Terminal Learning Objective
Define the terms used to describe a conventional ammunition malfunction and the responsibilities
of the specific individuals and agencies involved.
You will be given a description of the terms and procedures used in conventional ammunition

You will define the terms and identify the responsibilities of individuals and agencies.
The material in this lesson was derived from AR 75-1, Technical Bulletin (TB) 9-1300-385, and
Technical Manual (TM) 43-0001-28.
As an ammunition officer/operations officer, an ammunition supply point (ASP) commander, or a division
ammunition officer (DAO), you must be aware that ammunition malfunctions will occur when ammunition is in
use, both during training and during combat operations. Since you will be among the first to be notified, you must
be familiar with the terms associated with conventional ammunition malfunctions. You must also know what
actions must be taken by each agency at each organizational level. This lesson will teach you about these terms
DEFINITION OF TERMS
In order to maintain accuracy, it is critical that everyone involved in malfunction investigating and reporting use
the terminology that follows.
A malfunction is the failure of an ammunition item to function as expected when fired or launched, or when the
explosive components of an item function during a nonfunctional test. Malfunctions include misfires, hangfires,
and duds. They also include the abnormal or premature functioning of explosive ammunition items, warheads,
missiles, and rockets during normal handling, maintenance, storage, transportation, and tactical deployment. Not
included are accidents and incidents resulting from negligence, malpractice, or unusual situations (such as vehicle
accidents or fires).
