With the establishment of the Legion of Merit award, the Purple Heart was no longer awarded for meritorious service. By Executive Order 9277, dated December 3, 1942, the award was to only be given for wounds received. Additional Executive orders added circumstances where the award can be given. In 1962 it was ordered the medal could be given posthumously (after the person died). A 1984 change allowed the award to be given for wounds recieved as a result of terrorist attacks or while serving as part of a peacekeeping force. In 1986 public Law 99-145 authorized the award for wounds received as a result of friendly fire.
