Which type of duty is explicitly stated in regulations or orders?

The correct choice is specified duty, which refers to tasks or responsibilities explicitly outlined in regulations, orders, or directives. This type of duty leaves no room for ambiguity, as the expectations and actions required in performing the duty are clearly communicated. Specified duties are essential in military operations because they ensure that every member understands their role, leading to a more efficient and coordinated effort.

In contrast, implied duties are those responsibilities that may not be directly stated but are understood to accompany one's position. General duties encompass broader categories of responsibilities that may also lack the specific directives found in specified duties. Direct duties can refer to instructions from superior officers or immediate tasks, but they may not necessarily be documented in formal regulations or orders. Understanding the distinction among these types of duties is crucial for effective execution of military responsibilities and adherence to organizational structure.
