Which of the following is NOT included in the cycles of function when using a weapon?

The correct choice indicates that "clearing" is not included in the cycles of function when using a weapon. The cycles of function primarily consist of essential mechanical processes that a firearm undergoes during operation, typically including feeding, chambering, and firing.

Feeding refers to the mechanism that brings ammunition into the chamber from the magazine. Chambering is the process of moving the round into the chamber and aligning it for firing. Firing is the actuation of the trigger that ignites the round and propels the bullet.

While "clearing" is an important procedure that may be done for safety or maintenance purposes—such as removing a malfunctioning round or ensuring the weapon is safe to handle—it does not form part of the operational firing cycles as defined in standard weapon function terminology. Instead, "clearing" is a step taken outside of the fundamental cycle of operations.
