The Distinguished Unit Citation was established by Executive Order No. 9075, on February 26th 1942. This order made it possible for the Secretary of War to issue citations in the name of the President of the United States to units of US Armed Forces and their Allies for heroism in action against an armed enemy from December 7th 1941 onwards. The unit must display such gallantry, determination, and esprit de corps in accomplishing its mission under extremely difficult and hazardous conditions as to set it apart and above other units participating in the same campaign. This act should be equal to that of an individual who could obtain the Distinguished Service Cross for it.
