We had a similar situation, we had an AGR NCO that was a personnel SGT that was doing such a poor job at maintaining her unit's records and other responsibilities that we ended up taking her company from her and putting her to work in other areas

. Since this was her first tour (the first tour is kind of like a trial period), we had been counseling her often and had the counselings, e-mails and reports to support our claims of her inefficiency.
One thing I found on the Reserve side of the HRC website is the "ACTIVE GUARD RESERVE (AGR) PROGRAM Commanders' Guide for Handling Substandard Soldiers". If you are logged into the HRC website it can be found at:

I have attached it also. Hope this helps.
