What defines a "Failure to fire" malfunction?

A "Failure to fire" malfunction is specifically characterized by the weapon's failure to discharge a round when the trigger is pulled. This means that despite following the proper procedures, the weapon does not initiate the firing sequence. This can occur for various reasons, such as a faulty firing pin, poor ammunition, or other mechanical issues. Understanding this malfunction is crucial for soldiers to troubleshoot and resolve issues effectively during training or in combat situations.

The other choices describe different types of malfunctions. For instance, a trigger pull that does nothing when squeezed typically indicates an issue with the trigger mechanism or disconnect, while the weapon firing while on safe points to a serious safety malfunction. A weapon that fires but misfires refers to situations where the round may explode but does not function as intended, which is also distinct from a failure to fire. Each of these scenarios highlights different problems that can occur with firearms.
