Which Army Regulation covers the process of counseling?

The correct answer covers the process of counseling within the Army and is fundamental for the development and leadership of personnel. Army Regulation 600-100 outlines the Army's guidance on leadership and establishes the standards for counseling, mentoring, and the development of soldiers. Counseling is a vital part of a leader's responsibilities, as it provides a structured method for leaders to communicate expectations, provide feedback, and support the professional development of their subordinates.

In contrast, the other regulations listed pertain to different subjects. For example, Army Regulation 700-8 focuses on supply policy, AR 400-5 addresses safety policies, and AR 600-9 covers the Army's body composition program. Each of these regulations serves specific purposes within the Army framework, but they do not encompass the counseling process, making Army Regulation 600-100 the accurate choice for this question.
