Which role has the duty of providing initial written counseling to a Marine within 30 days of establishing the relationship?

The role responsible for providing initial written counseling to a Marine within 30 days of establishing the relationship is the first line supervisor. This individual is typically the Marine's immediate leader, who is most familiar with their day-to-day performance, strengths, and areas needing improvement. By conducting this initial counseling, the first line supervisor sets clear expectations, offers constructive feedback, and establishes a foundation for ongoing communication and development.

Providing written counseling within a specified timeframe is crucial as it not only documents the supervisor's observations and assessment but also ensures that the Marine understands their responsibilities, evaluation criteria, and any resources available for their professional growth. This initial interaction is essential in fostering a supportive environment and promoting the Marine's commitment to their role and the mission.

The other roles mentioned do not typically engage directly in this initial counseling process. The approver usually reviews performance evaluations, the peer evaluator provides feedback from a colleague's perspective, and the unit commander is generally involved in broader leadership and strategic oversight rather than the direct, day-to-day management of individual Marines.
