Due to time and resource limitations, units are rarely able to achieve and sustain fully trained proficiency on all mission essential tasks (METs) simultaneously. Commanders therefore do which of the following? A. Revise their METs to ensure they can achieve "T" proficiency in all areas. B. Provide division with a list of risks associated with the lack of resources provided to subordinate units C. Prioritize their METs to identify the METs that must be resourced and trained to "T" proficiency
