When I went to Navy boot camp, we had a kid who literally spent the first two weeks bawling. Not crying, not whimpering, but wailing out loud constantly. He'd stop for about ten minutes and then he'd start up again. When we got our hair cut, he was crying. When we got our inoculations, his bald head broke into hives so bad he looked like a sniveling Darth Maul.
They finally sent him to the discharge barracks and separated him as "Unfit for Military Service."
