Official - Adjective. 1  As an adjective, official often, but not always, means pertaining to the government, as state employee or having state recognition, or analogous to governance or to a formal (especially legally regulated) proceeding as opposed to informal business.
Tricare (styled TRICARE), formerly known as the Civilian Health and Medical Program of the Uniformed Services (CHAMPUS), is a health care program of the United States Department of Defense Military Health System.
TRICARE provides health coverage for active duty and retired service members, their families, and survivors. TRICARE is run by the Department of Defense (DoD). CHAMPVA is a VA health program. These two programs are often confused. This confusion is made worse by the fact that TRICARE used to be called CHAMPUS.
