Harold A. Marshall (10 February 1918 – 18 January 2013) was a Canadian scout and sniper sergeant who served in the Second World War with the Calgary Highlanders' Scout and Sniper Platoon. On 30 January 1942 the Hamilton Spectator mentioned him in an article about ongoing training simulations the Highlanders were engaged in at an undisclosed location in England. He was wounded on 15 December 1944. In 1973, he was profiled again for Bell's commemorative book Not in Vain, which showed him as a curling enthusiast back in Calgary.
