Procedure dictates the counseling should be completed by the person’s supervisor–the person who has the ability to direct the Soldier’s daily duties and responsibilities. If you in someway supervise this Soldier or are responsible for supervising his work then it would be appropriate for you to conduct the counseling. Otherwise it would be the Squad Leader’s discretion to handle it however he deems appropriate. There is no specific counseling regulation that covers this issue. You can check out AR 600–20 which reviews how seniority is determined: Time in Grade, Date of Rank, Age, etc.
