What is the Navy term for taking attendance or roll call?

The term "muster" is a Navy-specific term used to refer to the process of taking attendance or roll call among personnel. During a muster, individuals are typically accounted for to ensure that everyone is present and to assess readiness, especially before beginning operations or activities. This practice is fundamental in maintaining unit cohesion and accountability within the Navy.

The term is deeply rooted in naval tradition and is not just about counting personnel but also involves a ceremonial aspect, often done on deck or in designated areas. "Muster" signifies more than just attendance; it reflects the discipline and organization vital to military operations. Other terms like "count," "check-in," and "register" may convey similar actions, but they lack the specific recognition and ceremonial connotation associated with "muster" in a naval context. This makes "muster" the most appropriate and accepted term for roll call within the Navy.
