The tradition of military training at Sanawar has always been strong and was of such a high standard that several contingents of boys were enlisted from the school and sent straight to the battlefields of the First World War. In appreciation of this, the school was redesignated in 1920 as the "Lawrence Royal Military School" and, in 1922, the Prince of Wales presented the school with new Colours. This pattern of military service was repeated again during the Second World War and, according to a BBC Radio broadcast on 3 October 1941, more than two hundred Sanawarians had joined up. The school Colour continues to this day to be trooped at the Founders' Celebration in early October, and Sanawar pupils continue to make a major contribution to the defence of the country.
