I understand that in military or police or some other formal situations "jawohl" is the positive response to a command, much like "yes sir" in English; but how does a soldier say "no sir"?
In addition, is "jawohl" also used in answering a yes/no question instead of a command? Like, when a soldier is asked by a superior "are you the only child", does he say "jawohl" or "ja", or "ja" followed by something else?
