Canada's participation in the War in Afghanistan saw many soldiers from the regiment deploy in a variety of roles throughout the conflict. On September 24, 2007, the King's Own suffered its first combat fatality since the Second World War, when Cpl Nathan Hornburg was killed in action while serving in Kandahar province. Cpl Hornburg was posthumously awarded the "Mention in Dispatches" for his exemplary performance in combat. As a result of the unit's contribution to the War in Afghanistan, The King's Own were awarded the battle honour in 2014, which the regiment now proudly displays on their guidon.
