The President may award, and present in the name of Congress, a medal of honor of appropriate design, with ribbons and appurtenances, to a person who while a member of the Army, distinguished himself conspicuously by gallantry and intrepidity at the risk of his life above and beyond the call of duty—
((1)) while engaged in an action against an enemy of the United States;
((2)) while engaged in military operations involving conflict with an opposing foreign force; or
((3)) 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.
