A dud is defined as which scenario?

• A. Flight motor ignites and misses target
• B. Flight motor ignites but misses target
• C. Flight motor does not ignite, but the missile is ejected from the launch tube assembly, travels a short distance, and then falls to the ground
• D. Flight motor detonates prematurely

Answer: (C)

A dud is a munition that fails to function as designed. For the Stinger, that means the flight motor never ignites. When the motor doesn’t ignite, the missile is effectively inert after ejection from the launcher, may travel only a short distance, and then falls to the ground—exactly the scenario described. That’s why this option is the correct definition of a dud.

If the motor had ignited but the missile still missed, the round did function; it just failed to hit the target. If the motor detonated prematurely, that would be a hazardous misfire rather than a dud.
