Every soldier in every army is taught first off to be neat and clean, to keep his clothes in good repair, his buttons sewed on and his shoes polished, his face and hands and body washed, his beard shaved. He is respectful to his officers and stands at attention when he is addressed; he moves with precision about his business, walking as a soldier should, head up, chin in, arms at his sides.
