What term describes practices that are followed by tradition rather than by law or regulation?

The term that describes practices followed by tradition rather than by law or regulation is "Military Customs." This concept encompasses the traditional behaviors, standards, and norms that have been established over time within the military community. Military customs are informal practices that guide how service members should behave, interact, and conduct themselves in a manner that fosters a sense of camaraderie and respect for hierarchy.

While some terms listed may relate to military operations or procedures, "Military Customs" specifically emphasizes the traditional aspect of practices, which differentiates it from more formalized systems like regulations or laws. Military Protocol refers to specific formalities and procedures for ceremonies and interactions within military contexts, and Standard Operating Procedures are documented processes established for operational efficiency and consistency, which do not necessarily rely on tradition. Hence, "Military Customs" accurately captures the essence of practices rooted in tradition.
