Prince Henry of Wales (Henry Charles Albert David; born 15 September 1984), commonly known as Prince Harry, is the younger son of Charles, Prince of Wales, and his first wife, the late Diana, Princess of Wales. A grandson of Queen Elizabeth II, he is third in the line of succession to the thrones of the United Kingdom and the other fifteen Commonwealth realms, behind his father and his older brother, Prince William.

Prince Harry holds the rank of Second Lieutenant (known in the regiment as Cornet) in the Blues and Royals regiment of the Household Cavalry of the British Army, the lowest Officer rank just like his brother, Prince William. Harry was a tank commander, trained to lead a 12-man team in four armoured reconnaissance vehicles. After the decision not to send him to Iraq, he retrained as a battlefield air controller, the job he performed in Afghanistan. He was serving on the front line in Afghanistan although he was pulled out on February 29, 2008 after the world media found out about his presence there and the British authorities became concerned for his safety and the safety of those around him. He had served in Afghanistan between December 14, 2007 and February 29, 2008, for a total of 77 days.

Harry's full title is His Royal Highness Prince Henry of Wales, although he is commonly referred to as Prince Harry. As a prince, he does not need a surname (which would be Mountbatten-Windsor, if needed). Like his brother William, however, Harry often uses "Wales" in place of a surname when required.
