Defense Casualty Analysis System public casualty-data disruption

The Defense Department’s public Defense Casualty Analysis System appeared to remove four U.S. service-member deaths from its Operation Epic Fury figures in July 2026. Pentagon officials initially attributed the discrepancy to temporary website data anomalies. The deaths subsequently appeared under a new Overseas Operations category, which the department said covered renewed fighting after Epic Fury ended. Reporting later raised separate questions about the completeness of the overall casualty count; a continuing technical outage or cyber cause has not been established.
