Presidential Unit Citation ( United States ) The Presidential Unit Citation ( PUC ) , originally called the Distinguished Unit Citation , is awarded to units of the United States Armed Forces , and those of allied countries , for extraordinary heroism in action against an armed enemy on or after 7 December 1941 ( the date of the Attack on Pearl Harbor and the start of American involvement in World War II ) . The unit must display such gallantry , determination , and " esprit de corps " in accomplishing its mission under extremely difficult and hazardous conditions so as to set it apart from and above other units participating in the same campaign . Since its inception by Executive Order on 26 February 1942 , retroactive to 7 December 1941 , to 2008 , the Presidential Unit Citation has been awarded in such conflicts as World War II , Korean War , Vietnam War , Iraq War , and the War in Afghanistan . The collective degree of valor ( combat heroism ) against an armed enemy by the unit nominated for the PUC is the same as that which would warrant award of the individual award of the Distinguished Service Cross , Air Force Cross or Navy Cross . In some cases , one or more individuals within the unit may have also been awarded individual awards for their contribution to the actions for which their entire unit was awarded a Presidential Unit Citation . Creation and official format . Army and Air Force . The Army citation was established by on 26 February 1942 , superseded by Executive Order 9396 on Dec . 2 , 1943 , which authorized the Distinguished Unit Citation . As with other Army unit citations , the PUC is in a larger frame than other ribons , and is worn above the right pocket . All members of the unit may wear the decoration , whether or not they personally participated in the acts for which the unit was cited . Only those assigned to the unit at the time of the action cited may wear the decoration as a permanent award . For both the Army and Air Force , the emblem is a solid blue ribbon enclosed in a gold frame . The Air Force PUC was adopted from the Army Distinguished Unit Citation after the Air Force became a separate military branch in 1947 . By Executive Order 10694 , dated Jan . 10 , 1957 the Air Force redesignated the Distinguished Unit Citation as the Presidential Unit Citation . The Air Force PUC is the same color and design as the Army PUC but slightly smaller , so that it can be worn in alignment with other Air Force ribbons on the left pocket following personal awards . The Air Force PUC is the only Air Force unit citation enclosed in a gold frame . As with the Army , all members of a receiving unit may wear the decoration while assigned to it , but only those assigned to the unit at the time of the action cited may wear the decoration as a permanent award . The Citation is carried on the receiving unit ' s colors in the form of a blue streamer , long and wide . For the Army , only on rare occasions will a unit larger than battalion qualify for award of this decoration . Navy and Marine Corps . The Navy citation is the unit equivalent of a Navy Cross and was established by on 6 February 1942 . The Navy version has blue , yellow , and red horizontal stripes , and is the only Navy ribbon having horizontal stripes . To distinguish between the two versions of the Presidential Unit Citation , the Navy version is typically referred to as the " Navy and Marine Corps Presidential Unit Citation " while the Army and Air Force refer to the decoration simply as the Presidential Unit Citation . These are only worn by persons who meet the criteria at the time it is awarded to the unit . Unlike the Army , those who later join the unit do not wear it on a temporary basis . Special Clasps .

Eisenhower on January 10 , 1957 ) , and amended by Section 74 of Executive Order 13286 ( signed by President George W .
