10 USC 8750 - Airmans Medal: award; limitations

(1) The President may award a decoration called the Airmans Medal, of appropriate design with accompanying ribbon, to any person who, while serving in any capacity with the Air Force, distinguishes himself by heroism not involving actual conflict with an enemy.
(2) The authority in paragraph (1) includes authority to award the medal to a member of the Ready Reserve who was not in a duty status defined in section 101 (d) of this title when the member distinguished himself by heroism.
