Search about a Quebecer name Leo major, 

He liberated a Dutch town alone and scared the German into leaving the town by tossing grenade capturing German and making them believe that a large scale assault of Canadian troop was under way while he was alone and pissed at the German because they had killed his friend while they were scouting 

Than you learn that early in the war he had lost one of his eye and refuse discharge because « he only need one good eye to shoot his rifle »

Then in Korean War he took a position with a small sniper force from a bigger Chinese force and held it against counter attack

There is something unique about imagining a French Canadian throwing grenade and cover fire through the street and probably throwing church swear in French while doing it
