Today, a doughboy or GI may be called a grunt. Nobody is sure of the exact beginning of the word. But, the best idea probably is that the name comes from the sound that troops make when ordered to march long distances carrying heavy equipment. A member of the United States Marines also has a strange name -- leatherneck. It is thought to have started in the eighteen hundreds. 今天,doughboy或GI也可以被称为grunt.没人能确定grunt这个词到底是什么时候开始使用的.但最合理的解释是,这个词源于部队在负重长途行进中所发出的声音.海军陆战队员同样有个奇怪的名字--leatherneck.这个词被认为是在19世纪出现的.
