A joint assignment "connotes activities, operations, or organizations in which elements of more than one Armed Forces of the United States, as reflected in joint manpower documents or the Joint Duty Assignment List, perform joint missions under the auspices of the Office of the Secretary of Defense; the Chairman of the Joint Chiefs of Staff; or the commander of a Combatant Command". Service members assigned to or attached to a Joint Task Force as individuals, not members of a specific military service's unit, can be eligible for the DMSM. Members of service specific units are eligible for awards of personal decorations from their parent service. Personnel serving with jointly manned staffs within Allied Command Europe, Allied Command Atlantic, the NATO Military Committee, and military agencies associated with functions of the military or other joint activities as may be designated are also included.
