Transition Service Officers (TSOs) conduct or participate in pre-discharge transition assistance briefings, the Disability Transition Assistance Program (DTAP), the Transition Assistance Program (TAP), review service treatment records, and confer with Department of Defense and Department of Labor facilitators and other participants in the discharge process. The TSO program also allows DAV to assist service members in the development of evidence, completion of required applications and prosecution of claims for veterans benefits administered under federal, state and local laws.
