Which element is not primarily used by leaders to assess proficiency?

Leaders primarily use evaluations, formal reports, and informal feedback as tools to assess proficiency within their teams or units. Evaluations provide structured assessments of individual performance against established standards, while formal reports offer documented insights into the effectiveness of training and operational outcomes. Informal feedback allows for real-time assessments that can be more flexible and responsive to the dynamics of team performance.

Logistical support, on the other hand, is primarily concerned with the resources and infrastructure necessary to conduct operations and training. It includes the management of supplies, equipment, and personnel to ensure that troops are adequately supported. While logistical support is crucial for overall mission success, it does not directly measure individual or team proficiency. Thus, it is not a tool leaders use to assess how well their team members are performing their duties or mastering required skills.
