One of the primary factors to consider when contemplating a military-couple marriage is if both members are in the same service. Obviously, it's easier for the services to assign couples together when both are in the same branch. For one thing, it takes less coordination, as only one branch assignment division is involved. Also, remember that I said the services will not create a job-slot just to assign couples together? Well, there just ain't that many Air Force airmen assigned to Marine Corps bases, nor many Marines assigned to Air Force Bases. Additionally, there aren't that many Air Force bases and Marine Corps bases that are close together. So, marrying someone in your same branch of service obviously increases your chance of a successful JOIN SPOUSE assignment.
