For Reserve component Marines, which occasions require that proficiency and conduct marks be recorded?

The correct answer is associated with specific occasions that mandate recording proficiency and conduct marks for Reserve component Marines. The recording of these marks is particularly significant after completing Temporary Additional Duty (TAD) because the performance during this period is key in assessing the Marine's readiness and qualifications.

When a Marine completes TAD, it provides a unique opportunity to evaluate their performance in a different setting or under different responsibilities, which can differ from their usual roles. This assessment is crucial in maintaining standards and ensuring that the Marine is recognized for their contributions, further development, or areas needing improvement.

In contrast, while annual training and annual reviews are important for tracking overall performance, they do not specify the immediate record-keeping requirement related to TAD. Similarly, the phrasing "To TAD" does not indicate a complete occasion requiring marks to be recorded, as it implies an action rather than a defined milestone for assessment purposes.
