Final answer:
Planners use the Weighted Metrics Planner (WMP) and the applicable Air Force Manual (AFMAN) to compute rations for a given operation. The AFMAN provides guidelines that help plan logistics efficiently and effectively in the USAF.
Step-by-step explanation:
The question you asked pertains to the computations that planners make for rations using the Weighted Metrics Planner (WMP) and the applicable Air Force Manual (AFMAN). The correct answer is option a) AFMAN. AFMAN refers to a set of regulations and guidelines used by the United States Air Force (USAF) for operations, including planning and logistics for rations. When planners are computing rations, they take into account various factors such as the number of personnel, mission length, and specific needs of the operation. The WMP is used in conjunction with the AFMAN to tailor these computations to the particular requirements.
