“An officer should, at all times, be dignified in his conduct. Dignity is nothing more than the avoidance of coarse behaviour. It requires the control of one’s emotions. To be profane, boisterous, or ‘loud-mouthed’ is to be coarse. An officer who makes a spectacle of himself by being loud, or by losing his temper on slight provocation, quickly loses the respect of his men.”
