AD/MIL state of residence will never change unless the service member goes to their local personell office and completes DD Form 2058. See https://home.army.mil/stuttgart/application/files/1415/4712/5692/HRSLR.pdf for details on what is usually required to change one's SLR or HOR, which are basically saying the same thing, different ways.
SLR - State of Legal Residence - Usually applies to military spouses
HOR - Home of Record - Applies to active duty military.
Domicile - same as above
