When can a coast selection be 'banked' upon transfer from Japan, Guam, or Korea?

Banking a coast selection essentially refers to the ability to retain a specific duty assignment or preference upon transfer from certain duty stations. In this context, it is established that coast selections cannot be banked when transferring from Japan, Guam, or Korea. This policy is likely in place to maintain operational readiness and to ensure that personnel are assigned in a manner that meets the needs of the service.

Service requirements and the unique operational environments in these regions can influence assignments, making it crucial that members transition based on the current demands of their roles rather than retaining previous preferences or selections. By not allowing coast selections to be banked, the military ensures a more streamlined and efficient assignment process that prioritizes mission readiness and effectiveness over individual service member preferences.
