Final answer:
Military dependents are covered by TRICARE, a health insurance plan for military personnel and their families, retirees, and some former spouses.
Step-by-step explanation:
Dependents of military personnel are covered by the government-sponsored health insurance plan known as TRICARE. TRICARE provides coverage for active duty service members, National Guard and Reserve members, retirees, their families, survivors, and certain former spouses worldwide. This is distinct from other government health care programs such as Medicaid and Medicare. Medicaid provides coverage for people with low incomes, while Medicare primarily offers insurance to people over sixty-five years of age and to individuals with certain disabilities.
