.
The response shifts from prevention to recovery: documenting the fraud, reporting it at IdentityTheft.gov, and disputing the false information with the credit bureaus. Once you provide an identity theft report, the FCRA requires bureaus to block information that resulted from the theft. When persistent identity theft or the inaccurate reporting that follows it will not clear, it stops being a cleanup task and becomes a matter with a legal path. Prevention, though, is almost always the cheaper fight.
