The Presidential Unit Citation (PUC) is awarded to units of the US Armed Forces and allied nations for extraordinary heroism in action against an armed enemy occurring on or after December 7, 1941. According to the Department of Defense, the unit “must display such gallantry, determination, and esprit de corps in accomplishing its mission as to set it apart from and above other units participating in the same campaign. The degree of heroism required is the same as that which would warrant award of a Distinguished Service Cross to an individual.” Prior to 1957, the PUC was known as the Distinguished Unit Citation.
