Which branch's personnel will require a statement from their inter-service spouse for co-location requests?

The correct answer is the Navy. In the Navy, when personnel are requesting co-location due to marriage to members of other services (inter-service spouse), a statement from the spouse is necessary to support the request. This policy is in place to help facilitate the assignment process so that married couples can be stationed near each other, aligning with the Navy's commitment to family welfare.

In contrast, other branches may have different requirements or procedures for co-location requests, or they may not require a statement from the inter-service spouse specifically. Each branch has its own regulations governing assignments, and while they may aim to support service members' families, the specific requirement for a spouse's statement as part of the co-location request process applies distinctly to the Navy.
