What does the term "Should" convey in directives?

The term "Should" in directives conveys a recommended action. It implies that while following the guidance is advisable and preferred, it is not strictly mandatory. This term allows for some flexibility, indicating that there may be circumstances under which the recommended course of action could be deviated from, but that doing so is generally not advisable. It suggests that following the recommendation will likely lead to the best outcome or most efficient process, which is why it is seen as a best practice.

In structured situations like military or aviation operations, understanding this distinction is crucial because it helps personnel prioritize actions and understand the implications of their decisions. It encourages compliance without making the action absolutely obligatory, allowing for judgment based on the specifics of a situation.
