This response is provided based on the information you shared and should not be used as the sole source for making a decision. You should seek guidance from the chain of command, IG, JAG or other certified agencies before making any decisions. How you chose to use this information is totally up to you and is your sole responsibility.
The 1SG is counseled by their rater and senior rater like any other leader receiving and evaluation report. Typically the Rater is the Company Commander, and the Senior Rater is either the BN XO, or BN CDR.
With that said some CSMs provide verbal or written guidance to the 1SG. If this is the case and there is a conflict between what the rater has directed and the CSMs guidance then the 1SG needs to seek clarification. HOPE THIS HELPS
