What is the mission of the Army's Manning Guidance?

The mission of the Army's Manning Guidance focuses on enhancing unit combat readiness. This is essential because combat readiness directly influences the Army's ability to respond effectively to missions and operational requirements. The Manning Guidance serves as a framework for determining how personnel are assigned to units, ensuring that each unit is optimally staffed with trained and capable soldiers. By prioritizing combat readiness, the Manning Guidance supports the Army's overarching goal of maintaining a force that is prepared to accomplish its missions effectively and efficiently.

Additional context about the other options shows that while assessing personal readiness is important, it is more of a component of ensuring combat readiness than the overarching mission itself. Allocating resources across divisions pertains to logistical aspects rather than the specific focus on manning units for combat capability. The aim to reduce personnel numbers may align with budgetary considerations but does not directly tie into the core mission of enhancing readiness, which remains the primary focus of the Manning Guidance. Thus, the correct emphasis is on ensuring that units are combat-ready, as stated in the chosen answer.
