Who is eligible for coverage under CHAMPUS?

The correct choice identifies that family members of active duty and retired military personnel are eligible for coverage under the CHAMPUS (Civilian Health and Medical Program of the Uniformed Services). This program was designed to provide health care benefits to the family members of service members, which includes spouses and children. It also extends to certain cases involving retired personnel, ensuring that these families have access to necessary medical services.

This inclusion of family members acknowledges the significant role they play in the military community and the necessity of providing support to them. As service members often face challenges that affect their families' health and well-being, it is crucial that they have access to comprehensive health care coverage.

In contrast, eligibility is not limited solely to active duty personnel or any specific group, such as the elderly or dependents of deceased military personnel, making the other options incorrect. The emphasis on broad coverage ensures that all family members, regardless of the service member’s status, receive essential health care support.
