The 190th Fighter Squadron, Blues and Royals friendly fire incident was a friendly fire incident involving two United States Air Force (USAF) Air National Guard 190th Fighter Squadron A-10, and vehicles from the United Kingdom's D Squadron, The Blues and Royals of the Household Cavalry, and took place on 28 March 2003 during the invasion of Iraq by armed forces of the United States and United Kingdom.
