The Distinguished Service Cross is awarded to a person who while serving in any capacity with the Army, distinguished himself or herself by extraordinary heroism not justifying the award of a Medal of Honor; while engaged in an action against an enemy of the United States; while engaged in military operations involving conflict with an opposing or 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. The act or acts of heroism must have been so notable and have involved risk of life so extraordinary as to set the individual apart from his or her comrades.
