Uh, a “short round” is an artillery shell that falls short and lands on friendly soldiers. I don’t know how that could possibly be an ethnic stereotype. It seems to me he was named (edit: nicknamed to be clear) for being chaotic and disruptive, much like an unexpected artillery shell landing in your midst.
