I wonder if the UK troops will beat a hasty retreat if their precious prince where to take a hit... Or worse, maimed by a roadside bomb along the streets of Iraq. Can a seriously injured royal still become King?.... Hmm...
What's unusual? Many members if the Royal Family served in their armed forces. For instance, Prince Andrew served in the Falklands War. Prince Charles was a naval officer and so is Prince Philip, the Duke of Edinburgh.
