As many other U.S. military awards, the Purple Heart is meant display the outstanding achievements of the American army men. It's a United States military decoration awarded to those wounded or killed in combat while serving, on or after April 5, 1917, with the U.S. military.

Prior to becoming President of the US in 1961, John F. Kennedy was a Lieutenant in the US Navy in World War 2 serving in the Pacific. He was Commanding Officer of Motor Torpedo Boat PT-109 which collided with and was sunk by a Japanese destroyer in August 1943. As a result of being injured in the collision, he received the Purple Heart award, and so did another million soldiers of World War 2. This makes him the only US president to be awarded this military medal.
