The future success of the Marine Corps depends on two factors: first, an efficient performance of all duties to which its officers and men may be assigned; second, promptly bringing this efficiency to the attention of the proper officials of the government, and the American people.
John A. LejeuneThe 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. LejeuneFrom the Battle of Trenton to the Argonne, Marines have won foremost honors in war, and in the long eras of tranquility at home, generation after generation of Marines have grown gray in war in both hemispheres and in every corner of the seven seas, that our country and its citizens might enjoy peace and security.
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.
