By virtue of the authority vested in me as President of the United States and as Commander in Chief of the armed forces of the United States, it is ordered as follows:
Section 1. There is hereby established the Vietnam Service Medal with suitable appurtenances. Except as limited in section 2 of this order, and under uniform regulations to be prescribed by the Secretaries of the military departments and approved by the Secretary of Defense, or regulations to be prescribed by the Secretary of the Treasury with respect to the Coast Guard when it is not operating as a service in the Navy, the Vietnam Service Medal shall be awarded to members of the armed forces who serve in Vietnam or contiguous waters or air space, as defined by such regulations, after July 3, 1965, and before a terminal date to be prescribed by the Secretary of Defense.
Sec. 2. Notwithstanding section 3 of Executive Order No. 10977 of December 4, 1961, establishing the Armed Forces Expeditionary Medal, any member who qualified for that medal by reason of service in Vietnam between July 1, 1958, and July 4, 1965, shall remain qualified for that medal. Upon application, any such member may be awarded the Vietnam Service Medal in lieu of the Armed Forces Expeditionary Medal, but no person may be awarded both medals by reason of service in Vietnam and no person shall be entitled to more than one award of the Vietnam Service Medal.
Sec. 3. The Vietnam Service Medal may be awarded posthumously.
