Under the provisions of Department of Defense 1348.33-M, the Secretary of Defense has awarded the Defense Superior Service Medal to Lieutenant Colonel William Thomas Mayall, United States Air Force, for exceptionally superior service to the Department of Defense while serving as Special Assistant to the Chairman, Joint Chiefs of Staff, for POW/MIA Affairs from 5 February 1986 to 10 August 1989. While serving in this highly visible, extraordinarily demanding and politically sensitive position, Colonel Mayall’s dedicated and professional efforts contributed to achieving more progress toward resolving POW/MIA issues than in the previous years since the United States withdrew from Vietnam. He was the full time clear and unambiguous voice of reason in dealing with not only the day-to-day issues, but also the frequent events calling for immediate, clear thinking and sound counsel. Colonel Mayall consistently demonstrated mature judgment and a broad understanding of the varied initiatives within and outside the government and was able to tie together these often disparate activities into a unified and practicable policy. He routinely and flawlessly represented to Presidential Emissary to Hanoi and the Chiefs of the Service Staffs in the Interagency for a. In short the U.S. efforts toward bringing many of the POW/MIA issues to closure have met with great success due principally to the immense energy and talent Colonel Bill Mayall has brought to his responsibilities. The singularly distinctive accomplishments of Lieutenant Colonel Mayall reflect great credit upon himself, the United States Air Force, the Office of the Chairman of the Joint Chiefs of Staff, and the Department of Defense.
