The advance production order The NRC set up the Committee on Review of Test Proto was for 1.08 million helmets, and these are in sustainment. cols Used by the DoD to Test Combat Helmets to consider When a manufacturer proposes to produce ACHs for the the technical issues relating to test protocols for military Army, it submits a sample for first article testing (FAT)

The Director of Operational Test and Evaluation should revert to the more transparent and robust analysis of backface deformation data based on pass/fail CONSIDERATIONS IN DEVELOPING NEW PROTOCOLS scoring of each measurement. Although the Army's modified protocol can be a shortterm solution, the committee encourages DOT&E to consider However, it is important to conduct post-test analysis of the the various findings and recommendations in the report and continuous BFD measurements and monitor them over time.
