When are sensing terms required to be used?

Sensing terms are critical for clear and effective communication during military operations, particularly in engagements. They are required to be used before any engagement to ensure that all members of a team understand the situation and the actions that will be taken. This establishes a common understanding of the target status, the intended actions, and helps to avoid any misunderstandings that could lead to friendly fire or coordination failures.

By utilizing sensing terms before any engagement, personnel can confirm if a target has been identified, the type of engagement that is planned, and what is necessary to effectively execute the mission. This proactive communication is essential for situational awareness and operational success.

In contrast, the other options imply usage at different stages that do not emphasize the necessity of establishing awareness and coordination before any action is taken, leading to potential confusion during critical moments.
