Purple Heart - a United States military decoration awarded to those wounded or killed while engaged in combat. The Purple Heart differs from most other decorations in that an individual is not recommended for the decoration; rather he or she is entitled to it upon meeting specific criteria. A Purple Heart is awarded for the first wound suffered under combat conditions, but for each subsequent award an oak leaf cluster or 5/16 inch star is worn in lieu of another medal. Not more than one award will be made for more than one wound or injury received at the same instant. The Purple Heart is only awarded for combat injuries.
