Final answer:
A Sailor in the Navy should include the spouse's orders with the personal request for colocation when married to a service member not in the Navy.
Step-by-step explanation:
When a Sailor in the Navy is married to another armed forces member who is not in the Navy, the document that should be included with the personal request for colocation is b. Spouse's orders. The spouse's orders are essential because they provide verification of the service member's current assignment, and this information is necessary for the Navy to consider when co-locating the service members to ensure both assignments can logically support being stationed together. It's a critical part of the request process to ensure that both members of the armed forces can continue to fulfill their duties while also honoring the commitments of marriage.
