Terminal Learning Objective
Identify reportable dud and misfire rates, calculate percentages of duds and misfires, and identify
You will be given access to extracts from AR 75-1 and a hypothetical dud or misfire ammunition
You will calculate percentage rates for duds or misfires and determine if a malfunction report is

You do not have to report duds and misfires unless the dud or misfire rate is excessive. As an ammunition
officer/operations officer, you must know when these malfunctions are reportable. This lesson will provide you
with the criteria for dud and misfire reporting. You will also learn how to calculate dud and misfire rates and how
to determine if these dud and misfire rates are excessive.
REPORTING DUD AND MISFIRE MALFUNCTIONS
Use AR 75-1, Appendix B, Table B-1 to determine if the malfunction rate is excessive. If it is, a detailed report is
required. Duds and misfires do not require a preliminary investigation or a preliminary report.
Submit reports for excessive duds and misfires on DA Form 4379-R or DA Form 4379-1-R like other
