What does the commander's expanded purpose provide?

The commander's expanded purpose is integral to aligning the mission with the broader objectives of higher echelon commands. By providing this expanded purpose, the commander ensures that every action taken on the battlefield is not just effective in isolation but also contributes to the overarching strategic goals of the unit and the larger military operation. This alignment is critical for maintaining coherence in tactics and ensuring that resources are utilized effectively.

Additionally, an expanded purpose helps subordinates understand the "why" behind their tasks, enabling them to make informed decisions that are consistent with the desired outcome of the operation. This understanding fosters unity of effort and facilitates coordination with other units, ensuring that all actions are synchronized toward a common goal.
