The State of Vietnam Friendship Ribbon (aka State of Vietnam Ribbon of Friendship, Vietnam Presidential Unit Citation, and Republic of Vietnam Presidential Unit Citation) with gold frame, was awarded to the U.S. Military Assistance Advisory Group, Indo-China, and other units who during August and September 1954 participated in humanitarian assistance to Vietnam. The award was approved for wear by the U.S. Department of the Army, General Orders No. 16, on February 28, 1955, which required that those wearing it on their uniforms remove it prior to departure from the area.
U.S. Navy personnel who are eligible for the Vietnam Presidential Unit Citation may wear the award. No Marine Corps personnel, however, are eligible for this award.
According to the U.S. Coast Guard, the Republic of Vietnam Presidential Unit Citation was also awarded throughout the war to certain U.S. military units deemed to have performed exceptional service to Vietnam. However, the RVN PUC is not mentioned in the 1967 RVN awards manual nor the Department of the Army Pamphlet DA 672-3 (Unit Citation Credit) as an authorized unit award.
