Definition

MilSO (Military Significant Other) is a community term for the unmarried romantic partners of service members. While spouses receive official recognition and support through military family programs, MilSOs often navigate the same challenges — separations, deployments, PCS decisions — without the same institutional support structure. MilSO communities have developed organically, particularly online, to provide peer support, resources, and connection.
