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.
