In terms of gunnery qualifications, what does “annual” denote?

The term "annual" in the context of gunnery qualifications signifies that the requirements are assessed each year. This means that individuals must undergo evaluations or training at least once every calendar year to effectively maintain their skills and compliance with established standards. Regular assessment is crucial in gunnery to ensure proficiency and readiness, as it allows individuals to stay current with any changes in procedures, standards, or technologies that may occur over time.

In contrast to the other options, the idea of "evaluation every quarter" suggests a more frequent assessment schedule than what "annual" implies, while "recertification every three years" indicates a much longer timeframe that does not align with the concept of annual assessments. Lastly, "testing that occurs bi-annually" falls between annual and less frequent options, but does not meet the criteria of being annually assessed as required. Thus, option C accurately captures the meaning of "annual" in this context.
