What does "firing" represent in the cycle of function?

In the context of a cycle of function, "firing" specifically refers to the release of the projectile. This action is a critical phase in many mechanical systems or processes, particularly in firearms, where firing determines the performance and outcome of the mechanism. Once the projectiles are loaded, the firing mechanism engages, initiating the release where propellant ignites and enables the projectile to be propelled forward.

Understanding firing as the release of the projectile clarifies its significance within the entire cycle. It is a definitive action that impacts subsequent phases, such as ejection and reloading. Examining this definition underscores why firing is not associated with loading, extraction, or reloading processes, which occur at different stages and serve varying functions in the overall cycle.
