The Distinguished Service Cross (DSC) is the second highest military decoration that can be awarded to a member of the United States Army (and previously, the United States Army Air Forces). It is awarded for extraordinary heroism:
While engaged in action against an enemy of the United States;
While engaged in military operations involving conflict with an opposing foreign force; or
While serving with friendly foreign forces engaged in an armed conflict against an opposing armed force in which the United States is not a belligerent party.
Actions that merit the Distinguished Service Cross must be of such a high degree that they are above those required for all other U.S. combat decorations but do not merit award of the Medal of Honor. The Distinguished Service Cross is equivalent to the Navy Cross (Navy and Marine Corps, and Coast Guard when operating under the authority of the Department of the Navy) and the Air Force Cross (Air Force).
