WASHINGTON (CNN) — The U.S. Army is recalling more than 16,000 sets of body armor even though the secretary of the Army disagrees with a Department of Defense report that some of the ceramic plates failed testing and might not offer the protection required for troops on the battlefield.

The report by the Department of Defense inspector general’s office, expected to be released officially on Friday, says the Army had flawed testing procedures before awarding contracts to make the armor plates.

“DoD does not have assurance that its body armor provides a standard level of protection,” according to the report.

Army Secretary Peter Geren denied any problems with testing but said the armor is being recalled as a precaution and will be replaced with other plates that are not part of the recall, according to Army officials.
