Military courtesy and discipline are important aspects of military life that help to maintain order, structure, and respect within the military. Military courtesy refers to good manners and politeness in dealing with other people, and it provides a basis for developing good human relations. It is an extension and formalization of courtesies practiced in everyday life, and it is intended to reinforce discipline and the chain of command by defining how soldiers will treat their superiors and vice versa. Some examples of military courtesies include proper forms of address, such as "Sir," "Maam," and "Mister," and when each should be used; the salute and the related concept of standing at attention; proper wear of military headgear; obeisance; and the rules for behavior in various ceremonies. Specifics can vary depending on an individuals rank, location, and circumstances.

Military discipline, on the other hand, refers to the training that develops self-control, character, and efficiency in a soldier and creates a willingness to obey orders. It is the foundation of military life and is essential to the welfare of the group. Military discipline is maintained through the use of customs, courtesies, and ceremonies, which help to keep order and structure in the military. Violations of military customs and courtesies can result in official censure or disciplinary action.

In summary, military courtesy and discipline are important aspects of military life that help to maintain order, structure, and respect within the military. Military courtesy refers to good manners and politeness in dealing with other people, while military discipline refers to the training that develops self-control, character, and efficiency in a soldier and creates a willingness to obey orders.
