This legislation, known as the Vietnam Veteran Commemoration Fund Act of 2025, aims to strengthen and extend the Department of Defense's program for commemorating the 50th anniversary of the Vietnam War. It achieves this by amending the National Defense Authorization Act for Fiscal Year 2008, specifically Section 598. The primary modification involves changing the Secretary of Defense's authority from discretionary to mandatory , meaning the Secretary "shall conduct" the commemoration program rather than "may conduct" it. This ensures the program's continuation and execution. Additionally, other subsections are updated to reflect this mandatory nature and clarify the Secretary's role. These amendments are scheduled to become effective on November 11, 2025 .
