The atmosphere of a Navy or a ship is created by the attitude of the officers. Officers are obligated to insure that each of their subordinates knows that the senior officers, and the Navy, do care about men as individuals. Each person in the Navy must have assurance that his progress, his training, his career, and his performance of duty are of concern to the Navy.
Slackness in Command. All major catastrophes in the loss of discipline in all organizations have been preceded by a general slackness in the command. The old saying that a taut ship is a happy ship is still true. The reason is that on a taut ship the officers and the men know where they stand and what is expected of them. There can be complete dependence on one's associates, for lack of reliability will be brought up with a round turn. On such ships, all men do a day's work, not just the conscientious ones. There are no soft billets in a taut outfit. The officers and the men are on the job and require others to be on the job. Chiselers and transgressors are promptly punished while their offenses are still minor.
