They quickly became known instead as "rice burners," due to the Canadians' admiration for their Korean support unit's demonstrated strength and stamina in carrying 55lb loads over rough terrain, sometimes in snow and ice. While dehumanizing the Koreans as machines that ran on rice was a form of contempt, it was condescendingly approved by the men serving at the time as an improvement over the word it replaced.
