I am an aunt of a child. Can I use a military card to see a doctor?

I can't. Because the military security card is issued to active-duty soldiers and military-related personnel, including spouses and children of active-duty soldiers and parents and spouses of active-duty soldiers, the aunt of the children is not an active-duty soldier, so the military security card cannot be used. Children's aunts need to bring their ID cards, medical insurance cards and other valid documents to the hospital. Hospitals will provide some preferential policies for specific groups, such as military families, the elderly and the disabled.
