What essential information must a mission statement address?

A mission statement is a foundational element in tactical planning as it provides clear guidance and context for the objectives of a mission. The correct answer encompasses the essential components that a mission statement should address: who is involved, what the mission is about, when it takes place, where it is to be conducted, and why the mission is necessary.

Each of these elements plays a critical role in ensuring that everyone involved understands the scope, purpose, and necessary actions related to the mission. "Who" identifies the personnel or units involved, "what" describes the nature and goals of the mission, "when" outlines the timing and scheduling, "where" specifies the geographic location, and "why" explains the rationale behind the mission—its importance and intended impact.

This comprehensive approach ensures that all participants are aligned in their understanding and execution of the mission, which is fundamental for effective tactical planning.
