What specifically are you looking for? There numerous instructions for different parts of the issue. Co-location, child care, BAH, etc. Some fall under Navy policy, others DOD. Like I said in the other thread, the co-location policy really only exists for Enlisted. The rule there is that once you have spent a year in your current command, you can request co-location with your spouse. Same "geographic location," which may or may not mean same base. I don't know much of anything about the USMC side of it.
