Under the law passed in 1956, who does TRICARE provide medical and hospital care for?

TRICARE is a health care program established to provide comprehensive medical and hospital care for a broad population associated with the military. This includes active duty military members, veterans, and retired military personnel. The program was designed to ensure that these individuals, who sacrifice their time and service for the country, have access to necessary health services.

The inclusion of active duty service members means that those currently serving in the military can receive health care support while they fulfill their duties. Additionally, veterans benefit from TRICARE's services as they transition back to civilian life, ensuring continuity of care. Retired military personnel also receive benefits, reflecting the commitment to support service members even after they leave active duty.

Therefore, TRICARE's comprehensive coverage aligns with the federal law enacted in 1956 to provide for all these groups, which is why the correct response encompasses all of the categories listed.
