Update Your DEERS Information

It is essential that you keep information in the Defense Enrollment Eligibility Reporting System (DEERS) up to date for you and your family. DEERS is a computerized database of uniformed service members (active duty and retired) worldwide, their family members, and others who are eligible for military benefits including TRICARE.
