What metric is specifically used to measure a unit's mission readiness?

The metric that specifically measures a unit's mission readiness is METL proficiency. METL stands for Mission Essential Task List, which outlines the critical tasks that a unit must be able to execute in order to fulfill its mission. Proficiency in these tasks reflects the unit's readiness to perform its designated missions effectively, taking into account training, personnel capabilities, and necessary resources.

Unlike annual reports, which typically provide a broader overview of a unit's activities and achievements over a period, or budget evaluations that focus on financial resources and their allocation, METL proficiency directly assesses the unit's capability to accomplish essential tasks. Personnel assessments may contribute to understanding individual readiness but do not encompass the overall mission readiness as effectively as METL proficiency does. Hence, proficiency in executing the tasks on the METL is crucial for determining a unit's operational readiness and effectiveness.
