A more thorough explanation:

The Office of Civilian Health and Medical Programs of the Uniformed Services (OCHAMPUS) is a part of the U.S. Department of Defense. Its main responsibility is to provide health and medical care to the spouses and dependent children of active members of the armed forces, as well as retired military personnel and their spouses and children.

For example, if a soldier is married and has children, OCHAMPUS would provide medical care for their family members. Similarly, if a retired military personnel and their spouse need medical care, OCHAMPUS would provide it.

OCHAMPUS is important because it ensures that the families of active and retired military personnel have access to quality healthcare. This helps to support the well-being of military families and allows them to focus on their important roles in serving our country.
