A member can request a split tour reassignment after what event?

A member can request a split tour reassignment after serving 24 months at the same activity because this period is designed to ensure that personnel gain sufficient experience and continuity in their assigned duties. This longevity in service at a given activity allows them to contribute effectively, build professional relationships, and understand their role comprehensively.

The split tour reassignment process recognizes the need for personnel rotation while balancing mission requirements and individual career progression. Furthermore, the policy aims to provide members with opportunities to broaden their experiences and skills by moving to new assignments after they have completed a significant duration in one location.

The other options do not meet the established threshold for requesting a split tour reassignment because 12 or 18 months may not provide adequate time for a member to fully develop in their role or for the command to assess their performance and readiness for new challenges.
