When I watched the HBO series Band of Brothers, I was struck by how the soldiers, ill-supplied, freezing, and wearily dug into the snowy trenches of Bastogne, still made time to shave. The clean shaven face was and is military policy. Even today, US soldiers, although they must do without hot water and baths for months at a time, still try to get in a daily shave. It might seem like a strange policy to civilians, but requiring the men to be well-groomed is believed to be important in preserving the men?s sense of discipline and the esprit de corps.
