The Purple Heart medal 
can legally be authorized to only three groups of personnel:
First, those wounded or injured as a direct result of hostile enemy action.
Second, those wounded or injured as a direct result of friendly fire (FF). (Broadly speaking, FF occurs only during a hostile encounter or initiative with, or in response to, an enemy when someone on your side mistakes you for the enemy.) Or when injured by your own non-projectile weapon (bayonet, sword, blunt instrument, etc.) or projectile weapons fire (bullet, explosive device, etc) while engaging, responding to or attacking an enemy.
Third, POWs injured or wounded as a result of individually directed conflict or punishment with their captor in violation of any article of the Geneva Convention Rules of Warfare Concerning the Treatment of Prisoners of War whether or not the captor's government is a signatory to the Convention.
The World War One Victory medal 
can legally be authorized to personnel serving in any military branch in dates 6 Apr 1917 to 11 Nov 1918, even one day.
