The relationship between officers and men should in no sense be that of superior and inferior, nor that of master and servant, but rather that of teacher and scholar. In fact, it should partake of the nature of the relationship between father and son, to the extent that officers, especially commanding officers, are responsible for the physical, mental, and moral welfare, as well as the discipline and military training of the young men under their command.
John A. LejeuneBe kindly and just in your dealings with your men. Never play favorites. Make them feel that justice tempered with mercy may always be counted on. This does not mean a slackening of discipline. Obedience to orders and regulations must always be insisted upon, and good conduct on the part of the men exacted. Especially should this be done with reference to civilian inhabitants of foreign countries in which Marines are serving.
John A. LejeuneWe are all members of the same great family ... On social occasions the formality of strictly military occasions should be relaxed, and a spirit of friendliness and goodwill should prevail.
